Which, if the photos are on the other side of that wall, is where the damp patch is ... no?

There and then its extended to left side as well.

yeah boiler pressure is ok as long as one tap is on.
if i switch on both downstairs and upstairs shower then pressure goes down - which i guess is common with combi boiler.

i have fixed it once (sanding, putting easy filler, sanding again, painting) but it happened again in a month time.

Sorry I meant radiator boiler pressure . There is an indicator on the boiler how many bars (how pressurised) the radiators are . If this is going down slowly then there is a leak .

Oh I see. Sorry.
Yeah boiler pressure has gone down 2 times so far in 8 months since install.
I have increased it using valve both times.

it's bricks wall, multi finish plaster, crown paint on living room side. other side is tiles.

initially i thought its because of builder painting on wet plaster. so i repaired it in summer month. but it happened once again in a month time.

Where do the pipes run? If solid brickwork has it been chased? Or is the plaster so thick they are buried within? What is the pipe work material (copper, plastic or what?). Assume that there are no pipe joints in that area as should be continuous run.

The issue is very isolated so at a guess I would think that there is a very slight pipework leak.

Then something is leaking somewhere (probably in the same region as the damp wall) . Maybe some radiator sealant would do the trick - I'm sure someone else here will come along to give better advice .

its plastic pipes and run in the floor.
its thick plaster and this is happening mostly on surface.

So a company called polygon checked for leak and didn't find any leaks.
However they said its damp (there was a leak in my property from mains pipe couple of months ago in utility room which is next to bathroom and I found out about it only after few weeks (only when water started to flow below washing machine which hides connection) so I then fixed it myself but by that time too much water had gone under floor (floor is most part timber joists but bathroom and utility room which joins living room are concrete floor)).
He checked with moisture meter and ratings are 999 (highest) near this wall, in bathroom and in utility room.

He asked me contact my insurance which I did.
Now insurer gave me two options:
1. I take 915 pounds which they have estimated based on pics minus 350 pounds of excess (effectively 565).
2. They send their contractor to fix it.

I am confused as to what to do.
1. It's not growing any more so I could fix it myself very cheaply (however damage can appear again as it did once in past unless floor is dried properly. But this way I don't need to put claim.
2. I put claim, take 565, do it myself but again damage can appear again.
3. I asked them to fix for me. This gives me guarantee that it won't happen again and if it does they will fix again without another claim (but in this case I have to pay 350 from my pocket and one claim is recorded on me)

Any help/suggestions appreciated.

Run a dehumidifier in the utility room for a couple of months, and do the same living room. In March, have a look at the state of the plaster, and if it is bone dry, get it skimmed - I'm assuming the affected wall is brick ?
If it is a simple timber stud wall, it should dry out fairly quickly. But the concrete floor will take a while longer.

Thanks for your reply.
Yeah affected wall is brick.
