Bathroom Extractor fan

Hi
Our bathroom has extractor fan with no timer function,and hence minimal mold is a problem
If we bring in a sparky is it easy to wire up to install an extractor fan with timer function.
We dont have any isolator switch outside the bathroom.
Many Thanks

    I'd ensure you get one with a humidstat to ensure it runs for long enough to deal with any moisture.

    I don't see how the wiring would need to be any different

    Fans with a run on timer need 3 wires to the fan -  "Permanent" Live, Switched Live and Neutral.

    If the current fan goes on and off immediately with the light switch there's almost certainly no Permanent Live avaliable to the Fan currently and will need to be added together with an isolation switch outside the bathroom. It's still an easy job for any sparky.

    11fr, what access is there to the ceiling above? As Nearly says, almost certainly your fan will require a permanent live added, so it can keep on running after the light switch has been turned off.
    There's a chance that this can be obtained from the light fitting, depending on how that was wired. Is the light also on the ceiling? And is it close to the fan?
    I'm not sure what the regs say about this, tho' - I always thought a fan required its own isolating switch, a 3-pole type if a timer type.
    Have you looked in cupboards and similar to see if there is an isolator in there? High up on the wall outside, perhaps? It usually looks like a wide light switch!

    Ours did not have an isolation switch or timer but the electrician added the switch and replace the fan to a better one after we moved in. No idea how he did it without causing any damage, but now there is a switch on the wall near the light switch where previously there was nothing.

    There is a chance that the current fan has a timer function, and it just has not been wired in.
