Public contracts won
J. C. Martin 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 |

| NHS Dumfries & Galloway | NHSDG - Estates & Property - Term Electrical Contractor June 2023 - May 2026 | Ceiling, not shown | 29 May 2023 |

Filing notes for electrical contractors
Electrical contracting companies are often a director plus a van and tools. Most fall within the micro-entity rules, so the accounts filed at Companies House are short, and the CT600 carries the tax detail.
