About this data
  • Estimates, labelled. The price range, possible competitors and earlier-work matches are our estimates from past awards, not published facts, win chances or price advice. The buyer’s own record and the wider market are shown apart, never mixed.
  • Source. Official UK public procurement notices (Find a Tender and Contracts Finder), reused under the Open Government Licence v3.0, updated through the day and rebuilt nightly. Not every figure uses both feeds, and each one shows how many records it rests on: see the methodology. Spotted something wrong? Tell us.
