England, Wales and Northern Ireland, from Find a Tender (every above-threshold notice since 2021, and everything procured under the Procurement Act 2023 since it came into force on 24 February 2025) and Contracts Finder (procurements begun before then). Scotland publishes on Public Contracts Scotland, which is not covered here; the Scottish notices shown are those that also reached Find a Tender. A contract published on both platforms appears once for each. An end date is the one the notice states, or the term on the tender notice of the same procurement where the award states none; awards that state no term anywhere cannot appear under expiring contracts. A buyer is one spelling of a name: a department that changed its name, or writes it two ways, is two rows under who buys, and one chip, which covers every spelling. A supplier's role is a hint, from its registered SIC code first and the words in its name second.
