How these figures are worked out
- The last 12 months: award notices published from 9 November 2025 to 8 November 2026, each contract counted once however many suppliers or rows it has. The same window is used everywhere on this page.
- Year on year: Its published contract awards were falling but rose in the last year. Contracts by publication date in the 12 months to 8 Nov 2026 and the two years before it, oldest first: 19, 9 and 11. A change of more than 15% counts as a rise or fall; each year needs at least 5 contracts.
- 2 contracts end in the next 6 months: Published end dates between 8 November 2026 and 8 May 2027, each contract counted once.
- Has won public contracts every year since 2021: At least one contract in every calendar year from 2021 to 2026, by award date (or publication date where the award date is later). Our records begin in 2021.
- Won work from 2 new buyers in the last 12 months: Buyers with a contract awarded to it and published since 9 November 2025, and none before. Counted by organisation, not by spelling.
- Since 2021: these figures count published award notices from January 2021 onward, the point at which this database begins, and are comprehensive only from 2023. Contracts awarded before then, and any work not published as a public award notice, do not appear. This is a record of published contracts, not of turnover.
- Most recent award: recorded 14 Sept 2026 (7 weeks ago).
