An independent map of UK semiconductor companies, capabilities and regional clusters, for overseas suppliers, partners, investors and acquirers researching the UK sector.
Government context: the 2026 DSIT Semiconductor Sector Study estimates 703 semiconductor-related UK companies — 295 Dedicated and 408 Diversified. That is a separate dataset from the Semiconductor.co.uk index.
Explore UK companies by capability, technology and cluster to identify potential technology, supply-chain and commercial partners — across design and IP, fabrication, compound semiconductors, photonics, RF / microwave, packaging, test, equipment, materials, distribution, manufacturing support and device integration.
Understand UK semiconductor companies, technology areas, regional concentrations, capability strengths, emerging businesses, and the investment and policy context. The index records what companies do; it does not indicate whether any company is raising capital.
Use the Semiconductor.co.uk industry map to understand UK semiconductor companies, technologies, capability areas and regional concentrations relevant to strategic acquisition research. The Company Index is an industry map, not a list of businesses for sale.
For corporate innovation and venture teams: semiconductor IP, advanced chip design, compound semiconductors, photonics and silicon photonics, sensors and MEMS, quantum devices, RF technologies, advanced manufacturing and specialist equipment — drawn only from published records.
The largest capability areas in the public index, by number of mapped companies. Each opens the Company Index already filtered.
The 12 recognised UK clusters, with public company counts from the index. See the cluster overview for each region's specialisms.

The Government's 2026 sector study estimates 703 semiconductor-related companies: 295 Dedicated and 408 Diversified. Semiconductor.co.uk independently maps 375 public companies, of which 231 are fully Verified and 144 Mapped. The two figures come from different datasets and methods.
By number of mapped companies, the largest capability areas in the index are Semiconductor Distribution, Semiconductor Materials, Photonic Semiconductor Devices, Detectors / Imaging Devices, Fab Support / Facilities Engineering, MEMS / Sensors. See the industry overview for the wider context.
Twelve recognised clusters span all four nations, from Scotland and the North East to South Wales, Bristol, Southampton, Cambridge and London. The cluster overview and map above link to each one.
Use the Company Index with its capability, technology and cluster filters, explore individual clusters, or submit an international enquiry below for review.
Visitors can submit an enquiry, which is reviewed by Semiconductor.co.uk. Semiconductor.co.uk provides independent industry research; it does not provide investment advice or brokerage, and does not represent indexed companies.
Tell us what you are looking for — a supplier, partner, technology or research area. Every enquiry is reviewed by a person; nothing is forwarded automatically to any company.
Semiconductor.co.uk independently maps the UK semiconductor industry and does not represent individual indexed companies unless expressly stated.
