Wiring electric 10mm cable from shower unit to consumer unit, I have managed to find a pretty good route without lifting any floor boards but the problem I have is that the electric cable would be about 2 inches away from a hot water pipe that goes into the boiler would this be okay and how far should i be to be safe? one more question would it be okay to run the cable through the boiler room? Also is it madatory to have the electric cable running from behind the wall or can I use a condiut or chase it
