Help with wiring LED mirror in zone 2

[Beau]

Morning all

 

I cant get hold of my electrician at present so hope you can help. We have a zone 2 bathroom mirror that needs a power supply. I realise this will come from the lighting circuit but dont know if it needs an isolation switch, fused spur or something else. The lighting is on a new RCD protected circuit and I can have connection outside of the room the other side of the stud wall. I'm keen to get the wiring in place as I want to board up the stud wall ready for the plasterer. I should add my sparky is pretty hands off and is happy for me to do all the donkey work as long as I get it right haha. Thanks

I just did this - took a spur from a socket in an adjoining bedroom, to a fused switch in the vanity unit under the sink, then fed the wire up to a blank plated box behind the mirror.

I wired mine to the ceiling light which uses a switch outside. But mine is just a light not a shaver socket or USB phone charger etc.

For the time being I have just run a conduit from the back of the mirror to the light switch and fan isolator in the bedroom. If it needs a switch/fuse/other the sparky can add one later
