SELLAFIELD LIMITED
SELLAFIELD LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 01002607, and its current status with Companies House is active. The company was incorporated on 16 February 1971 and lists its registered address as Warrington, United Kingdom. 2 shareholders are on record for SELLAFIELD 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.

Group Structure
SELLAFIELD LIMITED sits 3 levels below its ultimate parent, Prime Minister's Office, registered in United Kingdom. 1 subsidiary is recorded beneath it, across 1 jurisdiction. Immediately above SELLAFIELD LIMITED is NUCLEAR DECOMMISSIONING AUTHORITY, holding 100% as filed in SELLAFIELD 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 1 subsidiary spans 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.
