Landlord Repairs vs Improvements: What You Can Deduct
Landlord repairs vs improvements — which property costs are tax-deductible? See HMRC rules, real examples, and how to categorise your expenses correctly.
Key Actions
- Review your property expenses and categorise each as a repair or improvement
- Keep invoices with descriptions of work done to support your categorisation
- Photograph the condition of items before replacement to evidence like-for-like
- Check if any upgrades qualify as a repair using the nearest modern equivalent test
- Note the cost of an equivalent replacement separately if you choose to upgrade
Landlord repairs vs improvements is one of the most common areas of confusion — and HMRC challenge — for UK rental property owners. Repairs to your rental property are tax-deductible as a revenue expense, reducing your taxable rental profit. Improvements are capital expenditure and cannot be deducted from rental income.
Getting the categorisation right matters. Claiming an improvement as a repair can trigger an HMRC enquiry and a tax adjustment. Missing a legitimate repair means you pay more tax than necessary. This guide explains HMRC's rules, walks through the grey areas, and provides practical examples to help you categorise your property costs correctly.
What Is the Difference Between Repairs and Improvements?
A repair restores something to its previous condition — it puts right wear and tear, damage, or deterioration. Repairs are allowable expenses that reduce your taxable rental profit.
An improvement enhances the property beyond its original condition — it adds something new, upgrades quality, or increases the property's value or functionality. Improvements are capital expenditure and cannot be deducted from rental income.
| Repair (deductible) | Improvement (not deductible) | |
|---|---|---|
| Purpose | Restores to original condition | Enhances beyond original condition |
| Tax treatment | Revenue expense — deducted from rental income | Capital expenditure — not deductible |
| Effect on property | Maintains existing value | Adds value or functionality |
| Examples | Fixing a leak, repainting, replacing broken items | Extensions, new installations, quality upgrades |
What Counts as a Tax-Deductible Repair
A repair restores an asset to its original condition, sometimes by replacing parts of it. The key test is whether you're putting the property back to the state it was in before the damage, wear, or deterioration occurred.
Common allowable repairs:
- Replacing roof tiles blown off in a storm
- Fixing a leaking pipe or tap
- Repainting walls and woodwork between tenants
- Replastering cracked or damaged walls
- Replacing a broken boiler with a similar model
- Fixing or replacing a broken window
- Repairing damaged floorboards
- Patching a pothole in a driveway
- Replacing a broken extractor fan
- Re-tiling a bathroom where tiles have cracked
The replacement test: You can replace parts of the property — or even entire elements like a kitchen or bathroom — and still claim a repair, provided the replacement is of a similar standard to the original.
What Counts as a Capital Improvement
An improvement goes beyond the original condition. You're adding something that wasn't there before, or upgrading to a materially higher standard.
Common non-deductible improvements:
- Building an extension or conservatory
- Converting a loft into a bedroom
- Installing central heating where there was none before
- Adding a security alarm system for the first time
- Fitting a driveway where there was no hard standing
- Adding a new bathroom where only one existed
- Installing a new kitchen where the property previously had no fitted kitchen
The addition test: If you're adding something entirely new to the property — rather than replacing or restoring something that already existed — it's an improvement.
HMRC's Nearest Modern Equivalent Test for Property Upgrades
Many property works don't fit neatly into one category. HMRC applies a nearest modern equivalent test for borderline cases.
Replacing with Modern Equivalents
If you replace something with the nearest modern equivalent, this counts as a repair — even if the modern version is technically better than the original.
Examples that count as repairs:
- Replacing single-glazed windows with double glazing (modern standard, incidental improvement)
- Replacing a conventional boiler with a condensing boiler (nearest equivalent now available)
- Replacing copper pipes with plastic ones (standard modern material)
- Replacing a basic electric shower with a similar-specification electric shower
The improvement is incidental — the primary purpose is replacing a worn-out or broken item, not upgrading the property.
Upgrading Beyond the Nearest Equivalent
If you deliberately choose a higher specification than necessary, the extra cost is an improvement.
Example: Sarah replaces the kitchen in her rental flat. The old kitchen had basic laminate worktops and freestanding appliances.
| Scenario | Tax treatment |
|---|---|
| Installs new basic laminate worktops and similar appliances | Repair — like-for-like replacement |
| Installs granite worktops and integrated appliances | Partial improvement — the cost of a basic equivalent kitchen is a repair; the additional cost of the upgrade is an improvement |
If the total cost is £8,000 and a like-for-like replacement would have cost £4,500, Sarah can claim £4,500 as a repair. The remaining £3,500 is capital expenditure.
Replacing an Entire Element
You can replace an entire element of a property (an entire roof, all the windows, a complete kitchen) and claim it as a repair — provided you're replacing like with like.
Example: James replaces the entire roof on his rental property because it's reached the end of its useful life. The new roof is of similar quality and materials. This is a repair — he's restoring the property to its original condition, not improving it.
If James added a dormer window during the re-roofing, the dormer element would be an improvement. The roof replacement itself remains a repair.
Repairs vs Improvements: Common Scenarios for Landlords
| Work done | Repair or improvement? | Reasoning |
|---|---|---|
| Replacing a broken boiler with a similar model | Repair | Restoring to previous condition |
| Replacing a broken boiler with a smart system and underfloor heating | Improvement (partially) | Underfloor heating is new; smart system may exceed nearest equivalent |
| Repainting and re-carpeting between tenants | Repair | Restoring to lettable condition |
| Replacing synthetic carpet with wool carpet | Improvement (partially) | Only the cost of a synthetic equivalent is deductible |
| Rewiring a property to current safety standards | Repair | Maintaining the existing electrical system |
| Fitting a new kitchen where the property had no fitted kitchen | Improvement | Adding something that didn't exist before |
| Replacing an old fitted kitchen with one of similar quality | Repair | Like-for-like replacement |
| Damp-proofing treatment | Repair | Restoring the property's condition |
| Adding an en-suite bathroom | Improvement | New addition to the property |
| Replacing a flat roof with a pitched roof | Improvement | Changes the character of the property |
How Repairs and Improvements Affect Your Tax Bill
The financial difference can be significant, especially at higher tax rates.
Example: Tom is a higher-rate taxpayer (40%) with £3,000 in property work costs.
| If categorised as... | Tax effect |
|---|---|
| Repair (deductible) | Reduces taxable profit by £3,000 → saves £1,200 in tax |
| Improvement (capital) | No deduction from rental income → saves £0 now |
Improvements aren't lost forever — they're added to the property's base cost for Capital Gains Tax purposes when you sell. But the tax benefit comes much later and only if the property has increased in value.
Record Keeping to Support Your Repair and Improvement Claims
Good records are your defence if HMRC queries a claim. For each piece of work:
- Get a detailed invoice — it should describe the work done, not just state "plumbing work" or "kitchen"
- Photograph before and after — this evidences the condition before the work and shows it was restoration, not enhancement
- Note the specification — record what was there before and what replaced it
- Separate costs on mixed projects — if work includes both repair and improvement elements, ask your contractor to itemise them separately on the invoice
- Keep records for at least 5 years after the 31 January filing deadline for that tax year
Under Making Tax Digital (from April 2026 for qualifying income over £50,000), these records need to be kept digitally. Our landlord records checklist covers what to keep in detail.
Frequently Asked Questions
Can I claim a full kitchen replacement as a repair?
Yes, if you're replacing the existing kitchen with one of a similar standard. The key is like-for-like. If the old kitchen had basic units and you install similar basic units, it's a repair. If you upgrade to a higher specification, only the cost of a similar replacement is deductible — the upgrade portion is capital expenditure.
Is replacing single glazing with double glazing a repair or improvement?
HMRC generally treats this as a repair. Double glazing is the nearest modern equivalent to single glazing — you can no longer buy single-glazed units as standard. The improvement (better insulation) is incidental to the replacement of worn-out windows.
What happens to improvement costs at tax time?
Improvements cannot be deducted from rental income, but they are added to the property's base cost when calculating Capital Gains Tax on a future sale. This reduces your CGT liability when you sell. Keep records of all improvement costs for this reason.
Can I claim for work done before the first tenant moves in?
Pre-letting repairs to make the property suitable for letting are generally deductible — as long as they would have been allowable if the property were already let. However, initial improvements to bring the property up to a lettable standard (such as fitting a kitchen or bathroom for the first time) are capital expenditure. See our guide on allowable landlord expenses for more on pre-letting costs.
