Public contracts won
ST Construction Ltd. has 4 public sector contract awards on record; the ones with their own published value total £30K, from 2021 to 2023. Source: Contracts Finder and Find a Tender award notices. For 3 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.

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.
