Bathroom Extractor Fan
I want to replace my existing extractor fan with one which has a delayed motor - if you know what I mean.
Is it a simply a matter of disconnecting the wiring, removing the old fan, and reconnecting to the new fan or is it more complicated ?
Thanks.

Your fan probably has three wires (switched live/neutral/earth.) You'll need a fourth (permanent live.)
How easy it is to bring in the permanent live depends entirely on how your lighting circuit is set up.
Assuming your fan comes on with the light switch, the usual thing is to run a wire from the ceiling light back to the fan. Or, better still, remove the existing "twin & earth" cable and replace it with a "three core & earth"

Yep, BS is right on the button, as always. I should have said that a new cable should run from source to fan VIA the isolator switch.
New cable, plus location of work (bathroom) makes it notifiable........ and must include RCD protection.
All in all, better to have a Part P registered electrician do this. All kosher then :o)
