ANALYTICAL SECTOR DISTRIBUTION · HTML TABLE AND SCRIPT-FREE SVG SHARE THE SAME ROWS

Classification never becomes camouflage.

An unmapped or absent two-digit CPV division remains unclassified. It is not pushed into the nearest-looking analytical sector by title language.

SUGGESTED CITATION

Achmed Esser (2026), Covered UK public procurement release — 2026-09-04, https://achmedesser.com/data/uk-public-procurement/releases/2026-09-04/

METHOD IN THIS RELEASE

Four rules before interpretation.

currency
Tender and award values remain separate. Only positive structured amounts explicitly labelled GBP are included; no conversion or missing-value inference is performed. Each source amount is normalised to the nearest penny with decimal half-up arithmetic before aggregation, and every displayed sector partition must reconcile to the headline. Multiple awards in the latest retained award-bearing release are summed once per notice identity. Three or more effectively identical rows are treated as one repeated procurement-level framework value rather than multiplied by the row count.
deduplication
OCDS releases remain countable as releases. Notice-level measures group them by OCID where supplied and never add the same lifecycle value repeatedly.
lifecycle
Planning/tender and award are independent flags over the same notice identity, so lifecycle measures may overlap.
quality gate
Both official source runs must complete, exhaust cursor pagination and cover the entire closed day before the release is frozen.
  • This is covered official-source activity, not a census of every UK procurement route.
  • Publication timestamps describe notices and releases, not the date work begins or money is spent.
  • Tender and award values are separate measures and can describe different commercial concepts or lifecycle moments.
  • The displayed sectors are analytical groupings derived from two-digit CPV divisions; they do not replace the source classification.
  • A notice can carry several CPV codes; the first retained structured code supplies the mapped analytical sector while the full code list remains in the private typed record.
  • No supplier-contact or personal-contact fields are published.
