Property Developers Insurance

contract works, site liability and existing-structure cover for a new build, conversion or refurbishment

Project cover for a developer, from bare site to finished building. The building contract and the value of the works shape the policy as much as the risks on site do.

  • New build, conversion and refurbishment
  • Contract works and site liability
  • Single project or annual cover
  • FCA authorised and regulated

Quick answerProperty developers insurance covers a building project run to sell or let, such as a new build, a conversion or a refurbishment. Its core is contract works cover for the works, materials and work in progress on site. Alongside it can sit cover for any existing structure, public and employers’ liability, plant, and the finished building until it is sold. Tell MyMoneyComparison.com about the project once, and specialist UK brokers can come back with quotes.

This page is about development projects. A homeowner or landlord doing up a single property is on our property under renovation insurance page, and a building contractor’s own cover on construction company insurance.

The basics

What Is Property Developers Insurance?

Project cover for a developer building, converting or refurbishing property. It insures the works as they progress, any existing structure, and the developer’s liability on site.

Contract works

The new or converted structure, materials and work in progress.

The existing structure

A building being converted or refurbished, for its rebuild figure.

Public liability

Injury or damage to the public, neighbours and nearby property.

Employers’ liability

Site staff and labour-only subcontractors, where you take them on.

Plant and tools

Owned and hired plant, tools and site huts.

Completed buildings

A finished property held empty until it is sold or let.

How it works

How Does Property Developers Insurance Work?

You describe the project and its value, the insurer sets the cover and site conditions, and the policy runs for the project or for a year of projects.

  1. You describe the project

    New build, conversion or refurbishment, the site, the build programme and who is doing the work.

  2. You set the sums insured

    The completed value of the works and, for a conversion, the rebuild figure of the existing structure. The method is in our guide to calculating a rebuild value.

  3. You choose single project or annual

    Cover for one development, or an annual policy for a developer running several sites.

  4. Cover runs to completion and beyond

    Through practical completion, and then for the finished building until it is sold or let, where included.

What it covers

What Does Property Developers Insurance Cover?

The works as they go up, materials on site, any existing structure, and liability to the public and site staff, with plant and completed buildings on many policies.

The sections of a UK property developers policy
SectionWhere it sitsWhat to know
Contract worksCoreTo the completed value of the works
Materials on site and in transitCore or optionalCheck any limits for items off site
The existing structureFor conversionsFor its full rebuild figure
Public liabilityCoreThe limit is set on your schedule
Employers’ liabilityWhere you take on labourCovers site staff and labour-only subcontractors
Owned and hired plantOptionalIncluding hired-in charges on some policies
Completed, unsold buildingsOn some policiesUntil sale or letting, with conditions

The value rises as you build. The contract works figure needs to reach the completed value of the works, not the cost on day one, or a claim can be reduced for under-insurance.

Exclusions

What Property Developers Insurance Does Not Include

Cover can exclude faulty design or workmanship, losses where site conditions were not kept, gradual damage, and changes to the project the insurer was not told about.

Faulty design or workmanship

Putting right the defect itself, though resulting damage can be covered.

Undeclared changes

A bigger or different project than the one described.

Hot work breaches

Fire where hot work conditions were not followed.

Unsecured site

Theft where plant or materials were left unprotected.

Wear, tear and gradual damage

Decay already in an existing building.

Penalties and delay costs

Contract penalties and lost profit, unless added as an extra.

Types of project

Which Development Projects Can Be Covered?

From a single new home to a multi-unit scheme, conversion or refurbishment. The type, value and stage of the project shape the terms.

New builds

Single homes and small or larger residential schemes.

Conversions

Houses into flats, barns into homes, offices into apartments.

Refurbishments

Buildings stripped back and refitted for sale or letting.

Change of use

Commercial buildings turned residential, or the reverse.

Mixed-use schemes

Shops or offices with homes above.

Completed stock

Finished units awaiting sale or tenants.

Developer or renovation

Developer Cover vs Renovation Cover

Renovation cover suits an owner doing up one property. Developer cover is designed for projects run to sell or let, with contract works, site liability and plant at its core.

Cost

What Property Developers Insurance Is Priced On

The type and value of the project, the build programme, the site, who does the work, the liability limits and the claims history. We do not print average premiums.

Why the project leads

The completed value of the works sets the base, and structural work, height and timber frame can change how an insurer sees the risk.

Why the people matter too

Your experience as a developer, and the contractors and subcontractors you use, feed the terms.

The conditions

The Contract and Site Terms That Decide a Development Claim

Development claims can turn on the building contract and the site conditions. Four come up again and again.

  1. Settle who insures the works

    The building contract can say whether the developer or the contractor insures the works, and whether in joint names. Match the policy to it.

  2. Keep the sums insured up to date

    Review the contract works figure as the project grows, and tell the insurer about variations.

  3. Follow the hot work and security rules

    Keep to any conditions for welding and cutting, lock plant away, and secure the site out of hours.

  4. Check contractors’ insurance

    Ask subcontractors for evidence of their own liability cover before they start on site.

Non-negligence cover. Some building contracts ask for cover for damage to neighbouring property that happens without anyone being negligent, such as from piling or vibration. Check whether your contract needs it.

Comparing

Checking Property Developers Quotes Side by Side

Four areas decide whether a policy suits the project: the cover, liability, the period, and cost terms. The price is only one of them.

The cover

  • Contract works to the full value
  • The existing structure, if any
  • Plant, tools and materials

Liability

  • Public liability limit
  • Employers’ liability
  • Non-negligence cover if needed

The period

  • Single project or annual
  • Extending if the build overruns
  • Cover for completed units

Cost terms

  • The excess
  • Higher excesses for theft or water
  • Paying monthly or upfront

Read the policy against the building contract. The insurance the contract asks for is what the policy needs to deliver. Unfamiliar terms are explained in our plain English jargon guide.

Cutting costs

How to Reduce the Cost of Property Developers Insurance

The levers are an accurate description of the project, good site security, the right sums insured, and the excess. We publish no savings figures.

Describe the project fully

Drawings and a programme help an insurer rate it fairly.

Secure the site

Hoarding, lighting and locked storage can help the terms.

Get the sums insured right

Too high wastes premium; too low invites a reduced claim.

Use insured contractors

Check their cover before they start.

Consider annual cover

It can suit a developer with a steady pipeline of sites.

Choose the excess deliberately

A higher excess is a lever, worth using only at a level you could absorb.

FAQs

Property Developers Insurance FAQs

Answers on contract works, liability, building contracts and sums insured.

What is property developers insurance?

Project cover for a developer building, converting or refurbishing property to sell or let. It insures the works as they progress, any existing structure, and liability on site, with plant and completed buildings on many policies.

What is contract works cover?

Cover for the works under construction, the materials on site and the work in progress, against events such as fire, storm, flood, theft and accidental damage. It is also called contractors’ all risks.

How much should I insure the works for?

The completed value of the works, not the cost at the start. The value rises as materials and labour go in, so review the figure as the project grows, as under-insurance can reduce a claim.

Does it cover the existing building on a conversion?

Many policies can, as a separate section for the existing structure at its rebuild figure. A standard buildings policy can restrict cover once major works start, so check how the existing building is insured.

Who insures the works, me or the contractor?

The building contract can set this out. Some contracts put the duty on the developer, some on the contractor, and some ask for joint names. Match the policy to what the contract says.

Do I need employers’ liability?

Where you take on site staff or labour-only subcontractors, employers’ liability is normally needed, so check it is on the policy. Subcontractors with their own business and cover may be treated differently, so tell the insurer who works on site.

Is public liability included?

Many developer policies include it as a core section, covering injury or damage to the public, neighbours and nearby property. Check that the limit suits the site and anything the building contract asks for.

What is non-negligence cover?

Cover for damage to neighbouring property that happens without anyone being negligent, such as subsidence from piling or vibration. Some building contracts ask for it, so check whether yours does.

Are plant and tools covered?

Some policies include owned and hired plant, tools and site huts, and others offer them as extras. Hired-in plant can carry continuing hire charges after a loss, which some policies also cover.

Can I get annual cover for several projects?

Yes. A developer with a steady pipeline of sites can arrange an annual policy with a maximum contract value, instead of separate cover for each project. Single project cover can suit an occasional developer.

What about a finished building that has not sold?

Some developer policies carry cover on for completed units until they are sold or let, often with conditions for empty property such as regular inspections. Check how long that cover lasts.

Does it cover faulty workmanship?

Putting right the faulty work itself is usually excluded, but damage it causes to other parts of the works can be covered. Contractors and warranties can also play a part, so check the policy and the contract.

What if the build overruns?

Tell the insurer before the cover ends. Many policies can be extended, but a lapse while work continues can leave the site unprotected, so build some slack into the period.

Does timber frame construction affect cover?

It can. A timber frame under construction is a higher fire risk, so insurers can set extra site security and fire conditions. Describe the construction method when you ask for quotes.

What happens when the project finishes?

Tell the insurer at practical completion. Completed units can move to cover for unsold property, and once they are let or occupied, standard property or landlord cover takes over.

How do I compare property developers quotes?

Look beyond the price to the contract works value, the existing structure, liability limits, non-negligence, plant, the period, cover for completed units and the excess you would pay.
