Went to look at replacing sockets for a potential client but they have been installed into the skirting boards (8 x double gangs) took one out & there is no back box. They have all been fitted & screwed straight to the skirting! what are the Regs on this? Dri line box may be a solution but iam trying to avoid chasing the wall out behind them as i cannot remove the skirting. Can i leave them as it is? or am i obligated to fix them correctly? No copper is showing & they all have earth continiuty.
