DIPLOMA HOLDINGS PLC
DIPLOMA HOLDINGS PLC is a Public Limited Company registered in United Kingdom under 00256111, and its current status with Companies House is active. The company was incorporated on 1 May 1931 and lists its registered address as London, United Kingdom. 1 shareholder is on record for DIPLOMA HOLDINGS PLC, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Companies House and was last updated on 28 October 2026.

The register reports 18 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at DIPLOMA HOLDINGS PLC sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
DIPLOMA HOLDINGS PLC sits 1 level below its ultimate parent, DIPLOMA PLC, registered in United Kingdom. 16 subsidiaries are recorded beneath it, across 3 jurisdictions. Immediately above DIPLOMA HOLDINGS PLC is DIPLOMA PLC, holding 100% as filed in DIPLOMA HOLDINGS PLC's own shareholder record with Companies House. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 16 subsidiaries span United Kingdom, Italy, United States jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Eight of the 16 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
