About Fuse Energy and OVO Energy

Who is Fuse Energy?

Alan Chang and Charles Orr set up Fuse Energy in 2022. It is a privately owned business backed by venture capital investors. The company bought Paddington Power to get its supply licence. It is a vertically integrated supplier, meaning it owns and runs solar and wind farms in the UK and uses its funding to build new renewable capacity. Through its own growth, it has become a fast-growing energy startup and is now one of the UK's newer domestic suppliers.

★ Winner: Fuse Energy

Fuse Energy wins on price and app ratings, but OVO Energy offers established independent service metrics.

Based on the available data, Fuse Energy edges ahead of OVO Energy for most households. It offers a cheaper fixed tariff and performs better across customer sentiment metrics, including Trustpilot and app ratings. However, because Fuse Energy lacks independent scores from Citizens Advice and Which?, this assessment is made with medium confidence.

Fuse Energy may suit households looking to lock in a lower price and manage their account through a highly rated app. Alternatively, OVO Energy may be a better fit for those who prefer a supplier with a longer track record and established Citizens Advice metrics.

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.
