Public contracts won
WQS Wonderseal Ltd has 7 public sector contract awards on record; the ones with their own published value total £2.4M, from 2022 to 2026. Source: Contracts Finder and Find a Tender award notices. For 5 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.
