| Buildings insurance covers the physical structure of your home — walls, roof, floors, windows, and fixed fittings — against damage from fire, flooding, subsidence, storms, and other covered events. It's not a legal requirement, but virtually every mortgage lender makes it a condition of the loan. The ABI confirmed that home insurance premiums rose 8-15% in 2025 driven by severe weather claims and rising build costs. This guide covers exactly what's covered, what isn't, how much it costs, and how to get the best deal in 2026. | ||||||||||||||||||||||||||||||||||||

Rebuild Cost vs Market Value — The Most Important Distinction | ||||||||||||||||||||||||||||||||||||
| Buildings insurance must be set to the rebuild cost of your property — not the market value. The rebuild cost is how much it would cost to demolish and completely rebuild your home from scratch, including labour, materials, and professional fees. In most parts of the UK, rebuild cost is lower than market value (especially in London and the South East, where land value dominates). In some northern regions, rebuild costs may be similar to market value. Underinsuring your rebuild cost — setting the sum insured too low — is called 'average', and it means the insurer can reduce any claim proportionally. If you're insured for 50% of the true rebuild cost, you may receive only 50% of any claim payment. Use the ABI's online rebuild cost calculator or commission a RICS professional to get an accurate figure. | ||||||||||||||||||||||||||||||||||||

Do Flat Owners Need Buildings Insurance UK? | ||||||||||||||||||||||||||||||||||||
| If you own a leasehold flat, the freeholder is typically responsible for arranging buildings insurance for the entire block, which you contribute to through your service charge. You should check: whether the freeholder's buildings policy is adequate; the sum insured for the block; and any gaps that may affect your unit. Flat owners should always arrange their own contents insurance separately — covering their furniture, belongings, and any internal fittings they own. When buying a leasehold flat, ask your solicitor to obtain a copy of the current buildings insurance policy and confirm that the building is insured to an adequate rebuild value. | ||||||||||||||||||||||||||||||||||||
Frequently Asked QuestionsIs buildings insurance a legal requirement UK? Buildings insurance is not a UK legal requirement — but it is almost always a condition of your mortgage. If you have a mortgage, your lender will require buildings insurance to be in force from the moment you exchange contracts. If you own your home outright (mortgage-free), you're not legally required to have buildings insurance, but not having it would be financially reckless — the cost of rebuilding after a major fire without insurance would be catastrophic. When must buildings insurance start UK? Buildings insurance must be in place from the point of exchange of contracts — not completion. Once contracts are exchanged, you are legally committed to the purchase, and any damage to the property between exchange and completion is your financial responsibility. Most buyers arrange buildings insurance to start on their exchange date. Your solicitor will confirm the exchange date in advance. How is buildings insurance calculated UK? Premiums are based on: the rebuild cost of the property (not market value); construction type (standard brick/tile vs non-standard); location (flood risk, crime rate, subsidence risk); property age; your claims history; and chosen cover level including any add-ons. Get an accurate rebuild cost estimate from the ABI rebuild calculator or a RICS surveyor. Does buildings insurance cover damp UK? Generally no. Damp is classified as gradual deterioration (wear and tear) and excluded. The exception: damp caused by a sudden, unforeseen event — like a burst pipe — would typically be covered as 'escape of water'. Gradual penetrating damp through brickwork, rising damp, or condensation are maintenance issues that are the homeowner's responsibility. | ||||||||||||||||||||||||||||||||||||
