I would certainly not want to use them to hang kitchen cupboards from.
They pull out of the plaster too easily.

If the plasterer made sure there is plasterboard adhesive where the
fixings will go, then it's easy - just use 4" long screws and normal
plugs.

If you find areas without adhesive, my choice would be to cut back the
plasterboard around the area, and fill it with one-coat. Once that's gone
off, drill and fix.

Hmmm - so what sort of plugs do I use with a 4" screw?

Many thanks for your help.
