About E.ON Next and Good Energy
Who are E.ON Next?
E.ON Next is the retail arm of the European energy group E.ON. It is one of the UK's largest energy suppliers, having grown by taking on customers from npower and other suppliers. In May 2026, E.ON announced a planned deal to buy OVO Energy, which would increase its scale, though the two companies run independently while waiting for regulatory approval. It offers standard and fixed tariffs, as well as specialist options for electric vehicle drivers and homes with heat pumps. A key feature is its Next Pledge tariff, which tracks below the government price cap. It also uses dedicated staff to handle customer service.
Who are Good Energy?
Founded in 1999, Good Energy is an independent British supplier owned by Good Energy Group Limited. It is one of the UK's oldest renewable energy pioneers and operates as a smaller, specialist supplier. The company recently expanded by buying solar and heat pump installation businesses, and in 2026 signed a large energy supply deal with Ørsted to buy power from offshore wind farms. It focuses on 100% renewable electricity and supporting independent UK generators, offering standard, fixed, and specialist tariffs for electric vehicle drivers and solar panel owners.

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.
