The rent-a-room scheme only applies to the letting of furnished rooms for residential purposes in the taxpayer's home. If rooms are let as an office or for any other business purpose a claim cannot be made for rent-a-room relief.
It is highly unlikely that you would be able to claim this relief if the extension is a self-contained unit. HM Revenue & Customs would need to be satisfied that the extension formed part of your main residence and was not a separate residence. They would generally only allow a claim where a property has been divided if the division was only a temporary one. This would be determined by reviewing whether structural alterations would be necessary to reverse the division and how long the residence has been divided into separate accommodation. Other factors that will be considered are whether or not the apartment has a separate postal address and door entry and whether it is metered separately for mains services.
If you are uncertain as to whether rent-a-room relief will be available on your property, you should seek advice from your local TaxAssist Accountant.
