Who wins

Suppliers ranked by the number of tenders won, not by money. A supplier on one big framework with many call-offs does not outrank one that won many separate competitions.

Ranked by distinct procedures won on notices carrying this code, then award records · 407 awards to 272 suppliers · the five most frequent winners hold 6% of contract awards in the last 36 months

About this data
  • Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
  • What counts here. Every notice with a CPV code starting 4522. A notice with several codes counts in each sector it names. Notices from 2021 to 23 Oct 2026.
  • Competition. Bids and winners cover the last three years and count each lot as its own contest; frameworks and dynamic purchasing systems are shown apart from ordinary contracts.
  • Why no total spend. Notice estimates often repeat a framework’s ceiling, so adding them up would overstate the market. Typical contract values are shown instead.
  • Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.
