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.	Digital Catapult Connected Places Catapult Cell and Gene Therapy Catapult Level39 University laboratories, teaching hospitals, data centre and compute capacity, and the densest transport network in the country.	Not recorded on the map. Cyber security innovation centre, composites and aerostructures manufacturing and agri-food research facilities.
Capital	Public and corporate capital dominate; venture funding is limited by capital intensity.	London venture and growth capital ecosystem Venture, growth and public market capital at a scale unmatched elsewhere in Europe, plus corporate venture arms and international investors with UK offices.	A small local venture base supported by public co-investment; growth capital typically comes from Dublin, 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.	Four research-intensive universities, the deepest venture and growth capital pool in Europe, financial regulators, the largest concentration of applied AI companies in the UK and a global-scale creative production economy — all within one travel-to-work area.	Cyber security research and commercialisation of international standing, aerospace and composites manufacturing, agri-food research and a fast-growing software sector.
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.	Circulation. Capital, talent and corporate demand concentrate in London rather than flowing outward, so capability elsewhere in Britain competes for attention with opportunities on the investor's doorstep. Cost also pushes production and scale-up activity out without a route back in.	Scale-up capital and market access. Companies reach a ceiling and are acquired, and dual-market access advantages are under-exploited commercially.
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.	London as the demand and capital node of a national network: investors, corporate buyers and regulators deliberately connected to complementary manufacturing, materials and energy capability in the North, Midlands, Scotland and Wales.	Belfast cyber capability connected to UK defence and financial services demand, and composites manufacturing connected to Bristol and Midlands aerospace supply chains.
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.	London's problem is not capability, it is direction of travel: capital and talent gravitate here rather than circulating. The proposed London zone focuses on using that density to fund and buy from capability elsewhere in Britain.	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.
