Sunsave is a London-based technology company founded in 2022 that provides a subscription-based service for solar panels and battery storage, enabling UK households to access renewable energy without upfront costs.[1][2][3] It targets residential customers, particularly families with high energy bills, solving the problem of expensive and complex solar adoption by offering installations that generate and store electricity, reducing bills by hundreds of pounds annually while promoting energy independence.[1][2] The company has shown strong growth momentum, securing £113 million in funding to scale operations, expand into EV chargers, heat pumps, and smart energy management software, and serve customers across England and Wales with plans for UK-wide rollout.[2]
Sunsave was co-founded in 2022 by CEO Alick Dru and Ben Graves, who launched the company from London with a mission to make solar and battery storage accessible to all UK households through a simple, affordable £0-upfront subscription model.[2][3][4] The idea emerged amid rising energy costs and a push for greener homes, addressing barriers like high installation expenses that had constrained UK solar adoption.[2] Early traction was rapid, with quick customer uptake leading to seed funding of £5.4 million (bringing total early funding to £9.2 million) from Norrsken VC, IPGL, Plug and Play, and angels like Stuart Rose and Michael Spencer, followed by a major £113 million raise to fuel expansion.[2][3]
Sunsave rides the UK rooftop solar revolution, fueled by energy crises, net-zero goals, and falling solar costs, timing perfectly with government incentives and household demands for independence amid volatile bills.[2] Market forces like rising electricity prices and regulatory support for renewables favor its model, disrupting a sector long limited by upfront barriers and positioning Sunsave as a leader in solar-plus-storage.[1][2] By enabling grid participation and home energy stacks, it influences the ecosystem toward decentralized, smart energy, accelerating the shift to clean tech and potentially reshaping how millions access sustainable power in Britain.[1][2]
Sunsave is poised to dominate UK residential renewables with its funding war chest, product expansions, and subscription innovation, targeting a "full energy stack" that could make it the go-to platform for net-zero homes.[2] Trends like EV adoption, heat pump mandates, and AI-driven grid tech will propel its growth, while national expansion and potential exports amplify influence. As it scales from challenger to category leader, Sunsave could redefine energy access—one rooftop at a time—delivering the cleaner, cheaper Britain its mission promises.[1][2]
Sunsave has raised $29.0M across 3 funding rounds. Most recently, it raised $17.0M Series A in July 2025.
