ours was on a fuse board not rcd so that was changed, the bath room light was wrong, there were 3 old round pin sockets that whilst dead have been removed, every light switch has been opened and new earth has been put in from the bath room to down stairs and both the gas and water have been rebonded with heavier cable. this last will however need redoing as for some reason they ziptied the new wire to the main hot water feed for upstairs which as you mght think gets well hot. so now we have holes in ceilings and pipe boxes and every switch to reset and tuch in. oh and the cupboard door for the cu no longer fits so i need to make a new one of them too. thing is it's not that i mind what they have done as i need that to comply it is having to redo finished work that bites.
