    Pollyfilla. Let it dry then light sanding. Chalk works too.

    Chalk or caulk?

    Get some plasterboard screws, find the joists and screw them in first, otherwise you are only 'papering over the cracks' and they will re-appear.

    Fill it with Gyproc promix (from your local builders provider, infinitely cheaper than 'DIY' filler) wait a few days, sand then paint.

    Just to add, painters caulk is fine, but it is like a rubbery infill that will shrink over time and you will still see the cracks.

    Another option is plasterer mesh, and 1 or 2 coats of light plaster. Sand and paint, and job done

    Do cracks normally occur under the joists?
    Just trying to understand where the screws go in relation to the crack.
    Do you screw both sides of it ??

    You cant screw both sides. The reference above was made for making good the attachment of the boards to the underside of the 1st floor joists. Builders in older houses used plasterboard nails that loosened over time / stress of walking on 1st floor. Using screws from the ceiling side into the joists will reduce the chance of it reoccurring. Once screws are in place, then just use a scraper for application of some 5 minute filler, a light sanding and repaint.

    Usually its not the slabs that are the problem but the joists above. You can solve this with some noggins in the right place, then fill and paint the cracks.
