Data coverage & method
- Source: Find a Tender OCDS award and contract releases. An award record is one award × this supplier; a procedure can carry many (panels, call-offs).
- Market observations are awarded lots, or one envelope award when the notice publishes no lot links. Region = delivery ITL1 on the notice, not the supplier’s registered address.
- Authority type: official OCDS UK contracting-authority type when the notice publishes one; otherwise a Tenderline name/id class; otherwise “not classified”. Purchasing hubs with no published type stay unclassified.
- Published value attributable to this supplier alone: £41m across single-supplier awards, framework / DPS ceilings excluded. Coverage is partial and the figure is not turnover, so it is not shown as a headline.
- Contract end dates: published on 1 of 9 awards; 0 end within 18 months.
- Award vs estimate tiers: robust ≥5, moderate 3–4, indicative 1–2 comparable pairs.
- Never shown: contact details, reliability or payment scores, affiliations, predicted wins.
