IRON MOUNTAIN (UK) PLC
IRON MOUNTAIN (UK) PLC is a Public Limited Company registered in United Kingdom under 01478540, and its current status with Companies House is active. The company was incorporated on 11 February 1980 and lists its registered address as Lutterworth, United Kingdom. 2 shareholders are on record for IRON MOUNTAIN (UK) 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 20 October 2026.

Nicholas Ford (appointed 2021-01-08) serves as Director; John Virgo (appointed 2020-05-18) serves as Company Secretary.

Management authority at IRON MOUNTAIN (UK) 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
IRON MOUNTAIN (UK) PLC sits 4 levels below its ultimate parent, Iron Mountain Incorporated, registered in United States. 6 subsidiaries are recorded beneath it, across 4 jurisdictions. Immediately above IRON MOUNTAIN (UK) PLC is IRON MOUNTAIN EUROPE (GROUP) LIMITED, holding 100% as filed in IRON MOUNTAIN (UK) PLC's own shareholder record with Companies House. Iron Mountain Incorporated sits further up the chain, a link derived by walking shareholder filings across jurisdictions rather than stated in a single document. 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 6 subsidiaries span United Kingdom, Morocco, Cyprus, 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. One of the 6 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
