How many public sector contracts has ISG Construction Limited won?
110 since 2021, of which 86 were awarded to it as the only named supplier and 24 are shared with other suppliers, usually a place on a framework. This counts award notices published to Find a Tender and Contracts Finder, so it is a record of published awards rather than of total revenue.

Where does this information about ISG Construction Limited come from?

How these figures are worked out
- The last 12 months: award notices published from 8 November 2025 to 7 November 2026, each contract counted once however many suppliers or rows it has. The same window is used everywhere on this page.
- 1 contract ends in the next 6 months: Published end dates between 7 November 2026 and 7 May 2027, each contract counted once.
- No published award in the last 12 months: No award notice published since 8 November 2025 in the notices we hold.
- 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 31 Mar 2025 (1 year 7 months ago).
