Allowable Expenses for Landlords: What You Can and Cannot Deduct

landlord expenses, rental profits, HMRC rules, and practical tax planning trade-offs.

If you let out residential property in the UK, your tax bill depends not only on the rent you collect but on which expenses you can properly set against that income.

This is where many landlords come unstuck.

Some claim too little and pay more tax than necessary.

Others claim too much, often because they confuse a genuine revenue cost with a capital improvement, or assume that any property-related spending must be deductible.

HMRC's basic rule sounds simple: you can deduct expenses that are incurred wholly and exclusively for the purposes of the rental business.

In practice, that raises several awkward questions.

Is replacing a kitchen a repair or an improvement?

Can you claim mileage to visit the property?

What about service charges, mortgage costs, legal fees, furniture, insurance, and using your own home as an office?

This guide sets out what UK landlords can and cannot usually deduct from rental income, where the grey areas sit, and how to approach record-keeping so that your figures stand up if HMRC ever asks questions.

Start with the core rule: revenue expenses versus capital expenses

Before looking at categories of cost, it helps to split landlord spending into two broad types:

• Revenue expenses — day-to-day running costs of the rental business.

  These are normally deductible from rental income in the tax year they are incurred.

• Capital expenses — costs of acquiring, improving, or enhancing the property, or creating an enduring asset.

  These are generally not deducted from rental income, though they may matter later for Capital Gains Tax when you sell.

This distinction matters because many expensive items sit close to the line.

A like-for-like repair is usually revenue.

Upgrading beyond what was there before may be capital.

Replacing a worn-out asset can still count as revenue in some cases, particularly where the modern replacement is the nearest current equivalent, but extending, enlarging or substantially improving the property usually points the other way.

HMRC is less interested in what you call a cost in your spreadsheet than in what the spending actually achieved.

For example, if you replace a broken single-glazed timber window with a modern double-glazed uPVC window, that can still be treated as a repair rather than an improvement, because modern materials are often simply the current equivalent.

But if you convert a basic galley kitchen into a large open-plan kitchen-diner with structural work and significantly better specifications, that is far more likely to be capital.

What landlords can usually deduct from rental income

The following categories are commonly allowable against UK rental income, assuming they relate wholly and exclusively to the let property business.

1.

Letting agent and management fees

Fees paid to a letting agent for finding tenants, rent collection, inspections, arranging repairs, check-in and check-out services, and ongoing management are normally deductible.

So are tenant referencing fees paid by the landlord, inventory costs, and charges for tenancy renewals, where these are part of managing the let.

If the agent deducts fees before passing rent to you, do not assume your rental income is only the net amount received.

You should generally account for the gross rents and then deduct the fees as an expense.

2.

Repairs and maintenance

Repairs are one of the biggest areas of confusion.

Broadly, the cost of restoring an asset to its original condition is usually allowable.

Common examples include:

• Fixing a leaking roof

• Replacing broken roof tiles

• Redecorating between tenancies

• Repairing plasterwork after damp treatment

• Replacing a faulty boiler with a modern equivalent

• Fixing gutters, pipes, locks, sockets and fences

Maintenance and small renewals are also generally allowable.

If a tenant leaves and you repaint scuffed walls, replace damaged internal doors, or repair kitchen units, these costs are usually revenue in nature.

3.

Replacement of domestic items

For residential landlords, relief may be available when you replace domestic items provided for tenants.

This applies to items such as:

• Beds and mattresses

• Sofas and armchairs

• Wardrobes and drawers

• Carpets and flooring

• Curtains and white goods

• Crockery and cutlery in furnished lets

The relief is generally based on the cost of replacing the old item with a new one, less any proceeds from disposal of the old item, and excluding any element that represents an improvement.

So if you replace a cheap freestanding fridge with a similar model, the full replacement cost is likely to qualify.

If you upgrade substantially to a premium integrated appliance system, the excess over the equivalent replacement may not.

This relief is for replacement, not the initial cost of furnishing a property for first letting.

The first purchase of furniture for a newly let residential property is not deductible under these rules.

4.

Utility bills, council tax and service charges paid by the landlord

If your tenancy arrangement means you pay gas, electricity, water, broadband, TV packages, council tax or similar running costs for the property, these can usually be deducted.

The same applies to ground rent and service charges on leasehold flats, provided they relate to the period of letting and are revenue rather than capital in nature.

Be careful with major works bills on leasehold properties.

A routine annual service charge is generally deductible.

A one-off contribution towards structural improvement or enhancement to the building may not be.

5.

Insurance

Landlord insurance premiums are generally allowable, including buildings insurance, contents insurance for furnished lets, public liability cover and rent guarantee policies.

If you also have personal protection policies bundled in, the private element should not be claimed.

6.

Advertising and tenant sourcing costs

Advertising for tenants, online listing charges, professional photography for letting purposes, and associated costs of marketing the property are usually deductible.

These are normal business expenses of securing rental income.

7.

Accountancy, bookkeeping and some professional fees

Fees paid to an accountant for preparing rental accounts and tax returns are usually deductible to the extent they relate to the rental business.

Bookkeeping software and bookkeeping support can also qualify.

Some legal and professional fees are allowable, but this depends heavily on what they are for.

Legal fees relating to tenancy agreements, rent recovery, or eviction proceedings are usually revenue expenses.

Legal fees on buying or selling the property are usually capital and not deducted from rental income.

8.

Wages for gardeners, cleaners and other staff

If you employ or contract people to clean communal areas, maintain gardens, handle minor maintenance, or manage a block connected with your lettings, those costs are usually deductible.

If you employ relatives, the payments must be commercially justifiable and actually paid.

9.

Travel costs for managing the let

Landlords can generally claim travel costs incurred wholly and exclusively for the rental business.

Common examples include journeys to:

• Inspect the property

• Meet contractors or agents

• Attend the property to deal with repairs

• Purchase supplies for the let

Car mileage may be claimed using actual running costs apportioned for business use, or in some cases using HMRC's approved mileage rates where appropriate.

Public transport, parking and tolls connected with property business travel can also qualify.

Ordinary commuting does not usually apply in the same way as it does to employment, but travel must still have a genuine business purpose.

A trip that is mainly personal, with a quick stop at the rental flat, is risky to claim in full.

10.

Office costs and phone use

If you run your property business from home, a reasonable proportion of home office costs may be deductible, such as stationery, printing, business phone calls and a modest share of household running costs where there is genuine business use.

This needs care.

A small and reasonable apportionment is often more defensible than an aggressive one.

For many landlords with one or two properties, the amounts involved are relatively modest.

Mortgage interest and finance costs: deductible or not?

This is one of the biggest changes to landlord tax in recent years.

For individual landlords holding residential property, finance costs such as mortgage interest, loan interest, mortgage arrangement fees and some similar costs do not reduce rental profit in the old way.

Instead, you generally receive a basic rate tax reduction equal to 20% of the allowable finance costs, subject to the usual rules.

That means a higher-rate or additional-rate taxpayer may not get full relief at their marginal rate.

It can also push up "taxable income" figures used for child benefit charges, personal allowance tapering, and similar calculations, because the finance costs no longer reduce the rental profit figure itself.

There are exceptions and different rules depending on the type of property and ownership structure.

Companies are taxed differently, and furnished holiday lets have historically had different treatment, though that area has been subject to change and landlords should check the current rules for the relevant tax year.

What landlords usually cannot deduct from rental income

Knowing what is not allowable is just as important.

These are common examples.

1.

The cost of buying the property

The purchase price of the property is not deductible from rental income.

Nor are Stamp Duty Land Tax, conveyancing fees on acquisition, survey fees connected with purchase, or mortgage broker fees tied to buying the property.

These are usually capital costs.

Some of these may form part of your Capital Gains Tax base cost when you sell, but they do not reduce rental profits year by year.

2.

Capital improvements

Improvements and additions are generally not deductible from rents.

Examples include:

• Building an extension

• Loft conversions that add new living space

• Installing an extra bathroom where none existed before

• Upgrading a basic property to a significantly higher specification

• Adding a conservatory

The line can be fine.

If you replace worn kitchen units with standard modern units in the same layout, that is often revenue.

If you knock through walls, install underfloor heating, move plumbing, and create a premium fitted kitchen beyond the old standard, there is likely to be a capital element.

3.

Personal expenses and private use

If an expense has a private element, that part cannot be claimed.

Examples include using the property yourself for part of the year, combining a family trip with a brief property visit, or including your personal mobile contract in "office costs" without a fair apportionment.

4.

Your own time

You cannot charge your rental business for your own labour unless you operate through a structure that genuinely employs you and accounts for that correctly.

An individual landlord spending a weekend repainting a flat cannot claim a fictional labour cost for their own time.

5.

Fines and penalties

Late filing penalties, tax interest charged by HMRC, parking fines, and penalties for regulatory breaches are not allowable deductions.

6.

Loan repayments

The capital repayment part of a mortgage is not deductible.

This catches many new landlords out.

Only the interest and certain finance-related charges are relevant, and for individual residential landlords even those usually fall under the basic rate tax credit system rather than an income deduction.

A practical table: common landlord costs and likely treatment

The repair versus improvement problem: how to judge it in practice

When landlords ask whether something is deductible, this is usually the real issue.

A useful framework is to ask four questions.

Question 1: Was there already something there before?

If you are replacing an existing asset, that supports a repair analysis.

If you are creating something new, that leans towards capital.

Example: Replacing rotten decking at the back of a rented house with similar decking is more likely to be revenue.

Creating a new raised patio where there was previously only grass is more likely capital.

Question 2: Are you restoring or enhancing?

If the work simply puts the property back into usable condition, that usually helps the case for deductibility.

If it substantially improves the asset or increases the property's value beyond normal modern replacement, that points towards capital.

Question 3: Is any "upgrade" just the modern equivalent?

Modern materials often outperform old ones.

HMRC does not automatically treat that as capital.

Replacing old pipework with current materials, or installing a modern boiler where the old model is obsolete, can still be revenue.

Question 4: Was the property in disrepair when purchased?

This area needs special care.

If you buy a property in a poor state and spend heavily to put it into a rentable condition for the first time, HMRC may argue that some or all of that expenditure is capital because it was reflected in the purchase price.

The fact that the work looks like "repair" does not guarantee a revenue deduction if it is effectively part of the acquisition cost of making the asset usable.

Pre-letting expenses: can you claim costs before the first tenant moves in?

Some expenses incurred before the rental business starts can still be deductible if they would have been allowable had they been incurred after the business began, and they were incurred within the relevant period before commencement.

This may cover items such as advertising for tenants, initial safety certificates, or minor repairs shortly before the first letting.

But capital costs remain capital.

If you spend £18,000 replacing kitchens and bathrooms to bring a neglected flat up to standard before the first letting, the deductibility of that spending depends on the nature of the work, and HMRC may take a stricter view because the property was not yet in a fit state to produce rental income.

Mixed-use costs and apportionment

Many landlord expenses are not neatly 100% business or 100% private.

In those cases, a fair apportionment is needed.

Typical examples include:

• A mobile phone used partly for tenant calls and partly personally

• Home broadband used for property administration and household use

• Car running costs where only some journeys relate to the let

• Professional fees covering both rental business and personal tax planning

The key word is reasonable.

HMRC does not expect artificial precision where that is impossible, but it does expect a sensible basis.

That could be itemised business calls, estimated floor area and time for a home office apportionment, or a mileage log for property visits.

Examples of how the rules apply in real UK landlord situations

Example 1: Replacing a boiler in a Manchester terrace

A landlord replaces a failed combi boiler in a tenanted house for £2,600.

The old model is obsolete, and the new one is more efficient.

This is usually treated as a repair and deductible as a revenue expense, because it replaces an existing asset with a modern equivalent.

Example 2: Upgrading a flat in Bristol before first let

A buyer completes on an ex-owner-occupied flat needing significant work.

They spend £14,000 on rewiring, replastering, a new kitchen and a bathroom before the first tenant moves in.

Some elements may appear to be repairs, but because the work is substantial and carried out before the property is first put into the rental business, HMRC may argue that much of it is capital or otherwise non-deductible against income.

Example 3: New furniture in a Leeds buy-to-let

A landlord lets an unfurnished flat for two years, then decides to furnish it and buys a bed, sofa and dining table.

These are initial purchases, not replacements of existing domestic items, so they are not usually deductible under replacement of domestic items relief.

Example 4: Replacing worn carpets in a Birmingham semi

Long-standing carpets are worn out after a tenancy.

The landlord replaces them with similar mid-range carpets.

This is typically allowable under replacement of domestic items relief if the property is residential and the carpets were provided for tenant use.

Example 5: Legal fees chasing rent arrears in London

A landlord incurs solicitors' fees to pursue rent arrears and possession.

These costs are normally revenue in nature and deductible, because they arise from managing the rental business rather than acquiring or disposing of the property.

A simple checklist before you claim an expense

• Did the expense arise wholly and exclusively for the rental business?

• Is it a day-to-day running cost rather than a capital improvement?

• If it is a replacement, does it replace an existing item rather than furnish the property for the first time?

• Does any part of the cost relate to private use?

• Do you have an invoice, receipt or clear bank evidence?

• Could you explain the business purpose of the cost in one sentence?

• If it relates to finance costs, are you applying the correct mortgage interest relief rules?

• If the property was newly acquired, could HMRC argue the work was part of making it fit to let?

Company landlords and other special cases

This article is mainly aimed at the ordinary UK landlord taxed on property income personally, because that is where confusion is most common.

But structure matters.

Limited companies generally calculate profits under corporation tax rules, and finance cost treatment can differ materially from the rules for individual landlords.

Joint ownership also adds complexity, especially for spouses and civil partners, where beneficial ownership and Form 17 issues may arise in some cases.

Non-resident landlords, commercial property owners, and those with mixed residential and commercial portfolios may also face different treatment.

That does not change the main principle: you still need to distinguish a revenue expense from a capital one and keep proper records.

But the tax outcome can differ enough that generic advice from landlord forums often misleads.

Final practical approach for landlords

The safest way to manage allowable expenses is to think like an investigator rather than a claimant.

For each cost, ask what the spending actually did, whether it belongs to the ongoing running of the let, and whether you have evidence.

If the expense improves, enlarges or creates something enduring, assume it is more likely capital until shown otherwise.

If it simply keeps the property in rentable condition, it is more likely to be allowable against income.

For many landlords, the most valuable habit is keeping clean records throughout the year rather than trying to reconstruct everything before the 31 January filing deadline.

Separate repairs from improvements as you go.

Flag anything pre-letting.

Note which expenses contain private use.

Track finance costs separately from other deductions.

And if a bill is unusually large, ask whether it belongs in the rental income calculation at all or whether it is really a capital cost for future Capital Gains Tax purposes.

Done properly, allowable expenses reduce tax without straying beyond HMRC's rules.

Done carelessly, they create avoidable tax, weak records and unnecessary risk.

The difference is usually not in the law itself, but in how carefully the landlord applies it.
