About EDF Energy and OVO Energy
Who is EDF Energy?
EDF Energy was formed in 2002 and is the UK retail branch of the French state-owned EDF Group. It is a long-established and widely recognised energy brand, as well as one of the UK's largest domestic energy suppliers. The company is heavily involved in UK nuclear power generation and is leading large-scale building projects such as the Hinkley Point C nuclear plant. What sets it apart is its focus on zero-carbon nuclear power and its range of specialist tariffs for households with low-carbon technology.
Who are OVO Energy?
OVO Energy was set up in 2009 and is owned by OVO Group. It grew significantly after buying SSE's retail business in 2020, making it one of the UK's largest domestic energy suppliers. In 2026, E.ON announced a planned buyout of OVO's retail business, which would increase its scale in the UK market. What sets OVO Energy apart is its focus on smart technology and rewarding customers for changing how they use energy through its Beyond loyalty programme and Power Move scheme.

Green Energy Comparison
EDF Energy
Based on Citizens Advice data, EDF Energy's electricity fuel mix is largely nuclear, with some fossil fuels and renewables. The supplier is a major generator of zero-carbon electricity and backs its standard home tariffs with 100% zero-carbon nuclear electricity as standard. This means it buys enough zero-carbon nuclear electricity to match what its customers use over the year. It also refers customers to the Snugg Carbon Cashback programme, which pays eligible solar and heat pump users for the carbon savings they make.[1]
OVO Energy
Based on Citizens Advice data, OVO Energy's electricity fuel mix is largely fossil fuels, with some renewables and nuclear energy. The supplier does not generate its own electricity. To help customers cut their carbon footprint, it offers a 1 Year Fixed + Greener Electricity tariff that adds greener electricity to their plan. It also runs the Power Move scheme, which rewards customers for using electricity at greener times of the day. As well as this, OVO has planted 5 million trees in schools and communities on behalf of its customers.[2]

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.
