Do I need buildings and contents insurance?

If you own your home with a mortgage, buildings insurance is almost always a mortgage condition — your lender requires it. Contents insurance is optional but strongly recommended for most homeowners. If you rent, your landlord is responsible for buildings insurance (covering the structure), but you need your own contents insurance to cover your personal belongings — landlords' buildings insurance does not cover tenants' possessions. Leaseholders (flats) typically need contents insurance only, as the freeholder's insurance covers the building.

How much contents insurance do I need?

Contents insurance should cover the full replacement cost of everything in your home — not the second-hand value. A common mistake is under-insuring by estimating too low. Recommended approach: go room by room and list what you'd need to replace everything from scratch. Include: furniture, white goods, electronics, clothing, jewellery, sports equipment, and garden items. UK insurers estimate the average household needs £35,000–£50,000 of contents cover. Under-insuring can result in your claim being reduced proportionally (called average clause).

What is not covered by home insurance?

Standard home insurance typically excludes: general wear and tear and gradual deterioration, storm damage to gates, fences, and hedges (usually excluded), frost/freezing damage to exterior pipes (often excluded), subsidence in some high-risk areas (may require specialist cover), business equipment used for work purposes above a low limit, and valuables above the single-item limit (typically £1,000–£2,000 — expensive jewellery, art, or watches may need to be separately listed). Always read the exclusions section carefully.

Buildings vs Contents Insurance

UK home insurance is divided into two distinct products, often sold together as a combined policy:

Covers the structure

Buildings Insurance

Covers the physical structure of your home — walls, roof, floors, windows, fitted kitchens and bathrooms, permanent fixtures, and external structures (garages, outbuildings). Required by most mortgage lenders. Covers: fire, flood, storm damage, subsidence, escape of water, impact (e.g. vehicle hitting the building). Does NOT cover: contents/possessions, general wear and tear, deliberate damage by you.

Covers possessions

Contents Insurance

Covers everything inside your home that would "fall out" if you turned it upside down — furniture, electronics, clothing, appliances, jewellery, and personal possessions. Covers: theft, fire, flood, accidental damage (on enhanced policies). Does NOT cover: the building itself, items left outside, or possessions above the single-item limit without being separately listed.

ℹ️ Renters need contents only

If you rent, your landlord's buildings insurance covers the structure — not your belongings. You need your own contents insurance. Renters' contents insurance is typically cheaper than homeowner cover (no building to insure) and can be arranged monthly. Don't assume your possessions are covered under the landlord's policy — they are not.

What Buildings Insurance Covers

Buildings insurance covers damage to the structure caused by specific listed perils. Standard cover in the UK includes:

Fire, explosion, smoke
Storm and flood (though some high-flood-risk properties may face exclusions or very high premiums)
Escape of water (burst pipes — one of the most common claims)
Subsidence (ground movement causing structural damage — check carefully, as some older policies or high-risk areas have limits)
Impact (vehicle hitting the house, falling trees or aerials)
Theft or attempted theft (damage to the building during a break-in)
Malicious damage by third parties

Rebuild value vs market value: Buildings insurance should be based on the rebuild cost — what it would cost to demolish and rebuild your property from scratch — not the market value. In many areas, particularly London, the market value is far higher than the rebuild cost. Over-insuring on rebuild value wastes money; under-insuring means claims may be proportionally reduced. Use the ABI's rebuild calculator (abi.org.uk) to estimate your rebuild cost.

How to Value Your Contents Correctly

Under-insurance is one of the biggest home insurance mistakes. If your contents are insured for £20,000 but the true replacement value is £40,000, an insurer can apply the "average clause" — reducing any claim proportionally. A £10,000 theft claim might only pay out £5,000.

Go room by room and estimate replacement cost (new for old) for:

Room	What to Include	Common Underestimate
Living room	Sofa, TV, sound system, furniture	Forgetting curtains, rugs, ornaments
Kitchen	White goods, crockery, small appliances	Forgetting fridge-freezer, dishwasher, microwave
Bedroom	Bed, wardrobe, clothing, jewellery	Under-valuing clothing and jewellery
Office	Laptop, PC, printer, books	Work equipment above limits, specialist equipment
Garden	Garden furniture, tools, bikes	Often excluded or severely limited outside

Most policies include a single-item limit (typically £1,000–£2,000). Items above this — jewellery, watches, cameras, musical instruments, expensive bicycles — should be listed separately (specified items) to ensure full cover. Failing to list high-value items often means claims for them are limited or refused.

How to Reduce Your Premium Without Losing Cover

Shop the whole market at renewal

Loyalty rarely pays in insurance — renewal quotes are typically higher than new customer rates. Use comparison sites (Compare the Market, GoCompare, MoneySuperMarket) every year. Switching provider on renewal is one of the fastest ways to cut your premium.

Increase your voluntary excess

Your excess is the amount you pay per claim. Increasing your voluntary excess (on top of the compulsory excess) reduces your premium. Only do this if you could genuinely afford the total excess if you needed to claim.

Improve home security

Approved locks (BS 3621), burglar alarms, and security lighting can reduce premiums — particularly for contents cover. Some insurers offer specific discounts for accredited security products. Tell your insurer about any improvements.

Pay annually, not monthly

Monthly payments effectively add 10–25% APR interest to your premium. Paying annually is almost always cheaper.

Don't over-insure

Insure for actual rebuild cost (not market value) and actual contents replacement cost (not a round number you picked). Both over-insuring and under-insuring are costly in different ways.

Frequently Asked Questions

Standard buildings and contents policies often don't include accidental damage — it's an optional add-on. Without it, a red wine spill on a carpet or a cracked TV screen isn't covered. Accidental damage cover adds £20–£50/year to most policies. It's worth adding for families with young children or if you have expensive items that are easily damaged. Some policies include it as standard — check before assuming.

Standard contents insurance typically covers personal possessions — but business equipment (work laptop, specialist tools, client materials) above a low limit (often £500–£1,000) may not be covered. If you work from home, tell your insurer and either extend your policy to cover business equipment or arrange separate business equipment cover. Some insurers also require notification if you have clients visiting the property — this may affect your public liability cover.

Escape of water refers to water damage caused by leaking or burst pipes, or leaking appliances (washing machine hose, dishwasher). It's one of the most common home insurance claims — often more expensive than burglary or fire damage. Standard buildings (and sometimes contents) insurance covers escape of water. It does NOT cover the actual repair of the pipe or appliance that leaked — just the resulting damage (ruined carpets, ceilings, walls, furniture). Trace and access cover (finding where the leak is, including breaking through walls) is a separate optional add-on.
