What your business can use it for

Sales prospecting

Find public-sector buyers and live tenders in your category and area — including contracts flagged as suitable for smaller suppliers — so you can chase the work that fits you.

Market analysis

See who wins contracts in your sector, from which buyers and at what value — competitor and market intelligence straight from the public record.

Customer & supplier checks

Check a company's public-contract track record — what they have won, from whom and for how much — before you partner with or supply them.

Works with data you already have

  • Company numbers Company numbers
    Suppliers and buyers registered with Companies House carry a CRN; take the identifier where the scheme is GB-COH and zero-pad to 8 digits
  • Supplier or buyer names Business names
    Match on the named supplier or public-body buyer; expect some cleaning
  • Supplier postcodes Postcodes
    Supplier addresses carry a postcode you can join to any postcode-keyed dataset

How to get it

  • Portal Search notices — Contracts Finder
    No account needed to search or download. Tenders you can bid for and award notices naming the winner, buyer and value.
  • API Contracts Finder API
    Free, no key. Returns notices in the Open Contracting standard for bulk analysis; a daily-file harvest is one common approach.

What's involved in using it

  • It comes as a running stream of daily files — one per day, hundreds of them across a few years — rather than a single download, so covering a period means gathering and combining them all.
  • Each file is very wide and mostly empty, with hundreds of columns, so it has to be trimmed down to the handful that matter before it is workable.
  • The winning supplier's company number — the key to linking a contract to other business data — is only present some of the time and sits among several other kinds of identifier.

Worth knowing before you start

  • Contracts Finder mainly carries lower-value contracts. Higher-value public tenders are published on Find a Tender, held separately — so this is not the whole procurement picture.
  • A supplier's company number only appears where they registered with one; charities and public bodies use other identifiers, so filter to Companies House matches before joining.
  • Notices come in stages — a tender notice advertises the work, an award notice names the winner and value. Use the award notices for who-won analysis.
  • It is published as a running stream of notices, not a single bulk file; a full history means harvesting day by day back to 2015.
  • Public-procurement rules changed in February 2025 and newer notices also appear on a separate Central Digital Platform, not covered here.
