that is a timer fan that requires a permanent live and a switched one and neutral the feed up is just a switched one so someone has linked it to make it run

Soo question is can you get a new 3c +e wire down to the fan or up from it then you could use the existing wiring and a switch live from the light to save chasing down to the switch?
Humidity version looks like it can operate with just live and neutral!

Fan is also in Zone 1, so i think a standard Manrose fan is not correct anyway?

most are humidity and timer requiring 3 cables as u say you could get a switched live from the light
not seen any drawings just for 2

Looking at the photos I may well be able to get a cable from the light to the fan position with minimal/no damage...So make the feed from the switch to the fan a permanent live and then get a switched live from the light?

You are correct @brightspark my mistake I am two speckled hens down after a very warm day in a factory with no air con!

Is it on the ceiling? Might well not be in zone.
Can't see any solution past pulling another cable sadly.

Nicking a switched live out of a light would save a lot of faff. Do fans need an isolator switch?
I'm sure i remember having to put one in on a property after an EICR flagged up there wasn't one.

If you're really stuffed for cabling, you can get a widget that fires a relay, with a radio signal. So the relay would live in (or near) the fan and provide a switched live when the remote control tells it to.
However, if you're thinking of fitting a humidity controlled one, you could just wire that in and let the fan turn on/off when it wants to. It'll inevitably fire when the shower is on and overrun too. Not so effective with "odours" though. Need a poomidistat for that.

yes and no .if its on the same floor as the distribution board and fitted with an mcb no that is the isolator for the circuit .. if on a diffrent floor yes it is needed an odd one but true
