Public contracts won
Aztech Building Services Limited has 8 public sector contract awards on record; the ones with their own published value total £4.8M, from 2017 to 2023. Source: Contracts Finder and Find a Tender award notices. For 2 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. 4 of these were matched by the company's exact name because the notice gave no company number.
