Fuse Energy, a British energy company, has closed its Series B, with new investors 20VC and Collaborative Fund contributing an additional €25 million ($30 million) and joining existing backers Balderton Capital and LowerCarbon Capital – taking total funding to date to €214 million ($250 million).
The company says they have been EBITDA-positive every month since December 2025, achieving group-level profitability even after absorbing the costs of new bets, product development and expansion. The momentum has been gaining with ARR climbing 32% in Q1 alone to over €472 billion ($550 million).
Alan Chang, CEO and co-founder at Fuse Energy, says: “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.
“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.”
“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 by making energy lower cost, and more abundant. They supply energy to more than 300,000 UK households, and are building a 1 GW generation pipeline.
Where traditional suppliers typically outsource generation, trading, and retail, Fuse Energy explains they are taking 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 while remaining 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 – factoring in real-time inputs like the 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, capturing efficiency gains that can be passed directly to consumers through lower energy bills.
To support the rapid expansion of its engineering, operations, and commercial teams, Fuse Energy is opening a new 32,000 sq ft headquarters in Canary Wharf. The company plans to hire more than 380 over the next 12 months, representing an investment of approximately €23 million ($27 million) in UK talent. Today, the company employs more than 400 people.
The company plans to expand across Europe and North America, and will launch a plug-in solar solution enabling households to generate low-cost renewable energy directly at home.
