Every active UK company whose main declared activity is architectural activities. Around 17,000 companies. SIC class 71111. THE CAVEAT THAT MATTERS: the same caveat as solicitors applies. Practices trading as partnerships are not on the company register at all, so this is the incorporated share of the profession rather than the whole of it, and it is not the ARB or RIBA register, which are held separately and govern who may use the title. Urban planning and landscape architecture sit under 71112 and are not included. CAD and BIM software, professional indemnity, specification products and recruitment sell into this list.

A one-off download of this exact cut, all 17,136 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.
