Regardless of how much renewable tech you’re planning to install, nearly every self-build home needs a mains electricity supply. The UK’s electrical distribution is owned, coordinated and controlled by a series of distribution network operators called DNOs. The national territory is divided into six principal zones, and there are plenty of subdivisions including independent distribution network operators (IDNOs) as well as specialist service companies that focus on business and big electrical users.
Utility companies often get bad press about how complicated their processes are. However, Ofgem (a non-ministerial government department acting as a national regulatory authority) has helped to shape their operating procedures. So all of them, regardless of region, are legally bound to provide new supply services at fair market prices within acceptable timeframes.
There’s still plenty of paperwork involved, but it’s not as complex as you might think it will be; plus, the companies I have spoken to have always been very helpful.
