Hi,
Is there a roof space above, or is there another floor to your house?

Another floor not sure if it’s the bedroom or adjacent bathroom.

Ceiling was also plastered before new kitchen was installed a few weeks before
So probably not a condensation problem.
There could be a small leak from the bathroom / C/H, that is tracking along the new wires to the heat alarm?

Not mains wired I don’t think interconnecting battery
Ok, odd!
Then could it be grease marks from a very grubby installer!?
If you can, take the alarm down and double check there's no wiring behind!
The ceiling might just need a clean and the paint touched up.
Are there any marks around other items he installed - it may only show up like this here, because of the moisture/grease in the kitchen?

No. We’ll have a look.
Was the kitchen ceiling just skimmed with plaster. Could be grease coming through from old plaster.May need to seal ceiling and paint again.

Wonder if this is the case. Heat alarm removed no discolouration on that. No leak under bath. When I wipe the marks with soap water they come off.
You may need to use something like zinsser stain block sealer on your ceiling as grease will keep coming through.
