Everything you need to know about buildings insurance uk in the UK.
Buildings insurance covers the cost of repairing or rebuilding the physical structure of your home if it is damaged or destroyed. The policy typically protects the walls, roof, floors, ceilings, doors, windows, fitted kitchens, built-in wardrobes, bathroom suites, permanent fixtures and fittings, and outbuildings such as garages and garden sheds.
It also usually covers boundary walls, fences, gates, driveways, paths and underground pipes and cables that serve the property. In the event of a total loss—for example, after a severe fire—buildings insurance pays the rebuild cost, which is the amount needed to reconstruct the property from scratch, including demolition, site clearance, architects’ fees and compliance with current building regulations.
Buildings insurance is not a legal requirement for homeowners, but virtually all mortgage lenders insist you hold a policy for the duration of the loan. Even if you own your home outright, going without cover is a significant financial risk.
A standard buildings insurance policy covers damage caused by a defined list of insured perils. These typically include fire, lightning, explosion, storm, flood, escape of water, subsidence, heave, landslip, theft, attempted theft, vandalism, impact by vehicles or aircraft, and falling trees or aerials.
Many policies also cover accidental damage to underground pipes and cables, fixed glass and sanitary ware. You can often add wider accidental damage cover as an optional extra, which protects against events like accidentally drilling through a water pipe or putting your foot through a ceiling.
Buildings insurance does not cover general wear and tear, gradual deterioration, or damage caused by a lack of maintenance. If your roof leaks because tiles have become worn over many years, the insurer will not pay for a replacement. Similarly, damp caused by poor ventilation is unlikely to be covered.
Most policies exclude damage that occurs during building works unless you have notified the insurer in advance. War, terrorism (although Flood Re and Pool Re schemes do cover some of these), and damage caused by domestic pets are also common exclusions.
Always read the policy wording carefully. Pay particular attention to any endorsements (special conditions) that may apply—for example, a subsidence exclusion if the property has a history of ground movement.
The average UK buildings insurance premium is around £120 to £200 per year, but costs vary widely depending on the property’s rebuild value, location, construction type, age and claims history. Homes in areas prone to flooding or subsidence, or those with non-standard construction (such as flat roofs, timber frames or thatched roofs), tend to attract higher premiums.
To keep costs down, consider increasing your voluntary excess—the amount you agree to pay towards any claim. An excess of £250 to £500 is common. Installing security measures like burglar alarms and British Standard locks can also reduce premiums.
💡 The rebuild cost of your home is usually much lower than its market value. You can find an estimate on the Buildings Cost Information Service (BCIS) calculator provided by RICS, or ask a chartered surveyor for a formal rebuild valuation. Getting this figure right avoids both over-insuring and under-insuring.
One of the most common mistakes homeowners make is insuring their property for its market value rather than its rebuild cost. The market value includes the land, which does not need to be insured. The rebuild cost is the amount it would take to reconstruct the building from nothing, including demolition costs, professional fees and meeting current building regulations.
Under-insuring can be just as problematic. If the sum insured is significantly less than the true rebuild cost, the insurer may apply the average clause and reduce any claim payout proportionally. For example, if you insure for £200,000 but the true rebuild cost is £400,000, the insurer could pay only 50% of any claim.
You need buildings insurance in place from the date you exchange contracts on a property purchase—not completion. At the point of exchange, the buyer assumes risk for the building in most standard contracts. Your mortgage lender will require evidence of cover before they release funds.
If you are a leasehold flat owner, buildings insurance is usually arranged by the freeholder or managing agent, and the cost is included in your service charge. Check your lease to confirm this, and make sure the policy provides adequate cover.
⚠️ If you renovate your property or add an extension, remember to update your buildings insurance sum insured. Failing to do so could leave you under-insured and at risk of a reduced payout if you need to make a claim.
If you need to make a buildings insurance claim, contact your insurer as soon as possible. Take photographs of the damage and keep any damaged items as evidence. For emergencies such as burst pipes, you can arrange temporary repairs to prevent further damage—keep receipts for these costs as they are usually reimbursable.
The insurer will typically send a loss adjuster to assess larger claims. They will determine the cause and extent of damage and agree the repair scope. For subsidence claims, the process can be lengthy—often 12 months or more—as monitoring may be required before permanent repairs can begin.
