EDF Energy is one of the UK’s largest energy companies and a wholly-owned subsidiary of the EDF Group, one of Europe's largest energy groups. We generate around 6% of the UK's electricity, employ nearly 12,000 people, and deliver electricity to 7.9 million customer homes and businesses through our public networks.

The company is organised into three branches:

• Customers Branch sells energy to our residential, SME and business customers.
• Energy Branch manages our electricity generating portfolio, and purchases electricity and gas in the energy wholesale market.
• Networks Branch runs a centre of excellence for the development, construction and operation of public and private power networks.

When three energy companies - SEEBoard, London Energy and SWEB - were brought together, EDF Energy was born.Since then, they grown steadily, integrating and streamlining their operations to become more responsive and effective in a fast-changing marketplace.

They are now involved in some of the UK’s most important projects and developments, growing to become one of the country’s largest energy companies.
