Who are Fuse Energy?

Fuse Energy is a newer, digital-first energy supplier set up by former banking app employees. It is a smaller domestic supplier that aims to keep its prices below the regulatory price cap. The company runs its services entirely through a smartphone app, where customers can track their half-hourly energy use and get support through a chat feature or an artificial intelligence assistant called Plugs. It uses a variable direct debit system that adjusts payments each month based on actual energy use, and customers with multiple properties can manage all their energy supplies from a single Fuse Energy account.

E.ON Next

According to Citizens Advice data, E.ON Next supplies a mostly renewable mix, with some fossil fuels and a small amount of nuclear power. It offers 100% renewable electricity on specific tariffs, such as its Next Gust deal, which is backed by its own renewable assets, agreements with UK wind generators, and renewable energy certificates. The supplier also partners with the Woodland Trust, pledging to donate at least £500,000 over three years to help restore ancient woodlands when customers sign up for fixed tariffs.

Fuse Energy

Fuse Energy says it generates electricity from its own solar and wind farms, while its regulated fuel mix also includes grid electricity. What sets it apart is that it owns and operates its own renewable energy sites in the UK, including solar farms and a wind turbine, aiming to generate the power it sells to homes. The company states that it reinvests its profits into building new renewable energy infrastructure.[1]

Our verdict
★ Winner: Fuse Energy

Fuse Energy offers a cheaper fixed tariff and higher Trustpilot ratings, though E.ON Next provides a cheaper variable option and proven service metrics.

Fuse Energy is a strong option if you prioritise the lowest-priced fixed tariff and higher aggregate review scores. E.ON Next may be better suited to households that value a lower-priced variable tariff and independently reported service measures.

This outcome should be weighed against the fact that Fuse Energy currently lacks independent service metrics from Citizens Advice and Which?, which limits visibility into its broader operational performance. E.ON Next may suit households seeking a lower-priced variable tariff or those who prioritise established suppliers with documented call wait times and formal vulnerability commitments.

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.
