Damp that seems to be coming through the gable wall

[sotal]

A relative needs some help, and I don't know the answers, so hoping for some advice to feedback. They don't have much spare money and there house is getting to be a bit of a state due to damp.

A few years ago they had an issue with damp. Somebody looked into it and it turned out to be a burst water main next door causing issues.

That was fixed, but the damp issues continued to get worse, to be honest it doesn't look like rising damp as the worst damp is higher up. It's an end town house. Probably more than 100 years old.

They've lived there for about 40 years and it was never an issue until more recently but they haven't done enough to keep it good.

I've attached an image of the outside wall. The roof actually seems ok but I'll try and get into the loft this week to check for anything to there.

My concern was the vents. They all have a dark patch under them (is that damp?) and under the top one there seems to be a large patch which looks darker.

I'm guessing that it was a low budget house when it was built, so would probably be made of the cheapest bricks going - could it just be that they are porous?

The plaster is ruined, they've been running a dehumidifier 24/7 but that just isn't able to keep up with the amount of damp.

Starting to get worried about the health as they are getting older, so we want to help them out but not quite sure where to start.

Probably really poorly insulated, like a lot of houses of that period.

Strip plaster on outside walls, fit breathable membrane, fit 50mm insulation against membrane, trap it back with 25mm deep battens, fill between battens with 25mm membrane, Foil tape all joints (both layers) fit electrics into 25mm void, fit boards and skim.

What would have made it suddenly get worse after decades of being ok. Would it be double glazing (fitted 25-30 years ago) gas central heating (fitted about 25 years ago) it something else.

I've attached some photos of the damp inside, would what you suggest be enough to cause this much damage?

The other issue that we have is there is a solid wall that runs perpendicular to the gable wall separating the front room from the kitchen. The damp spreads in across that wall too, how would that be remedied?
