OK, got ya and do you loop back to the CU (as in a ring) or just a single supply from the CU as a radial?

Or do you just send the send the common live, the three light lives, and a single earth cable down the channel and then link the neutrals up in a junction box on the joist

Yeah its not a huge installation Ive already chopped in to the wall for new socket positions and light switch positions, so this is not a problem. So to do it properly I assume you run twin and earth (1.5mm) from CU. Do you then send a twin and earth down to the switches with the twins...
