MMC UK GROUP LIMITED
MMC UK GROUP LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 03704258, and its current status with Companies House is active. The company was incorporated on 28 January 1999 and lists its registered address as LONDON, United Kingdom. 1 shareholder is on record for MMC UK GROUP LIMITED, 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 8 October 2026.

Officers
5
Four of the 5 officer records shown for MMC UK GROUP LIMITED are current appointments, filed with Companies House. David Williams (appointed 2007-12-17), Justin Broad (appointed 2018-08-03) and Mark Chessher (appointed 2026-04-09) all serve as Director; Ashton Ramseyer (appointed 2022-10-07) serves as Company Secretary. The remaining 1 record shown (Christopher Lay) is a former appointment that has since been resigned.
The register reports 27 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at MMC UK GROUP LIMITED 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
MMC UK GROUP LIMITED sits 6 levels below its ultimate parent, Marsh & McLennan Companies, Inc., registered in United States. 25 subsidiaries are recorded beneath it, across 9 jurisdictions. Immediately above MMC UK GROUP LIMITED is MARSH & MCLENNAN COMPANIES UK LIMITED, holding 100% as filed in MMC UK GROUP LIMITED's own shareholder record with Companies House. Marsh & McLennan Companies, Inc. 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 25 subsidiaries span United Kingdom, Turkey, Cyprus, Portugal, United States, Luxembourg, and 3 more 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. Seven of the 25 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
