I live in a high-rise block of flats. The wall, ceiling, and floor are concrete.
I've removed the electrical trunking as I didn't want to melt it when I was stripping the paint.
What would be the feasibility of chasing the walls to put the cables in the wall?
Needless to say, I don't want to destabilise the wall, especially in a high rise.

The first photo is where the wires are coming in from the consumer unit and the second photo is where the chasing needs to be done. I'll also say that there's a wire coming in from the bathroom and it goes from there into the main bedroom.
