Every active UK company whose main declared activity is engineering design for industrial process and production. Around 8,000 companies. SIC class 71121. THE CAVEAT THAT MATTERS: the counterpart to 71122, and the same warning applies in reverse. Firms self-select between the two and a design practice may well be registered as consulting, so treat the pair as one market. Design and simulation software, prototyping, professional indemnity and recruitment sell into this list.

A one-off download of this exact cut, all 8,335 rows and every column shown above, as a CSV file that opens in Excel or Google Sheets. It's a snapshot of the data as it is today. It does not include ongoing updates or API access, neither of which is available yet.
Yes, on request. We can turn on API access for this dataset against your account, and you issue your own key from your dashboard. It returns the same data as the file, over HTTP, in JSON, with the edition date on every response so your systems can tell when there is something new to pull.
It is not a live feed. The data changes when the register is refreshed, roughly monthly, and the API serves whatever the current edition is. Access is arranged per dataset rather than bought from the site, so ask us and we will set it up.
Yes. The preview above is real data, and the 15-row sample download gives you every column so you can check the format and quality first.
Yes. A commercial and internal-business licence is included. Redistribution as-is is restricted; enterprise redistribution rights are available on request.
The price shown includes UK VAT at 20%, so it is the amount you pay with nothing added at the end, and checkout shows the split before you commit. A VAT invoice is raised and emailed automatically when payment goes through, carrying our VAT number and the tax breakdown, so a UK VAT-registered business can reclaim the VAT without asking us for anything.
