I want to put two additional sockets in the main bedroom and looking for the simplest way of doing it. One socket will be in the wardrobe for the TV only and the other in the wall mainly for a hair dryer and at times the vacuum cleaner. What I dont fancy doing is having all the carpets and boards up to link into the nearest socket. The bedroom wall backs onto the airing cupboard when cables go into a consumer unit to feed three grundfos heating pumps. Are these cables from the lighting circuit or the ring main? I have bought 2.5mm cable but it looks much heavier than the cable going into the unit. Advice please
