Allowable Expenses for UK Landlords

A practical guide to rental-property expenses, repairs versus improvements, residential finance-cost relief, replacement items, records, and the property allowance.

Day-to-day costs of letting can be deductible when incurred wholly for the property business.
Repairs and improvements are treated differently.
Individual residential landlords do not deduct mortgage interest in the same way as companies.
The £1,000 property allowance is an alternative to claiming actual expenses for qualifying income.

Start with rental profit, not rent received

Tax is generally based on rental profit: property income minus allowable day-to-day expenses, subject to specific adjustments. Keep each UK property business separate from overseas property and from company-owned property where the rules differ.

The first question is what the cost was for. The second is whether it was revenue or capital. The third is whether a restriction, allowance, or special relief changes the treatment.

Common rental expense categories

The following are common starting points for a residential property business. The specific facts and ownership structure remain important.

CategoryCommon examplesWatch for
Management and professionalLetting-agent fees, accountancy and qualifying legal fees for short leasesPurchase, sale, financing and long-lease legal costs may be capital

Finance costsResidential mortgage interest and related finance costsIndividuals normally receive a basic-rate tax reduction rather than an expense deduction

Repairs versus improvements

A repair restores an asset to its previous condition, allowing for modern equivalents. An improvement creates something better, extends useful life beyond repair, adds new space, or changes the character of the asset. Repair costs can be revenue expenses; improvements are normally capital and may be relevant when the property is sold.

Replacing a broken single-glazed window with the modern standard double-glazed equivalent may still be a repair. Adding an extension, converting a loft, or substantially upgrading beyond the nearest modern equivalent is more likely capital. Document before-and-after condition, specifications, and the reason for the work.

Important: Work completed immediately after buying a property can be capital if the property was not usable and the purchase price reflected that condition, even if the invoice says “repairs”.

Residential property finance costs

An individual landlord paying Income Tax does not generally deduct residential property finance costs from rental profit in the same way as an ordinary expense. Instead, qualifying finance costs normally feed into a basic-rate tax reduction, subject to detailed limits.

A company paying Corporation Tax can generally claim qualifying interest on property loans under company rules. Ownership structure, refinancing, mixed-purpose borrowing, and the amount originally invested can affect the answer.

Replacement of domestic items

Relief may be available when replacing domestic items supplied for tenants, such as beds, sofas, curtains, carpets, fridges, crockery, and cutlery. The old item must no longer be available for use, and the replacement must be for the tenant’s use in the property.

Relief is normally limited to the cost of an equivalent replacement plus qualifying disposal costs, less proceeds from the old item. Any element that represents an upgrade can be restricted. The initial purchase of furniture for a newly let property is not a replacement.

Property allowance or actual expenses

The property allowance can exempt or deduct up to £1,000 of qualifying property income. If gross qualifying property income is £1,000 or less, it may be fully covered, subject to exclusions. Where income is higher, partial relief may be claimed instead of actual expenses.

You generally cannot deduct actual expenses as well as the property allowance against the same income. Compare the allowance with evidenced expenses and check exclusions, particularly connected-party arrangements and company or partnership situations.

Records and Making Tax Digital

Keep tenancy agreements, rental statements, agent reports, invoices, receipts, mortgage statements, mileage or travel records, safety certificates, and calculations for shared or mixed costs. Track capital improvements separately from repairs so they are not lost when the property is sold.

Making Tax Digital for Income Tax is being phased in for qualifying gross self-employment and property income. Landlords in scope need compatible software, digital income and expense records, and quarterly updates, while retaining normal supporting evidence.

Frequently asked questions

Can a landlord claim the full mortgage payment?+

No. Repayment of loan capital is not an expense. Individual residential landlords normally receive a basic-rate tax reduction for qualifying finance costs rather than deducting interest directly from rental profit.

Can I claim improvements as repairs?+

Usually not. A repair restores condition; an improvement adds or upgrades beyond the nearest modern equivalent. Capital improvement costs may instead be relevant to Capital Gains Tax when the property is sold.

Can I use the property allowance and claim expenses?+

Generally not against the same qualifying income. The property allowance is normally used instead of actual expenses, so compare both methods and check the exclusions.
