Landlord allowable expenses UK: what can you claim?
Landlord expenses reduce taxable property profit only when the tax rules allow them; they do not simply follow what reduced cash in the bank. Repairs can differ from improvements, mortgage interest has special treatment for individual residential landlords, and replacement furniture has its own conditions. This guide explains the main expense categories, evidence to retain, and how to build a property calculation that can be traced from rent received to the figure reported through Self Assessment.

Start with gross rent, not the agent payout
A property calculation starts with gross rental income. If a tenant pays £1,200 a month and the agent keeps £120 before transferring £1,080, preserve £1,200 as rent and £120 as the agent fee. Recording only the payout hides both turnover and a cost. Income can also include separate payments for parking, services, furniture, cleaning or utilities where they form part of the letting arrangement. Record arrears, refunds, deposits retained and insurance receipts according to their nature and accounting method rather than treating every bank credit as rent. For joint ownership, maintain the full-property records and a clear allocation to each owner based on the legal and tax position. Download agent statements regularly and reconcile them to the tenancy agreement and bank. The rental income tax calculator needs gross rent and expenses in separate fields for exactly this reason. A clean starting figure makes later decisions about repairs, finance costs and the property allowance much easier to explain.
The basic test for an allowable revenue expense
An expense normally needs to be incurred wholly and exclusively for the property rental business and be revenue rather than capital in nature. Typical revenue costs can include letting-agent fees, accountancy relating to the property business, landlord insurance, service charges, ground rent, council tax and utilities paid by the landlord, advertising, cleaning, gardening and routine maintenance. A payment is not deductible merely because a landlord considers it necessary or because it appears on an agent statement. Personal costs, capital improvements, the property purchase price and legal fees connected with acquisition are not ordinary rental expenses. Mixed costs require a reasonable allocation. If a landlord travels partly for a property inspection and partly for a holiday, the private element cannot simply disappear. Keep invoices, contracts and an explanation of purpose. The appropriate treatment may differ where the property is held by a company, is commercial, is overseas or has non-commercial terms, so identify the ownership and letting type before using a generic list.
Repairs versus capital improvements
A repair restores an asset to its previous function; an improvement creates or enhances something beyond that state. Replacing a broken boiler with a modern equivalent can remain a repair even if technology has advanced, while adding an extension, converting a loft or installing a feature that materially upgrades the property can be capital. The invoice label is not decisive. Consider the condition before the work, what was done and whether a separate asset or enduring improvement was created. A larger project may contain both repair and improvement elements, so ask the contractor for an itemised invoice and allocate on a supportable basis. Work needed immediately after buying a run-down property can be capital where the purchase price reflected its unusable condition. Capital expenditure may affect the eventual Capital Gains Tax computation rather than current rental profit, so retain the evidence even when it is not deductible now. Do not discard a rejected expense; reclassify and store it with the property acquisition or improvement history.
Maintenance, safety and service costs
Routine maintenance can include plumbing repairs, redecorating between tenants, fixing appliances supplied with the property, servicing heating, replacing damaged locks and maintaining gardens or communal areas where the landlord is responsible. Safety certificates, inspections and compliance costs can be relevant to the rental business. Letting-agent management charges, tenant-finding fees and inventory services may also be revenue costs. Service charges should be analysed because a statement can contain routine expenditure, reserve-fund contributions or major capital works. Keep the managing agent’s breakdown rather than claiming the total without review. If a tenant reimburses a cost, record the income and expense consistently. Fines and penalties for breaking the law are not made allowable because they relate to a property. The landlord should also distinguish actual business expenditure from a deposit held on behalf of a tenant. An expense schedule with date, supplier, property, category, description, amount and evidence link makes these distinctions visible before the return is prepared.
Replacement domestic items relief
For qualifying residential lettings, replacement domestic items relief can apply when an old domestic item provided for a tenant is replaced. Items can include furniture, furnishings, household appliances and kitchenware. The relief is based on the cost of an equivalent replacement, plus relevant disposal or acquisition incidental costs, less proceeds from disposing of the old item. The additional cost of a genuine upgrade is not automatically relieved. If a basic sofa is replaced with a substantially superior model, identify the equivalent replacement cost rather than claiming the full premium without analysis. The initial purchase of an item for a newly furnished property is not the same as replacing an existing item. Keep the old item details, purchase invoice, disposal evidence and an explanation of any upgrade. The rules do not apply identically to every accommodation type or capital-allowance case. Do not use a generic “furniture” percentage; apply the actual conditions and retain a replacement-by-replacement schedule.
Mortgage interest and residential finance costs
An individual landlord of residential property does not normally deduct mortgage interest from rental income in the same way as agent fees or repairs. Since 6 April 2020, qualifying residential finance costs are generally considered through a basic-rate tax reduction, subject to detailed limits. Capital repayments are not an expense: they reduce the loan balance. This treatment can make taxable property profit look higher than the cash left after mortgage payments, especially for a higher-rate taxpayer. Keep annual lender statements separating interest, fees and capital. Do not enter the full monthly mortgage payment in the expense field of a simple calculator. Companies and some non-residential property businesses can have different finance-cost treatment, so ownership matters. If refinancing covers private spending or more than the property-business capital, interest allocation can become complex. Use a landlord or buy-to-let tool that states its finance-cost assumptions, and obtain advice where borrowing, ownership or use changed during the year.
Worked example: repair, improvement and finance cost
Nadia receives £15,600 gross rent. The letting agent deducts £1,560, landlord insurance is £260, a plumber repairs a leak for £480 and a worn washing machine is replaced with an equivalent model for £420 after £20 disposal proceeds. She also spends £7,000 adding a new conservatory and pays £4,800 mortgage interest plus capital repayments. Her revenue schedule includes the agent fee, insurance and leak repair. She reviews replacement domestic items relief for the net equivalent washing-machine cost. The conservatory is recorded as capital improvement evidence, not an ordinary rental expense. The capital mortgage repayment is excluded, while qualifying interest is taken to the separate residential finance-cost calculation rather than deducted as a normal expense. Nadia reconciles gross rent to agent payouts and adds the property result to her PAYE salary in the wider estimate. The example shows why cash outflow of more than £14,000 does not mean the same amount reduces taxable rental profit.
Travel, home administration and professional fees
Travel can be relevant where it is genuinely for managing the property business, such as an inspection, meeting an agent or arranging repairs, but private travel and ordinary personal journeys are not deductible merely because a property is nearby. Keep date, destination, purpose and mileage or receipts. Repeated travel to a distant property combined with personal visits requires careful allocation. Reasonable administrative costs, postage, phone and a business share of relevant home costs may be considered where supported, but a single rental property does not turn general household spending into property expenses. Accountancy fees for preparing property accounts can be relevant, while fees for personal financial planning, acquiring the property or defending title may have different treatment. Legal fees connected with short tenancy agreements can differ from capital legal work. Ask advisers to itemise mixed invoices. The same cost should not be claimed in both the property business and another trade. Keep a note explaining allocation where one subscription, vehicle or adviser serves several activities.
Empty periods, joint ownership and multiple properties
Expenses during a genuine temporary void can remain part of an ongoing property business when the property is available to let and the business has not ceased. Costs before the business begins, after it ends or while the property is used privately need separate consideration. Keep marketing evidence, dates, utility bills and notes showing availability. UK properties are generally pooled into one UK property business for income-tax profit and loss purposes, although specialist categories and uncommercial lets can be treated differently. Track each property separately for management, then prepare the combined tax schedule. Joint owners should keep the ownership and income-allocation evidence; married couples and civil partners have specific default and election rules that should not be replaced by whichever split gives less tax. If one owner pays an expense, record whether it changes the economic arrangement or is simply settled through the joint account. Overseas property belongs to a separate category and can involve foreign tax and currency issues.
Records and common landlord expense mistakes
Keep tenancy agreements, gross rent ledgers, agent statements, invoices, receipts, safety certificates, insurance, service-charge details, lender statements, replacement-item schedules and capital-improvement files. Reconcile each property monthly and store photographs or contractor descriptions for major work. Common mistakes include using net agent payouts as rent, deducting the whole mortgage payment, treating improvements as repairs, claiming the first furniture purchase as a replacement, ignoring reimbursements, mixing private and letting costs, and applying old furnished holiday letting rules after the special regime ended in April 2025. Another mistake is using the property allowance and actual expenses for the same property income. Review the complete method before filing, not one cost at a time. If the property has mixed use, connected-party rent, a large refurbishment, company ownership, holiday accommodation, overseas elements or uncertain beneficial ownership, specialist advice can be more valuable than an apparently precise online result.
