Public contracts won
Drain Surgeon Services Limited has 2 public sector contract awards on record, from 2021 to 2022. 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.
