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.	Energy Systems Catapult UK Battery Industrialisation Centre Automotive research centres, battery and vehicle test facilities and major logistics assets.	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.	Corporate and supply chain finance dominate; venture capital is thin relative to industrial output.	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	West Midlands Investment Zone — Investment Zones	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.	The largest manufacturing base in the UK by employment, automotive and electrification engineering, rail and mobility research, and a young, large working-age population.	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.	Ownership of the value in electrified vehicles: battery, power electronics and software increasingly sit outside the region and outside the UK. Innovation-active SME supply chains are under-capitalised.	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.	Midlands manufacturing paired with battery and power electronics research, North East battery production and Coventry testing capability as a single electrification value chain.	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 region's transition depends on owning the new value in a vehicle rather than assembling someone else's. The proposed Midlands zone focuses on batteries, power electronics and software.	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.
