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	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. Compound semiconductor fabrication and research facilities, materials and coatings research, production studios.
Capital	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.	Public and corporate capital dominate; venture funding is limited by capital intensity.
Government programmes	No place-based designation recorded.	Wales Investment Zone designations — Investment Zones
What exists	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.	The UK's compound semiconductor cluster, combining research, fabrication and supply chain, alongside steel and coatings materials research, and a significant screen production economy.
What's missing · UKIZ interpretation	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.	Design demand. Fabrication capability needs a pipeline of UK customers designing products that use it, and capital patient enough for semiconductor timelines.
What could connect · UKIZ interpretation	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.	South Wales fabrication connected to Bristol and Cambridge chip design and to defence, automotive and energy customers who currently source overseas.
UKIZ relevance	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.	Compound semiconductors are a genuine national specialism with a fragile ownership base. The proposed Wales mission focuses on keeping the value chain here.
