About this data
- Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
- 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. 107 of 138 published contracts have an end date; 4 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.
- Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.
