About this data

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 in the buyer chart describe the buyer office, not where the work is delivered or the supplier’s registered address.
Contract end dates. Published on 2 of 23 awards, estimated from the published duration on 13 more (marked “estimated”); those feed “Contracts ending”. 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.
