I have a client who lives in a reasonably large and old property with a barn attached. The barn was converted into accommodation some years ago but has only been used by visiting family and friends . He is considering letting it under AirBnB. The barn is self contained and there is a stipulation when planning permission for the conversion was given, that it cannot be sold seperately - it must be sold as one unit with the house.
Will the letting income qualify for Rent a Room relief?
