Public contracts won
Angus Mackay & Sons Ltd has 3 public sector contract awards on record, from 2021 to 2026. 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. 2 of these were matched by the company's exact name because the notice gave no company number.

Filing notes for civil engineering contractors
