Great British Energy (GB Energy) officially came into being on 15 May 2025 through the Great British Energy Act. The creation of the company was one of Labour’s headline election pledges, and when Parliament returned from its summer recess on 2 September, work began to turn the promise into action.
The Vision
GB Energy has been pitched as the mechanism to make Britain a clean energy superpower. Its mission is to cut household bills over time, rapidly scale renewable generation, and build greater energy independence. The targets are ambitious: by 2030 the government aims to double onshore wind, treble solar, and quadruple offshore wind capacity.
What GB Energy Is and Is Not
GB Energy is a publicly owned investor, not a retail supplier. It will not sell electricity directly to households. Instead, it funds clean energy technologies and co-invests alongside private companies. Its budget is supported in part by a windfall tax on oil and gas producers.
Progress So Far
- Partnership with The Crown Estate (July 2024): A first major deal to unlock billions of pounds for offshore wind on the UK seabed out to 12 nautical miles.
- Aberdeen headquarters (September 2024): Aberdeen was selected as the base. The move brings investment but also tension in a city tied to North Sea oil, especially after the windfall tax was extended in November 2024.
- Community funding (March 2025): An Energy Community Fund launched, alongside £200 million for solar across 200 schools and 200 NHS sites. Local Net Zero Hubs received support to guide councils.
- Solar in schools (June 2025): Eleven schools in England completed rooftop solar projects under GB Energy’s programme, with projected savings of £175,000 a year, focused on areas of higher deprivation.
- Local grants (July 2025): £10 million awarded to mayoral authorities to help libraries, fire stations, and care homes install clean energy and reduce long-term bills.
Challenges Ahead
- Can the UK meet the 2030 wind and solar targets given grid, planning, and supply chain constraints?
- How will oil-dependent regions such as Aberdeen transition while protecting jobs and skills?
- Will consumers feel lower bills soon, or only once large projects connect to the grid?
- How will UK policy balance domestic fossil fuel choices with global market pressures?
Looking Forward
Four months on, GB Energy has moved from concept to delivery. Partnerships are in place, funding is flowing, and early community projects are underway. The priority now is scale: turning early wins into nationwide capacity, measurable bill savings, and resilient local economies. GB Energy is a bold step toward a cleaner system, and the next year will show whether momentum can be maintained.
