About Ecotricity and EDF Energy

Who are Ecotricity?

Set up in 1995 by Dale Vince, Ecotricity is one of the UK's oldest green energy companies and operates as a smaller, specialist supplier. The Green Britain Group owns the company, which runs on a not-for-dividend model. This means it uses its profits to build new renewable energy generation across the country rather than paying shareholders.

Ecotricity

Ecotricity supplies a 100% renewable electricity mix. Rather than just buying certificates to match customer use, the supplier builds its own wind and solar parks to add new renewable power to the grid. For gas, it supplies a mix of green gas made from anaerobic digestion and fossil gas. It offsets the carbon emissions from the fossil gas by investing in direct carbon removal projects in Britain through its Carbon Bank.[1]

EDF Energy

EDF Energy supplies an electricity mix that is largely nuclear, with some fossil fuels and renewables. Because nuclear power does not produce carbon dioxide at the point of generation, the company focuses heavily on zero-carbon electricity. It invests in low-carbon infrastructure to help the UK reach its net zero targets and offers solar panels and battery storage solutions for homes.[2]

Too close to call

Ecotricity offers a cheaper fixed tariff and faster customer service, while EDF Energy leads on variable pricing, app quality, and Trustpilot reviews.

Ecotricity and EDF Energy demonstrate distinct strengths across different categories. Households seeking the cheapest fixed deal will find Ecotricity currently offers the lower price. It also performs better on official service metrics, answering calls faster on average and achieving a higher overall score from Citizens Advice.

Conversely, EDF Energy provides the cheaper standard variable tariff. It also receives stronger customer feedback, holding a higher Trustpilot rating and better scores for its smartphone apps. Because the data points in different directions depending on individual requirements, neither supplier emerges as a definitive overall winner.

Ultimately, the right choice depends on household priorities. Ecotricity may suit those who want to lock in a cheaper fixed rate and value faster call answering times. Alternatively, EDF Energy may be a better fit for customers who prefer a variable tariff and prioritise strong customer reviews alongside a highly rated app.

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.
