Thanks in advance

"Hello Wayne

So many variables to this question, me personally, sounds like the workmen have disturbed the ceiling due to moving around above it.

You need to find out firstly if it’s a lime mortar or plasterboard ceiling Wayne, you can usually tell by , if the cracks are in strait lines it’ll be board or more sporadic almost shaped like coastal lines, it be lime mortar.

Plasterboard I would rake out the crack and fill with easifil, rub down and paint.

Lime mortar ceilings are a bit more volatile they can come down after being disturbed, so for me I would overboard, skim and paint Wayne.

Hope these help you out mate.

"Best thing to do if you don't want to pay out for a plasterer is rake crack out put mastic in the joint then fill over it.
If you just use filler chances are the crack will return"
