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.

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.	Harwell Science and Innovation Campus Diamond Light Source Satellite Applications Catapult National laboratory campus facilities, quantum fabrication and metrology capability, and clinical research infrastructure.
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.	University-linked funds and specialist deep tech investors, with London capital an hour away.
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.	A research-intensive university alongside the Harwell campus, one of the largest concentrations of national scientific infrastructure in Britain, spanning space, energy, health and physical sciences, with distinctive quantum, vaccine and space applications strength.
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.	Access. National facilities are heavily used by their own communities; companies without an existing university relationship find the route in unclear. Scale-up space and later-stage capital are also constrained.
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.	Opening national facility access to companies across Britain as shared ecosystem infrastructure, and pairing Oxford quantum and space capability with manufacturing clusters that could produce at volume.
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.	Oxford has infrastructure most countries cannot build. The proposed zone focuses on making that infrastructure accessible to companies that are not spin-outs of the university.
