About E.ON Next and OVO Energy
Who is E.ON Next?
E.ON Next is the UK retail brand of the German energy group E.ON. It was set up in 2020 to replace the E.ON and npower brands and is now one of the UK's largest suppliers. In May 2026, E.ON announced a planned deal to buy OVO Energy, which would increase its scale in the UK market once approved. The supplier offers standard and fixed deals, alongside specialist options for electric vehicle owners and homes with heat pumps. What sets it apart is its Next Pledge tariff, which tracks just below the price cap, and its use of dedicated staff to handle customer support.
Who are OVO Energy?
Founded in 2009, OVO Energy grew in 2020 when it bought the retail business of SSE, making it one of the UK's largest suppliers. E.ON announced a planned deal to buy OVO Energy in May 2026, though the brands continue to run independently while waiting for approval. OVO offers standard and fixed-term tariffs, with options to add boiler cover or a greener electricity upgrade. A key feature is its Charge Anytime add-on for electric vehicle owners, as well as its Beyond rewards programme which gives customers perks and discounts.

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.
