Commercial Property Insurance UK

There’s no standard price because every building is different. A small retail unit in a low-risk area might cost a few hundred pounds a year. A large warehouse or multi-tenanted building in a flood zone could run into thousands.

The factors that drive the premium are the building’s size, age, construction type, location, flood and crime risk, the business type operating inside it, security and fire protection systems, claims history, and crucially, the rebuild cost. Getting that rebuild figure right is one of the most important things you can do.

• Small retail units may start from a few hundred pounds per year
• Large warehouses and industrial units cost significantly more
• Key factors are building size, age, construction, location, flood/crime risk, and business type
• Security systems, fire alarms, and sprinklers can reduce premiums
• Rebuild cost accuracy is critical, underestimating leads to reduced payouts
• Comparing specialist broker quotes is the best way to find competitive pricing

Most people assume it’s only the landlord’s problem. It’s not. Your lease almost certainly requires you to hold certain cover, and even if it doesn’t, you’re still liable for your own contents, stock, equipment, and any improvements you’ve made to the building.

If a fire destroys your stock and you’ve got no contents cover, that’s your loss entirely. If you’ve spent £20,000 fitting out the interior and a burst pipe ruins it, your landlord’s buildings policy won’t cover your fit-out.

• Tenants are usually responsible for insuring their own contents, stock, and equipment
• Lease agreements often require tenants to hold specific insurance cover
• Landlord’s buildings insurance does not cover tenant fit-outs or improvements
• Stock, inventory, and business equipment need separate contents cover
• Always check your lease for specific insurance obligations

This is the one thing I see people get wrong more than anything else. The rebuild cost is not the market value of your property. It’s the amount it would cost to completely demolish and rebuild from scratch, including materials, labour, architects’ fees, and current building regulations.

Under-insurance is the real danger. Insurers apply the average clause, so if your building costs £500,000 to rebuild but you’ve insured it for £250,000, any claim payout gets reduced by 50%. I’ve seen that destroy businesses. Get a professional RICS valuation every three to five years.

• Rebuild cost is the amount to demolish and completely reconstruct the building
• It is not the same as market value or purchase price
• Includes materials, labour, architects’ fees, and building regulation compliance
• Under-insuring triggers the average clause, reducing claim payouts proportionally
• A RICS rebuild valuation every three to five years ensures accuracy
• Getting this figure wrong is one of the most common and costly mistakes

A comprehensive policy covers damage from fire, flood, storm, lightning, explosion, subsidence, theft, vandalism, and impact. It also usually covers fixtures, fittings, plumbing, and electrics.

The extras are where it gets important. Business interruption pays lost income. Contents cover protects stock and equipment. Property owners’ liability covers injury claims. Loss of rent protects landlords. Not all of these are standard, some are add-ons.

• Building damage from fire, flood, storm, subsidence, theft, and vandalism
• Fixtures, fittings, plumbing, electrics, and permanent installations
• Business interruption covers lost income if premises are unusable
• Contents cover for stock, equipment, and furniture
• Property owners’ liability for injury claims on your premises
• Loss of rent for landlords if tenants can’t occupy the building
• Not all extras are standard, always check what’s included

Yes, and for landlords or investors with more than one building, a portfolio policy is almost always the smarter option. One renewal date, one broker, one claims contact. The admin savings alone are worth it.

I’ve worked with landlords who had six different policies with six different insurers. Switching to a single portfolio policy saved them money and about three days of admin a year.

• Multi-property and portfolio policies are available for landlords and investors
• One renewal date, one broker, one claims contact
• Insurers often offer discounts for multiple properties on one policy
• Reduces admin significantly compared to separate policies
• Can include a mix of property types, offices, retail, industrial, residential lets

Many policies include flood cover, but if your property sits in a high-risk area, standard insurers may exclude it or charge a significant loading. Flood risk is assessed by postcode.

If you’re in a flood-prone location, a specialist broker can access insurers who still write flood risk. Either way, declare the risk accurately and make sure the policy explicitly includes it.

• Many comprehensive policies include flood cover
• High-risk flood areas may face exclusions or higher premiums
• Flood risk is assessed by postcode
• Specialist brokers can access insurers who write high-risk flood properties
• Always declare flood risk accurately and confirm cover is explicitly included

Business interruption insurance covers the income you lose when your premises become unusable after an insured event. Without it, you’ve got a building being repaired but no revenue coming in, and you still have wages, rent, loan repayments, and overheads to cover.

Honestly, this is the add-on I recommend most strongly. Buildings can be rebuilt. But if your cash flow dries up for six months, the business itself might not survive.

• Covers lost income when premises become unusable after an insured event
• Pays for ongoing costs like wages, rent, loan repayments, and overheads
• Available as an add-on to your commercial property insurance
• Indemnity periods of 12, 24, or 36 months are common
• One of the most important add-ons for any business that depends on its premises
• Without it, a major incident can destroy the business even if the building is insured

Security is the biggest lever. Burglar alarms, CCTV, fire alarms, sprinkler systems, secure locks, these all reduce risk and premium. Insurers want to see you’ve taken reasonable steps to protect the property.

Beyond security, make sure your rebuild cost is accurate, maintain the building well, and compare quotes from specialist brokers every year. Multiple properties on a portfolio policy often get a better rate.

• Install burglar alarms, CCTV, fire alarms, and sprinkler systems
• Ensure rebuild cost is accurate, not inflated or underestimated
• Maintain the building, fix issues before they become claims
• Compare specialist broker quotes every year at renewal
• Multi-property portfolio policies often deliver better rates
• Increase voluntary excess if comfortable carrying more risk
• Pay annually to avoid monthly interest charges

Standard policies usually don’t, and this catches landlords out between tenancies. Most insurers limit cover or void it entirely if a property is unoccupied for more than 30 to 45 days. The risks go up sharply, vandalism, squatters, undetected water damage, fire.

If you’ve got a void period coming, tell your insurer immediately. You may need a specialist unoccupied property policy until the building is occupied again.

• Standard policies usually exclude or limit cover for unoccupied buildings
• Most insurers define unoccupied as empty for 30 to 45 consecutive days
• Risks increase sharply, vandalism, squatters, water damage, fire
• Specialist unoccupied property insurance is available for void periods
• Failing to declare vacancy can result in claims being rejected
• Always notify your insurer immediately if a property becomes unoccupied

Buildings insurance covers the physical structure, walls, roof, floors, fitted kitchens, plumbing, electrics, permanent fixtures. Contents insurance covers everything inside that isn’t permanently attached, stock, furniture, computers, equipment.

Most businesses need both. A landlord insures the building, a tenant insures the contents, an owner-occupier needs the lot. Getting this split wrong means gaps, and I’ve seen claims fail because the wrong party assumed the other had it covered.

• Buildings insurance covers the physical structure and permanent fixtures
• Contents insurance covers stock, furniture, equipment, and non-permanent items
• Landlords typically insure buildings, tenants insure contents
• Owner-occupiers need both buildings and contents cover
• Getting the split wrong creates gaps that lead to rejected claims

Yes. Insurers treat restaurants, takeaways, and food businesses as higher risk because of commercial cooking equipment, deep fat fryers, gas supplies, and the fire exposure that comes with all of that.

A standard commercial property policy might not cover the specific risks. You may need additional cover for refrigeration breakdown, public liability for customer injury claims, and stock spoilage.

• Restaurants and food businesses are classed as higher risk by insurers
• Commercial cooking equipment and fire exposure drive higher premiums
• Refrigeration breakdown cover protects against stock loss
• Public liability is essential for customer-facing food businesses
• Stock spoilage cover is an important add-on
• A broker with hospitality sector experience gets better terms

Yes, but expect to pay more. Flat roofs are more prone to water ingress, pooling, and storm damage. Insurers know this and price accordingly.

You may need to provide evidence of regular maintenance, a recent roof survey, or confirmation of replacement within a certain timeframe. A well-maintained flat roof with documentation gets better terms than one that hasn’t been touched in 15 years.

• Flat roof buildings can be insured but attract higher premiums
• Increased risk of water ingress, pooling, and storm damage
• Insurers may request evidence of regular maintenance or a recent roof survey
• Recently replaced or repaired flat roofs get better terms
• Documentation of maintenance history helps at quote stage

Some policies include malicious or accidental damage by tenants, but many require it as an optional extra. If you’re a landlord, this is worth paying attention to.

Check whether the policy covers malicious damage, accidental damage, and damage during eviction. Some insurers also offer rent guarantee insurance to protect income if a tenant stops paying.

• Some policies include tenant damage, others require it as an optional add-on
• Check cover for malicious damage, accidental damage, and damage during eviction
• Tenant damage can be expensive for landlords without the right cover
• Rent guarantee insurance is a separate product protecting against unpaid rent
• Landlords should always check tenant damage terms before purchasing

Pretty much anything with four walls and a business operating inside it. Offices, shops, restaurants, cafes, pubs, salons, warehouses, factories, industrial units, surgeries, hotels, care homes, and mixed-use buildings.

• Offices, shops, restaurants, warehouses, factories, and industrial units
• Salons, hotels, care homes, surgeries, and pubs
• Mixed-use buildings with commercial and residential elements
• Landlord portfolios with multiple commercial properties
