INTERNATIONAL NUCLEAR SERVICES LIMITED
INTERNATIONAL NUCLEAR SERVICES LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 01144352, and its current status with Companies House is active. The company was incorporated on 8 November 1973 and lists its registered address as Warrington, United Kingdom. 1 shareholder is on record for INTERNATIONAL NUCLEAR SERVICES 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 19 October 2026.

Shareholders
1
One shareholder is currently on record for INTERNATIONAL NUCLEAR SERVICES LIMITED, held on the Confirmation Statement (CS01), filed under the Companies Act 2006.

Officers
5
The Director of INTERNATIONAL NUCLEAR SERVICES LIMITED currently on record is Wanda Goldwag; five officers are currently on record for INTERNATIONAL NUCLEAR SERVICES LIMITED, filed with Companies House.
The register reports 50 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at INTERNATIONAL NUCLEAR SERVICES 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
INTERNATIONAL NUCLEAR SERVICES LIMITED sits 3 levels below its ultimate parent, Prime Minister's Office, registered in United Kingdom. 3 subsidiaries are recorded beneath it, across 3 jurisdictions. Immediately above INTERNATIONAL NUCLEAR SERVICES LIMITED is NUCLEAR DECOMMISSIONING AUTHORITY, holding 100% as filed in INTERNATIONAL NUCLEAR SERVICES LIMITED's own shareholder record with Companies House. Prime Minister's Office 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 3 subsidiaries span United Kingdom, France, Japan 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.
