Most UK landlords leave hundreds of pounds in unnecessary tax on the table every year — not because their properties perform poorly, but because they under-claim the deductions HMRC explicitly permits. Allowable expenses for UK landlords are all legitimate revenue costs incurred wholly and exclusively for the rental business: letting agent fees, insurance, repairs, professional services, and more can all reduce your taxable rental profit and lower your annual income tax bill.
What are allowable landlord expenses? Allowable expenses are the revenue costs that HMRC accepts as deductible from UK rental income before calculating your tax liability. They must be incurred wholly and exclusively for the property rental business. Capital costs — buying furniture for the first time or extending a property — are generally not allowable as revenue expenses, though separate reliefs exist for some items. Note: mortgage interest is no longer a deductible expense for individual landlords; a 20% tax credit under Section 24 applies instead.
The "wholly and exclusively" rule
Every allowable expense must pass HMRC's core test: was the cost incurred wholly and exclusively for the purpose of the property rental business? Costs that serve a personal as well as a business purpose are not allowable unless the two elements can be clearly separated. A proportion of a mobile phone used partly for property management is allowable on the business-use fraction; a family holiday that included one property inspection does not become a deductible business trip merely because you checked in on a tenant while away.
The rule does not require costs to be only incurred in a single rental property — a landlord managing six properties can claim the full cost of an agent managing all of them. What it prohibits is claiming a cost that partly serves a personal purpose, unless that portion can be identified and excluded.
Fully allowable revenue expenses
The following categories are accepted by HMRC as allowable deductions against UK rental income, provided they are genuine, documented business costs:
| Expense category | Typical examples |
|---|---|
| Letting agent and management fees | Tenant-find fees, full management charges, renewal fees, inventory costs |
| Property advertising | Rightmove or Zoopla listings, local advertising, photography |
| Insurance | Buildings insurance, landlord liability, rent guarantee, legal expenses insurance |
| Repairs and maintenance | Like-for-like repairs only — fixing appliances, roof repairs, plumbing, decorating to restore condition |
| Utility bills paid by landlord | Gas, electricity, water during void periods or where the tenancy agreement requires it |
| Accountancy and bookkeeping fees | Annual accounts preparation, tax return submission, HMRC correspondence |
| Legal fees (not acquisition) | Lease renewal, reviewing new tenancy agreements, debt recovery — not purchase conveyancing |
| Gardening and cleaning | If provided under the tenancy agreement or during turnovers between tenants |
| Ground rent and service charges | Where the landlord pays these on a leasehold property, not passed directly to tenants |
| Council tax during voids | If the landlord is liable during vacant periods (check local authority rules on exemptions) |
| Professional subscriptions | NRLA, RLA or equivalent landlord association membership used for the business |
| Stationery and postage | Business correspondence, tenancy administration — pro-rata business-use portion |
According to HMRC's Property Income Manual, all of these costs may be deducted in the tax year they are incurred, provided the landlord's property letting constitutes a property business — which it does for any landlord receiving rent from residential or commercial property in the UK.
What you cannot deduct as a revenue expense
Two categories of expenditure are commonly — and incorrectly — claimed as allowable expenses by UK landlords:
Capital expenditure is not deductible as a revenue expense. If you install a new kitchen as an upgrade rather than replacing a broken one on a like-for-like basis, HMRC treats the whole cost as capital. Capital expenditure may qualify for relief against Capital Gains Tax when you eventually sell the property — as an enhancement to the base cost — but it does not reduce your annual rental income tax bill in the year of the spend.
Mortgage interest is no longer deductible as a revenue expense for individual landlords. Section 24 of the Finance (No.2) Act 2015, fully phased in by April 2020, replaced the deduction with a flat 20% tax credit on finance costs. HMRC's data shows the change increased the effective tax rate on the finance cost element by as much as 20 percentage points for higher-rate taxpayers — making accurate expense recording on all other allowable items more valuable than ever, since those savings remain fully intact.
Legal fees for purchasing a property, SDLT, surveys and conveyancing costs are also capital, not deductible as revenue expenses. They form part of the acquisition cost for future CGT purposes.
The repairs vs improvements distinction
The most contested line in landlord accounting is whether a cost is a repair (allowable revenue deduction) or an improvement (capital, not allowable). HMRC's position:
- Repairs (allowable): restoring an asset to its previous working condition without improving it. Replacing a broken boiler with an equivalent new boiler. Fixing a leaking flat roof. Repainting internal walls between tenancies.
- Improvements (capital, not allowable as revenue expense): upgrading to something better than what existed. Installing double glazing where single glazing stood. Replacing a basic bathroom suite with a high-specification wet room. Converting a garage into a habitable room.
The determining test is not the invoice amount — a large repair is still a repair. It is whether the character and standard of the asset has been improved. A practical rule of thumb: if you are replacing something broken with a reasonable modern equivalent, it is likely a repair. If you are taking the opportunity to upgrade, HMRC is likely to treat it as capital. When in doubt, document the pre-repair condition with photographs.
Replacement of Domestic Items Relief
Individual landlords cannot claim the original cost of furnishings as an expense. However, the Replacement of Domestic Items Relief — introduced in April 2016 to replace the old 10% Wear and Tear Allowance — allows the cost of replacing domestic items in a residential letting to be deducted in the year of replacement, subject to conditions:
- The property must be a residential letting (not commercial property).
- The item must be a replacement, not an addition to existing furnishings.
- The replacement must be of a broadly similar standard — if you upgrade to a premium equivalent, the deduction is capped at the cost of the like-for-like replacement.
- The deductible amount is the cost of the new item minus any disposal proceeds from the old item.
Items covered include sofas, beds, dining furniture, curtains and blinds, carpets and flooring, fridges, washing machines, dishwashers, televisions, and crockery. The relief applies to furnished and unfurnished residential lettings equally — it does not require the property to be fully furnished.
Pre-letting expenses
Expenses incurred before a property is first let may still be allowable if they would have been deductible once the property was in the rental business. HMRC accepts pre-letting expenditure provided the property was genuinely being prepared for letting and the costs are of the same type as those allowable once tenants are in place. Advertising costs, maintenance work and professional fees incurred while preparing for the first tenancy are typically allowable. The capital cost of acquiring or substantially refurbishing the property before first let is not — that forms part of the base cost for CGT.
Record-keeping: what HMRC expects
HMRC requires landlords to retain records supporting all expense claims for at least five years after the 31 January filing deadline for the relevant tax year. For a 2025/26 self-assessment return filed by 31 January 2027, records must be kept until at least 31 January 2032. The records must include:
- Receipts and invoices for all expenditure claimed
- Bank statements confirming payment
- Agent statements showing management fees deducted from rental income
- Mileage logs if claiming motor expenses
- Photographic evidence of condition for repair vs improvement disputes
Digital records — photographs of receipts, cloud-based accounting records, email invoices stored in folders by tax year — are fully accepted by HMRC and are far easier to maintain than paper files across a multi-property portfolio.
A worked example: how deductions reduce your tax bill
A landlord receives £14,400 gross annual rent on a single property (£1,200/month) with a £180,000 interest-only mortgage at 4.5% (£8,100 annual interest). They pay 40% income tax. Here is how expenses affect the bill:
| Item | Annual cost |
|---|---|
| Letting agent (10% + VAT) | £1,728 |
| Buildings and landlord insurance | £450 |
| Gas safety certificate | £85 |
| EICR (amortised over 5 years) | £70 |
| Repairs and routine maintenance | £620 |
| Accountancy fees | £350 |
| Total allowable deductions | £3,303 |
Taxable rental profit: £14,400 − £3,303 = £11,097. Income tax at 40%: £4,439. Less Section 24 mortgage interest credit (20% × £8,100 = £1,620). Net tax bill: £2,819.
Without claiming the allowable expenses, the landlord would pay 40% tax on the full £14,400 gross rent (£5,760), less the same £1,620 credit: a bill of £4,140. Accurate expense recording saves this landlord £1,321 per year on a single property — approximately £110 per month — from costs they were already incurring.
Frequently asked questions
Can I claim travel expenses to visit my rental property?
Yes, but only if the purpose of travel is wholly for the rental business — collecting rent, inspecting the property or overseeing repair work. HMRC permits actual costs or the approved mileage rate (currently 45p/mile for the first 10,000 business miles in a tax year). Incidental personal journeys on the same trip are not deductible. Keep a mileage log with dates, purpose, start and end points, and distances.
Can I deduct mortgage interest from rental income in 2026?
Not as a direct deduction. Section 24, fully phased in by April 2020, replaced the mortgage interest deduction with a flat 20% tax credit on finance costs. Individual landlords cannot deduct mortgage interest as an expense — they instead receive a credit worth 20% of the interest paid, applied against the income tax bill after tax is calculated on gross rental income. Limited companies are not subject to Section 24 and can still deduct mortgage interest in full as a business expense.
Is redecorating between tenancies an allowable expense?
Yes — redecorating to restore a property to its previous standard is a repair and is fully allowable. Decorating between tenancies as routine upkeep falls squarely within allowable maintenance. However, if the redecoration is part of a wider improvement project, HMRC may seek to treat the whole cost as capital enhancement. Document the work carefully and keep a record of the pre-work condition.
What is Replacement of Domestic Items Relief?
It allows the cost of replacing domestic furnishings — beds, sofas, white goods, curtains, carpets — to be deducted in the year of replacement. It does not cover the first purchase of furnishings, only replacements. If you upgrade to a better quality item, the deduction is limited to the cost of a like-for-like replacement. Introduced in April 2016, it replaced the old 10% Wear and Tear Allowance for all residential lettings.
Are HMRC penalties allowable expenses?
No. Fines and penalties imposed by HMRC or any other regulatory authority are never allowable as business expenses. The professional fees for responding to an HMRC enquiry or tax investigation are generally allowable, however — the advice to resolve a dispute about the rental business is itself a cost of the rental business.
