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 supplier. Built from award and contract notices that name this supplier; different spellings and registration numbers of the same company are merged into this profile.
- Values are published values. The table mirrors what the notice published: framework ceilings and joint awards are labelled and never counted as this supplier's money, and † marks a value taken from the contract notice when the award published none. Only awards made to this supplier alone count towards its value, excluding VAT. It is not turnover.
- Regions on this page are where the work is delivered, not the supplier’s registered address.
- Contract end dates. Published on 14 of 15 awards, estimated from the published duration on 0 more (marked “estimated”); those feed “Contracts ending”.
- 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.
