Data coverage & method
  • Source: Find a Tender OCDS releases; mixed PCR 2015 / Procurement Act 2023 history — no legal-regime label is applied.
  • Counts are procedures (one notice family), not lots. Authority cluster = canonical buyer plus beneficiary and procuring-entity roles.
  • Published procedure values exist on a minority of notices; their lifetime sum (£50m, ceilings stripped) is a catalogue fact, not spend, and is not shown as a headline.
  • Awards on procedures published in the last 24 months: 93 award records on 81 procedures (92 to a single canonical supplier, 1 multi-supplier). 41 values come from the contract record when the award carried none.
  • Bid counts, deadline-to-award, amendments and award-vs-estimate come from the nightly buyer analytics row; each figure’s own method and sample is behind its , the long form on Methodology.
  • Contract end dates: 76 of 85 published contracts carry a period end; 25 end within 18 months, 16 within 6.
  • Never shown: contact details, predicted winners, payment behaviour, or “who to invite”.
