Green Energy Comparison
British Gas
British Gas aims to help the UK reach net zero by 2050. It focuses on cutting carbon emissions from homes by selling smart technology like heat pumps, solar panels, and electric vehicle chargers. Based on data from Citizens Advice, the British Gas electricity fuel mix is largely nuclear, with some fossil fuel and renewables.
Fuse Energy
Fuse Energy owns and runs solar and wind farms in the UK. It focuses on helping customers use energy in a greener way by shifting their power use to off-peak times, which helps to ease the strain on the national grid. The supplier supports green technology by offering tariffs designed for EV charging and solar power export. It publishes a fuel mix that shows the split of its own solar and wind generation alongside the energy it buys from the grid, rather than buying renewable energy certificates to claim a fully renewable mix.[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.
