About OVO Energy and Utilita Energy
Who is OVO Energy?
Stephen Fitzpatrick started OVO Energy in 2009. Based in Bristol, it is one of the UK's largest energy suppliers. The company grew organically and through acquisitions, including its purchase of SSE's retail business in 2020. In May 2026, OVO announced a planned sale of its retail business to E.ON. This deal is waiting for regulatory approval, and OVO continues to run as a separate company until it completes.
Who is Utilita Energy?
Bill Bullen started Utilita Energy in 2003. Based in Hampshire and owned by Luxion Group, it is one of the UK's largest independent energy suppliers. The company was set up to challenge older suppliers by focusing on pay-as-you-go energy and smart meters. It was the first UK supplier to fit a smart meter in a home in 2008.

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.
