Public contracts won
Osmosis Acd Limited has 10 public sector contract awards on record; the ones with their own published value total £1M, 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. 6 of these were matched by the company's exact name because the notice gave no company number.

Filing notes for property development companies
Many property development companies are single-project vehicles. Stock of land and buildings sits on the balance sheet as work in progress until sale, and a company that has finished its project may become dormant rather than close.
