What Is Buy-to-Let Insurance and What Does It Cover?

Is buy-to-let insurance the same as landlord insurance?

Yes. Buy-to-let insurance, landlord insurance and let property insurance are three names for the same contract, and no UK insurer sells a separate buy-to-let product with different cover inside it.

Why the same policy has four different names

Brokers name the product after the customer they want to reach. Mortgage brokers say buy-to-let because that is what the loan is called, while underwriters write let property on the schedule.

Where the wording genuinely does change

The name on the marketing page is cosmetic, but the occupancy you declare is not. A let property policy is rated on who lives there, how long the tenancy runs and whether the property stands empty between lets.

Declare a professional couple and get students, and the insurer can treat the risk as misrepresented. That is the only difference that ever costs a landlord a claim.

What does a buy-to-let policy cover?

Buildings cover and property owners’ liability form the core of every policy. Contents, loss of rent, rent guarantee, accidental damage and legal expenses are bolted on according to how you let the property.

The two sections you should never drop

Buildings cover pays to rebuild or repair the structure, the roof, the fitted kitchen, the bathroom and the boiler. Landlord buildings insurance is priced on rebuild cost, and it is the section your lender cares about.

Property owners’ liability pays compensation and legal costs if a tenant or visitor is injured because of a defect at the property. Limits of £1m to £5m are standard and the section usually costs very little.

Landlord contents cover insures only the furniture and white goods you supply. Unfurnished lets rarely need more than carpets, curtains and a cooker insured.

The optional sections and what they add

• Rent guarantee matters more since possession became slower, and it pays while you wait for a court date.
• Accidental damage cover picks up the drilled pipe and the cracked shower tray that named perils leave out.
• Legal expenses cover funds a solicitor when a possession claim is defended.
• Landlord home emergency cover gets a heating engineer out on a Sunday without an argument about who pays.

Which perils are insured as standard

Fire, explosion, storm, flood, lightning, subsidence, escape of water, theft, vandalism and impact damage are the named perils on every buy-to-let policy. Subsidence normally carries its own excess of £1,000 or more.

Escape of water is the claim you are most likely to make. The NRLA reports that 28.63% of claims in 2024 came from water escaping, which is almost one in three.

Why will your home insurance not cover a let property?

Home insurance is written for owner-occupied houses and excludes property that is let or sublet. Letting without telling the insurer is a misrepresentation, and it can void the whole policy rather than just the one claim.

What happens when you claim

The first question a loss adjuster asks is who was living there. If the answer is a tenant, the claim is declined and the policy is usually voided from inception, which the ABI treats as a straight failure to disclose a material fact.

A voided policy then has to be declared on every insurance application you make afterwards, motor included. Our guide to what can invalidate home insurance covers the other declarations landlords forget.

Switching cover before the tenant moves in

Tell your home insurer the day you decide to let, not the day the tenancy starts. Most will cancel cleanly and refund the unused premium.

Cover should be live from the moment the keys leave your hands. An empty property waiting for a first tenant is already outside the home policy.

What does your buy-to-let mortgage lender require?

Every buy-to-let lender makes buildings insurance for the full rebuild cost a condition of the loan, with its interest noted on the policy. Nothing else is compulsory, though liability cover is nearly always sensible.

The four conditions lenders impose

• Buildings cover for the full rebuilding cost, not the price you paid.
• The lender’s interest noted on the schedule so it hears about any lapse.
• Cover live at exchange on a purchase, or at completion on a remortgage, which is the wording Accord and most high street lenders use.
• Continuous cover afterwards, or the lender can insure the property itself and bill you for it.

The insurer also has to know the property is let. A lender will not accept a home insurance schedule in place of a landlord one.

Rebuild cost is not market value

Rebuild cost is what it would take to clear the site and reconstruct the building. It is usually well below the sale price, and landlord buildings insurance explains how to get the figure from a survey or the BCIS calculator.

The ABI and BCIS House Rebuilding Cost Index put the rise in rebuilding costs at 5.9% in the year to the first quarter of 2026. A sum insured you set in 2023 is already short.

Underinsurance is punished proportionally. Insure a £200,000 rebuild for £100,000 and the insurer can settle a £20,000 escape of water claim at £10,000.

How much does buy-to-let insurance cost in 2026?

The median UK landlord policy costs £284.75 a year, according to Alan Boswell Group figures published on 31 March 2026. Most single-let houses fall between £150 and £400, and flats in converted blocks cost roughly double that.

What you pay by property and tenant type

Insurance Premium Tax and your tax return

Insurance Premium Tax is charged at the 12% standard rate on landlord policies and is already inside the price you are quoted. The whole premium is an allowable expense against rental income, which HMRC treats the same way as letting agent fees.

Keep the schedule and the receipt with your records for the tax year. A £300 premium at the higher rate of income tax costs you nearer £180 after relief.

How has the renters’ rights act changed what you need?

Since 1 May 2026 there is no Section 21 and no assured shorthold tenancy, so getting a property back takes longer and costs more. Rent guarantee and legal expenses cover have gone from optional extras to the sections that decide whether a bad tenancy bankrupts the year.

Periodic tenancies and old policy wording

Every tenancy is now a periodic assured tenancy under the Renters’ Rights Act, and possession runs through the Section 8 grounds. Some insurers still print assured shorthold tenancy in their rent guarantee conditions.

Ask your broker to confirm the wording has been updated before you rely on it. An eligibility condition that refers to a tenancy type that no longer exists is worth querying in writing.

Why the arrears maths changed

The mandatory arrears ground now needs three months of unpaid rent rather than two, with four weeks’ notice on top. On a £1,200 a month tenancy that is £3,600 gone before you can even serve notice.

Add a court listing and you are realistically six to nine months out of pocket. Rent guarantee at £100 to £300 a year pays for itself in a single claim.

Does owning through a limited company change your cover?

The cover is identical, but the policyholder must be the company rather than you. That one change also pushes the property outside the Flood Re scheme.

Whose name goes on the policy

Hamptons research published in February 2026 found 66,587 buy-to-let companies were set up in 2025, taking the total on the Companies House register to 443,272. Around three-quarters of new buy-to-let purchases now go through a company.

If the title is in the company name, the policy has to be too, or the company has no insurable interest in the building. Landlords holding several company properties usually move to a multi-property policy with one renewal date.

The flood re problem for company landlords

The Flood Re scheme requires the policy to be held in the name of one or more individuals, so a property owned through a limited company cannot use it at all.

Personally owned buy-to-lets do qualify, provided the property was built before 1 January 2009, sits in council tax bands A to H and is a single unit or a building of no more than three flats. In a flood postcode that is the difference between a £400 premium and a £2,000 one.

What is not covered by a buy-to-let policy?

Wear and tear, poor maintenance, your tenant’s own belongings and long void periods are the four exclusions behind most declined claims. None of them is buried in the small print, and all four are avoidable.

The exclusions that catch landlords out

Void periods are the common trap

Most policies cut back to fire, lightning and explosion once the property has stood empty for 30 to 45 days. A longer refurbishment or a slow reletting needs an unoccupied property policy or an unoccupancy extension.

Insurers set conditions with it, usually weekly inspections and the water drained down in winter. Meet them and cover holds, ignore them and it does not.

Which buy-to-let policy fits your property?

Standard buy-to-let cover works for a single household in a whole house or flat. Shared houses, blocks, short lets and benefit tenancies all sit outside it and need a policy written for that occupancy.

Matching the Policy to the Let

Three or more tenants from separate households makes the property an HMO, and a standard policy will not respond. HMO insurance prices the extra kitchens, locks and fire doors properly.

If you own the freehold of a converted house you insure the whole structure through a block of flats policy, not four separate buy-to-let policies.

Short-stay letting needs Airbnb cover because guests are not tenants, and letting to housing benefit claimants is written on a DSS landlord policy.

Comparing quotes without getting stung

Compare the excess before the premium. A policy £40 cheaper with a £750 escape of water excess is a false economy on a flat with old pipework.

Check the unoccupancy limit, the malicious damage position and whether loss of rent is included or extra. Those three lines separate two quotes that look identical.
