About E.ON Next and Good Energy
Who is E.ON Next?
E.ON Next is one of the UK's largest domestic energy suppliers and is part of the German energy group E.ON. The brand was set up in 2020 to take on customers from Npower and E.ON's older domestic business. In May 2026, E.ON announced a planned deal to buy OVO Energy, which would increase its scale in the UK market.
Who is Good Energy?
Good Energy is one of the UK's oldest green energy companies. Good Energy was founded in 1999 and is a smaller, specialist green energy supplier. In April 2025, the company was bought by Esyasoft, a technology firm backed by Abu Dhabi's International Holding Company, for about £99 million. This deal took the company private. Good Energy has also grown by buying several solar and heat pump installation companies, such as JPS Group, Wessex ECOEnergy, and Amelio Solar.

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.
