Every active UK company whose primary SIC code sits in the construction section: building construction, civil engineering and the specialised trades. Around 506,400 companies, second only to retail and wholesale. This is the whole industry in one file rather than a region of it, with the SIC description carried alongside the code so a buyer can separate housebuilders from groundworkers from electricians without a lookup table. Registered office location, not site location: a national contractor appears once, at its registered address.

A one-off download of this exact cut, all 503,123 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.
