About Ecotricity and EDF Energy
Who are Ecotricity?
Ecotricity was set up in 1995 by Dale Vince and is a not-for-dividend company based in Stroud. It is one of the UK's oldest green energy suppliers and operates as a smaller, independent supplier. Instead of paying shareholders, it uses customer bills to build new wind and solar parks in Britain through its Bills into Mills model. It also offers vegan-certified energy.
Who are EDF Energy?
EDF Energy is owned by the French state-owned energy company Électricité de France. It is one of the UK's largest domestic energy suppliers and a major generator of electricity, running several nuclear power stations across the country. A key difference is its scale as a major generator of zero-carbon electricity.

Tariffs and pricing
Ecotricity’s lowest-priced option is a fixed deal, EcoFixed - 2 Year August 26 v1, which costs £1,677 a year. This requires a 24-month contract and includes a total £200 exit fee. In contrast, EDF Energy’s cheapest overall tariff is a tracker, Simply Tracker Sep27, priced at £1,755 a year. It has no fixed term but carries a £50 exit fee.
The trade-off is clear: EDF Energy’s tracker is cheaper for households wanting variable pricing, while Ecotricity’s 24-month EcoFixed deal costs less for those who want fixed rates.

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.
