About this data
- One profile per authority. Different spellings and registration numbers of the same body are merged into this profile. It includes tenders the authority ran for other bodies and tenders run on its behalf; spend is credited to the body that pays.
- Values are published values. Award values are what the authority published, excluding VAT and framework ceilings. They are not a budget or total spend.
- Contract end dates. 579 of 634 published contracts have an end date; 11 of those are estimated as the signature (or publication) date plus the published duration and are marked “estimated”. They feed “Contracts ending”, the same rule as the retender radar. Published values in that list come from either source; Contracts Finder figures are shown as published and stay out of this profile’s money totals.
- Source. Official UK public procurement notices (Find a Tender and Contracts Finder), reused under the Open Government Licence v3.0, updated through the day and rebuilt nightly. Not every figure uses both feeds, and each one shows how many records it rests on: see the methodology. Spotted something wrong? Tell us.
