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 (£150m, ceilings stripped) is a catalogue fact, not spend, and is not shown as a headline.
- Awards on procedures published in the last 24 months: 38 award records on 29 procedures (38 to a single canonical supplier, 0 multi-supplier). 26 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: 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”.
