Data coverage & method
  • Source: Find a Tender OCDS releases; mixed PCR 2015 / Procurement Act 2023 history — no legal-regime label is applied.

  • 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: 28 of 98 published contracts carry a period end; 9 end within 18 months, 4 within 6.
  • Never shown: contact details, predicted winners, payment behaviour, or “who to invite”.
