I'm selling (or tying to sell) my flat. It has a small internal kitchen that was there when I bought it. I put in a suspended pine ceiling, and new kitchen units. The doorway is into the hall but there's no door, never has been. Buyer's surveyor says that due to building regulations I have to fit a fire door and fireproof the ceiling. Also says extractor fan is a bathroom fan and must be replaced with a kitchen one (think it may be wider diameter, may be a problem). Also says I have to sort the plumbing as there's a gurgling noise when water drains down sink (water flows freely, not sure if minor blockage or venting problem).
Do I really HAVE to do all of this ?
