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: £13m 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 2 of 20 awards; 1 end within 18 months.
  • Each figure’s own method and sample is behind its ; the long form is on Methodology.
  • Never shown: contact details, reliability or payment scores, affiliations, predicted wins.
