Hi all, first post, please be gentle 
Iv been involved in a bathroom refurb, nothing major, moving a light fitting and switch.
My problem came when it was announced during second fix a bathroom fan was also to be installed with isolator. I've managed to pick up a permanent & switched live (using 2core & earth) from the light switch to a 3pole isolator mounted above, then owards to the lighting jb for a neutral, 3core & earth from jb to extractor unit.
Despite best efforts (and much wasted time) i could not get two 3core & earths to where the isolator is situated (as i would usually do) without causing significant damage to finished walls.
So, in short, my qestion is, is it acceptable to only switch the line conductors and not neutral for a bathroom extractor? The earthing system is TN.
As far as i can tell, im working within regs, but any advice / guidance would be appreciated!
