A decade of accelerated funding
The UK's energy software sector has seen substantial growth, securing close to £1 billion in funding across 483 rounds since 2016. The pace of funding has picked up significantly since 2022, with 2025 alone accounting for a record £260 million raised by these companies. This acceleration underscores a growing recognition of software's crucial role in transforming the energy landscape. Notably, breakout scale-ups like energy supplier Fuse, which raised £137 million, and heat pump installer Noda, with £100 million raised, demonstrate the increasing scale of investment in individual companies within the sector between 2023 and 2025.
Key drivers of growth
The surge in investment is driven by a severe power supply-and-demand mismatch across the UK. UK electricity prices remain over 50% above pre-energy crisis levels, higher than nearly every EU nation except Germany. Concurrently, the increasing energy demand from data centres, particularly those powering Artificial Intelligence (AI) applications, is projected to nearly double global data centre electricity use by 2030. These factors combine to create an urgent need for innovative solutions that energy software is uniquely positioned to provide.
Optimising existing infrastructure
With grid connection queues exceeding 700 GW and facing 10 to 15-year wait times, asset-light software is emerging as the fastest route to optimise existing infrastructure. This includes solutions for battery storage, building energy management, and other critical areas that can enhance efficiency and reduce costs without requiring extensive physical overhauls. Software provides the agility needed to navigate complex energy markets and make existing assets work harder.
The central role of Artificial Intelligence
AI applications are taking centre stage in the energy software sector, making up 46% of all energy software deals in 2025 and 66% of first-time funding rounds. This highlights AI's transformative potential in areas such as grid optimisation, demand forecasting, and renewable integration. Adam Chirkowski, a partner at AlbionVC, stated, "The cost of the electron will define the next decade for businesses, investors and nations alike." He further noted, "Energy is one of the largest markets in the world and among the last to be properly digitised."
Addressing infrastructure challenges
The current energy landscape presents significant infrastructure problems, from grid constraints to the need for more efficient energy management. Software offers scalable and flexible solutions to these challenges, making it an attractive area for investment. As Chirkowski highlighted, "For founders with a blend of deep energy and software expertise that are solving infrastructure problems, and investors with the conviction to back them early, that gap is a huge opportunity."
The digitisation imperative
The digitisation of the energy market is not merely an option but an imperative for achieving energy security and sustainability. Investing in energy software aligns with long-term goals for decarbonisation and grid modernisation. Regulatory frameworks in the UK are evolving to support the integration of renewable energy sources and smart grid technologies, creating a fertile ground for innovation and growth in this sector.
Rebuilding the energy system with AI
Fuse Energy is actively contributing to the UK energy software landscape through its unique, vertically integrated "power play" strategy. By owning the entire energy stack and deploying advanced software, Fuse aims to rebuild the energy system from scratch. This approach directly addresses core infrastructure problems, and Fuse aims to leverage AI to optimise costs across the stack and work towards enhancing grid optimisation, demand forecasting, and renewable integration.
Creating a future with power to play with
Fuse's vision is to create a future with "power to play with," where energy is so abundant it ceases to be a constant concern. This commitment to solving fundamental energy challenges through software innovation offers a compelling alternative to traditional, scarcity-driven energy models. By focusing on delivering terawatt-hours of the cheapest, cleanest energy possible, Fuse aims to drive down energy costs and make abundant power accessible to all.
Sustaining growth and impact
The UK energy software sector is poised for sustained growth, driven by ongoing market needs and technological advancements. The increasing involvement of tier-one global venture firms, alongside specialist investors, signals a maturing market with significant potential for impact. Continued investment in asset-light software and AI applications will be crucial for optimising existing infrastructure and integrating new energy sources efficiently.
Long-term vision for a digitised grid
The long-term outlook for UK energy software investment points towards a fully digitised and optimised energy grid. This transformation will not only enhance energy security and reduce costs but also accelerate the transition to a sustainable energy future. The focus on innovation and strategic investment in software and AI will be key to unlocking the full potential of the UK's energy sector.
