JLT GROUP HOLDINGS LIMITED
JLT GROUP HOLDINGS LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 01679424, and its current status with Companies House is active. The company was incorporated on 18 November 1982 and lists its registered address as London, United Kingdom. 1 shareholder is on record for JLT GROUP HOLDINGS 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 6 November 2026.

Three of the 5 officer records shown for JLT GROUP HOLDINGS LIMITED are current appointments, filed with Companies House.

The register reports 57 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at JLT GROUP HOLDINGS 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
JLT GROUP HOLDINGS LIMITED sits 5 levels below its ultimate parent, Marsh & McLennan Companies, Inc., registered in United States. 15 subsidiaries are recorded beneath it, across 7 jurisdictions. Immediately above JLT GROUP HOLDINGS LIMITED is CALM TREASURY HOLDINGS LIMITED, holding 100% as filed in JLT GROUP HOLDINGS 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 15 subsidiaries span United Kingdom, China, United States, Indonesia, Malta, Canada, and 1 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. One of the 15 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
