I've seen some truly terrible cover-ups on damp in my time..
Particularly when I was looking to rent in Brighton for a short while in my life- it seemed like every place I went was damp, and they just tried to paint over it!

I'm pretty sure that anyone familiar with living in damp conditions can just smell/taste it in the air..  Lips Sealed

The first, and easiest, things to look for are,

guttering, is it in good condition and not blocked in any way? Go out when it's raining hard and see if any water is coming out where it shouldn't.

Pointing, is the pointing in good condition.

Look for any reason why the ground at the base of the walls may be particularly wet.

Yes that's what I meant. Thank you for your reply. Apparently the house  has had a damp proof course before we moved in about 5 years ago. More matches seem to be appearing too. It looks awful!

By dot and dab patches do you mean dark marks on the wall following the positions of the dot and dabs? If so they are usually caused by damp on the outside wall spreading through the dot and dabs into the plasterboard. You would need to fix this before you could paint to be sure the marks didn't reappear.
