Founded in 2022 by ex-Revolut executives Alan Chang and Charles Orr, Fuse Energy supplies energy to more than 300,000 UK households and is building a 1 GW generation pipeline. The company says it runs the full energy value chain in-house—generation, trading and retail—which it credits with delivering roughly 17% efficiency gains versus legacy providers. Fuse uses proprietary trading algorithms and a digital twin of each customer property to predict demand and optimise supply at the household level. Management reports the business has been EBITDA-positive every month since December 2025 and that ARR grew 32% in Q1 to over €472 billion ($550 million). Fuse is opening a 32,000 sq ft headquarters in Canary Wharf, plans to hire over 380 people in the next 12 months, and intends to expand into Europe and North America while launching a plug-in solar product for homes.
