I think I know the answer - anyone remove remaining doubt?

Hi

It does indeed look like condensation or the results of poor ventilation I would guess.

We do have quite a few projects on damp ion the website that may help with a confirmed cause: https://www.diydoctor.org.uk/diy-how-to-type/damp.htm

Hope this helps

Thanks for that. In the meantime, I'm going to borrow a friend's moisture meter.

You don't need a moisture metre to tell you that's damp/condensation.
