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.

Companies	Bristol semiconductor and processor design cluster	Cambridge semiconductor and processor IP cluster	Northern Ireland aerospace and composites cluster
Infrastructure	National Composites Centre Quantum and robotics laboratories, national composites facilities and aerospace test capability.	Babraham Research Campus Cambridge Science Park University and institute laboratories, genomics and biomedical campus facilities, and semiconductor design capability.	Not recorded on the map. Cyber security innovation centre, composites and aerostructures manufacturing and agri-food research facilities.
Capital	An established angel and seed base with strong deep tech interest; growth rounds usually come from London or the US.	Specialist deep tech and life science funds, university-linked funds, and corporate partners; strong at seed, thinner at growth stage relative to demand.	A small local venture base supported by public co-investment; growth capital typically comes from Dublin, London or the US.
Government programmes	No place-based designation recorded.	No place-based designation recorded.	No place-based designation recorded.
What exists	Semiconductor and processor design, quantum engineering, robotics and autonomous systems, aerospace and composites, and a creative and screen economy of national significance.	Extreme research density for its size: life sciences and genomics, semiconductor and processor IP, engineering biology and AI, with a mature spin-out culture and specialist investors who understand long timelines.	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	Fabrication and volume production capacity to match the design strength, and hardware-friendly capital. Companies scale by moving production abroad.	Ownership retention. Discovery and early company formation work; the Series B onward stage frequently transfers ownership overseas. Laboratory and scale-up space, power and housing also constrain growth.	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	Bristol design capability connected to South Wales compound semiconductor fabrication and to composites and aerospace manufacturing — a western technology corridor with a complete chain.	Cambridge discovery connected to UK manufacturing and biomanufacturing capacity, and to later-stage domestic capital, so that value created here is realised here rather than acquired out of the country.	Belfast cyber capability connected to UK defence and financial services demand, and composites manufacturing connected to Bristol and Midlands aerospace supply chains.
UKIZ relevance	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.	Cambridge produces intellectual property at a rate few places match, and loses ownership of too much of it at Series B. The proposed Oxford–Cambridge zone concentrates on commercialisation and retention rather than on more discovery.	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.
