Our history
Here’s a brief history of our company over the years. We have been UK Power Networks since 2010.
Historically, electricity networks were operated separately:
- London Electricity (previously the London Electricity Board, LEB) managed the electricity network in London;
- Eastern Electricity (previously the Eastern Electricity Board, EEB) managed the electricity cables and lines in Norfolk, Suffolk, Essex, Hertfordshire, Cambridgeshire, parts of Buckinghamshire and most of Bedfordshire, and
- SEEBOARD (previously the South Eastern Electricity Board, SEEB) looked after the electricity network in parts in Kent and part of Surrey, and Sussex.

Our industry has changed a lot over the years. In 1998 Eastern Electricity became TXU Energy, which together with London Electricity then merged in 1999 to form 24seven Utility Services. 24seven Utility Services handled electricity distribution for the next three years, before it expanded even further when SEEBOARD joined them under the ownership of the LE Group in 2002. The following year 24seven Utility Services rebranded to become EDF Energy Networks.
EDF Energy Networks then managed the electricity distribution network across London, the South East and East of England for the next seven years until 2010 when they were acquired by the CK Group and renamed UK Power Networks.
UK Power Networks celebrated its 15th anniversary in 2025 is very proud to be continuing to deliver a safe and reliable supply of electricity to 8.5 million homes and businesses, and help enable the UK's transition to a low carbon future. Other companies operate electricity networks in other parts of the UK.
