Wiring in a shaver socket
Checking where to run the wires whilst the studs are only covered on one
side. DIYnot says "Shaver sockets can be install a shaver socket either by connecting to a ring main with a junction box (see Adding a spur to a ring circuit from a junction box) or from an earthed lighting socket. The spur from the ring main must be fitted with a 3amp fused connection unit before connecting to the shaver socket (see Fitting a Fused Connection unit). The fused connection unit should never be installed in the bathroom. Connection from a lighting circuit can be made directly, but must be earthed. " Firstly, is this up to date? If so, it seems I have two simple options for the upstairs bathroom (1) Drop a cable down from the loft which comes off the upstairs lighting circuit (2) Spur off the upstairs ring main and put the fused connection unit in the wall outside the bathroom. Going off the lighting seems cheaper and simpler. What are the downsides? Cheers Dave R -- No plan survives contact with the enemy.

Many bathroom lights have shaver sockets built in. [Some of these are only live when the light is on - which is a pain if you want to leave things like electric toothbrushes charging.

(I had to re-engineer mine!)] Work will be Part P compliant and signed off. At the moment I am just doing remedial wiring to move sockets and remove ceiling lights. However I will probably be running cables into walls prior to plastering for later checking/certification. Makes no sense to take half a day of an electricians time for trivial tasks. I will leave the major new stuff to the sparky - not because I couldn't do it but because I couldn't do it quickly. -- No plan survives contact with the enemy.

At the moment I charge the toothbrush beside the bed. However it is neater and easier to have it by the wash basin -- No plan survives contact with the enemy.

Also you need give some consideration to supplementary equipotential bonding - if your shaver socket is introducing the earth of a new circuit in the bathroom, and the wiring is not already to the 17th edition standard of having RCD protection on all circuits and main eq binding to spec, then the earth of the new circuit will need including into the EQ binding in the bathroom.

Thanks, as usual :-) The whole downstairs back is being ripped out and redone so we will be getting a brand new CU and everything checked and tested. Major new works to be done by a pro - I'm just clearting back redundant circuits and running in wires ahead of the plasterers to save calling out the pro sparky for little bits of jobs. -- No plan survives contact with the enemy.
