The UK government is on a mission to make the UK a clean energy superpower. The creation of Great British Energy is central to that vision, alongside supporting businesses in the clean energy supply chain.
As demand for renewables infrastructure rapidly increases, supply chain constraints are creating delays, longer lead times, and cost pressures. This fund is designed to tackle these bottlenecks by supporting the construction and expansion of UK-based manufacturing facilities.
What is the Great British Energy (GBE) Supply Chain Fund?
The Great British Energy (GBE) Supply Chain Fund is a £300 million UK capital funding programme running throughout 2026. It is available to businesses constructing new, or extending existing, manufacturing facilities in the UK for offshore wind and electricity network components.
The fund is designed to strengthen domestic manufacturing capacity for critical offshore wind and electricity network components, including: mooring and anchoring, blades, nacelles, towers, monopiles, transition pieces, HVDC cables, HVAC cables, power transformers, HVDC converter stations, switchgear, reactive power management and control systems.
What does the GBE Supply Chain Fund aim to achieve?
The fund aims to improve supply chain resilience and security to support the UK’s clean energy transition. It will:
- Increase UK manufacturing capacity for constrained clean energy components
- Support faster deployment of offshore wind and grid infrastructure
- Build resilient, shorter, and greener supply chains
- Drive job creation and regional economic growth
Which businesses are eligible?
There are several requirements that applicants must meet. Businesses should:
- Be a company registered under the Companies Act 2006.
- Operate in the private sector.
- Deliver projects within the UK (all UK regions are eligible).
Additionally, applicants must confirm that eligible costs will not facilitate the relocation of existing production activities within the UK.
Which projects are eligible?
Eligible projects must focus on building new, or expanding, existing UK manufacturing facilities for the manufacture of critical offshore wind or electricity network components.
Eligible CapEx costs include: buildings and infrastructure; production equipment and machinery; supporting infrastructure linked to manufacturing activity, and related R&D costs associated with the facility build. Ineligible costs include operating expenditure, land purchase, maintenance costs and financing costs.
How to apply
Applications must be submitted online via the Great British Energy online application portal. The fund is open until 10 December 2026, though it may close earlier if the fund is fully allocated. It is being administered across four funding rounds, as follows:
- Round 1 – open 11 December 2025 – 31 March 2026
- Round 2 – open 1 April 2026 – 30 June 2026
- Round 3 – open 1 July 2026 – 30 September 2026
- Round 4 – open 1 October 2026 – 10 December 2026
Given the potential for the fund to close before 10 December, it is recommended that applications for eligible projects are submitted as soon as possible. If you require support to meet the deadline, we can help.
