Public contracts won
Silwood Facilities Limited has 11 public sector contract awards on record; the ones with their own published value total £442K, from 2016 to 2026. Source: Contracts Finder and Find a Tender award notices. For 7 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.
