Companies House records Imperium Engineering Ltd as a person with significant control (a corporate-kind PSC, i.e. a registrable legal entity / RLE) on 3 UK companies: 1 active and 2 ceased appointments on the live PSC register. Use this page to look up every company where Imperium Engineering Ltd is on file as a beneficial owner above the 25% threshold, to search Imperium Engineering Ltd's appointment history, or to verify control relationships before a KYB / UBO / beneficial-ownership due-diligence call. OpenRegistry by Sophymarine indexes the Companies House PSC bulk feed and cross-links each row to the company's officers, shareholders and filing history. As a corporate-kind PSC, Imperium Engineering Ltd is itself controlled by ultimate beneficial owners further up its own ownership chain; OpenRegistry walks that chain via search_companies + get_shareholders. Different legal entities can share confusingly similar registered names; verify each appointment against the linked company profile on OpenRegistry.
Significant control under the UK Companies Act 2006 (as amended) covers any of: shareholding above 25%, voting rights above 25%, the right to appoint or remove a majority of directors, or significant influence or control exercised by other means. The same concept appears under different names in other jurisdictions: beneficial owner, UBO, ultimate beneficial owner, registered beneficial owner (RBO), bénéficiaire effectif (FR), Reelle Rettighetshavere (NO), raunverulegir eigendur (IS), wirtschaftlich Berechtigte (DE / Transparenzregister). OpenRegistry exposes the live equivalent register for the jurisdictions that publish one publicly. See https://openregistry.sophymarine.com/registries for the per-country coverage matrix.
