What is causing the mould. That is the question.
The problem is that the spores will just seed somewhere else usually and so
the main thing is to find the damp source and stop it first.

The main contributor seems to be condensation.
Recently moved into an electric only flat and are waiting to see our
first bill that includes heating, before investing in electrical
solutions like dehumidifiers or powered extractors.

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

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

The best time to do this is before you buy the place :-)

That is so true. I never did perfect my property buying skills and
it's unlikely that there'll be many more practice opportunities.

That's why I find uk.diy such a help. There's a lot of knowlege
generously offered here, that often compensates for my lack of
expertise.


At the end of the day it boils down to lack of insulation and/or
not enough heat and/or ventilation.

All of those for sure, though I'm hoping to overcome some of them and
there are some positive aspect to the place. Quiet, by the sea, no
passing traffic but very close to a mainr bus route. Short walking
distance to the town and several big supermarkets.

This isn't a sales pitch, by the way :-)
Even I wouldn't mistakenly introduce black mould as a feature of one
of those.

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.
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.
