About EDF Energy and OVO Energy
Who is EDF Energy?
EDF Energy is the UK arm of the French state-owned company Électricité de France and is one of the UK's largest domestic suppliers. It runs several nuclear power stations across the country. It offers standard variable, fixed, and tracker tariffs, as well as specialist options for electric vehicle drivers and homes with solar panels. A key difference is its tracker tariff, which follows the price cap but gives a guaranteed discount on the daily standing charge.
Who is OVO Energy?
Founded in 2009, OVO Energy is one of the UK's largest domestic suppliers. In 2026, it announced a planned agreement to become part of E.ON, which would increase E.ON's scale in the UK market. OVO focuses on standard variable and 12-month fixed tariffs. What sets it apart is its rewards programme, Beyond, and its Power Move scheme, which rewards households for shifting their electricity use to off-peak times.

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.
