So just been to see sister in law who has had her en suite redone, electrics done by bathroom peoples "electrician". So no rcd protection, cpcs unconnected at fan isolator, flex for cabinet lights on unenclosed block connector in wall cavity, underfloor heating and a new socket for the bedroom both on a radial from the existing ring final with no circuit protection but this bit does have existing additional rcd protection. I wanted to pull a downlight out but didn't want to damage the ceiling, dread to think how they are connected. Apparently they have finished and will be sending her a Certificate for Part P compliance, not on my watch he won't be. He is going to rue the day he opened his tool box in that house.
