Landlord insurance: cover, cost and tax treatment
Standard home insurance does not cover a let property. Getting the cover right is cheaper than discovering a gap after a claim.

Overview
Landlord insurance bundles buildings cover with property owners liability and usually offers optional contents, loss of rent, rent guarantee, home emergency and legal expenses cover. Letting a property without telling your insurer typically voids a standard policy. Premiums are an allowable expense against rental income, and the cover you choose should reflect the type of let, the tenant profile and how quickly you could fund a large repair yourself.
Why it matters
Underinsurance and undisclosed lettings are the two failures that turn a manageable incident into a portfolio level loss.
Legal requirements
- Buildings insurance is normally required by a mortgage lender.
- Property owners liability protects against injury claims by tenants and visitors.
- Insurers must be told the property is let and told about the tenant type.
- Premiums are deductible as a revenue expense against rental profit.
Common mistakes
- Keeping a residential policy after letting the property out.
- Insuring for market value rather than rebuild cost.
- Not disclosing student, HMO or benefit claimant lets where the insurer asks.
- Assuming loss of rent cover is the same as rent guarantee cover.
Practical guidance
- Insure for the rebuild cost from a survey or an insurer calculator, not the sale price.
- Check the unoccupancy clause, which often limits cover after thirty or sixty days empty.
- Consider rent guarantee cover where a void or arrears would strain cash flow.
- Review annually rather than auto renewing, since landlord premiums move a lot.
Loss of rent compared with rent guarantee
Loss of rent cover pays when the property is uninhabitable after an insured event such as a fire or a flood. Rent guarantee cover pays when a tenant simply stops paying, and it usually requires referencing to a stated standard plus prompt notification of arrears. The two solve different problems and landlords often assume they have one when they hold the other. Read the notification deadlines, because late reporting is the main reason rent guarantee claims fail.
Keeping cover valid
Insurers expect the property to be maintained, compliant and inspected. A missing gas safety record, an expired electrical report or evidence that a known defect was ignored can all be used to resist a claim. This is where a compliance record helps twice, once for the law and once for the insurer. Store certificates, inspection reports and repair correspondence together so a claim can be evidenced within days rather than weeks.
Frequently asked questions
Is landlord insurance a legal requirement?
Buildings insurance is usually a mortgage condition rather than a statutory duty, but property owners liability is strongly advisable and often required by licensing schemes.
Can I claim the premium against tax?
Yes, insurance for the let property is an allowable revenue expense.
Who insures tenant belongings?
The tenant. Your contents cover applies to items you provide, so tell tenants to arrange their own contents insurance.
