this is why i asked, went to a guys house the other day cos he built his own kitchen extension years ago but now wants to sell the house, anyway he never got it signed off by BC and now the inspector has come round he wants to see Part P documentation for the wiring, well i pulled one of the downlights down ( theres 20 overall!!) and he has just looped in and out with the live and neutrals and cut the cpc's off!!, am i correct in thinking that the reason there has to be continuity of the cpc is for obvious reasons in the event of a fault, hence not just using twin live and neutral cable?
The BC wants them to all be fire rated too so its a case of replacing them all so i shall be stripping back all the cables and using wagos and line enclosures anyway.
