Public contracts won
PHD Building Contractors 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 |
|---|---|---|---|
| City & County of Swansea | Framework Agreement for Housing Renewals & Adaptations Framework Lots A1, A2, B & C | Ceiling, not shown | 30 Jan 2023 |
