    Do bathroom extractor fans need to have isolation switches for building control?

    Yup, think it's building regs, rather than lecky regs?

    Building regs Part F (ventilation) will specify the extract rate and any over-run requirements.
    Building regs Part P will determine the standard that the electrics should be installed to. That says BS7671 is the recomended way to go.
    Also following the manufacturers instructions will be included.

    ...so it's best to run your whole bathroom lighting/fan ctt off it's own fcu with a 3a fuse in it. I mean so long as your bathroom isn't wanting the Blackpool illuminations in it.

    Now why didn't I think of that...bought an FCU and 3 pole isolator for the fan, but could just put the whole lot on the FCU :) 3 pole isolator ain't cheap either...can return it to our hosts.
