If you are a UK landlord, understanding allowable expenses for landlords is essential to reducing your tax bill. HMRC does not tax you on your total rent received; it taxes you on your rental profit after deducting allowable rental expenses.
This guide explains what expenses landlords can claim against rental income, which tax reliefs apply, and where landlords often make costly mistakes.
What Are Allowable Expenses for Landlords?
HMRC defines allowable expenses as costs that are:
Wholly and exclusively incurred for the purpose of letting a property.
If an expense is partly personal and partly business-related, only the business proportion is deductible.
Common Allowable Rental Expenses (HMRC-Approved)
Repairs and Maintenance (Not Improvements)
Landlords can claim:
-
Repairs to roofs, boilers, plumbing, electrics
-
Repainting and redecorating between tenants
-
Replacing broken fixtures and fittings
🔹 Key rule:
Repairs are allowable; capital improvements are not.
For example, replacing a broken kitchen is allowable, but upgrading a basic kitchen to a luxury one is not.
Replacement of Domestic Items Relief
Landlords can claim the cost of replacing:
-
Beds, sofas, wardrobes
-
Carpets and curtains
-
Fridges, washing machines, cookers
❌ The initial purchase is not deductible
✅ Replacements are fully allowable
Letting Agent & Property Management Fees
You can deduct:
-
Letting agent commissions
-
Property management fees
-
Tenant-finding fees
These are standard allowable expenses for buy-to-let landlords.
Professional Fees
Allowable costs include:
-
Accountant’s fees for rental accounts and tax returns
-
Legal fees for tenancy agreements
-
Surveyor’s fees relating to rental management
❌ Legal fees for buying or selling property are not allowable.
Insurance Premiums
Landlords can claim:
-
Buildings insurance
-
Landlord contents insurance
-
Public liability insurance
-
Rent guarantee insurance
These are fully deductible as property rental tax reliefs.
Utility Bills & Council Tax
If the landlord pays these costs, they are allowable:
-
Gas, electricity, water
-
Council tax
-
TV licence (if provided to tenants)
If tenants pay directly, no deduction is allowed.
Mortgage Interest & Finance Costs (Section 24 Rules)
Can landlords claim mortgage interest?
Mortgage interest is no longer deducted from rental profits.
Instead, landlords receive:
-
A 20% basic-rate tax reduction on finance costs, including:
-
Mortgage interest
-
Loan interest
-
Arrangement and renewal fees
-
This rule (often called Section 24) significantly impacts higher-rate taxpayers.
Leasehold Costs
For leasehold properties, landlords can usually claim:
-
Service charges
-
Ground rent
-
Maintenance contributions
As long as these are not for capital improvements.
Advertising & Tenant-Related Costs
Allowable rental expenses include:
-
Advertising for tenants
-
Referencing and credit checks
-
Inventory and check-in/check-out reports
These are considered part of managing the rental business.
Travel & Mileage Expenses (With Caution)
Landlords may claim reasonable and necessary travel costs incurred wholly and exclusively for the purpose of running their property business. These expenses must relate directly to managing or maintaining the rental property rather than personal travel.
Allowable travel costs may include:
-
Visiting the rental property to carry out inspections, oversee repairs, or deal with maintenance issues
-
Meeting letting agents to discuss tenancy matters, renewals, or compliance requirements
-
Visiting contractors or suppliers in connection with repairs, renovations, or safety work
-
Travel to purchase materials needed solely for the upkeep of the rental property
If you use your own vehicle, you can usually claim either:
-
HMRC’s approved mileage rates (for example, 45p per mile for the first 10,000 miles, then 25p thereafter), or
-
A proportion of actual running costs, based on business use
However, claims must be proportionate and justifiable. HMRC may challenge:
-
Excessive mileage claims
-
Regular long-distance journeys where closer alternatives exist
-
Travel that has a dual purpose, such as combining property visits with personal trips
Importantly, travel from home to a property that is effectively treated as a normal place of business may be viewed as ordinary commuting and therefore not allowable. Each case depends on the facts, particularly where landlords manage properties personally.
To protect your position, you should:
-
Keep detailed mileage logs or receipts
-
Record the purpose of each journey
-
Ensure claims clearly relate to your property business activity
Because travel expense rules can be complex and fact-specific, landlords should take professional advice to ensure claims are compliant and defensible if reviewed by HMRC.
Home Office Expenses for Landlords
You may claim a reasonable proportion of certain household expenses, including:
-
Electricity and gas
-
Heating and water
-
Broadband and phone costs
-
Council tax (in limited circumstances)
The proportion claimed should reflect:
-
The number of rooms used for business
-
The amount of time those rooms are used for property-related activities
For example, if one room is used as a home office for property management for part of the week, only a fair and justifiable percentage of the total household costs should be claimed.
Costs such as mortgage capital repayments and domestic living expenses are not allowable. Care should also be taken not to claim expenses that are predominantly private in nature.
Using HMRC’s Simplified Home Office Allowance
As an alternative, HMRC allows a simplified home office allowance, which provides a flat-rate deduction based on the number of hours you work from home each month. This method avoids complex calculations and record-keeping.
While the simplified method is easier to administer, it may result in a lower deduction than claiming actual costs, particularly when a dedicated home office is used regularly.
Important Points to Note
-
Claims must be reasonable, consistent, and well-documented
-
You should retain utility bills and usage records to support your calculations
-
Using a room exclusively for business may have capital gains tax implications when the property is sold
Because home office claims can affect both income tax deductions and future capital gains relief, landlords should review their position carefully and seek professional advice to ensure the claim is both tax-efficient and compliant.
Legal, Safety & Compliance Costs
Landlords can claim:
-
Gas Safety Certificates
-
EPCs and EICRs
-
HMO licence fees
-
Right-to-Rent checks
These are mandatory and fully allowable.
Pre-Letting Expenses (Up to 7 Years Before Letting)
HMRC allows certain pre-letting expenses incurred up to 7 years before first letting, including:
-
Repairs
-
Advertising
-
Professional fees
As long as the costs would have been allowable if incurred during the rental period.
Expenses Landlords Cannot Claim
Common disallowed expenses include:
-
Capital improvements
-
Personal costs
-
Fines and penalties
-
Capital element of mortgage repayments
-
Clothing or private expenses
Misclassifying expenses can result in HMRC penalties and interest.

-
Pay the correct amount of tax
