classic situation I reckon :-

Black mould growth at eaves on upstairs ceilings & mildew on
items in built in wardrobes on gable end.

Old solid walled cottage in a row but on a slope so roofs "step
down" a couple of feet every few houses. This is one of the
houses with the step down so there's an extra couple of feet of
"outside wall" at the top of one gable, which is where the built
in wardrobes are.... possibly built to "hide/deal" with the
condensation & mould issues...

Upstairs rooms have (presumably) had ceilings raised in past as
there's now an 18? sloped section of ceiling at the extremities
down to meet the front & rear walls. Behind this I expect there's
sfa insulation hence the condensation & mould.

Loft is lagged *where it is flat & accessible*. There's even a
warning notice about ceilings being weak, crawl boards to be used
etc.

No roofing felt. Surveyor's report recommends roof needs relaying
but no leaks /issues apart from some vintage sag.

So, how to sort?

Rip out wardrobes, insulate gable wall? What about sloped ceiling
sections?

Burn more gas?

Other?

1. The first move is to get a dehumidifier with a humidistat in there & clean off all black mould you can.
2. Then look for all the possible leakage areas

Also tell us about the construction of the beast & the exterior finish. Without that info we're not going to get much further.
