I am thinking of giving our bathroom a revamp but have hit a mental stumbling block over the electrics.
Currently the bathroom has a single pendant light and a SELV extractor fan with transformer in the loft, both running off the upstairs lighting circuit which has no RCD protection at the CU. The rest of the upstairs lights are on the same circuit, and the upstairs sockets are on their own circuit again without RCD protection at the CU. The CU has RCD protection for some circuits but not these.
I would like to replace the bathroom light with 4 or 5 downlighters, possibly add a 2nd extractor fan, and replace the radiator with 2 towel rails that would run off the heating but also electricity when heating is off.
For this work I will need to get a Part P electrician in as it's all notifiable, however I would first like to get my head around the best solution that would minimise decor disruption to other rooms and possibly allow me to put wiring in place for the electrician to just check and then connect up. In my experience, tradesmen want the quickest/easiest solution for them, which is not necessarily the best solution for me, and so I prefer to go into battle fully armed or even spell out exactly what I want.
With that in mind, what is the best solution with minimal disruption? My current thought is that a new circuit for the bathroom could be added to the CU on the RCD protected side - this has a relatively easy path from CU to spare bedroom, then lift carpets to run into bathroom, where the radiators can be fed by it. In this scenario could the lights also run off the same circuit, with/without FCU? Wiring would need to run up the bathroom wall to the ceiling, to avoid chasing out new decor in other rooms. Also do radiators need isolating switches outside the bathroom? I could end up with a cockpit of switches outside the bathroom door, which I want to avoid.
