UK Castings & Forgings Bill of Works
Published by the Offshore Wind Growth Partnership and the Cast Metals Federation
The UK's offshore wind pipeline will require more than two million tonnes of castings and forgings between 2026 and 2050.
Yet much of this demand is currently met through global supply chains.
Commissioned by the Offshore Wind Growth Partnership and the Cast Metals Federation, the UK Castings & Forgings Bill of Works provides the first detailed assessment of offshore wind demand for cast and forged components alongside a comprehensive review of UK capability.
The independent report identifies where UK manufacturers are already supplying the sector, where existing capability could unlock growth opportunities, and where future investment could help secure greater UK content across offshore wind supply chains.
Key findings
Within a market worth approximately £36 billion, more than 2 million tonnes of castings and forgings will be required across the UK offshore wind pipeline by 2050.
Today, UK manufacturers operate in markets representing around 8% of demand, but existing capability could increase participation to approximately 14%, with strategic investment creating the potential to reach 37% of future demand worth £14.6 billion in GVA.
Unlocking that growth could support around 26,000 new jobs, protect cross-industry capability and retain industrial capability and capacity in the UK.
A bigger role for UK manufacturing
The report showcases the strength of the UK's castings and forgings sector, including established offshore wind suppliers and businesses with the capabilities across castings, forgings, specialist steels, cable infrastructure and future turbine component production to expand into new markets.
It analyses 63 individual cast and forged components used across offshore wind projects, including turbines, foundations, cables, substations and floating wind mooring systems looking at:
Current UK activity
Current UK activity in fasteners, cable protection systems, sacrificial anodes and specialist cast components.
Existing capability
Existing capability that could be deployed into smaller turbine castings, electrical systems, mooring components and other offshore wind applications.
Future opportunities
Future opportunities requiring targeted investment, including forged rings, hub castings, nacelle structures and drivetrain components.
Regional economic impact
Regional economic impact of the UK castings and forgings sector in the context of offshore wind with particular focus on areas like the West Midlands, South Yorkshire and the North East, as well as Scotland and Wales.
Aligned with industrial strategy
The offshore wind sector's Industrial Growth Plan identified the areas where the UK has the greatest opportunity to build competitive domestic supply chains. This report provides the evidence base showing how castings and forgings can support those ambitions.
The findings highlight strong alignment between UK manufacturing capabilities and priority Industrial Growth Plan areas including advanced turbine technology, deepwater foundations, floating offshore wind, electrical systems, moorings and future drivetrain manufacturing.
Most importantly, the report demonstrates that the UK is not starting from scratch. UK foundries and forges are already supplying offshore wind today, providing a platform for future growth, investment and greater UK content across the sector.
