London’s Fuse Energy Secures €25 Million In Series B Round

The latest investment brings the company’s total funding to around €214 million ($250 million).

Founded in 2022 by former Revolut executives Alan Chang and Charles Orr, Fuse Energy supplies power to more than 300,000 UK households and is developing a 1 GW generation pipeline as it looks to scale its energy infrastructure.

The company reports that it has been EBITDA-positive every month since December 2025 achieving group-level profitability even while investing heavily in product development, expansion, and new initiatives. Growth has also accelerated with ARR rising 32% in Q1 alone to more than €472 million ($550 million).

Fuse Energy is positioning itself as a vertically integrated alternative to traditional utilities. While most energy suppliers outsource generation, trading and retail functions, Fuse brings the entire value chain in-house.

The company says this approach delivers roughly 17% greater efficiency than legacy providers and improves resilience during periods of market volatility.

That efficiency, according to the company, enables it to keep customer prices lower even when wholesale energy costs fluctuate sharply. A key difference lies in its forecasting approach: instead of relying primarily on historical consumption data, Fuse uses proprietary algorithms and a “digital twin” of each household.

These models incorporate real-time inputs such as weather conditions and building efficiency to forecast demand and balance supply at the individual home level.

The company claims this reduces system-wide waste and translates into lower energy bills for customers through more precise matching of supply and demand.

To support its rapid expansion, Fuse Energy is opening a new 32,000 sq ft headquarters in Canary Wharf and plans to hire more than 380 employees over the next year, representing an investment of about €23 million ($27 million) in UK talent. The company currently employs over 400 people.

Looking ahead, Fuse plans to expand across Europe and North America and launch a plug-in home solar product designed to help households generate low-cost renewable energy directly at home.

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.”
