Cheers. You wouldn't believe some of the problems I've had with the builder they used removing parts of the circuit and plasterboarding over switches! I'm always that last to know about problems and I spent half my time fixing bits and pieces for them instead of installing the testing the extension. There is always something else. Oh yeah, what about them removing sockets and leaving earth off...and neutrals...and a live! I had to quickly fix one ring main before my assessment. Not a good start. It's been a proper pain in the arse. Ferking family...
