I am currently redoing the bathroom in the house we just purchased. I am planning on installing: Mira Platinum Shower - 3A AKW D17 Waste Pump - 5A Illuminated mirror with shaver socket and demister There is already a fused circuit going into the bathroom to where I assume a power shower was but its now just a bare wire with the fuse pulled from the circuit where it ends in the airing cupboard next door to the bathroom. My question is, can I carry out any of the work wiring it up myself if I get it signed off by the council or does all of it have to be done by a sparky? I am planning on reusing the existing circuit for at least one of the devices though I guess I cant use it for all of them? There is also no RCD in the circuit (or the consumer unit) so I guess I will need to add one? I was thinking about one of these: http://www.screwfix.com/p/mk-sentry-4-way-rcd-shower-consumer-unit/42858 All off the wiring will be behind stud work and aquapanel. The internet seems to give conflicting information on whats allowed so any advice is greatly appreciated. Thanks, Tom.
