I have a client who wants to build a swimming pool in their home back garden. To generate some extra income they are looking into renting it out to swimming instructor businesses.
I am advising my client that the cost of building the swimming pool is not allowable. But once it is up and running the income and associated pool costs (apportioned at a reasonable business % usage) can be netted off and declared as income from land and property.
Can anyone point me in the direction of these particular HMRC rules / legislation please? I'd like to share this with my client alongside my advice.
