I have a long standing client who runs a cleaning business from home. He can have anywhere between 5 and 15 employees at any one time. We have a licence agreement in place as the homeowner charges the company to use his premises but the client now wants to claim for substantial property costs (£6,000 to allow more vans on his drive, to build a porch so employees don't keep coming into the house) which to my mind completely fails the wholly, exlusively and necessary test. He is adamant that the accounts should include these costs as he and his wife feel they have little privacy with employees feeling they can turn up at any time to discuss issues relating to their employment. The client is willing to deal with the fallout if this occurs. I acknowledge I am the agent but I have yet to be in a position where a client ignores my advice so blatantly. I don't want to walk away but my integrity is important to me. I'd be very grateful for some advice.
