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.

Companies	South Wales compound semiconductor cluster	Not recorded on the map.	Bristol semiconductor and processor design cluster
Infrastructure	Not recorded on the map. Compound semiconductor fabrication and research facilities, materials and coatings research, production studios.	Advanced Manufacturing Research Centre Nuclear AMRC High Value Manufacturing Catapult centres, nuclear manufacturing facilities and industrial research factories.	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.	Public co-investment, corporate partnership and asset finance rather than venture capital.	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.	One of the strongest applied manufacturing research bases in Europe, covering machining, materials, nuclear manufacturing and factory-scale process development, working directly with industrial customers.	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.	Domestic demand. World-class process capability is often demonstrated for overseas primes, and local SMEs lack the capital to adopt what is proven a mile away.	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.	Applied manufacturing research connected to domestic customers — energy, defence, mobility and medical technology — with procurement used as the connector rather than grants.	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.	The research is world class; the domestic customer base for what it produces is thinner than it should be. The proposed Midlands and Teesside & Humber missions both depend on this capability.	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.
