Might be useful to discuss the problem with neighbours in similar flats.

Discussed it with a few, who have had similar problems.

Way back we had a thread on extract heat recovery. This was related to
issues of condensation in a North facing, 60's build, uninsulated cavity
wall block.
The kitchen, which is the worst affected room, is north facing, 70's
build, with uninsulated cavity.

sounds like a good opportunity, CWI could help there. You'll still need to get rid of excess damp though.

Where clothes drying, excessive showering, cooking etc. put lots of
moisture into the air which promptly condensed on the cold upper parts
of the North walls.

That certainly rings a bell.

Luckily the flats were commonhold and nobody objected to us putting in a
central heat recovery system plus extractors for bathroom and cooker
hood.

These flats have a jointly held freehold which sounds quite similar.
Getting consensual agreement is said to be tricky though.
Maybe the AGM is the time and place.

The extraction used on the existing Electrolux cooker hood stops at
the activated carbon filters contained within.

I don't know the model name and number of this cooker hood. Nothing
immediately visible. It may be that its current setup can easily be
modified to connect a vent pipe leading to an as yet non existent hole
in the wall. Maybe A ZipUp tower and a diamond hole cutter will
suffice for that. I've done such things before in my earlier DIY days.
Someone else will have to do it this time.

holes can be cut from indoors only - debris can fall out of course so some cordoning may be needed. A dehumidifier is generally cheaper though.

It puzzles me how many people produce tons of steam when cooking. Learning not to is trivial.
