Default New timer extract fan in bathroom... 3 pole isolation required?

Regardless of the answer, have you thought about just having a separate
pull switch for the fan? That means you don't need an isolator switch
and don't have the fan coming-on when you have a pee in the middle of
the night. I did that (it also controlled a single light over the
shower) in the previous house and all were pleased.

I notice most bathroom fan isolators are installed above the entrance. As my intention is to fit an inline fan in the loft is it acceptable to place the isolator beside the unit, it is just to avoid more wall chasing in an awkward place?

I think the regs say it has to all be done that way.

If you can't easily get at the fan to work on it without coming across
the isolator I would think it is fully compliant. I am not an expert
though.

That is what I did - prefer to have the switch inv view when cleaning
the fan so someone else can't put the power back on.

Mine is in the void of the suspended ceiling, right by the in-line fan
and within inches of the hatch that is just big enough to do the work
from standing in the cupboard below.

Normally yes.

Naughty me. When I did this 30 plus years ago for an adjacent shower/loo
I just wired the fan to the two lights with a simple single pole light
switch. This is a fan inside the duct so not readily accessible.

In your case next to the fan in the loft would be the preferred choice.

In fact I fitted on just inside a loft hatch a couple of months ago in a
HMO for a wall mounted fan. This was a super quiet all time trickle with
boost when the lights go on.

The owner did want the Polish and Moldavians messing with it.
