3. The distinction: Improvements

By contrast, under the “repairs vs improvements tax treatment” heading, an improvement is instead capital expenditure.

It typically enhances the property’s value, extends its life, changes its character or adds a new function.

Examples of improvements include:

• Constructing an extension or loft conversion.

• Installing a brand-new kitchen of significantly higher spec (not like-for-like).

• Converting a garage into a living space or office.

When expenditure is capital in nature, you cannot deduct it as a normal expense for income tax purposes; relief is given differently (via capital allowances or reducing a later capital gain on disposal).

4. Why the correct classification matters — “repairs vs improvements tax treatment” in practice

Getting the classification right is crucial because if you mis-classify expenditure you may:

• lose the immediate tax relief you anticipated (if you incorrectly treat improvements as repairs),

• incur unexpected tax charges (for example on disposal if improvements weren’t properly recorded), or

• attract enquiries from HM Revenue & Customs about your claims.

For example, a landlord who treats a major refurbishment as a repair may find the deduction challenged and may have to restate profits, losing the relief and possibly facing penalties or interest.

5. Updated rules for tax year 2025/26 you need to know

When considering “repairs vs improvements tax treatment”, keep the following updated matters in mind for 2025/26:

• The threshold for the annual capital gains tax (CGT) exempt amount remains at £3,000 per person. The 2025/26 rates for residential property disposal are 18% for basic rate taxpayers and 24% for higher rate taxpayers. Taxfix+1

• Under the cash basis, if rental receipts are £150,000 or less, you may deduct both revenue and capital expenditure provided certain conditions are met (though capital rules still apply) — so classification remains important.

• Maintenance work that uses modern materials but remains broadly equivalent will still qualify as a repair, under the “repairs vs improvements tax treatment” rules.

• Landlords of furnished holiday lets (FHL) should be aware that favourable tax treatment for FHL properties is abolished from 6 April 2025. That change can affect your “repairs vs improvements tax treatment” considerations.

• For “integral features” (e.g., electrical systems, water systems) replacing more than 50% within 12 months may mean the cost is a capital improvement not a repair.

Always keep records of quotes, invoices, condition before and after, and the nature of the work (i.e., was it simply restoring or enhancing?) — this supports your treatment decisions.

7. Frequently Asked Questions (FAQ)

Q1: If I replace windows with better glazing, is it a repair or an improvement?
It depends on whether the replacement is broadly equivalent to the original (repair) or a significant upgrade (improvement). Under the “repairs vs improvements tax treatment” test, modernising from single glazing to upscale triple glazing may be improvement, while like-for-like may be repair.

Q2: Can I claim relief straight away if it’s an improvement?
No — if expenditure is capital (an improvement) you cannot deduct it as a repair expense against rental income. Relief arises via capital allowances (in certain cases) or by reducing capital gains when you sell.

Q3: What if I use the cash basis for my property business?
If your rental receipts are within the allowable threshold (e.g., £150,000 or less), you can often deduct both revenue and capital expenditure, provided it meets the criteria for property business expenditure. However classification under “repairs vs improvements tax treatment” is still necessary.

Q4: Do the “repairs vs improvements tax treatment” rules apply to furnished holiday lets (FHL)?
Yes — and importantly, from 6 April 2025 the favourable FHL tax regime is abolished. So landlords of former FHL properties should be particularly careful about how they treat their expenditure.

Q5: How should I keep records to support my treatment?
You should keep: quotes and invoices, photographs showing condition before and after, a description of the work and whether it restores or enhances, and details of the original asset. These records support your position under “repairs vs improvements tax treatment”.
