Is it ok to run an extractor fan in a bathroom in Twin & Earth if client wants it Independant from the bathroom lighting?

[jamest4541]

Basically, the room in which i am talking about has a twin and earth feed from a switch downstairs which was originally for an outside light. The client would like to take that feed and use it for an extractor fan in the new converted bathroom. The cable used is twin and earth. If i were to make the downstairs switch (which was for the outside light) the isolator switch for the fan (as its not a good idea to have it inside the bathroom) could i use the twin and earth for the fan directly, as he wants it independent from the lights in the bathroom therefore not requiring the need of a switch line?

Also, there is no access above the ceiling, only under floor boards, and the cable to run up to the extractor fan has to be run in surface PVC trunking.

Any help would be much appreciated!

Sounds all rather odd, you would have to go downstairs to control it. Why wasn't it done on the bathroom conversion.

The bathroom hasn't been fully converted yet (it was originally a bedroom) so all wall sockets are going to be looped out aswell. Despite the fact that he would have to control it from downstairs is there any other issues that may occur from doing that?

Notification with Part P may be problematic, best get an Electrician involved mate. if you're not sure.

RCD protection maybe

Also, you say the other sockets are going to be looped out? Could you elaborate a little?

ok thanks, i was only after a second opinion from someone with experience of extractor fans just to tell him really. as he asked me if it were possible and i didnt see any other issues occuring apart from the fact that he would have to turn it off and on himself?

sorry yes, there are 2 double sockets on the walls which obviously will be taken out and the cables connected in junction boxes to complete the ring. under the floor boards that is

Surely if the 'feed' from the outside light switch is used to operate the fan, and is going to be used for the lights....then the lights wont work if the fan is off.....unless there is already a supply for the lights?? If there is then why dont you use that for the fan via a pullswitch in the bathroom still independent from the light switch?
Controlling a fan from downstairs?...really?

I’m well confused here. Why not just take it from the bathroom lights ?
Nothing to say isolators must be outside the bathroom either

there is no reason not to use an existing switch as he wants. the convenience/inconvenience of doing this would be his concern.
