THORNTON TOMASETTI LIMITED
THORNTON TOMASETTI LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 05888655, and its current status with Companies House is active. The company was incorporated on 27 July 2006 and lists its registered address as London, United Kingdom. 1 shareholder is on record for THORNTON TOMASETTI 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 16 October 2026.

The register reports 29 officers in total, including past appointments, though only the 4 most relevant records are shown here.
Management authority at THORNTON TOMASETTI 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
THORNTON TOMASETTI LIMITED sits 1 level below its ultimate parent, Thornton Tomasetti, Inc., registered in United States. 1 subsidiary is recorded beneath it, across 2 jurisdictions. The full chain up to Thornton Tomasetti, Inc. is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by THORNTON TOMASETTI LIMITED's own shareholder record. 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 1 subsidiary spans United Kingdom, Italy 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.
