Shareholders of Walsh Mechanical Engineering Limited
Walsh Mechanical Engineering Limited has one disclosed shareholder on record with the Companies Registration Office: Walsh Mechanical Engineering Holdings Limited (Irish company number 468929), which holds the entire issued share capital of 100 Ordinary shares of EUR2.00 each, equivalent to a 100% direct holding. This shareholding was verified as at 31 December 2024. No individual shareholders are disclosed for this company, consistent with Ireland’s CRO practice of recording corporate shareholders without requiring disclosure of the ultimate natural-person owner in the standard company filing.
Ultimate beneficial ownership
No verified ultimate beneficial owner is identified for Walsh Mechanical Engineering Limited. The disclosed shareholder, Walsh Mechanical Engineering Holdings Limited, is itself a corporate entity; CRO-linked group data indicates it is in turn connected to Valentdale Limited (Irish company number 594960), but no filing confirming a natural-person beneficial owner at the top of this chain, nor the ownership percentage between Walsh Mechanical Engineering Holdings Limited and Valentdale Limited, was located. An effective UBO percentage therefore cannot be calculated.
Data availability
Shareholder information for Walsh Mechanical Engineering Limited is major-shareholders-only: the immediate corporate shareholder and its holding percentage are disclosed, but no natural-person UBO information is publicly available through the CRO for this entity.

Group Structure
Group structure of Walsh Mechanical Engineering Limited
Walsh Mechanical Engineering Limited is not an independent company: it is a verified direct, wholly owned (100%) subsidiary of Walsh Mechanical Engineering Holdings Limited (Irish company number 468929). CRO-linked group data identifies Valentdale Limited (Irish company number 594960) as the entity above Walsh Mechanical Engineering Holdings Limited in the ownership chain, though the ownership percentage between these two companies is not disclosed, so Valentdale Limited cannot be confirmed as the ultimate parent with a calculated effective percentage. Two verified sister companies, sharing the same immediate parent, were identified: Walsh Facilities Management Limited (Irish company number 484266) and Walsh Electrical Engineering Limited (Irish company number 446477). All identified group entities are registered in Ireland. This structure is broadly consistent with the Walsh Group trading name used on the company’s own website.
