Public contracts won
Iz Energy Services Ltd has 6 public sector contract awards on record; the ones with their own published value total £355K, from 2019 to 2026. Source: Contracts Finder and Find a Tender award notices. For 4 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. 3 of these were matched by the company's exact name because the notice gave no company number.
