I've attached the relevant information from the 18th which will hopefully clear this up for you. Items may appear to be in a zone but in reality it depends on the height of your ceiling. To put it simply, 240v is not allowed in the zones. However, from the sounds of it, whoever fitted the fan bought the cheapest one from Screwfix.
But to be extra super duper safe, just stick it on an RCD.
Thanks for this. Ive attached a picture to show you all why i was concerned/confused.
I will be removing the fan as its coming away from the ceiling anyway and will replace it with a selv unit with a humidistat anyway for my own piece of mind.
Edit :- measured the floor to ceiling and its 2.35m
When we moved in this shower was in a right state, downlights falling from ceiling, and water leaking from seemingly everywhere and its using a saniflow shower pump for the waste which is located behind the shower (also leaking)
Turns out that the cubicle had been installed and not siliconed in so water was getting out the sides also underneath the screen door with a missing trim and none of the floor is grouted properly.
The saniflow unit had been duct taped to the floor boards and was leaking as the seals were perished (he tried to fix this with more duct tape)
And that was before all the wiring atrocities found in the loft.
Stil we knew we were inheriting a “done it myself mate” house so im working my way thru it as i go.
