as has been said before this will not happen.I can't see what the problem is whether I get an electrician in at the beginning, now or at the end, the work will be done, it will be safe and it will meet the current regulations
I suppose you paint/wallpaper the walls before the ceiling as well then.And it doesn't matter about when the ceiling goes up, done my mothers house the same way 16 years ago and everything is ok
riveralt, I can't see what your problem is ... what will not happen ?
and why the silly comment about the ceiling ?
I've had to replace many ceilings on the renovations I've done, never had a problem with any of them, I just get someone in to skim it ( and usually the walls) afterwards .
