A key feature of its product range is the Next Pledge tariff, which promises to stay below the Ofgem price cap.
Who are Fuse Energy?

It generates its own power and sells it to customers, owning and running its own renewable energy sites such as solar and wind farms. The company focuses on an app-based approach where customers manage their accounts entirely through a smartphone app with no paper bills. It also uses direct debits that change each month based on actual energy use rather than charging a fixed monthly amount.

Green Energy Comparison
E.ON Next
Based on Citizens Advice data from early 2026, E.ON Next supplies a mostly renewable mix, with some fossil fuels and a tiny amount of nuclear and other sources. The supplier backs its standard electricity supply with renewable energy certificates and agreements with independent UK generators. It does not use carbon offsetting for its standard tariffs. Instead, it makes a one-off donation to the Woodland Trust for every fixed tariff a customer chooses to help restore ancient UK woodlands. It also offers a dedicated green tariff called Next Gust, which is backed by wind energy generated in the UK.
Fuse Energy
Fuse Energy supplies 100% renewable electricity. Rather than buying renewable energy certificates to label its tariffs as green, the company states it puts all its profits back into building and running new renewable energy sites, such as wind and solar farms. It aims to create real-world impact by putting new clean energy onto the grid and making renewable energy cheaper by owning the generation assets. The supplier does not use carbon offsetting, focusing instead on direct renewable generation.

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.
