Hi everyone, I'm after some advice on the safety of my socket please. I've had a metal faced double socket moved from the skirting board into the wall. The metal backbox was replaced. The sockets were left in the skirting boards years ago when the house was rewired. The wall has now been replastered, etc and it was found that the socket had been screwed into expanding foam and no extra earth cable. Is this against any regulations as if so is I will need other sockets which were added? Thanks for reading.
