Rental Property Expenses You Can Claim as a UK Landlord

Many landlords pay more tax than they need to. Not because they want to, but because they do not fully understand which rental property expenses they can claim.

The difference between knowing and not knowing can be thousands of pounds each year. Landlords who properly track their expenses typically reduce their taxable profit by 25-40%, saving between £2,000 and £5,000 annually.

This guide explains what rental property expenses you can legally deduct from your rental income and how to claim them correctly.

How Rental Property Expenses Work?

In the UK, you pay tax on your rental profit, not your total rental income. Your profit is calculated by subtracting your allowable expenses from the rent you receive.

The formula is simple:

Net Rental Profit = Gross Rental Income – Allowable Expenses

The more legitimate expenses you claim, the lower your taxable profit and the less tax you pay. However, HMRC has strict rules about what qualifies as an allowable expense.

The golden rule is that expenses must be incurred wholly and exclusively for the purpose of renting out the property. If an expense serves both personal and rental purposes, it generally cannot be claimed.

Common Allowable Expenses for Landlords

Several categories of rental property expenses qualify as allowable deductions.

Property Maintenance and Repairs

Routine maintenance and repairs are fully deductible. This includes fixing leaks, replacing broken windows, repainting between tenancies, plumbing repairs, electrical work, and damp proofing.

The key distinction is between repairs and improvements. Repairs restore something to its original condition and are allowable. Improvements add value or upgrade the property and are not deductible against rental income.

For example, replacing a broken boiler with a similar model is a repair. Installing a brand new heating system where none existed is an improvement.

Insurance Premiums

Landlord insurance policies are fully allowable. This includes buildings insurance, contents insurance, public liability insurance, and rent guarantee insurance. These protect your investment and qualify as legitimate business costs.

Letting Agent and Management Fees

Fees paid to letting agents for tenant finding, rent collection, and property management are deductible. For many landlords, these represent significant annual costs that reduce taxable profit considerably.

Professional Fees

Accountancy fees for preparing rental accounts and tax returns are allowable. Legal fees for tenancy agreements, eviction proceedings, and other property-related matters also qualify, provided they relate to the rental business rather than property purchase.

Utility Bills and Council Tax

If you pay utility bills or council tax for your rental property, these costs are deductible. This commonly applies to Houses in Multiple Occupation or during void periods when the property sits empty between tenants.

Ground Rent and Service Charges

For leasehold properties, regular ground rent and service charges are allowable expenses. These are direct costs associated with owning the property for rental purposes.

Replacement of Domestic Items Relief

Landlords cannot claim for initially furnishing a property. However, the Replacement of Domestic Items Relief allows you to claim when replacing worn-out items.

This covers furniture, appliances, carpets, curtains, beds, sofas, and white goods. The important rule is that you can only claim the cost of a like-for-like replacement.

If you replace a £200 washing machine with a £400 model, you can only claim £200. The additional cost is considered an upgrade, not a replacement.

Mortgage Interest: The Section 24 Rules

Mortgage interest deserves special attention because the rules changed significantly.

Since April 2020, landlords can no longer deduct mortgage interest directly from rental income. Instead, you receive a 20% tax credit on your finance costs.

For example, if you pay £6,000 in mortgage interest annually, you receive a £1,200 tax credit applied against your overall tax liability. This change particularly affects higher-rate taxpayers who previously benefited from full interest deductions.

Note that only the interest portion of mortgage payments qualifies. Capital repayments are never deductible.

Expenses You Cannot Claim

Understanding what you cannot claim is equally important.

Capital improvements like extensions, loft conversions, or upgrading single glazing to double glazing are not allowable against rental income. However, keep records of these costs as they can reduce your Capital Gains Tax liability when you sell.

Personal expenses, clothing, and costs with dual personal and business purposes do not qualify. The full mortgage payment, including capital repayment, is also not deductible.

Keeping Proper Records

HMRC requires landlords to keep records for at least five years after the 31 January submission deadline. This includes receipts, invoices, bank statements, and any documentation supporting your expense claims.

Good record-keeping protects you during HMRC enquiries and ensures you claim everything you are entitled to. Consider using digital accounting software, especially with Making Tax Digital requirements approaching from April 2026.
