Public contracts won
Clameg Design and Build Ltd has one public sector contract award on record (2021). 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 |
|---|---|---|---|
| The Guinness Partnership Ltd | Guinness Property Contractor Frameworks 1 - Responsive Repairs 2 - Empty Homes | Ceiling, not shown | 17 May 2021 |

Filing notes for building contractors
Building companies often run the Construction Industry Scheme as a contractor, a subcontractor or both. CIS deductions suffered during the year are set against the PAYE bill, and any unrecovered balance at the year end matters when the accounts are drawn up.
