About British Gas and E.ON Next
Who is British Gas?
British Gas is owned by Centrica and is one of the UK's oldest and largest domestic energy suppliers. It offers standard, fixed, and smart tariffs, alongside boiler cover, heating repairs, and smart home products through its Hive brand. A key feature is its PeakSave scheme, which gives customers cheaper electricity at certain times, such as half-price electricity on Sundays. Customers can also switch between British Gas fixed tariffs at any time.
Who are E.ON Next?
E.ON Next is a subsidiary of the German energy group E.ON and is one of the UK's largest energy suppliers. It was set up to replace the E.ON and Npower brands in the UK. In May 2026, E.ON announced a planned deal to buy OVO Energy, which would increase its scale. The supplier offers standard, fixed, tracker, and specialist smart tariffs. It uses dedicated energy specialists for customer service and offers discounts on home energy technology like solar panels, heat pumps, and electric vehicle chargers.

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.
