As a landlord in the UK, you pay Income Tax on your net rental profit — your rental income minus allowable expenses. Getting your expenses right is one of the most effective ways to reduce your tax liability legally.
This guide covers every category of allowable expense for residential landlords in 2025/26, the key restrictions that apply since Section 24, and common mistakes to avoid.
What Counts as an Allowable Expense?
HMRC allows landlords to deduct expenses that are incurred “wholly and exclusively” for the purposes of the letting business. Expenses that are partly personal (e.g. a car used for personal trips as well as property visits) must be apportioned.
Full List of Allowable Expenses for Landlords
1. Repairs and Maintenance
You can claim the cost of repairing your property to keep it in a lettable condition. This includes:
- Fixing a broken boiler, leaking roof or damaged windows
- Repainting and decorating between tenancies
- Replacing broken appliances (like-for-like only)
- Pest control
- Garden maintenance included in the tenancy
What you cannot claim: Improvements that add value (e.g. a new extension, converting a garage, or upgrading a standard kitchen to a premium one). These are capital expenditure and are instead set against any Capital Gains Tax liability when you sell.
2. Letting Agent Fees
All fees charged by a letting agent are fully deductible, including:
- Tenant-find fees
- Management fees (typically 10–15% of rent)
- Renewal fees
- Inventory check fees
3. Insurance
Premiums paid for landlord-specific insurance are fully allowable:
- Buildings insurance
- Contents insurance (for furnished lets)
- Rent guarantee insurance
- Landlord liability insurance
4. Accountancy and Professional Fees
Fees paid to an accountant for preparing your Self Assessment return or advising on your rental business are fully deductible. This includes:
- Accountancy and bookkeeping fees
- Tax advice fees
- Legal fees for drawing up tenancy agreements (but not legal costs to acquire the property)
5. Council Tax and Utility Bills
If you pay council tax or utility bills during void periods (when the property is empty between tenancies), these are allowable expenses. If your tenants pay their own bills, you cannot claim them.
6. Ground Rent and Service Charges
If you own a leasehold property, ground rent and service charges paid to the freeholder are deductible.
7. Travel Expenses
You can claim the cost of travelling to inspect a property, carry out repairs or meet tenants. This includes:
- Mileage at the HMRC approved rate (45p per mile for the first 10,000 miles)
- Public transport costs
- Parking fees
You cannot claim travel between your home and a letting agent’s office as that is a business commute — only travel directly to the property qualifies.
8. Advertising Costs
Costs of advertising your property for rent are deductible — Rightmove listings, Zoopla, OpenRent fees, and any other advertising spend.
9. Office Costs and Subscriptions
Stationery, software (including accounting software like Xero or QuickBooks), postage and professional subscriptions (e.g. a landlord association membership) are all deductible.
10. Replacement of Domestic Items (Furnished Lettings)
Since the Wear and Tear Allowance was abolished in 2016, furnished landlords can claim the Replacement of Domestic Items Relief. This allows you to deduct the cost of replacing items like:
- Furniture (sofas, beds, wardrobes)
- White goods (washing machine, fridge, oven)
- Carpets and flooring
- Curtains and blinds
The relief is for like-for-like replacement only. If you upgrade to a higher-spec item, only the cost of an equivalent replacement is deductible.
Section 24 — The Mortgage Interest Restriction
Since April 2020, landlords can no longer deduct mortgage interest as an expense when calculating rental profit. Instead, you receive a 20% tax credit on the interest paid.
For basic-rate (20%) taxpayers, the effect is broadly the same. But for higher-rate (40%) or additional-rate (45%) taxpayers, the restriction significantly increases the tax bill — because the credit is fixed at 20% regardless of your tax rate.
Example: How Section 24 Works in 2025/26
Scenario: Higher-rate taxpayer (40%) with:
- Rental income: £18,000/year
- Mortgage interest: £8,000/year
- Other expenses: £2,000/year
Old system (before Section 24):
Profit = £18,000 – £8,000 – £2,000 = £8,000. Tax at 40% = £3,200
New system (Section 24):
Profit = £18,000 – £2,000 = £16,000. Tax at 40% = £6,400. Minus 20% credit on £8,000 = £1,600. Net tax = £4,800
Extra tax under Section 24: £1,600/year
Landlords in this position often benefit from transferring properties to a limited company (though this comes with Stamp Duty and CGT implications on transfer), or restructuring their portfolio. This is where specialist landlord tax advice is invaluable.
What You Cannot Claim
- Capital improvements (adding an extension, converting a loft) — these reduce CGT when you sell
- Personal expenses with no business purpose
- The cost of purchasing the property
- Mortgage capital repayments (only the interest element qualifies for the tax credit)
- Costs of finding a mortgage or remortgaging (though arrangement fees can sometimes be spread)
- Fines or penalties (e.g. local authority fines)
Property Allowance — An Alternative to Expenses
If your total rental income is £1,000 or less, you don’t need to declare it. If it’s above £1,000, you can either:
- Claim the £1,000 Property Allowance instead of your actual expenses (simpler), or
- Deduct your actual allowable expenses (usually better if expenses exceed £1,000)
You cannot use both in the same year.
Keep Your Records
HMRC expects you to keep records for at least 5 years after the 31 January Self Assessment deadline for the relevant year. For rental property, this means:
- Receipts for all expenses claimed
- Rent statements and invoices
- Bank statements showing rental income and payments
- Mortgage statements showing interest charged
- Contracts and tenancy agreements
Are you claiming everything you’re entitled to?
Many landlords overpay tax simply because they don’t know what to claim. Our landlord accountants review your whole return before filing — and we often find expenses that were missed.
