Public contracts won
C.K. Contracts Limited has one public sector contract award on record (2023). 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 |

| South Ayrshire Council | CE-30-23 - Minor Works Framework Agreement | Ceiling, not shown | 8 Nov 2023 |

Filing notes for civil engineering contractors
