Landlords pay tax on rental profit, not simply on the rent collected. Calculating that profit correctly means recording income and claiming costs that meet the property-business rules.
This guide explains common landlord allowable expenses, the difference between repairs and improvements, residential mortgage-interest restrictions and the £1,000 property allowance.
What makes a landlord expense allowable?
An expense is generally deductible from rental income when it is incurred wholly and exclusively for the property business, is revenue rather than capital in nature, and is not private expenditure.
Where a cost has both business and private use, only a clearly identifiable business proportion may be allowable. Keep invoices, receipts, bank records and an explanation of the property purpose.
Landlord expenses: what you can and cannot usually claim
| Expense | Typical treatment |
|---|---|
| Letting-agent and management fees | Normally deductible |
| Landlord insurance | Normally deductible |
| Repairs and maintenance | Deductible where revenue, not capital |
| Utilities and council tax paid by landlord | Normally deductible for the let period |
| Accountancy and property-business legal costs | May be deductible, subject to purpose |
| Replacement domestic items | Relief may apply when conditions are met |
| Residential mortgage interest | Restricted for individual landlords; basic-rate tax reduction may apply |
| Property purchase or extension | Capital, not a rental-income expense |
| Mortgage capital repayments | Not deductible from rental income |
| Private or personal costs | Not deductible; apportion mixed-use costs where appropriate |
Repairs and maintenance
Repairs that restore an existing asset to its previous condition are commonly allowable. Examples include fixing a leaking roof, repairing a boiler, replacing broken tiles, redecorating between tenancies and repairing damaged plumbing.
Using modern materials does not automatically turn a repair into an improvement. Replacing old single-glazed windows with the nearest modern equivalent may still be a repair where the work broadly restores the asset rather than substantially upgrading it.
However, the complete replacement of an asset or work that creates something new may be capital. The facts, condition at purchase and scale of the work matter.
Repairs vs capital improvements
Capital expenditure improves, extends or fundamentally changes the property. It is not deducted from rental income, although it may be relevant to Capital Gains Tax when the property is sold.
Typical capital costs include buying the property, building an extension, converting a loft into additional accommodation or installing a new feature that did not previously exist.
Initial repairs need particular care. If a property was bought in a dilapidated condition at a price reflecting that condition and could not be let until substantial work was completed, some costs may form part of the capital acquisition rather than a revenue repair.
Letting-agent and management fees
Fees paid for tenant finding, rent collection, inspections and day-to-day property management are normally allowable. Inventory, referencing and tenancy administration costs may also qualify.
If a fee relates to buying or selling the property rather than operating the rental business, it is usually capital instead.
Insurance, utilities and council tax
Landlord building and contents insurance, rent-guarantee cover and relevant public-liability insurance are commonly deductible.
Where the landlord pays gas, electricity, water, broadband or council tax under the tenancy arrangement, those costs can normally be claimed. Private periods and amounts recovered separately from tenants must be treated correctly.
Professional and legal fees
Accountancy fees for preparing rental accounts and tax returns are generally allowable to the extent they relate to the property business.
Legal fees for renewing a short tenancy, collecting rent or dealing with ordinary management issues may qualify. Fees connected with purchasing, selling, extending or significantly altering the property are usually capital.
Travel and mileage
Genuine business journeys to inspect, maintain or manage the property may be deductible. Keep the date, destination, purpose and cost of each trip.
Ordinary private travel is not allowable. A journey that combines business and personal purposes needs a reasonable, supportable allocation.
Replacement of domestic items relief
Relief may be available when a landlord replaces a domestic item provided for a tenant. Qualifying items can include moveable furniture, beds, sofas, carpets, curtains, fridges, washing machines, crockery and cutlery.
The relief is based on the cost of a like-for-like replacement or nearest modern equivalent, plus qualifying disposal and delivery costs, less any proceeds received for the old item.
The initial cost of furnishing a property is not covered by replacement relief because no old item is being replaced. Any element that represents a superior upgrade is also restricted.
Mortgage interest and finance costs
An individual landlord cannot deduct residential property finance costs from rental income in the same way as ordinary expenses. Instead, qualifying finance costs may produce a basic-rate tax reduction, normally calculated at 20%, subject to statutory limits.
The reduction is based on the lowest of relevant finance costs, property-business profit and adjusted total income above the Personal Allowance. Unused finance costs may be carried forward.
Finance costs can include mortgage interest, interest on loans used for the residential property business and certain related fees. Capital repayments are never an expense.
A limited company is subject to Corporation Tax rules and can generally deduct interest on property loans when the expense meets those rules. This difference does not automatically mean incorporation is best because transfer taxes, refinancing, extraction tax and administration must also be considered.
The £1,000 property allowance
Individuals can receive a property allowance of up to £1,000 each tax year. If gross property income is £1,000 or less, full relief may mean it does not need to be reported, subject to exceptions.
Where gross property income exceeds £1,000, a landlord may elect to deduct the £1,000 allowance instead of actual expenses. You cannot claim both against the same income.
Compare the allowance with actual allowable costs. A landlord with £4,000 of genuine expenses would normally be worse off choosing a £1,000 deduction.
The allowance has exclusions and can interact with residential finance-cost relief, connected-party income and other claims. Do not assume it is always available.
Advertising and tenant costs
Costs of advertising a property, using a letting platform, carrying out tenant referencing and preparing an inventory can normally be allowable where they relate to the rental business.
Refundable tenant deposits are not rental income when protected and held under the tenancy rules. Amounts retained for unpaid rent or damage require correct accounting.
Safety and compliance costs
Routine costs of meeting landlord obligations may qualify, including gas-safety checks, electrical inspections, energy-performance certificates, smoke alarms, licensing fees and ordinary compliance inspections.
If compliance work forms part of a large capital improvement, its treatment may follow that wider project. Separate invoices and clear descriptions help support the distinction.
Home-office, phone and administration
A reasonable proportion of phone, postage, stationery, software and home-office costs may be deductible where used for managing the properties.
Claims must reflect actual business use and should not include private consumption. Keep a simple calculation showing the basis used.
Expenses before the first tenant moves in
Some pre-letting revenue expenses may be allowable where they were incurred wholly and exclusively for the rental business and would have qualified if incurred after letting began.
Costs of acquiring the property, bringing an unlettable building into usable condition or making substantial improvements are more likely to be capital. The date the property business began and the nature of each cost should be reviewed.
Jointly owned rental property
Income and expenses must be allocated between the owners under the relevant ownership and tax rules. Married couples and civil partners living together are normally taxed on equal shares unless the conditions for a different beneficial split and declaration are met.
Each owner should retain records and report their correct share. The arrangement should match the legal and beneficial ownership rather than an informal year-end decision.
Rental losses
Allowable expenses can create a property-business loss. A UK property loss is usually carried forward against future profits from the same UK property business; it is not normally set against salary or unrelated income.
Finance-cost restrictions and the property allowance can alter the calculation, so a cash shortfall does not always equal the tax loss shown on the return.

Frequently asked questions
Can landlords claim mortgage payments?
Capital repayments are not allowable. Individual residential landlords may receive a basic-rate tax reduction for qualifying finance costs instead of deducting them from rent.
Can I claim a new kitchen?
A like-for-like replacement may be a repair, while a significant upgrade or reconfiguration may be partly or wholly capital. Review the complete project.
Can I claim furniture for a rental property?
Replacement domestic items relief may cover qualifying replacement furniture. The initial purchase is generally not covered by that relief.
Is the £1,000 property allowance automatic?
Full relief may apply where qualifying gross income does not exceed £1,000. Above that amount, choosing the allowance instead of actual expenses may require an election and is not always beneficial.
