Matching uses organisation identifiers where publishers provide them, falling back to name and address. Records are never combined on address alone, because one shared-service postcode carries 244 different organisations. how this works
where these figures come from
Every figure on this page is derived from notices published by Contracts Finder, Find a Tender, Public Contracts Scotland and Sell2Wales, under the Open Government Licence v3.0. The corpus runs from 17 Dec 2014 to 12 Sept 2026 and is refreshed from the publishers' own APIs through the working day.
Records are combined into one organisation on identifiers where publishers provide them — a Companies House number, a GB-PPON supplier id — and on exact normalised name and address where they do not. Never on address alone: one shared-service postcode carries 244 unrelated organisations. The 9 published records behind this page are listed above exactly as filed, so any merge can be checked.
Counts are of contracting processes, not published notices: a tender and its award notice are one contract, and are counted once. Values are medians, never totals, and exclude framework ceilings — a ceiling states a spending limit shared across every supplier on the framework, so adding them together produces a number no one ever spent. sources and coverage · how matching works
