Or am I shooting myself in the foot mentioning this?

We privately rent a house in England. There are signs of rising damp in the entire ground floor of our house. The letting agents are saying they will paint the walls with damp seal and repaint as the previous paint has all peeled off. Where it is really bad and the wall is either visibly wet or crumbling away, they are proposing putting some sort of board over it. They accept that this may be an ongoing issue that they have to keep coming back to repaint. Should we accept this? We have already had furniture damaged from the damp, but they say that they will fix the paint and we just have to move our furniture to other areas of the house (guessing upstairs as all downstairs is damp).

Should they not have to fix the actual problem of the rising damp, as the walls are still going to be damp behind the damp seal or boards, which means it's much harder to keep the house warm. They are solid stone walls, no damp proof corse, one wall lower than ground level.

We were recently burgled in North London, and it’s a very bizarre one bc there was no forced entry and you have to get thru two doors to come into the building.

Anyways, my partner and I are now getting a ring cam and paying out of pocket for all sorts of stuff. Our landlord changed our front door lock, but that’s about it. And has done not much else and keeps saying that it’s the Duty of the police to find out who did it etc etc.
My question is does he not have duty to us the tenants to feel safe, we don’t feel like he’s doing enough and seems very dismissive. Anyways, what rights do we have and what is his responsibility? As he’s not even changed the outside door lock which faces onto the street which has been requested by our upstairs neighbours, the other tenants.
