What is property under renovation insurance?
Property under renovation insurance keeps a single property insured while it is being renovated, refurbished, extended or converted, at the point when a standard home, buildings or landlord policy would restrict or void cover because the building is under major works and often left empty. It insures the existing structure on a rebuild basis, the works and materials being carried out and any extension, plus the property while it is unoccupied during the project, and it adds public liability for the site, contractors and neighbours. An owner, landlord or investor doing up a property tells the insurer before work starts and arranges a specialist renovation policy for the length of the project, so a loss to the existing building or to the works is covered rather than declined.
The moment a property goes under significant renovation, the cover an owner already holds tends to fall away. A standard home, buildings or landlord wording is written for a finished, occupied building, so once internal walls come down, the roof is opened up or the property is cleared for the works, insurers commonly restrict or suspend cover, and a claim made in that period can be turned down. This is a different job from insuring a settled building under an ordinary commercial property insurance policy, and it is why a specialist renovation policy is arranged to carry the building, the works and the liability from the first day on site through to completion.
The property is usually empty while the work is done, and an empty building is a heightened risk in its own right: theft of materials and newly fitted kitchens or boilers, vandalism, escape of water from disturbed plumbing, and squatting. Renovation cover pairs the works with unoccupied-property cover and the conditions that come with an empty site, such as regular inspections and securing the building. Who carries out the work also shapes the policy. A landlord refurbishing between tenancies may move from a commercial landlord insurance policy onto renovation cover for the duration, while a homeowner or investor using a builder, or working on the property themselves, needs public liability for the site, the scaffolding and the neighbours.
Getting the sum insured right matters more here than on a finished building. The existing structure is insured to its full rebuild, or reinstatement, cost, and the value of the works is added on top so the figure reflects the finished property. Under-declare it and an insurer can apply "average", cutting a claim in proportion to the shortfall. The scale of the project drives the terms too: a cosmetic refurbishment such as a new kitchen, bathroom or redecoration is treated more gently than structural work like removing walls, an extension, a loft or basement conversion, or underpinning, where the building is more exposed while the work is under way.

How property renovation insurance works
Describe the project
Share the property, its rebuild cost, the value and type of works, how long the project runs, whether the building is empty and who is carrying out the work. Accurate answers bring back sharper quotes from the underwriting panel.
Weigh up specialist quotes
Your details reach brokers who rate renovation and unoccupied risks every working day. They price the existing structure, the works, the empty-property cover and the public liability against your project rather than a generic profile.
Put cover in place before work starts
Set the policy up to run from the first day on site through to completion, matched to the job: a short refurbishment, a structural build, an extension or a full renovation, with the unoccupied conditions agreed from the start.
What property renovation insurance covers
A home, buildings or landlord policy commonly restricts or falls away once a property is under major works or left empty, which is exactly when a renovation runs. Property renovation insurance keeps the building insured all the way through the project, pairing the existing structure and the works with the cover an empty site needs. Every policy is arranged through FCA-regulated UK brokers on the MyMoneyComparison.com panel.
The existing building and the works, both insured while the property stands empty
Cover one
The existing structure
The building already standing, held on a rebuild (reinstatement) basis through the project, so a fire, flood or storm loss during the works is met against the cost of putting the property back.
Cover two
The works being carried out
The refurbishment or building work itself, along with materials on site and any extension, so a loss to the new work is covered as well as a loss to the original building.
Unoccupied-property cover while it is renovated
A property is usually empty during the works, and an empty building is a heightened risk. This cover carries the property through the vacant stretch, and it comes with the conditions an unoccupied site needs kept.
Public liability for the site and the owner
Protection against a claim for injury or damage to the public, to neighbours or to their property arising from the works, including scaffolding, contractors on site and the boundary. A limit is set when the policy is arranged.
Contents and fittings
Where furnishings, kitchens, bathrooms or fixtures remain in place during the works, cover extends to the contents and fittings held at the property, not only the fabric of the building.
Options where labour is engaged Add on
Employers' liability is a legal requirement where you take on labour, and the policy can be arranged in joint names with a builder so the works and the site are covered on one contract.
Tell the insurer before the works start, then weigh the structure, the works, the empty-property cover and liability on one policy.
Compare property renovation insurance quotesWhat property renovation insurance does not cover
A renovation policy is priced around what you declare: the type and scale of the works, how long they run, whether the building is empty, who is carrying them out and the sum insured on the existing structure and the works. Drift outside those terms and the cover can fall away. Reading the limits matters as much as reading the cover, because breached empty-property conditions, under-insurance and facts left off the proposal are the most common reasons a renovation claim is cut back or turned down.
Wear, tear and gradual damage
Loss caused by age, general deterioration, a slowly operating cause, rot, damp or corrosion in the existing structure falls outside the policy. Renovating a run-down building does not turn pre-existing decay into an insured event. Cover answers sudden, one-off damage during the works, not the tired condition the project is meant to put right.
Breaching the empty-property conditions
Because the building is usually empty during the works, a renovation policy carries unoccupied conditions: regular inspections, securing the site, and often draining down the water. Miss those steps and a theft, vandalism or escape of water claim can be cut back or refused, even while the cover is otherwise live for the project.
Not declaring the works or their scale
The insurer must be told before work starts, and told the true scope: structural alterations, an extension, a loft or basement conversion, underpinning, listed status, past subsidence or flooding, and asbestos. Under the Insurance Act 2015 a claim can be reduced or refused, and the policy voided, where the works or the building are misrepresented.
Under-insurance of structure and works
Insure the existing structure to its full rebuild cost and add the value of the works, so the sum insured reflects the finished building. Set it too low and the average clause bites, cutting the payout in line with the shortfall. Work to rebuild and works value together, not the market or resale price.
Faulty workmanship and defective work
Poor workmanship, faulty design and defective materials, and the cost of putting bad work right, sit outside the policy. Cover answers sudden insured damage to the building and the works, not a contractor's mistakes. Where a builder holds their own liability and contract works cover, that responsibility stays with them.
The contractor's tools, plant and kit
A builder's tools, hired-in plant and their own equipment are usually their responsibility, not the property owner's renovation policy. Agree before work starts who insures the works, the materials on site and the contractor's kit, so nothing falls into a gap between the owner's cover and the builder's.
What is excluded shifts from insurer to insurer and project to project. Read the wording on empty-property conditions, the sum insured, the scope of works and disclosure closely before you commit.

Renovation project types
Types of renovation project we cover
Renovation cover is shaped by three things: the scale and type of the works, whether the building stays occupied, and how long the site is standing empty. Projects run from a light cosmetic refurbishment through to a full structural gut and refit, and the heavier the works, the more the policy leans on unoccupied-property terms and the value of the works being added to the sum insured.
The six project types below sit along this scale. Where a project falls decides how much of the risk is structural, how long the property is likely to be empty, and how the existing building and the works are insured together.
Cosmetic refurbishment
Redecoration, a new kitchen or bathroom, flooring, rewiring and finishes, with no change to the structure. The lightest end of the scale and often carried out while the property is still lived in.
What shapes the cover: the value of the works added to the sum insured, and whether the property stays occupied during the job.
Structural alterations
Removing or moving internal walls, inserting beams and reconfiguring the layout. The building is opened up and often cleared, so the works reach the structure itself and building control usually gets involved.
What shapes the cover: the structural nature of the works and how much of the property is emptied while walls are down.
Extension
Adding to the building with a single or double-storey extension, wraparound or garden room. Groundworks, foundations and a new junction with the existing structure bring in party-wall and works exposure alongside the finished value.
What shapes the cover: the value of the extension added to the rebuild sum insured, plus groundworks and works to the existing wall.
Loft or basement conversion
Turning a loft or a basement into usable rooms. Lofts add dormers, stairs and floor loading; basements bring excavation and underpinning, which sit among the heavier structural risks a renovation can carry.
What shapes the cover: the depth of structural work, and with basements the excavation and underpinning risk to the existing building.
Full renovation
A whole-property gut and refit, frequently of an empty or run-down building bought to bring back into use. The property is usually stripped and stands unoccupied for the length of the project, so the empty-building risk runs throughout.
What shapes the cover: the property being unoccupied throughout, the existing structure insured alongside the full works, and the length of the build.
Change-of-use conversion
Converting a building to a different use, such as an office or barn into homes, or a house into flats. Structural works combine with a change of occupancy class and planning, and the property is typically empty until the new use is ready.
What shapes the cover: the change of occupancy class, the structural works involved, and the building standing empty until the conversion completes.

Insuring the property to the right value during a renovation
A renovation sum insured has two parts that are easy to get wrong. The existing structure must be covered for what it costs to rebuild, not what it would sell for, and the value of the works has to be added on top so the figure keeps pace with the finished property. Insure for less than the two combined and the "average" condition cuts every claim in proportion to the shortfall.
The existing structure: rebuild cost, not market value
The building plus its land on the open market, driven by location, demand and planning. Put the same property on a weaker street and it might fetch just £250,000. Neither figure tells you what it costs to rebuild, because the land is never lost in a fire or flood, and a run-down property bought cheaply to renovate can sell for far less than it costs to reinstate.
What it would cost to demolish and reconstruct the structure as it stood, at today's materials and labour rates, including site clearance, professional fees and the uplift to meet current building regulations.
- Building reconstruction£280,000
- Demolition and site clearance£18,000
- Professional fees£22,000
- Building regulations uplift£15,000
- Project management£10,000
- Existing structure total£345,000
For an older or run-down property being renovated the gap runs the other way from what owners expect: the price paid can sit well below the cost to rebuild, so basing the sum insured on the purchase price leaves the structure under-insured before a single wall is touched.
Then add the value of the works
Insure only the existing structure and the property is under-insured the moment the works add value. The sum insured covers the finished property when it carries both parts: the reinstatement cost of what is already there plus the value of everything being built.
Insure for 70% of the true value, get 70% of every claim
If the property is insured for less than its full rebuild-plus-works value, the insurer applies "average" and cuts the settlement in proportion to the shortfall. Cover it for 70% of the correct figure and the maths below applies to every claim, not only a total loss.
How to set the figure and keep it right
Base the existing-structure figure on a professional reinstatement cost assessment from a RICS surveyor, not the purchase price or a rough guess, then add the value of the planned works on top. A formal assessment typically costs £500 to £1,500. Review the sum insured as the project grows, because building costs have been rising by as much as 7% a year and a scope that keeps expanding quietly slides into under-insurance. Compare property renovation insurance quotes once you have the structure and the works figures in hand.
What impacts property renovation insurance costs
Premiums on a property under renovation spread wide, because no two projects carry the same risk. A short cosmetic refurbishment of an occupied-then-empty flat sits in a different band to a long structural conversion of a listed building left open to the elements. Knowing which factors push the price up or down helps you ask sharper questions before you buy.
Tell the insurer the true scope of the works and how long the property will be empty right at quote stage. Appetite for renovation and unoccupied risks varies more than in most lines of UK insurance. Some insurers steer clear of long structural projects, empty properties or DIY work, while others build their book around exactly those risks. Specialist brokers know which insurer suits which project, so full disclosure points you at the right specialist rather than a declined application further down the line.
MMC Property Renovation Specialists, FCA-authorised (reg. 916241)
Scale and type of works
The single biggest factor. A cosmetic refurbishment, redecoration or a new kitchen or bathroom is treated more gently than structural work: removing walls, an extension, a loft or basement conversion or underpinning, where the building is more exposed while the work is under way.
Sum insured: structure plus works
The existing structure is rated on its full rebuild cost, not resale value, and the value of the works is added on top so the sum reflects the finished property. The higher and more complex the works, the higher the sum insured, and larger projects can call for a survey.
Who carries out the work
A project run by an established builder who carries their own public liability and contract works cover reads differently to DIY or self-managed work, where more of the site liability sits with the owner. Insurers look at experience, references and who insures the works.
Location, flood zone and construction
The existing building still counts. Age and construction, listed fabric, flat roofs and the postcode feed in, alongside Environment Agency flood zones, subsidence-prone ground and local crime. A higher-risk location or an older, more fragile structure lifts the rate.
Length of project and time empty
A short refurbishment carries less exposure than a long structural build, and the longer a property stands empty the more weight insurers place on the unoccupied conditions. Earlier claims, listed status and asbestos come into the picture once a survey is done, and overrunning the agreed period can need the cover extending.
Site security while the property is empty
Securing an empty site brings the rate down: sound locks and boarding, hoarding and fencing, a monitored alarm or CCTV where practical, materials stored away and the water drained down, plus the regular inspections the policy asks for. A well-managed site presents a lower theft and vandalism risk.
Each renovation project is rated on its own scale of works, the sum insured, how long the property is empty, its location and how the site is managed. Compare property renovation quotes to see how your project, your building and your site security shape the premium across our specialist broker panel.
Choose your property renovation cover level
Renovation cover is built up in layers, and most projects group those layers into three levels. Which level fits turns on the scale of the works, whether the property is empty, whether you use a builder or work on it yourself, and the public liability you carry for the site. Most owners land on the Standard package, which stacks public liability, unoccupied-property cover and the works on top of the existing structure.
Structure and works
The floor for any renovation. The existing structure on a rebuild basis plus the works against the usual insured perils while empty, with no public liability, no wider unoccupied extension and no contents. It fits only a narrow set of cases, such as a low-risk cosmetic job managed by an experienced owner.
- Existing structure on a rebuild basis
- Insured perils while the property is empty
- Public liability for the site
- Unoccupied-property cover and conditions
- Contents and fittings
Standard renovation cover
The realistic starting point for most owners and landlords. On top of the structure and works it adds public liability for the site, unoccupied-property cover with its conditions, the materials and any extension, and site security terms during the works. This is where most renovation projects sit, and the shape most insurers quote by default.
- Everything in Structure and works
- Public liability for the site £2m+
- Unoccupied-property cover and conditions
- Materials on site and any extension
- Site security conditions during works
Full project cover
Built for larger projects carrying more exposure. On top of Standard it brings employers' liability where labour is engaged, cover in joint names with a builder, contents and fittings, and legal expenses. It suits structural work, extensions, conversions and full renovations where contractors work on site.
- Everything in Standard
- Contents and fittings included
- Employers' liability where labour is engaged
- Cover in joint names with a builder
- Legal expenses

How much does property renovation insurance cost?
A renovation premium turns on the scale and type of the works, how long the property is left empty and who is carrying out the job, so it moves more than a policy on a finished, occupied home. Rather than quote figures that would not match your own project, the guide below shows where lower, middle and higher renovation profiles sit and what pushes a premium up or down.
A property renovation premium is built from the rebuild value of the existing structure plus the value of the works, the type of works from cosmetic to structural, how long the property stands unoccupied, the security on the empty site, whether a builder or the owner is doing the job, the public liability limit and the claims history. A light refurbishment of a property that stays occupied sits at the lower end. A larger refurbishment with the property empty for a while sits in the middle. Structural works, an extension or conversion, a long-empty or derelict property, or a long project sits at the higher end and is individually underwritten. Every premium is set to the project, so comparing the whole broker panel is how an owner finds the right price.
Cosmetic works, still lived in
where a small renovation sits
A cosmetic refurbishment such as redecoration, a new kitchen or bathroom, with the property still occupied or empty only briefly, standard construction and a clean record. The existing structure, the works and public liability.
Premium moves with- Structure rebuild value and works value
- Type of works and occupancy
- Site security and claims history
Property empty for a while
bigger works, empty for part of the job
A larger refurbishment or a rewire and replumb with the property unoccupied for a stretch, or a modest extension. The empty-property conditions apply, and public liability covers a busier site with trades coming and going.
Premium moves with- Scale of the works and length empty
- Inspections and site security
- Builder or self-managed, public liability
Structural, conversion or derelict
individually underwritten by specialist insurers
Structural works, an extension, a loft or basement conversion, underpinning, a long-empty or derelict property, or a long project. Case-rated by specialist insurers against the whole project rather than a standard table.
Premium moves with- Structural works and conversions
- Length empty and project duration
- Works near neighbours and prior claims
A renovation policy insures the existing structure at its rebuild value, the works and materials, and the owner's public liability, while the property is worked on and often empty. The scale and type of works is the biggest factor, because a cosmetic refresh rates very differently from removing walls, an extension, or a loft or basement conversion. How long the property stands unoccupied matters too, because theft of materials and fittings, vandalism and escape of water all rise while it is empty, so the inspection and security conditions feed into the terms. Underpinning, works close to a neighbour, a listed or period property, and a long project all push the premium up, and using competent, insured contractors and keeping the sum insured right can help the terms.
Important: This page describes what drives a property renovation premium rather than quoting figures, because a premium can only be set against your own property, the works and how long it is empty. Nothing here is a quotation or an offer of insurance. Actual premiums vary by the scale and type of works, the rebuild value and works value, occupancy, site security, who does the work, liability limits, project length and claims history, so always compare several quotes before you buy.

When property renovation claims get paid, and when they get declined or reduced
Most renovation claims settle without a fuss. Where one is cut back or turned down, the cause sits on a short and familiar list: the sum insured did not cover the structure plus the works, the empty-property conditions were not kept to, the scope of the works was never declared, or the loss came down to faulty workmanship the policy does not answer. Whether you collect the full amount or a reduced one is, in practice, settled at the quote stage rather than on the day of the loss.
| Scenario | When the claim is paid in full | When the claim is reduced or declined |
|---|---|---|
| Fire during a refurbishment | Paid The existing structure and the works are insured to their full rebuild and works value, the scope of the project was declared before it started, and the empty-property conditions have been kept to on site. | Reduced Where the sum insured falls short of the structure plus the works, the average clause bites and the payout is scaled back. Works never declared to the insurer, such as an unannounced structural job, can remove cover altogether. |
| Escape of water in an empty property under works | Paid The renovation policy carries unoccupied cover, the inspection and securing conditions have been met, the system was drained down where required, the loss is reported quickly, and it is a sudden burst rather than a slow leak. | Declined Where the empty-property conditions were breached, no regular inspections, or the water left on and undrained, the claim can be cut back or refused. A gradual seep is treated as wear and tear on the old plumbing the project is there to replace. |
| Storm while the roof is open for works | Paid The loss follows a genuine storm backed by wind speed and rainfall records, the open roof had the temporary weatherproofing the policy asks for, and the works were being carried out as declared. | Declined A roof left open and unsheeted against a forecast storm, or pre-existing poor repair, is put down to the works or wear and tear rather than an insured storm, and the claim falls away. |
| Theft of materials and new fittings from site | Paid The unoccupied and theft cover is in place, the site was secured to the standard the policy requires, entry was forced, and a police crime reference was logged when the loss was found. | Declined The site was left insecure against the conditions, the loss cannot be shown as forced entry, or the missing items are the contractor's own materials that sit with the builder's cover. |
| Accidental damage to the existing structure during works | Paid The works were declared, sudden accidental damage to the existing building during the agreed job is insured, and a competent contractor or engineer was overseeing the work. | Declined Damage caused by faulty workmanship, poor design or defective materials is excluded, as is the cost of redoing bad work, and predictable collapse from unsupported structural work is not a sudden insured event. |
| Passer-by injured by scaffolding or falling debris | Paid Public liability of £2m or more for the site is on the policy, the site was fenced and signed, no earlier warning about the hazard was left unaddressed, and reasonable care was taken around the works. | Declined Public liability for the site was left off at quote, the hazard had been flagged before and ignored, or the injury ties back to a contractor whose own public liability should respond. |
A reduced or refused renovation claim nearly always comes down to one of four things: a sum insured set too low to cover the structure plus the works so the average clause applies, the empty-property conditions breached, the scope of the works never declared, or a cover line simply not chosen at quote. At claim stage, loss adjusters commonly ask for rebuild and works valuations, the inspection log, the original declaration and details of who was carrying out the work, checking the policy lines up with the project as it really is.
Specialist renovation brokers build these outcomes into the cover before work starts. Compare property renovation insurance quotes to see what sits in the policy as standard and what has to be endorsed for your own building and project.
How to prepare for a property renovation insurance quote
A broker can rate a renovation accurately only when the picture of the property, the works and the occupancy is clear from the outset. Spend ten minutes pulling together the building details, the scope and length of the works and who is carrying them out before you open the form, and you get sharper quotes, far fewer follow-up calls, and terms that hold for the whole project.
Set out the property and the sum insured
Cover starts with the existing structure, so have the building details and the rebuild figure ready before you begin.
- Address, year built and how it is constructed
- Rebuild figure for the existing structure
- The value of the works and any extension
- Listed status and whether it is a home or a let
Describe the works, the length and who does them
Terms follow the scope of the works, how long they run, whether the property is empty and who is on site.
- Cosmetic refurbishment or structural works
- Start date and how many months the works run
- Whether the property is unoccupied during works
- A main contractor or DIY, and site security

Specialist and higher-risk renovation projects
Not every renovation sits inside a mainstream insurer's appetite. Structural alterations, extensions, loft and basement conversions, underpinning, a long-empty or derelict property, a listed building, works that reach a neighbour's boundary and DIY without a main contractor all move a project into specialist territory. Open any heading below to see how specialist underwriting handles the eight kinds of higher-risk renovation UK owners raise most often.
Structural works and removing load-bearing walls
Taking out load-bearing walls, forming new openings, altering floors or replacing a roof structure changes the risk to the existing building while the works are under way. A collapse, a temporary support failure or damage to what is still standing can turn into a large claim, so the existing structure and the works both need to stay insured through the project.
Specialist renovation insurers rate for the structural stage, the length of the works and whether a structural engineer and building control are involved. A standard home or buildings policy commonly restricts or voids cover once major structural work starts, which is the point of arranging a project policy. See our property renovation insurance guide for specialist cover.
Works close to neighbours and party walls
A terraced or semi-detached property, or works right up to a boundary, brings the neighbours into the risk. Excavation, underpinning, a rear or side extension and demolition can damage an adjoining property or injure someone next door, which is where the owner's public liability for the site matters most.
Party Wall etc. Act 1996 notices and a schedule of condition for the neighbouring property are usually needed before work starts. Specialist renovation cover carries public liability for the owner and, where a contractor is engaged, sits alongside the contractor's own liability so injury or damage to neighbours and their property is insured through the works.
Underpinning, excavation and ground works
Underpinning, lowering a floor, digging out a basement or forming new foundations disturbs the ground the existing building stands on. Movement, cracking or partial collapse during the dig is a real exposure, and the works and the existing structure both need to stay covered while the ground is open.
Specialist insurers rate this properly where a structural engineer has designed the scheme, building control is involved and the sequence of works is controlled. A standard buildings policy will usually exclude damage arising from the owner's own excavation or underpinning, so a project policy is arranged to carry that stage.
A long-empty or derelict property
A property that has stood empty for a long time, or one bought in a derelict state to be brought back into use, sits at the harder end of the market. An unoccupied building draws theft of materials and fittings, vandalism, escape of water and squatting, and standard cover on an empty home or buildings policy usually falls away after a set vacancy period. That is exactly when most claims on an empty site happen.
Specialist renovation cover pairs the works with unoccupied-property cover sized to the state of the building and the length of the project. Insurers ask for documented inspections, the water system drained down and the site secured. See our property renovation insurance guide.
Extensions and new additions
A rear, side or wrap-around extension, a garage conversion or a two-storey addition brings a new element into the risk on top of the existing building. The extension is under construction while the original structure still stands, so cover needs to run across both the works and the finished value they add.
Insure the existing structure to its rebuild cost and add the value of the extension so the sum insured reflects the finished building, or the average clause can cut a claim. Specialist renovation insurers rate the build stage, the length of the works and whether a contractor or the owner is running the job.
DIY and self-managed works without a main contractor
Running the works yourself, or using trades you engage directly rather than one main contractor, changes who carries the risk. There is no contractor's policy sitting behind the job, so the owner needs public liability for the site and needs to be clear about which tasks are self-done and which are subcontracted. Insurers look more closely at hot works, electrics and anything structural done without a professional.
Where labour is engaged, employers' liability is a legal requirement even on a self-managed project. Specialist renovation cover carries the owner's public liability, can be arranged in joint names with a builder where one is used, and rates the works on how they are being managed rather than assuming a single contractor is in charge.
Loft and basement conversions
A loft conversion opens up the roof and adds floor loading, while a basement conversion means digging out below the existing footings. Both alter the structure and leave the property exposed to weather and movement mid-project, so the roof being off or the ground being open is a stage that needs cover in place.
Specialist renovation insurers rate for the open-structure phase, the length of the works and whether a structural engineer and building control are signing off the stages. Escape of water and storm damage while the roof is open are common claims, so a documented programme of works helps the terms.
Renovating a listed or period property
Renovating a Grade I, Grade II* or Grade II listed building brings conservation duties on top of the works. Listed building consent is needed for alterations, repairs must use period materials and heritage trades, and putting right any damage during the works costs well above the rate for a modern build. That pushes the rebuild figure and the sum insured up.
Specialist insurers rate for conservation-grade reinstatement, the longer timeline and the extra care an older structure needs while it is opened up. Being straight about listed status, the scope of the works and any consents at quote stage matters, because the Insurance Act 2015 makes an undisclosed material fact grounds to void the policy.
Every renovation carries its own mix of works, occupancy and risk. Compare property renovation insurance quotes to see how your own property, the scope of the works and who is carrying them out are rated across the MyMoneyComparison.com broker panel.
Who needs property renovation insurance?
It is not only professional developers. Any owner keeping a single property insured while it is refurbished, extended or converted needs specialist cover, because a standard home, buildings or landlord policy can pull back or fall away once the property is under major works or left empty. Each situation below carries its own renovation need.
Homeowners renovating
Doing up a home they own, whether they stay put through the work or move out while the builders are in. The kitchen, bathroom or a full strip-back is under way, and the house may sit empty for weeks at a time.
Their home insurer often restricts cover once major works start or the house is left unoccupied, so they need a policy that keeps the existing building and the works insured for the length of the project.
Landlords refurbishing
Upgrading a let property in the gap between tenancies, from a new bathroom and rewire to knocking rooms through. The flat or house stands empty and off the rent roll while the trades finish.
A landlord policy assumes a tenanted, occupied home, so it commonly cuts back during an empty refurbishment. They need unoccupied-property cover paired with the works and the conditions that come with an empty site.
Investors renovating on
Buying a tired property, improving it, then selling it on or letting it out. The whole point is the works, and the property carries no occupier while the project runs to a deadline.
A loss to either the existing building or the improvement wipes out the margin, so they insure the structure to rebuild cost plus the value of the works, keeping the finished sum insured accurate.
Probate and inherited owners
Doing up a property left to them that has stood empty, often dated or in poor repair. It sits unoccupied through probate and then through the works before anyone lives in it or it is sold.
An empty inherited home is a heightened risk for water damage, theft of fittings and vandalism. They need cover that spans the unoccupied period and the renovation without a gap between the two.
Auction and run-down buyers
Taking on a property that needs work from the day the keys change hands, sometimes bought at auction where cover has to be in place fast. The building may be unmortgageable until the works are done.
Ordinary buildings cover can be hard to place on a property in poor condition, so they need a renovation policy that insures the existing structure and the works from day one of ownership.
Self-managed renovators
Running the project themselves, whether that is hands-on DIY or coordinating their own trades rather than a single main contractor. They carry the risk of the site, the scaffolding and anyone working on it.
With no contractor holding it all together, the owner needs public liability for the site and the works, covering injury or damage to neighbours and the public, and employers' liability where any labour is engaged.
The thread through every case is the same: tell the insurer before works start, because a standard policy can be restricted or voided once a property is renovated or left empty. Match the policy to how yours is owned, occupied and worked on. Compare property renovation insurance quotes for your project.
Renovation insurance vs a standard home, buildings or landlord policy
A standard home, buildings or landlord policy is written for an occupied, finished property. Once major works start and the property is left empty, that cover is commonly restricted or voided, which can leave an owner without valid cover part way through a project. Property renovation insurance keeps the existing structure, the works and the liability insured across the whole job, with the property unoccupied. Here is how the two lines up, point by point.
Leaving a property on a standard policy during a renovation can leave the owner uninsured mid-project. Tell the insurer before works start. A home, buildings or landlord policy is not built for a live site, and once cover is restricted or voided a fire, theft of materials, escape of water or collapse can fall on the owner in full. A specialist policy is arranged for the project instead.
Using a builder or contractor vs DIY or self-managed
Who carries out the work changes what the owner still needs to insure, but it never removes the need for the owner's own cover on the existing structure and the empty property.
Builder or contractor doing the work
Cover shared with the tradeA building firm carries its own public liability and, under the building agreement, may insure the works while they are in progress. That handles the contractor's side of the risk.
DIY or self-managed renovation
No contractor policy behind youManaging the job yourself, or working with sole-trader labour, means there is no main contractor policy covering the works and no firm's public liability standing behind the site.
Not sure your current policy will hold once the works begin? It usually will not. Compare property renovation insurance quotes and keep the building, the works and the liability insured from the first day of the project.
Cover detail shown is indicative of how UK property renovation policies are typically structured. It is illustrative only and is not a quotation. Sums insured, unoccupancy conditions, liability limits and exclusions vary by insurer and individual circumstances.
Renovating within a portfolio or on a bigger project
Renovating one property is straightforward enough on its own, but two situations change how the cover is arranged: a landlord or investor refurbishing a single property inside a wider portfolio, and a larger, longer project than a quick refurbishment. In both, the renovation has to sit alongside the rest of the book, or run for long enough, that a plain single-property policy stops being a tidy fit.
A landlord or investor renovating one property in a wider portfolio can keep that property, mid-works and often empty, on the same schedule as the rest of the book rather than pulling it onto a separate policy. A bigger or longer project, such as a full renovation running many months, is written as a project policy sized to the scope and the length of the works. Both are case-rated against the property, the works and the occupancy, which usually lands on better terms than a short-term stopgap.
Keep the renovation on your existing schedule
A property being refurbished can stay on the same schedule as the rest of the portfolio, flagged as under works and unoccupied, rather than coming off onto a separate policy while the job runs and going back on at the end.
Renovating within an SPV or company portfolio
Where the portfolio is held through an SPV (special purpose vehicle) limited company, a property being renovated stays in the SPV name, with the works and the empty-property status declared. See our property portfolio insurance guide.
Let, empty and mid-renovation together
Tenanted properties, empty ones between lets and a property under renovation can share the same schedule. The cover copes with the different states, including the works and the unoccupied period, without splitting the property being refurbished onto its own policy.
Rated on the scope and length of works
A bigger project is rated on what the works involve and how long they run, not pulled off a standard table. Insurers weigh the rebuild value, the value of the works, whether the property is empty and the state of the building to set the terms.
Public liability across the works and the book
Property owners and public liability can run on limits shared across the portfolio rather than fixed per property, so the site under renovation is covered for injury or damage to the public and neighbours alongside the tenanted properties, without a separate liability policy for the works.
Flagging works partway through the year
A property can be switched to a renovation and unoccupied basis partway through the year, with the premium adjusted pro rata, and put back to a standard let once the works finish and it is occupied again, with no wait for renewal and no separate short-term policy.
Renovating a property inside a portfolio, or running a bigger project, is worth arranging as part of the wider book. Compare property portfolio insurance quotes through a specialist panel used to SPV, mixed-use and multi-property risks.
How to keep property renovation insurance costs down
Insuring a property through a renovation carries the risk of an empty site and live works, but a handful of practical moves genuinely bring the premium down without thinning out the cover or cutting corners on compliance. Securing the property, inspecting it, using competent trades and setting the sum insured properly all count in your favour when the works are rated.
Secure the empty site properly
Sound locks, boarded or shuttered openings, hoarding around the works, alarms and site CCTV all cut theft of materials and fittings, vandalism and squatting while the property stands empty. Visible security on an empty renovation feeds straight into the rate insurers offer.
Use competent, insured contractors
A named main contractor with their own public liability, references, and Gas Safe or NICEIC registration for the relevant trades gives underwriters confidence in how the works will be run. A managed job with insured trades noticeably improves terms compared with unverified DIY.
Inspect the property on a set routine
Regular recorded inspections while the property is empty, with the water system drained down, post cleared and any weather damage caught early, hold down escape of water, theft and storm claims. Meeting the inspection conditions is what keeps the unoccupied cover valid during the works.
Keep consents and certificates in order
Planning permission and building control sign-off where needed, listed building consent, Party Wall Act notices and up-to-date electrical and gas certificates all show the works are being managed properly. Documented consents make a project easier to place and to rate.
Set the sum insured at the right level
Insure the existing structure to its rebuild cost and add the value of the works and any extension, so the sum insured reflects the finished building. Getting this right avoids the average clause cutting a claim, and avoids paying for cover you do not need on an over-stated figure.
Use a specialist renovation broker
Generic comparison sites struggle here because insurer appetite swings so widely by the scope of the works, how long they run and whether the property is empty. Specialist brokers work this market every day and rate it properly across niche insurers and Lloyd's syndicates.
The biggest savings come from stacking two or three of these together rather than relying on one. Compare property renovation insurance quotes to see what your own property, the works and how you manage the site add up to across the specialist panel.
Specialist Property Renovation Insurance
Comparing specialist property renovation insurance since 2013
MyMoneyComparison.com has been helping UK property owners find cover without the runaround since 2013. Renovate a newly bought home, refurbish a let property between tenancies, bring an inherited or probate property back into use, or extend and convert a building you own, and the same specialist broker panel insures properties under renovation every day. Compare specialist renovation cover from a panel that knows the existing structure, the works, unoccupied-property risk, public liability and the full spread of UK commercial property insurance risks.
Generic comparison sites versus specialist renovation brokers
Standard comparison sites are built around home insurance and cover for a finished, occupied building. A property under renovation sits outside that profile, which is why specialist brokers repeatedly rate the same risk more keenly and with cover that actually answers the works, an empty site, the existing structure and the public liability mainstream insurers restrict or exclude.
Standard home and buildings aggregators
Geared to a finished, occupied home or a simple buildings policy. A property under renovation is usually treated as a non-standard risk, then either turned away or priced at the loaded end of the panel without the works and the empty site being understood.
Typical limitations- Cover restricted or voided once works start
- Unoccupied property often turned away
- The works and materials not covered
- Structural works and extensions left out
- Owner public liability for the site missing
Specialist property renovation brokers and underwriters
FCA-regulated brokers who insure properties under renovation day in, day out. The existing structure, the works and materials, unoccupied-property cover and owner public liability are on the policy from the start, sized to the property, the works and the occupancy you declare.
Built around property under renovation- Existing structure insured through the works
- The works, materials and any extension covered
- Unoccupied-property cover during renovation
- Public liability for the owner and the site
- Cosmetic, structural, extensions and conversions
A quote from a generic home or buildings comparison site can look sharp yet leave out the cover a property under renovation actually needs. Keep a standard policy running through the works and you may find cover restricted or voided the moment the property is empty or the structural work starts, the works and materials uninsured, or public liability for the site absent, and that is precisely the pattern that leads to reduced or refused claims under the average clause and the Insurance Act 2015. Before the works begin, tell the insurer and check the policy covers the property, the works and the empty site you genuinely have.

Everything You Need to Know
Clear answers to the questions that come up most often about property renovation insurance.
What is property renovation insurance?
Property renovation insurance keeps a single building insured while it is being renovated, refurbished, extended or converted. It sits in place of ordinary home, buildings or landlord cover for the length of the project, insuring the existing structure, the building works and the materials on site, along with the owner’s liability. Bought by an owner, landlord or investor rather than a professional developer, it pairs standard property perils such as fire, storm, flood and theft with unoccupied-property cover, since the building is usually empty while the work is carried out.
Why won't my standard policy cover a renovation?
A normal policy is written for a finished, occupied building, so major works and an empty property both fall outside what it will accept. Most wordings cut back or end cover once building work passes a stated value or the property is left unoccupied beyond a set number of days, which can leave a claim unpaid at the worst moment. Telling your existing insurer the property is being renovated will often see the policy restricted or cancelled, so a specialist renovation policy takes over and insures the building through the works instead.
Do I need to tell my insurer before work starts?
Yes, and it is worth arranging cover before the first tools arrive. A standard home, buildings or landlord policy can be restricted or voided once a property goes under major renovation or is left empty, so the specialist policy needs to be in place from the day works begin. Give the insurer the scope of the project, its value, how long it will run and whether the property will be occupied, so the cover matches the work. Starting a structural project on ordinary cover, or leaving the insurer in the dark, is the most common way a renovation claim is refused.
Does it cover the existing structure during works?
Yes. The existing building is insured on a rebuild basis throughout the project, so damage to the standing structure from fire, storm, flood, escape of water or theft is covered while the work goes on. This matters because the existing fabric is often the most valuable thing on site and is at greater risk during works, with roofs opened up, walls removed and services disconnected. The sum insured should reflect the full cost of reconstructing the finished building, not the price you paid for it.
Does it cover the works, materials and an extension?
Yes. Alongside the existing structure, the policy insures the building works themselves, the materials and fittings waiting to be installed, and any extension being built, so a loss to the new work is covered as well as the old. Cover typically runs while materials are stored on site and as they are fixed into the building. On a larger project the works can be insured in joint names with the builder, so both parties have an interest in the same policy and a dispute over who pays is avoided.
Can I insure a property that is empty while renovated?
Yes, and this is central to the product. A property being renovated is usually empty, and an empty building is a heightened risk of theft of materials and fittings, vandalism, escape of water and squatting, which is why ordinary cover pulls back once a property stands vacant. Renovation insurance pairs the works with unoccupied-property cover so the building stays insured while nobody is living or trading there. Expect the policy to carry conditions that go with an empty site rather than the open terms of an occupied building.
What conditions apply to an empty property during works?
Because the property is unoccupied, the policy sets conditions the owner must meet to keep cover live. These commonly include regular recorded inspections, securing the building and its openings against entry, draining down or isolating the water supply where practical, removing obvious valuables, and keeping the site tidy and free of build-up that could feed a fire. Failing to keep to these terms can reduce a payout or defeat a claim, so read the unoccupancy conditions carefully and diarise the inspections from the day the property is left empty.
Cosmetic refurbishment or structural works?
The line falls between changing how a building looks and changing how it stands up. Cosmetic refurbishment, such as redecorating, a new kitchen or bathroom, rewiring or replastering, leaves the structure intact and is treated as lower risk. Structural work, such as removing or moving load-bearing walls, building an extension, converting a loft or basement, or underpinning, alters the fabric and carries more risk, so it shapes both the cover and the terms. Tell the insurer which you are doing, because a project described as cosmetic that turns structural can fall outside the policy.
Are extensions and loft or basement conversions covered?
Yes, these structural projects can be insured, though they need to be declared as structural rather than cosmetic. An extension, a loft conversion or a basement dig-out changes the building and the works value, so the sum insured has to grow to include the new space, and the insurer will want the scope and duration up front. Basement work in particular raises the risk of escape of water and ground movement, so terms and excesses can reflect that. Cover the existing structure and the new work together so a loss to either is met.
What about underpinning and works next to a neighbour?
Underpinning and work close to a boundary raise the risk to the property and to the people and buildings around it. The existing structure is insured while the ground is stabilised, though a history of movement can tighten the terms. Just as important is the liability side, because digging, scaffolding and demolition near a neighbour can damage their property or injure a passer-by. Public liability responds to that, and where the work affects a shared or boundary wall a party wall agreement with the neighbour is a separate legal step that sits alongside the insurance.
If I use a builder, who insures the works?
It depends on how the project is run. A main contractor working under a building contract will often carry the works and their own public liability, so ask to see their cover and check whether it names you and runs to the full value of the project. On smaller jobs, DIY or self-managed work, the responsibility falls to you as the owner, so the renovation policy needs to insure the existing structure, the works and your liability. Where a builder is engaged, the works can be arranged in joint names so both of you are covered under one policy.
Do I need public liability while renovating?
It is strongly advised for anyone running a renovation. Public liability meets the cost of compensation and legal defence if the works injure a member of the public or damage property belonging to someone else, such as a neighbour hurt by falling material or a next-door wall cracked by the work. A renovation site brings scaffolding, deliveries, contractors and open ground into play, all of which raise the chance of a third-party claim. Cover is commonly written with an indemnity limit of £1m, £2m or £5m, chosen to suit the site and its surroundings.
Do I need employers' liability?
If you engage labour on the project, employers’ liability is a legal requirement, not an optional extra. It covers claims from workers injured or made ill by the work you have them do, and the law sets a minimum indemnity limit of £5m. A genuinely independent contractor who carries their own cover may not count as your employee, but casual or paid help engaged directly by you usually will, so check the position before anyone starts. Arrange the cover as part of the renovation policy where you are taking people on.
How do I set the sum insured, and what is average?
Insure the existing structure at its full rebuild, or reinstatement, cost and add the value of the works, so the sum insured covers the finished building rather than the price you paid. Rebuild cost takes in materials, labour, professional fees and meeting current building regulations, and never the land beneath. If you set the figure too low, the insurer can apply average and scale the payout down in proportion: cover the building for only 70% of its rebuild cost and a claim is cut to 70% of the loss, on a partial claim as much as a total one.
How long does cover last if the project overruns?
Renovation cover is usually written for the expected length of the project, often in terms of 6 or 12 months, matched to your build programme. Set the period against a realistic timescale rather than the best case, because works frequently run over. If the project overruns, contact the insurer or broker before the policy lapses to extend the term, since cover falling away mid-build leaves the structure, the works and your liability exposed. Once the property is finished and occupied, it moves onto an ordinary home, buildings or landlord policy.
Can I insure a newly bought or inherited property?
Yes, and a recently bought or inherited property is one of the most common reasons this cover is arranged. A house bought at auction or through probate is often empty and in need of work before it can be lived in, let or sold, which is exactly the point at which ordinary cover will not respond. A renovation policy insures the building from completion or the grant of probate, through the works, while it stands empty, and up to the day it is finished and occupied or sold on.
Can I insure a let property between tenancies?
Yes. A landlord refurbishing a property between tenancies faces a gap where the building is empty and under works, so a standard landlord policy will usually restrict or suspend cover. A renovation policy bridges that gap, insuring the structure and the works while the property is unoccupied and no rent is coming in. Once the refurbishment is finished and a new tenant moves in, the property returns to an ordinary landlord policy. Tell the insurer the property is being refurbished rather than simply void, so the works are covered too.
Can I insure a listed property under renovation?
Yes, though a listed or period property needs a specialist policy rather than a standard one. Reinstatement has to be priced on a like-for-like conservation basis using period-appropriate materials and heritage trades, so the rebuild figure sits well above that of a modern building of the same size. Works to a listed building also carry consent requirements, and the insurer will want the scope and the trades involved. Insure the existing historic fabric and the works together, and set the sum insured on a proper conservation reinstatement figure.
Is property renovation insurance a legal requirement?
The buildings cover itself is not required by law, but two things around it can be. Employers’ liability is a legal requirement the moment you engage labour on the project, and a mortgage lender will almost always make insuring the building a condition of the loan. Beyond that, running a renovation without cover leaves the existing structure, the works and your liability to a neighbour unprotected, which is a serious risk to take on a property that is often your largest asset. Most owners treat the cover as essential even where no rule forces it.
How is the cost worked out?
A premium is built from the features of the individual project rather than a set rate. The main factors are the rebuild value of the existing structure and the value of the works, the type of work, cosmetic or structural, how long the project runs, whether the property is occupied or empty, the postcode and its flood and subsidence exposure, and the level of public liability chosen. Who carries out the work and whether a builder holds their own cover also count. The dependable way to gauge cost is to compare quotes from FCA-regulated brokers against your own project details.
How can I reduce the cost?
Several steps can hold the premium down without thinning the cover. Give an accurate rebuild and works value so you are neither over-insuring nor risking average, keep the project period realistic so you are not paying for months you do not need, and improve site security with proper locks, boarding, fencing and lighting to cut the theft and vandalism risk on an empty site. Meeting the unoccupancy conditions, using a builder who carries their own liability, and comparing several FCA-regulated brokers rather than taking the first quote all help as well.
How do I compare property renovation insurance quotes?
Renovation risks sit outside the mainstream, so a home-insurance comparison panel tends to decline once it sees an empty property under structural works, or hands back a price loaded to the top of its range. A broker who arranges renovation cover every day reads the project properly, matches the existing structure, the works and the liability to the right terms, and can reach specialist insurers that rate the risk on its merits. MyMoneyComparison does not advise or sell, but puts you in touch with FCA-regulated UK brokers who arrange this cover. Start by comparing property renovation insurance quotes with your project details to hand.
