What They Do
Fuse Energy is a London-based energy company that began in 2022 focused on supplying cheaper electricity and building renewable generation assets. It operates two related businesses: a retail electricity supplier targeting homes with low-cost tariffs and a digital-first, app-based customer experience, and a B2B energy services arm that supports businesses, nonprofits, and municipalities with energy procurement, fixed-rate supply, and community solar solutions (source: fuseenergy.com) (source: fuseenergygroup.com). The company’s technology focus centers on solar farm development, data science for demand forecasting, and grid-market participation rather than a single hardware platform, enabling it to optimize power purchasing and supply balancing (source: welcometothejungle.com). Fuse Energy’s vertically integrated model combines solar generation with software-led customer operations to deliver cheaper, greener energy to price-sensitive residential and commercial customers (source: welcometothejungle.com).
Projects & Track Record
Fuse Energy’s project portfolio is focused on solar farm development and power-market operations rather than large, named utility-scale assets with published capacity ratings. The company has built solar farms to provide cheap renewable energy and offers community solar and energy procurement services to its customers (source: welcometothejungle.com) (source: fuseenergygroup.com). It currently supplies electricity to approximately 50,000 homes and is actively planning expansion into Ireland, Europe, and the United States (source: welcometothejungle.com). On the commercial side, Fuse Energy Group works with businesses, nonprofits, and municipalities, and is developing retail energy channel partnerships to broaden its market reach (source: fuseenergygroup.com).
Recent Developments
Fuse Energy has experienced rapid growth and significant funding milestones in recent years. The company completed a $10 million early-stage venture capital round in July 2025, followed by a $100 million late-stage round in November 2025, fueling its expansion plans (source: welcometothejungle.com). It reported €76 million in annualised revenue with 7x year-on-year growth, reflecting strong market traction and operational scaling (source: welcometothejungle.com). The company is actively expanding its footprint beyond the UK into Ireland, broader Europe, and the US markets (source: welcometothejungle.com).
Working There
Fuse Energy hires across a diverse range of roles including engineering, operations, solar development, commercial functions, and software development. Current and past job openings include Senior Backend Engineer, Mechanical Engineer, Firmware Engineer, Engineering Manager for Solar EPC, Senior Front-End Engineer, Brand Designer, Growth roles, AI Operations Manager, and Site Manager for Solar EPC (source: workable.com) (source: welcometothejungle.com). The company also recruits for commercial retail energy channel partner managers, indicating a focus on expanding business partnerships (source: fuseenergygroup.com). Fuse promotes a fast-moving startup culture characterized by "fair wages," "long hours," "high voltage," and offers stock options, reflecting a high-energy environment with growth opportunities (source: f.energy).
