I've just removed the old tiles in my bathroom and made good with Wickes
Universal Plaster. Can I just tile over this as soon as it looks dry (one or
two days perhaps) or do I have to wait weeks?

The tile adhesive I last used required walls/plaster to be completely
dried out before use. There are probably some that don't, because I
doubt most builders would wait that long. If you just reskimmed, a few
days after it looks dry (gone back to light colour if pink plaster)
would probably be good enough, but if it was a new brick wall and fully
plastered, it takes much longer to dry out.
