Compare places

Two or three clusters, read side by side across sectors, research, companies, capital, infrastructure, government designations and UKIZ relevance. There is no score and no ranking: British clusters are different from one another, not better or worse than one another.

Infrastructure	Not recorded on the map. Compound semiconductor fabrication and research facilities, materials and coatings research, production studios.	Not recorded on the map. Cyber security innovation centre, composites and aerostructures manufacturing and agri-food research facilities.	National Composites Centre Quantum and robotics laboratories, national composites facilities and aerospace test capability.
Capital	Public and corporate capital dominate; venture funding is limited by capital intensity.	A small local venture base supported by public co-investment; growth capital typically comes from Dublin, London or the US.	An established angel and seed base with strong deep tech interest; growth rounds usually come from London or the US.
Government programmes	Wales Investment Zone designations — Investment Zones	No place-based designation recorded.	No place-based designation recorded.
What exists	The UK's compound semiconductor cluster, combining research, fabrication and supply chain, alongside steel and coatings materials research, and a significant screen production economy.	Cyber security research and commercialisation of international standing, aerospace and composites manufacturing, agri-food research and a fast-growing software sector.	Semiconductor and processor design, quantum engineering, robotics and autonomous systems, aerospace and composites, and a creative and screen economy of national significance.
What's missing · UKIZ interpretation	Design demand. Fabrication capability needs a pipeline of UK customers designing products that use it, and capital patient enough for semiconductor timelines.	Scale-up capital and market access. Companies reach a ceiling and are acquired, and dual-market access advantages are under-exploited commercially.	Fabrication and volume production capacity to match the design strength, and hardware-friendly capital. Companies scale by moving production abroad.
What could connect · UKIZ interpretation	South Wales fabrication connected to Bristol and Cambridge chip design and to defence, automotive and energy customers who currently source overseas.	Belfast cyber capability connected to UK defence and financial services demand, and composites manufacturing connected to Bristol and Midlands aerospace supply chains.	Bristol design capability connected to South Wales compound semiconductor fabrication and to composites and aerospace manufacturing — a western technology corridor with a complete chain.
UKIZ relevance	Compound semiconductors are a genuine national specialism with a fragile ownership base. The proposed Wales mission focuses on keeping the value chain here.	Northern Ireland's position between two markets is a commercial asset that is under-used. The proposed Northern Ireland mission treats it as the organising advantage.	Bristol's design and robotics capability has historically been acquired rather than scaled. The proposed zone concentrates on the capital and customer connections that let companies stay independent.
