About Fuse Energy and Scottish Power
Who is Fuse Energy?
Fuse Energy is a newer energy supplier set up in 2022 by former staff from the banking app Revolut. It is a smaller challenger brand that runs a vertically integrated model, meaning it owns renewable generation sites, trades on the wholesale market, and supplies homes directly. It aims to grow by offering an app-based, digital experience rather than using traditional call centres.

Green Energy Comparison
Fuse Energy
Fuse Energy invests in its own renewable energy projects, including solar farms in England and a wind farm in Scotland. It does not buy Renewable Energy Guarantees of Origin certificates to claim a 100% renewable mix, as it calls this practice misleading. Instead, it sells its certificates to fund new projects. This means the electricity it supplies to customers reflects the standard grid mix alongside its own generation. It does not currently offer a specific green tariff in its mainstream range.[1]
Scottish Power
Scottish Power's parent company builds renewable energy sites, and the supplier generates its own renewable electricity through UK wind farms. It offers specific green tariffs backed by 100% green electricity from these sites. However, the overall mix of electricity it supplies to its domestic customers is largely fossil fuels, with some renewable and nuclear energy.

Fuse Energy is the stronger option on the available tariff pricing and Trustpilot data, while Scottish Power has more independent regulatory data.
Based on the available pricing and review data, Fuse Energy leads this comparison. It provides a notably cheaper fixed tariff and secures higher customer satisfaction scores on Trustpilot. The digital experience is also highly rated, which may suit households preferring to manage their energy via an app.

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.
