One of the most common questions landlords ask is: “What costs can I deduct from my rental income before calculating tax?”
The answer is not simply “anything connected with the property”. For an expense to be deductible, it generally needs to be incurred wholly and exclusively for the purposes of the property rental business. Capital expenditure, private costs and certain finance costs are treated differently.
The distinction matters because claiming too little can mean paying more tax than necessary, while claiming expenses incorrectly can cause problems if HMRC reviews your tax return. Here are the main costs landlords should consider.
How are rental profits calculated?
At a basic level: rental income minus allowable expenses equals taxable property profit.
If you own more than one UK rental property, HMRC will normally look at the income and expenses together as one UK property business. Profits from one property can usually be combined with losses or higher expenses arising from another property within the same business.
However, not every payment connected with a property is an allowable expense. The key distinction is usually between revenue expenditure, the ongoing cost of running, maintaining and managing the rental business, and capital expenditure, money spent acquiring, significantly improving or enhancing the property.
Revenue expenditure may be deductible against rental income. Capital expenditure generally is not, although some capital costs become relevant when calculating Capital Gains Tax when the property is eventually sold.
1. Repairs and maintenance
Normal repairs and maintenance are among the most common allowable landlord expenses. Examples include painting and decorating, repairing damaged doors or windows, treating damp, fixing a boiler, replacing damaged roof tiles, repairing gutters and plumbing, and repairing existing electrical systems.
A repair normally restores an asset rather than significantly improving it beyond its previous condition. The difficult part is deciding when a repair becomes an improvement.
Repairs vs improvements. Suppose an old kitchen is damaged and you replace it with a modern kitchen of broadly equivalent standard. The fact that the new kitchen uses modern materials does not automatically make the expenditure capital. However, if you replace a basic kitchen with a substantially higher specification kitchen, extend the room or significantly improve the property, some or all of the expenditure may be treated as capital.
This distinction can make a significant difference to the tax calculation, so landlords carrying out larger refurbishment projects should consider the tax treatment of the work before completing their Self Assessment return.
2. Letting agent and property management fees
Fees paid to letting agents and property managers for running the rental business are generally allowable. This can include finding tenants, collecting rent, managing the tenancy, arranging repairs, carrying out inspections and ongoing management.
Keep your agent’s monthly and annual statements. They are useful for confirming both rental income and the expenses deducted before the balance is transferred to you.
3. Insurance
Landlord insurance is normally deductible where it relates to the rental business. This may include buildings insurance, contents insurance, landlord liability cover and other qualifying property business insurance.
Where a policy covers both private and rental use, only the appropriate business element should be claimed.
4. Council tax, utilities and water rates
Where the landlord is responsible for paying council tax, water rates, gas or electricity, the qualifying business cost can normally be deducted. This often arises during void periods or where utilities are included within the rent charged to the tenant.
If the tenant pays these costs directly, the landlord cannot also claim them as an expense.
5. Ground rent and service charges
Landlords of leasehold properties commonly incur ground rent, service charges, maintenance charges and management company charges. These are generally deductible where they relate to the rental business.
Service charge statements should still be reviewed carefully. If part of the payment relates to a substantial capital improvement rather than routine maintenance, the tax treatment may be different.
6. Accountancy fees
Normal accountancy costs connected with the property business are generally allowable, including preparing rental accounts, bookkeeping, reviewing income and expenses, calculating property profits and dealing with the property related elements of Self Assessment.
Professional fees relating to other matters may need different treatment. For example, fees associated with purchasing or restructuring a property may be capital rather than deductible against annual rental income.
7. Legal fees
Some legal costs are deductible, while others are capital. Certain fees relating to tenancy matters or the normal operation of the rental business may qualify. By contrast, legal fees incurred when buying a property are generally capital and are not deducted from rental income. Those costs may instead become relevant when calculating Capital Gains Tax when the property is sold.
This is why landlords should avoid putting every solicitor’s invoice into a general legal expenses category without reviewing what the fee actually relates to.
8. Advertising and administration
Direct costs of running the rental business can generally be claimed, such as advertising for tenants, stationery, property related telephone costs, postage and certain administrative expenses.
Where an expense has both personal and business use, only the identifiable property business element should be claimed.
9. Cleaning, gardening and other services
Where you pay someone to provide services for the rental property, the cost is normally deductible. Examples include cleaners, gardeners, maintenance contractors and other service providers involved in running or maintaining the property. The important point is that the cost must genuinely relate to the rental business.
10. Travel and mileage
Travel expenses require more care than many landlords realise. Travel between properties, or from a genuine property business office to rental properties, may qualify where the journey is undertaken wholly and exclusively for the property business. However, travel from your home to a rental property is not automatically deductible. The position depends on the circumstances, including how and where the property business is managed.
Landlords who claim travel costs should keep a record showing:
- the date
- the destination and property visited
- the reason for the journey
- the mileage
11. Replacement furniture and appliances
Residential landlords may qualify for Replacement of Domestic Items Relief when replacing qualifying items provided for tenants, such as sofas, beds, tables, curtains, carpets, fridges, freezers, washing machines, crockery and kitchenware.
The important word is replacement. The relief does not provide a general deduction for furnishing a property for the first time. Where an existing item is replaced with a broadly equivalent new item, the replacement cost can generally qualify subject to the relevant conditions.
For example, an old washing machine needs replacing and a comparable replacement costs £450. That £450 may qualify. If you purchase a luxury replacement costing £1,200 when an equivalent would have cost £450, the full £1,200 may not necessarily be deductible.
12. Costs incurred before the first tenant
Some qualifying expenses incurred before the property business starts can be treated as property business expenses. That does not mean every refurbishment cost incurred before the first tenant moves in is deductible.
If you purchase a property in poor condition and carry out major works before it can be rented, some of that expenditure may be capital. Pre-letting expenditure should therefore be reviewed carefully.
What about mortgage payments?
A landlord cannot deduct the entire mortgage payment. The capital repayment element is not an allowable expense.
For individual residential landlords, mortgage interest and other qualifying finance costs are also subject to special rules. Rather than being deducted like ordinary property expenses, qualifying finance costs generally provide relief through a basic rate tax reduction. This means a landlord’s taxable property profit can be much higher than the actual cash left after mortgage payments.
The position is different where property is owned through a limited company. This is one reason landlords with significant borrowing should not calculate their tax position simply by looking at the balance left in their bank account.
What expenses cannot normally be claimed?
Common examples include:
- The cost of buying the property. The purchase price is capital expenditure.
- Mortgage capital repayments. Repaying the amount borrowed is not a rental business expense.
- Extensions and major improvements. These are normally capital rather than revenue expenditure.
- Private expenses. Personal expenditure cannot be claimed simply because you own rental property.
- Legal fees for purchasing the property. These are generally capital rather than deductible against rental income.
Capital expenditure should still be recorded carefully, because certain costs may be relevant when calculating Capital Gains Tax when the property is eventually sold.
What if you own several rental properties?
This is particularly important for portfolio landlords. Your UK rental properties are normally considered together when calculating the profit or loss of your UK property business.
For example, Property A makes a £12,000 profit, Property B makes £8,000 and Property C makes a £5,000 loss. The overall property business profit would broadly be £15,000, rather than treating the loss on Property C completely separately.
This is why landlords with multiple properties should consider their tax position across the whole portfolio.
What about the £1,000 Property Allowance?
Individuals may be able to use the £1,000 Property Allowance. However, if you claim it against the relevant property income, you cannot also deduct your actual property expenses against that same income.
For example, with rental income of £6,000 and actual allowable expenses of £2,500, claiming the actual £2,500 of qualifying expenses would normally be more beneficial than using the £1,000 allowance.
Landlords with significant costs should therefore compare the options rather than automatically claiming the Property Allowance.
A simple worked example
A landlord receives rental income of £24,000. During the year they pay letting agent fees of £2,400, insurance of £500, repairs of £1,600, service charges of £1,800, accountancy fees of £600 and other qualifying costs of £600.
Total ordinary allowable expenses come to £7,500. Before considering mortgage finance costs or any other adjustments: £24,000 minus £7,500 leaves a £16,500 property profit.
The treatment of mortgage interest would then need to be considered separately if the property is residential and owned personally. This shows why accurate expense records can make a meaningful difference to the final tax calculation.
Keep evidence for significant property costs
Landlords should retain invoices, receipts, bank statements, letting agent statements, mileage records, insurance documents, service charge statements and contractor invoices.
For major refurbishment projects, it is particularly useful to separate repairs from capital improvements while the work is taking place. Trying to reconstruct those costs several years later when the property is sold can be much more difficult.

Frequently asked questions
Can landlords claim repairs against rental income?
Normal repairs that restore the property without significantly improving it are generally deductible. Major improvements or extensions will normally be treated as capital expenditure instead.
Can landlords claim accountancy fees?
Normal recurring accountancy fees relating to the rental business and the associated tax reporting are generally deductible.
Can I claim my full mortgage payment?
No. Mortgage capital repayments are not deductible, and individual residential landlords are subject to special rules governing relief for mortgage interest and other finance costs.
Can landlords claim mileage?
Potentially. The journey must genuinely relate to the property business, and the circumstances of the travel need to be considered.
Can I claim the cost of replacing a washing machine?
Potentially. Replacement of a qualifying domestic item can fall within Replacement of Domestic Items Relief, provided the relevant conditions are met.
Can I claim renovation costs before renting the property?
Some qualifying pre-letting revenue expenses can be deductible. However, significant expenditure required to improve or substantially renovate a property may be capital.
