UK-wide. The rules on what is deductible are the same across the UK; only the tax rates differ.

Information, not tax advice. The general rule is that an expense must be incurred wholly and exclusively for the property business. Where a cost is partly personal, only the identifiable business proportion is claimable.

The short version

Since Section 24 removed mortgage interest from the expenses list, every remaining deduction is worth more than it used to be, because it is now the only thing reducing your taxable profit. The single line that decides most disputes is repair versus improvement: restoring something to its previous condition is a repair and comes off this year’s rent; making it better than it was is an improvement and waits until you sell, when it reduces the capital gain instead. Neither is lost — but one relieves at your income tax rate now and the other at your capital gains rate later.

Mortgage interest is deliberately absent. Since April 2020 it is not an expense at all — it goes through the 20% credit under Section 24.

What you cannot claim

  • Mortgage capital repayments. Only ever the interest, and now only as a credit.
  • Improvements. A new extension, a new conservatory, the first fitting of something that was not there.
  • Your own time and labour. You cannot invoice yourself.
  • Costs of buying or selling. Legal fees, survey, stamp duty and estate agent fees are capital costs — they reduce the gain when you sell.
  • Fines and penalties. Including licensing penalties and parking tickets.
  • The cost of the property itself, or of the land.
  • Personal expenses with only incidental business use.

Repair or improvement: the line that matters

The last row catches most people. Work done before the first letting, to bring a property up to standard, is normally treated as part of the acquisition cost rather than a deductible repair.

Nothing is wasted. An improvement is not a lost deduction — it is added to the base cost and reduces your capital gain when you sell. Which is why keeping the invoice for that extension for fifteen years genuinely matters.

The five HMRC challenges most

  1. Whole-property refurbishments dressed as repairs. A single large invoice covering a full renovation invites the question. Ask the contractor to itemise repair and improvement work separately at the time, not afterwards.
  2. Travel. Regular trips to a property near a holiday home, or mileage that implies more visits than a property could plausibly need. Keep a dated log with the purpose of each visit.
  3. Use of home and phone. Round-number apportionments with no working. A modest, evidenced claim survives; a large unexplained one does not.
  4. Pre-letting expenditure. Costs incurred before the property was first let, claimed as running costs. Expenses in the seven years before the business starts can qualify, but only if they would have been deductible had the business already been trading.
  5. Replacement of domestic items relief. Claiming the first purchase rather than a replacement, or claiming an upgrade in full. The relief covers a like-for-like replacement; if the new item is better, only the equivalent cost qualifies.

Records

Keep invoices, receipts, bank statements and your mileage log for at least six years after the tax year they relate to, and keep the capital ones indefinitely because you will need them at sale. If Making Tax Digital applies to you, the records must be digital and categorised as you go — which in practice ends the shoebox-in-January approach whether you liked it or not.

Can I claim a new kitchen?

If it replaces a worn kitchen at a similar standard, yes, as a repair. If it is a significant upgrade, the uplift is capital and waits until you sell.

Can I claim for my own labour?

No. You can claim materials, but not the value of your time.

Can I claim expenses during a void?

Yes, provided the property is genuinely available to let and you are actively trying to let it. Costs during a period you occupied it yourself are not claimable.

What is the property allowance?

A £1,000 allowance you can claim instead of actual expenses. Below £1,000 of gross rental income you need not declare it at all. For anyone with a mortgage, actual expenses are almost always worth more.

Can I claim expenses from before I let the property?

Potentially, for the seven years before the business began, but only where the cost would have been allowable if you had already been letting. Work to make the property lettable is usually capital instead.

Do I need receipts for everything?

Yes in practice. A claim you cannot evidence is a claim HMRC can remove, and the burden is on you.
