Could anyone please advise me how to wire an extractor fan with run-on
timer in a bathroom? It needs to be wired into a wall mounted light.
The instructions say that switched live, permanent live and 3 AMP
double pole fused spur are needed. The pull cord switch and the wall
light are run from a junction box in the loft. I'm a complete amateur
so please be as detailed and descriptive as possible.

Cheers!
