About E.ON vs EDF

E.ON and EDF are both part of the group of energy suppliers known as the ‘Big Six’ – older companies that dominate the energy market in the UK.

E.ON

E.ON is one of the largest suppliers of energy in the UK supplying around five million homes and businesses. It is the second largest provider of electricity in the UK. The company was formerly known as Powergen until it was purchased by German company E.ON AG in 2007.

EDF

EDF is responsible for generating roughly a fifth of the UK’s electricity, making it the UK’s biggest supplier of electricity by volume. The company is a subsidiary of the EDF Group, which is wholly owned by the French government.
