Public contracts won
Prime Build South West Ltd has 4 public sector contract awards on record; the ones with their own published value total £4.5M, from 2020 to 2026. Source: Contracts Finder and Find a Tender award notices. For 1 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. 2 of these were matched by the company's exact name because the notice gave no company number.

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.
