Bathroom fan wiring query (sorry!)

It's best to install a localised double pole isolator switch to a fan circuit for servicing purposes, and it isn't necessary to have a pull cord switch if the switching is being done from outside the bathroom where you don't have your hands in a wash basin full of water. So, yes, you can install a two gang switch outside the loo room to control the fan and lighting independently of each other, but it's best to have the live and neutral for the fan running through a double pole switch (5 amp rating should be enough) and install it either above or below the two gang switch before the supply carries on to the fan itself.

thats how you do it then>

fans are usually wired into the lighting circuit using 3 core cable and isolated using a fan isolator switch

I think it just assumes you are putting the switch in the bathroom, all of my fans are switched from a seperate wall switch outside, and it's to the regs.

Yes, you still need an isolator, no need for an FCU though, just a double pole isolator like an immersion heater switch will be fine. I usually use a TP fan isolator though, so it's got a label saying what it does.
