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	Not recorded on the map. Naval and maritime engineering facilities, photonics research centres and port infrastructure.	Harwell Science and Innovation Campus Diamond Light Source Satellite Applications Catapult National laboratory campus facilities, quantum fabrication and metrology capability, and clinical research infrastructure.	Energy Systems Catapult UK Battery Industrialisation Centre Automotive research centres, battery and vehicle test facilities and major logistics assets.
Capital	Prime contractor supply chain finance and public programmes rather than venture capital.	University-linked funds and specialist deep tech investors, with London capital an hour away.	Corporate and supply chain finance dominate; venture capital is thin relative to industrial output.
Government programmes	Solent Freeport — Freeports	No place-based designation recorded.	West Midlands Investment Zone — Investment Zones
What exists	Maritime, naval and defence engineering, marine autonomy, photonics research and a major port and logistics complex.	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.	The largest manufacturing base in the UK by employment, automotive and electrification engineering, rail and mobility research, and a young, large working-age population.
What's missing · UKIZ interpretation	Routes for smaller innovators into defence and maritime procurement, and a civil market for capability developed for defence customers.	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.	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.
What could connect · UKIZ interpretation	Marine autonomy and photonics connected to Plymouth marine capability, Bristol robotics and offshore energy operations — the same technologies serving defence, energy and shipping.	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.	Midlands manufacturing paired with battery and power electronics research, North East battery production and Coventry testing capability as a single electrification value chain.
UKIZ relevance	Marine autonomy is where defence, robotics and clean energy meet. The proposed Cornwall & Devon marine mission connects to this capability directly.	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.	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.
