COSTAIN ENGINEERING & CONSTRUCTION LIMITED
COSTAIN ENGINEERING & CONSTRUCTION LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 02440829, and its current status with Companies House is active. The company was incorporated on 7 November 1989 and lists its registered address as London, United Kingdom. 1 shareholder is on record for COSTAIN ENGINEERING & CONSTRUCTION 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 22 September 2026.

One shareholder is currently on record for COSTAIN ENGINEERING & CONSTRUCTION LIMITED, held on the Confirmation Statement (CS01), filed under the Companies Act 2006.

Officers
5
The Director of COSTAIN ENGINEERING & CONSTRUCTION LIMITED on record is John Armitt; 5 officers are shown here, filed with Companies House.
The register reports 40 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at COSTAIN ENGINEERING & CONSTRUCTION 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
COSTAIN ENGINEERING & CONSTRUCTION LIMITED sits 1 level below its ultimate parent, COSTAIN GROUP PLC, registered in United Kingdom. 6 subsidiaries are recorded beneath it, across 1 jurisdiction. Immediately above COSTAIN ENGINEERING & CONSTRUCTION LIMITED is COSTAIN GROUP PLC, holding 100% as filed in COSTAIN ENGINEERING & CONSTRUCTION LIMITED's own shareholder record with Companies House. 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 jurisdiction, 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. Two of the 6 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
