Switching a switched live?

[Jonny spark]

Hi. Looking at installing an extractor fan and spot lights for the new bathroom. Her indoors doesn't want the fan on with the lights and wants the spots to be dimmers.

Now, there are only switched lives at both the rose and the light switch and i can't access above the ceiling to try and find the jb with a permanent live.

I realise it's not safe to take the live direct for the shower circuit but is it ok to use the switched live from the lights and switch that? Not ideal i know but would just mean the fan would only run when lights are on and the switch is on.
Also if this is possible can you get switches which have 1 gang dim and 1 normal 1 way? Or should i get a seperate pull?
While i'm asking are 240v spots ok for bathroom as the low volt transformers are always going on the kitchen ones.

Cheers.

Surely there must be a permanent live at the light switch ?

Yes, you could use a grid switch, presuming this is outside the bathroom.
You will need a DP switch in one gang, a fuse in another, (for the fan) and the dimmer for lights in a third.

Yes, providing in correct zone and appropriately IP rated.

You can get dimmers which have two outputs - one full load and one variable. I've never bought one, but come across them in houses from time to time. Check that your fan is rated to run on 6A.

Hi thanks for the response.
Realised my mistake ref the permanent live and the switch laying in bed last night! Bit embarassing but nevermind. Not an electric ian anyway actually.
Probably easier to put the fan on a seperate fused pull switch then? I wasn't sure whether the fan needed fusing seperately as i have seen them on normal switches off the lighting circuit breaker only.

Well maybe you know the reality, but you haven't disclosed it here.

Electric Alan?

Easier than what? You're not making any sense man!

Are you still unsure?

You have a faulty woman. I recommend you exchange her for a more sensible one.
