morning all, ive attached a really basic drawing of what i'm trying to explain. we had a extension done about 10 years ago, last night i realised that some of the floor sockets have no power, i checked the main fuse board and no fuses have tripped. There are still some sockets which are working which are literally a few feet from the ones which are not, the induction hob is working in the island, the cupboards have a fridge and also microwave and ovens and all are working.
