Summary

The Great British Energy (GBE) Supply Chain Fund: Offshore Wind and Networks (the Fund) will award up to £300 million in capital grant funding to build UK manufacturing capacity for key constrained components in offshore wind and enabling electricity networks sectors. The grant funding must be used to construct new or extend existing manufacturing facilities in the UK.

Growth in demand for offshore wind and electricity networks components is outpacing supply chain capacity, resulting in bottlenecks, longer lead times, higher project costs and project delays. This risks delaying critical projects and risking the UK’s renewable energy ambitions. The Fund will target investment towards the most constrained offshore wind and electricity networks components to address critical supply chain constraints and enhance supply chain security in the UK.

The Fund’s application window opened on 11 December 2025 and will close 10 December 2026 (or earlier if the Fund's budget is fully allocated). Grant funding must be drawn down between April 2026 and March 2030.

Eligibility

The eligibility criteria includes: 

  • The applicant must be a company registered under the Companies Act 2006 at the point of submitting a full application.

  • All areas of the UK are eligible for funding, subject to Windsor Framework considerations.

  • Funding must be used to construct new or extend existing manufacturing facilities in the UK.

  • The applicant must confirm that eligible costs will not facilitate the relocation of existing production activities within the UK.

  • The project (when completed) must primarily produce one or more of the "Critical Components" (the Fund's eligible components).

  • The list of eligible components includes: mooring and anchoring, blades, nacelles, towers, monopiles, transition pieces, HVDC cables, HVAC cables (incl. Dynamic), power transformers (AC and DC), HVDC converter stations, switchgear, reactive power management and control systems.

  • Eligible costs must be capital expenditure (CapEx) directly related to the project with a limited scope including:

    • buildings, production equipment and machinery;

    • any associated infrastructure that facilitates delivery and is linked to the specific product being manufactured; and/or

    • research and development costs associated with the manufacturing facility (provided that the grant must also be for construction of those relevant facilities).

  • Eligible costs do not include operating expenditure (OpEx), costs related to land purchase or property transactions, associated service and maintenance agreements, embedded warranty costs, or interest costs.

  • A project is only eligible for grant funding via this Fund if the grant funding is necessary for the project to proceed – i.e. the project has a genuine case for assistance.

 Please see the Guidance document for the full list of eligibility criteria and details.

Objectives

The Fund has two leading objectives and a sub-objective: 

• Primary objective: Increase UK manufacturing capacity of key constrained offshore wind and electricity network components. 

• Secondary objective: Create and support new and existing jobs in the UK, including in industrial clusters.

• Sub-objective: Promote more resilient and sustainable means of production by encouraging investment in shorter or greener supply chains
