About British Gas and Fuse Energy
Who is British Gas?
British Gas is a trading name of Centrica, a publicly listed company on the London Stock Exchange. Centrica formed in 1997 after the demerger of the former state-owned gas supplier. Today, British Gas is one of the UK's largest domestic energy suppliers and one of the most recognised brands in the market. Its PeakSave scheme gives users half-price electricity on Sundays, and it lets customers switch to another of its fixed tariffs at any time without an exit fee.
Who are Fuse Energy?
Fuse Energy is a privately owned energy supplier that launched in the UK in 2023. Founded by former executives from the financial technology company Revolut, it is backed by venture capital funding. As a smaller challenger in the market, it aims to run an efficient energy business by owning its own generation sites and building its own trading software. It uses artificial intelligence to predict customer demand based on weather and usage patterns, and focuses on a digital-first experience where customers manage accounts mainly through a smartphone app.

Green Energy Comparison
British Gas
According to Citizens Advice data from January to March 2026, the British Gas electricity fuel mix is largely nuclear, with some fossil fuel and renewables. Its standard domestic supply relies on this mixed grid energy. Its parent company, Centrica, has set a target to reach net zero by 2045.
Fuse Energy
Fuse Energy takes a different approach to green energy compared to many suppliers. It does not buy Renewable Energy Guarantees of Origin (REGO) certificates to match its customers' usage, arguing that this practice does not help build new green infrastructure. Instead, it sells the certificates from its own wind and solar farms to fund further renewable projects. As a result, its regulated fuel mix is mostly standard grid energy, alongside the direct clean power it generates itself. It also promises to reinvest its profits into building more renewable energy projects.[1]

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.
