Evening all, just after clarification really on a couple of things. 1. Just fitted 8 GU 10 in a kitchen & the lamps are the energy efficient ones ie 35w equivalent to 50w. Would this count in regard to Part L of the building regs. Talking about an existing house not new build. 2. On a TT install is the double pole isolating switch on the consumer unit still counted as complying with double pole isolation. There was another query but I have forgotten what it was, must be my age.
