I suppose it might depend on the area, but wasn’t poured concrete walls more in the 70’s 80’s?

Style of house may also determine construction methods. Ie, semi detached vs high rise flats


Hit a wall with a big hammer and see what moves.
It's a 3rd floor flat, ex-local flat in East London

No RCD protection essentially means if you for example stuck a fork in a socket, instead of getting belted you simply die.

Upgrade it to a new RCBO set up, you won't have to touch it again in your life time.

Changing the CU to one with rcd is not advisable with wiring that old.
There may be faults, borrowed neutrals etc that won’t cause a visible problem until rcds are introduced.
Testing has to be done beforehand.

If it can all be done together, then that is preferable.
Time to get the insulation tester out to check for low values of IR and shared neutrals then eh...?

So very different opinions - someone said I drop the ceiling 1.5cm via plaster and run the cables through there?? Another person said to create 2 different circuits, pushing the cables through and re-wire that way, with the kitchen being on it's own circuit.

As an FYI walls are rock solid, so not sure chasing will be possible without some serious leg work.
