Public contracts won
Just Rails Limited has one public sector contract award on record (2024). 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 |
|---|---|---|---|
| Rhondda Cynon Taf CBC | Disabled Adaptations and Repairs Framework (Darf) | Ceiling, not shown | 1 Nov 2024 |
