thanks for the replies. will go and take some pics and come back bit later & register. I think they started tiling near the floor - i remember seeing some sort of wooden baton going around the room and they started tiling above that. The ceiling used to have wooden cladding so I asked them to take it off and replaster / skim the ceiling.
There has been a number of people in there working together - plasterer / tiler / plumber headed up by a guy that was recommended to us. The tiles are level so I presume they did bodge job by not ensuring ceiling was level before tiling. I agree that lowering ceiling is best route - although sounds like a hassle as it has been painted and spotlights are in. Do I have any other options? Someone suggested using the same tile as a border at the top of the wall.
Or you could get him back and get him to do it properly, why should you have the cost of lowering the ceiling, it aint going to be cheap having a false ceiling put in and plastered.
