Bathroom Lighting with Extract Fan

[chrisdicko]

Someone I know wanted to put some new spot lights in his bathroom, so decided to do it himself, he started the job, but doesnt want to finish it and has asked me to. I work in heavy industry as an electrician, so arent too familiar with dosestic setups, but ive wired plenty of lights and sockets up etc (his new lights are fine for Zone 1 as well)

Anyway, there isnt much access at all, but this seems to be the current setup:

Should the fan really be running off the same circuit as the light fitting? It definately is as I tested the continity.

If thats fine, is it then safe to do the following?

The fan should be supplied from the lighting circuit. See the Wiki here: electrics:lighting:fan

The fan should have an isolator. This might affect which of the lights you take the switched live from. Most fans also require a permanent live so they can continue running on a timer after the light is switched off.

Are you familiar with the law concerning notifiable domestic electrical work?

Thanks Tim, there doesnt seem to be any isolator for it, and it isnt aon a timer, just turn off when the light switch turns off. So really, there shouldnt be a problem adding the extra two lights as shown in the diagram?

ban-all-sheds: Yeah, I know the score But I'll admit Im not the most experienced when it comes to domestic, so thought I'd ask here

If it's not a timed-overrun fan, and therefore doesn't have a permanent live supply it doesn't need an isolator.
