Do void periods between tenants affect what I can claim?

By James Fitzpatrick · Fitzpatrick Co · Brighton & Hove · 3 min read · Last reviewed 29 September 2026

Yes. A void between tenants does not stop you claiming genuine running costs, as long as the property is being marketed or prepared for letting. Insurance, utilities, agent fees and repairs remain allowable. Improvements are capital, and a long empty spell with no plan to re-let puts the deduction at risk.

What you can claim during a void

Mortgage interest

An individual landlord cannot deduct mortgage interest from rent. Instead there is a 20% tax credit on residential finance costs, and it still applies through a void because the interest is still being paid. A limited company deducts interest in full.

Repairs or improvements

Putting things back to how they were is a repair and is deducted from rent. Replacing a worn-out carpet or appliance with a similar one is normally fine too. Adding something new, such as an extension or turning a box room into a bedroom, is a capital improvement. It is not deducted from rent, but it can reduce a Capital Gains Tax bill when you sell.

When a void goes on too long

The property has to remain part of your letting business. If it is empty with no marketing, being renovated for sale, or used by you or your family, the letting may have stopped and the deductions can go with it.

Worked example

A Hove flat let at £1,250 a month is empty for two months. You pay £45 insurance, £110 utilities, £600 to the agent for a new tenant, £90 for cleaning, £520 to repaint and £680 to replace a worn carpet. All six are allowable, £2,045 in total.

If you also spend £6,500 turning the box room into a bedroom, that £6,500 is an improvement. It is not deducted from your rent.

What to do

  1. Keep dated evidence that the property was advertised or with an agent.
  2. Ask contractors to split invoices between repairs and improvements.
  3. Record the start and end date of every void.
  4. If a void runs past a few months, ask us before you claim.

Common questions

Frequently asked questions

Do void periods between tenants affect what I can claim?
Yes. A void between tenants does not stop you claiming genuine running costs, as long as the property is being marketed or prepared for letting. Insurance, utilities, agent fees and repairs remain allowable. Improvements are capital, and a long empty spell with no plan to re-let puts the deduction at risk.
Can I claim council tax while my rental is empty?
Yes, if you are the one liable for it and the property is available for letting. Keep the bills with your records.
Do I pay tax on rent I never received?
If you use the cash basis, which is the default for most individual landlords, you are taxed only on rent you actually receive. Under the accruals basis, unpaid rent may have to be reported unless it is written off.
Is replacing an old kitchen a repair or an improvement?
Replacing like for like is normally a repair. Upgrading to something clearly better, or adding a new feature, is more likely capital. It depends on what was there before, so keep the old and new specifications.
