Public contracts won
CKR Island Construction Ltd has one public sector contract award on record (2025). Source: Contracts Finder and Find a Tender award notices. For all of them the published figure is a shared or multi-year ceiling (a framework place, a multi-supplier award, or more than a small company could hold alone), so no value is shown. These were matched by the company's exact name because the notice gave no company number.
| Buyer | Contract | Value | Awarded |

| Argyll and Bute Council | Argyll and Bute General Property Maintenance Term Contract | Ceiling, not shown | 18 Nov 2025 |
