Understanding landlord tax-deductible expenses in the UK is more important than ever in 2026. With rising property costs, tighter margins, and continued HMRC oversight, knowing exactly what expenses landlords can claim can have a direct impact on how much tax you pay on your rental income. Missing allowable deductions or claiming the wrong costs can quickly reduce profits or lead to unwanted HMRC attention.
This guide is built for UK landlords who want clarity and confidence. It breaks down the allowable expenses for landlords in 2026, explains what qualifies under current HMRC rules, and highlights common pitfalls to avoid. Before filing your return, speaking with an accountant can help ensure every claim is accurate, compliant, and working in your favour.
What Counts as a Tax-Deductible Expense for UK Landlords
For UK landlords, a tax-deductible expense is any cost that HMRC allows you to deduct from your rental income before tax is calculated. According to HM Revenue & Customs (HMRC), allowable expenses must be incurred solely for the purpose of running and maintaining your rental property. If an expense is personal, partly private, or not directly linked to the letting activity, it usually cannot be claimed in full.
In simple terms, if the cost helps you earn rental income or manage the property, it is likely to be allowable. This includes day-to-day running costs, professional fees, and certain finance costs, all of which are covered in later sections of this guide.
Revenue vs capital expenses explained simply
One of the most common areas of confusion for landlords is the difference between revenue and capital expenses.
Revenue expenses are ongoing costs related to maintaining the property in its existing condition. These are usually tax deductible in the year they are incurred. Examples include repairs, maintenance, insurance, and letting agent fees.
Capital expenses relate to buying, improving, or upgrading a property beyond its original condition. These costs are not deductible against rental income. Instead, they may be used to reduce Capital Gains Tax when the property is sold. Examples include extensions, loft conversions, or replacing basic fittings with higher-spec alternatives.
A useful rule of thumb is this: repairing or replacing like-for-like is usually revenue, while improving or upgrading is usually capital.
The “wholly and exclusively” rule in plain English
HMRC applies the “wholly and exclusively” rule to all landlord expenses. This means an expense must be incurred entirely for rental purposes to be fully allowable.
If a cost is partly personal and partly related to the property, only the rental portion can be claimed. For example, if you use your mobile phone for both personal calls and managing your rental property, only the proportion related to property management is allowable. Accurate records and reasonable calculations are essential here.
This rule is one of the main reasons HMRC challenges landlord claims, especially where personal and property costs overlap.
Common mistakes landlords still make
Despite clear guidance, many landlords continue to make avoidable errors, including:
- Claiming capital improvements as repairs
- Deducting personal expenses with no rental connection
- Forgetting to apportion mixed-use costs
- Assuming all mortgage payments are deductible
- Missing legitimate expenses due to poor record-keeping
Understanding these fundamentals early makes the rest of your expense claims far easier and reduces the risk of errors when submitting your return.
Property Running and Maintenance Costs You Can Claim
Running and maintaining a rental property comes with regular, unavoidable costs. The good news is that many of these day-to-day expenses are tax deductible, as long as they meet HMRC’s criteria and relate directly to the letting of the property.
Below are the most common and legitimately claimable running and maintenance costs UK landlords incur in 2026.
1. Repairs and maintenance
Repairs and maintenance are allowable when they keep the property in its existing condition rather than improve it.
Claimable examples include:
- Fixing leaks, broken boilers, or faulty electrics
- Repainting or redecorating between tenancies
- Replacing broken windows, doors, or roof tiles
- Like-for-like replacement of kitchen units or bathroom fittings
What does not qualify are improvements that upgrade the property beyond its original standard. For example, replacing basic laminate flooring with premium hardwood would usually be treated as a capital improvement rather than a deductible repair.
2. Cleaning and gardening
Cleaning and garden maintenance costs are deductible when they relate to the upkeep of the rental property.
This can include:
- End-of-tenancy cleaning
- Regular communal area cleaning in HMOs or blocks
- Lawn care, hedge trimming, or tree maintenance
- Clearance services after tenants move out
These costs are commonly overlooked, particularly for landlords managing properties themselves.
3. Safety checks and compliance costs
Expenses linked to legal safety requirements are fully allowable and increasingly important in 2026.
These include:
- Gas Safety Certificates
- Electrical Safety Reports
- Fire alarm and smoke detector testing
- Legionella risk assessments
- Carbon monoxide alarms
HMRC recognises these as necessary costs of letting a property safely and legally.
4. Replacement of domestic items relief
Landlords can claim relief for replacing domestic items provided to tenants, as long as the replacement is broadly like-for-like.
Eligible items include:
- Beds and mattresses
- Sofas and chairs
- Fridges, freezers, and washing machines
- Curtains and carpets
The cost of the replacement item can be claimed, but the initial purchase of furnishing a property for the first time is not deductible.
5. Council tax, utilities, and ground rent
These costs are deductible when the landlord is responsible for paying them.
This typically applies when:
- The property is empty between tenancies
- Utilities are included in the rent
- Council tax is paid during void periods
- Ground rent and service charges are paid by the landlord
If tenants pay these costs directly, they cannot be claimed by the landlord.
Understanding which running costs qualify sets the foundation for accurate and defensible expense claims. Next, we’ll look at professional and management fees that landlords often miss or miscategorise.
For a broader view, see our 2026–27 UK tax rates and allowances guide to understand how current thresholds may affect your tax bill.
Letting Agent, Management, and Professional Fees
Professional and management fees are among the most common costs landlords incur, yet they are also some of the most underclaimed expenses. HMRC generally allows these costs as long as they are reasonable and directly related to letting the property.
You can usually claim the following fees:
- Letting agent fees: Typically range from around 6%–12% of annual rent for tenant-find services, or 8%–18% of monthly rent for rent collection or full management packages.
- Property management charges: Often included within full management fees, but standalone management costs for HMOs or blocks commonly range from £50–£200+ per month depending on the level of service.
- Accountancy and bookkeeping costs: Basic landlord tax returns usually cost £150–£300 per year, while landlords with multiple properties or more complex affairs often pay £300–£800+ annually. Ongoing bookkeeping support may add £30–£100 per month.
- Legal fees related to tenancy agreements: Drafting or reviewing tenancy agreements typically costs £100–£250. Notices or tenancy-related legal actions often range from £150–£300, with more complex cases costing more, provided the fees relate specifically to the rental activity.
- Advertising for tenants: Listing and marketing costs commonly range from £50–£300 per listing, with optional extras such as professional photography or floorplans costing around £100–£250.
These professional costs are often underclaimed because landlords view them as optional rather than essential. In reality, HMRC treats reasonable professional and management fees as a normal part of running a rental business, provided they are wholly for letting purposes.
Next, we’ll look at mortgage interest and finance costs, an area where many landlords still make costly assumptions.

Mortgage Interest and Finance Costs in 2026
Mortgage interest is no longer deducted directly from rental income for most UK landlords. Instead, HMRC applies a basic rate tax credit, which changes how relief works in 2026 and often affects higher-rate taxpayers the most.
Landlords can still receive relief on qualifying finance costs, including mortgage interest, interest on loans used to buy or improve a rental property, and certain arrangement or refinancing fees. Rather than reducing taxable profit, these costs qualify for a tax credit equal to 20% of the eligible finance costs, which is applied after tax is calculated.
The key requirement is that the borrowed money must be used wholly for property-related purposes. Capital repayments are not deductible, and interest on personal borrowing cannot be claimed. Many landlords still make the mistake of deducting interest as an expense or assuming all loan payments qualify, which can lead to incorrect returns and unexpected tax bills.
Insurance and Protection Costs
Insurance is a necessary cost of protecting a rental property and is generally fully allowable when it relates directly to the letting activity.
Landlords can usually claim:
- Landlord insurance: Covers risks specific to rental properties, including damage, loss of rent, and legal expenses.
- Buildings and contents cover: Insurance for the structure of the property and any landlord-owned furnishings or appliances provided to tenants.
- Rent guarantee insurance: Premiums for policies that protect against tenant non-payment of rent are allowable as a business expense.
- Public liability cover: Insurance that protects against injury or damage claims made by tenants or visitors.
Insurance linked to the rental business is allowable, but personal insurance policies are not. Claims should always relate specifically to the property being let, not your personal residence or unrelated cover.
Travel, Mileage, and Home Office Expenses
Travel and home working costs can be claimed when they are necessary for managing your rental property, but they are closely scrutinised by HMRC.
Allowable travel includes:
- Visiting the property for inspections or maintenance
- Meeting letting agents or contractors
- Attending compliance checks or repairs
Mileage can be claimed using HMRC’s approved rates, provided journeys are recorded accurately. Alternatively, landlords can claim actual travel costs such as public transport fares and parking fees. Fines and penalties are never allowable.
Using your home as an office:
If you manage your rental property from home, you may be able to claim a proportion of household costs such as:
- Heating and electricity
- Internet and phone usage
- Office supplies
Only the portion used for rental administration is allowable, and claims should be reasonable and supported by records.
Practical examples landlords relate to:
A landlord driving to inspect a property between tenancies, paying for train travel to meet a managing agent, or using their home internet to handle tenant communications may all have allowable costs, provided they relate solely to the rental activity.
Utility, Service, and Admin Expenses
Many ongoing admin and service costs are deductible when the landlord is responsible for paying them.
Commonly allowable expenses include:
- Utility bills paid by the landlord during void periods or when utilities are included in the rent
- Service charges and management fees for flats or managed buildings
- Phone and internet costs used for property management
- Stationery, postage, and general admin expenses
- Software and digital tools used for rent tracking, accounting, or property management
As with other expenses, costs must relate directly to the rental business. Where services are used for both personal and rental purposes, only the appropriate proportion should be claimed.
What Landlords Cannot Claim (And Why)
Knowing what you cannot claim is just as important as knowing what you can. Incorrect claims are one of the main reasons HMRC challenges landlord tax returns, so clarity here helps protect you from errors and penalties.
1. Capital improvements
Capital improvements are costs that enhance or upgrade a property beyond its original condition. These are not deductible against rental income.
Examples include:
- Extensions or loft conversions
- Installing higher-spec kitchens or bathrooms
- Adding new features such as conservatories
These costs may reduce Capital Gains Tax when you sell the property, but they cannot be claimed as rental expenses.
2. Personal expenses
Any cost that is personal rather than related to the rental business is not allowable.
This includes:
- Personal phone or internet use
- Travel that is not property-related
- Home expenses unrelated to rental admin
Only expenses incurred wholly for the letting activity can be claimed.
3. Initial property purchase costs
The costs of buying a rental property are not deductible from rental income.
These include:
- Property purchase price
- Stamp Duty Land Tax
- Solicitor and conveyancing fees
- Survey costs
These are treated as capital costs and may be relevant when calculating Capital Gains Tax in the future.
4. Fines and penalties
HMRC does not allow the deduction of fines or penalties, even if they arise during the course of letting.
Examples include:
- Late filing penalties
- Council fines
- Safety breaches or compliance penalties
These costs are considered avoidable and non-business-related.
5. Private use apportionment explained
Where an expense is partly personal and partly related to your rental property, only the rental portion is allowable.
For example:
- A mobile phone used for both personal calls and tenant communication
- Home internet used for both personal browsing and rental admin
In these cases, landlords must apportion the cost fairly and keep records to support the calculation.
Understanding these exclusions helps avoid overclaiming and keeps your tax return defensible if HMRC ever asks questions.

Record-Keeping and Evidence HMRC Expects
Good record-keeping isn’t just good practice—it’s a requirement when you claim landlord tax-deductible expenses and report rental income to HMRC.
What records to keep
HMRC expects landlords to keep clear evidence of all income and expenses used in your tax return. This includes:
- Dates when you let out each property and tenancy agreements
- Rent received, including rent books, bank statements and receipts
- Details of all allowable expenses you claim, such as repairs, insurance, and agent fees
- Supporting invoices, receipts and contracts relating to those expenses
These records show HMRC how you calculated your rental profits and justify the deductions you’ve claimed.
Digital vs paper receipts
Until April 2026, landlords can maintain records on paper or digitally. However, from 6 April 2026, many landlords with gross income over £50,000 must keep digital records and report them using HMRC-compatible software under Making Tax Digital for Income Tax.
Digital records must show the amount, date and category for each income or expense item and be stored in software that can submit updates to HMRC.
How long to retain documents
HMRC rules generally require landlords to keep self-assessment records for at least five years after the 31 January deadline following the relevant tax year. For example, records supporting a 2025/26 return filed by 31 January 2027 should be kept until at least January 2032.
Many landlords keep records for six years, which covers most HMRC enquiries and supports future Capital Gains Tax calculations if the property is sold.
Making Tax Digital considerations for landlords
From April 2026, if your combined property and self-employment income exceeds £50,000, you must keep digital records and make quarterly submissions of income and expenses using HMRC-approved software.
This means updating your records regularly, not just at tax-return time, and ensuring data is stored digitally in a way HMRC accepts.

Wrapping up

FAQs
Are all landlord expenses tax deductible in the UK?
No. Only expenses that are incurred wholly and exclusively for rental purposes are allowable under HM Revenue & Customs rules. If an expense is partly personal, only the rental-related portion can be claimed.
Can landlords still claim mortgage interest in 2026?
Mortgage interest is no longer deducted from rental income when calculating profit. Instead, eligible finance costs qualify for a basic rate tax credit, which reduces the final tax bill rather than taxable income.
Do repairs count as deductible expenses?
Yes, provided the work restores the property to its original condition. Repairs and like-for-like replacements are generally allowable, while improvements or upgrades are treated as capital costs.
Can I claim mileage for visiting my rental property?
Yes, if the travel is solely for managing the rental property, such as inspections or maintenance visits. Accurate records of journeys and costs are essential.
Should landlords use an accountant for tax returns?
Many landlords choose to use an accountant to ensure expenses are claimed correctly, records meet HMRC standards, and future tax planning is handled efficiently.
