Does any one else think there should be a law as what should be done with shower cables when there is a loft conversion being done? I ask because i have just been asked to replace a shower(9kw) with a 9.5kw,cable is 6.mm and there is no way on earth a new cable can be run without ripping up all the flooring upstairs.I know what some will say but i have advised to go for a 8.5kw.
