Is this something that can just be skimmed, or do you need to apply the
usual two coats of plaster?

Skimmed. Some is pre-finished and may require plaster at the joints.

I have seen the effects on an outside wall in a bathroom. It was tiled over,
so no plastering skills needed. As the tiles were no longer a cold surface
there was never running condensation either. The bathroom was deathly cold,
as many are, any longer.

It will make a significant difference to any room. Fuel is not getting any
cheaper, and it looks like only going one way.
