Bathroom Fan - Isolator Switch?

feral

Hi All

I am in the process of getting quotes to fit a bathroom fan as part of my bathroom refit, I have received conflicting advice though from contractors:

- one of the contractors said I will need an isolator switch placed outside the bathroom
- two have said I don't need one
- another has said I need one, but it is OK to place it within the bathroom so long as it is outside Zone 2 - he suggested next to the fan itself, high up on the wall

If it makes a difference the bathroom has a large window, but I still need a fan as condensation does build up, also it's nice to get rid of smells!

The fan I am having installed is the HIB Breeze with Timer fan (can't post a link, sorry)
Your thoughts are much appreciated

I thought you needed an isolator outside for both fans and electric showers

Isolator if fitted just needs to be outside zone 2.

My understanding is that a means of isolation is needed so the fan can be safely maintained. Your consumer unit/fuse box switch is a means of isolation and may be sufficient. I have read in several places that it depends on there being sufficient natural light in the room to be able to work with the power off (so there needs to be a decent sized window). If it's too dark without the light on then you need a way to isolate separate from the light.

If it's wired to come on with the light then some people like to have a separate means of isolation anyway so they can turn it off at night.

As TheCyclingProgrammer said. Not required by building regs.

But for the sake of a few extra quid I would always fit one.

My bathroom and en-suite fans used to come on with the lights...and it was very annoying at night.

They both now have double pole, pull cords fitted just inside the door so that they can be turned on and off as needed. The en-suite cord also operates the electric shower (handy as I always used to leave the shower turned on!).

Fit an isolator if you want but make sure it'll suit your needs or fit with how you use the room.
