How can I stop damp coming through wall?

I'd be surprised if there wasn't one. The brickwork and iron waste pipes suggest it is not too old. Have a look under and beside the doorstep.
Typically it would be immediately below, or above, the original airbricks. It may have been pointed over. Have a look at similar neighbouring houses for clues.
I still suspect the source of water is drains leakage, if your water meter shows no sign of a pipe leak.
The ground hear thar airbrick looks wet, and there is some kind of drain beside it. Can you lift some pavers and look for wet ground?

Look at hygroscopic salts contamination. Look towards a blocking render internally using sand /cement render with SBR slurry and waterproofing add-mixture in the render.

Cor, that's quite the undertaking - it'd probably be easier to remove the chimney; in this day and age of sky high prices, who wants a gaping hole to the world letting their paid-for heat out?
You may not have a damp course as the bond on parts suggest solid wall which were probably built using lime mortar.
Not suggesting you go down the route I did but interesting reading :

DPC became mandatory in London in 1875. Some more backward areas were later, but the building shown looks to me like no earlier than 1930, and is not rural. Lime mortar was still being used in the 1940s, typically with slate DPC and sometimes with bitumen products.
I would be surprised if it had been built without a DPC.

Visible damp in a bathroom is most often leaks (if near the floor) or condensation (if up the external wall).
A damp concrete floor is often leak-related.
Excessive accumulation water can also be a result of a buildup due to an inability to evaporate like the building may have designed to do due to cement products or impervious coatings blocking the way.
Hi, I recently got 2 separate damp companies to look at it.
Both said it was probably due to poor ventilation.
One said that it's likely that water is running down between the wall and concrete.
He suggested I should build up a large triangular section of mortar at the bottom of the wall to help water run away.
He also said it could be done with a French drain but that was a lot more work.
Does the mortar idea sound a good idea?
