Fuse Energy Closes $30M Series B, Plans New London HQ

Jan de Vries · 2026-06-04

Fuse Energy, a British energy company, has closed its Series B funding round. New investors 20VC and Collaborative Fund contributed an additional $30 million, joining existing backers Balderton Capital and LowerCarbon Capital. This brings the total funding to date to $250 million. The company says it has been EBITDA-positive every month since December 2025. It achieved group-level profitability even after absorbing costs from new bets, product development, and expansion. Momentum is strong, with ARR climbing 32% in Q1 alone to over $550 million. ### The Vision Behind Fuse Energy Alan Chang, CEO and co-founder at Fuse Energy, explains their core belief: "We started Fuse Energy with a simple belief: that energy should be low-cost and abundant. Getting there means owning the problem end-to-end. Whether that's writing your own trading algorithms, building your own solar farms, or engineering your own products." Chang adds, "Three years since we launched to the UK public, we're already profitable. We're the cheapest fixed tariff on the market, and we're just getting started. That's what a resilient, efficient, and home-grown energy model actually delivers."  ### How Fuse Energy Stands Out Fuse Energy's additional Series B funding sits within a 2026 EU-Startups dataset. It shows continued capital allocation to energy platforms that combine software, trading, financing, storage optimization, and renewable generation. The closest UK comparables include: - Tem's $73.4 million Series B for energy transaction infrastructure - Exergy3's $13.3 million Seed round for thermal storage - Caudal Energy's $5.7 million raise for tidal power - Rivan's $33.5 million round for synthetic fuel production Across Europe, larger infrastructure-linked commitments like Cloover's $1.21 billion facility sit alongside growth rounds for Entrix, Reel, Hybrid Greentech, and Capalo AI. This points to investor focus on grid flexibility, energy-market optimization, and distributed energy deployment rather than a single clean-energy subcategory. ### Why London is the Perfect Base "London is one of the best places in the world to build a technology company, and we're investing here for the long term," adds Alan. "The UK has the talent, the ambition, and the customer base to lead the next chapter of energy. What's been missing is the pace and the coordination to build at the scale this moment demands." Founded in 2022 by ex-Revolut executives Alan Chang and Charles Orr, Fuse Energy aims to reshape the energy sector. They make energy lower cost and more abundant. They supply energy to more than 300,000 UK households and are building a 1 GW generation pipeline. ### The Secret Sauce: Owning the Whole Chain Where traditional suppliers typically outsource generation, trading, and retail, Fuse Energy takes a different approach. By building the entire energy value chain in-house, the company has reported efficiency gains of around 17% more than legacy providers. They remain resilient during periods of market volatility. That efficiency is what the company says allows them to keep customer prices low, even when wholesale energy costs spike. The difference is in how each part of the chain is run. For example, when buying energy on wholesale trading markets, most suppliers rely heavily on historic demand to predict energy consumption. Instead, Fuse Energy uses its own algorithm built on a digital twin of every customer property. It factors in real-time inputs like local weather and building energy efficiency data to predict and balance supply and demand at the individual household level. The result is reportedly less waste across the system. These efficiency gains can be passed directly to consumers through lower energy bills. ### New HQ and Hiring Spree To support the rapid expansion of its engineering, operations, and commercial teams, Fuse Energy is opening a new 32,000 square foot headquarters in Canary Wharf. The company plans to hire more than 380 people over the next 12 months. This represents an investment of approximately $27 million. This move signals Fuse Energy's commitment to London and the UK's energy tech ecosystem. With strong financial backing, a profitable business model, and innovative technology, Fuse Energy is positioned to challenge traditional energy suppliers and deliver on its promise of low-cost, abundant energy.
