About EDF Energy and Outfox Energy
Who is EDF Energy?
EDF Energy is one of the UK's largest domestic energy suppliers and is owned by the French state. It bought British Energy in 2009, giving it a large network of nuclear power stations. The supplier offers standard variable and fixed deals, as well as specialist options for electric vehicle owners and homes with solar panels. Its heavy use of nuclear power allows it to back its standard tariffs with zero-carbon electricity.

The company positions itself as a smaller challenger brand, offering a straightforward mix of standard variable, tracker, and fixed deals. It focuses on keeping its running costs low to offer cheaper fixed deals than many larger suppliers.

Green Energy Comparison
EDF Energy
EDF Energy's electricity fuel mix is largely nuclear, with some fossil fuels and renewables. Because nuclear power does not produce carbon emissions at the point of generation, the supplier frames its electricity as 100% zero-carbon. This zero-carbon electricity is backed by its own nuclear generation. The company is also building the new Hinkley Point C nuclear power station to add to the UK's zero-carbon energy supply.
Outfox Energy
Outfox Energy's electricity fuel mix is a mix of fossil fuels and renewables, with some nuclear. The supplier does not currently offer a 100% renewable or zero-carbon tariff as standard. It backs its renewable energy supply by buying Renewable Energy Guarantee of Origin (REGO) certificates to match customer use.

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
