A three-bedroom house built today must have at least 38 sockets.
(This is more than twice as many as 30 years ago. The number has been set by the National House Building Council’s technical standards. They recommend 4 each in the kitchen and utility room, 4 in the living room, 8 in a living/family room with 2 near the TV aerial. Funnily enough they reckon there should be 6 in the main bedroom, and four in other bedrooms.
I have no idea why you would need so many sockets in the bedroom. The mind boggles.)
