The UK company register
Every active company in the country, screened against your buy box, then scored for the signs that surface before a business goes to market.
Leave everything unticked to search all sectors. Tick a category to narrow to it, or open one to pick individual SIC codes.
Nothing ticked means the whole UK. Regions are read from the registered postcode, so a company registered at its accountant's office will show there rather than at its yard.
The register never publishes turnover. What it does publish is which accounting regime a company files under, which is the closest honest proxy.
Build it here, or hand over a buy box you have already written.
Choose your criteria on screen, then run them against every active company on the register.
Drop in a filled-in template or your own criteria. We read it and set the buy box for you to check before anything runs.
