Officers
5
The Director of DIPLOMA PLC on record is John Henderson; 5 officers are shown here, filed with Companies House.
The register reports 32 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at DIPLOMA 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 PLC has no recorded parent company — it sits at the top of its own group structure, with 12 subsidiaries recorded beneath it across 3 jurisdictions. 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 12 subsidiaries span United Kingdom, United States, Canada 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. Three of the 12 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
