Any idea how to remove this from the bathroom ceiling?

[lucysmam]

So I can straighten up, or replace, the spring in it?

I thought it'd either turn, or pull off, like the rest, but it doesn't

It's like it's superglued to the bloody ceiling!

Hopeful bump :)

Slide a sharp knife around the base if it's been stuck in with paint?

I've tried that, this morning, & wondered about just keeping scraping at it 🤷‍♀️

Remove the fuse from the consumer unit, so you have isolated the electricity to the fitment. If it’s broken you’ll probably need a new one, they’re quite cheap.
Once isolated you can use some force to remove it, pliers, hammer, whatever.

I thought the big white but unscrewed from a base normally but that does look old.

What are you trying to do? Replace the pull cord? Once it has been isolated you may have to smash it off. ( my electrician did this). It could have yrs of paint/and or plaster around it, keeping it stuck rigid. You will then need to make the exposed wires safe immediately after.

As a side note , the mould on the ceiling is shocking. I suspect no insulation behind the ceiling or a leaky roof or both. Room also needs ventilation. Wear a mask
when removing that light fitting as mould spores will be disrupted and airborne.

Is the ceiling artexed? I cannot see from photo. If so, you will need a professional due to possible asbestos in the artex. I personally would not use that light source until damp/ceiling issue resolved. I suspect ceiling may need to come down.
