NATIONAL GRID INTERCONNECTOR HOLDINGS LIMITED
NATIONAL GRID INTERCONNECTOR HOLDINGS LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 08169384, and its current status with Companies House is active. The company was incorporated on 6 August 2012 and lists its registered address as London, United Kingdom. 1 shareholder is on record for NATIONAL GRID INTERCONNECTOR 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 9 October 2026.

Group Structure
NATIONAL GRID INTERCONNECTOR HOLDINGS LIMITED sits 3 levels below its ultimate parent, NATIONAL GRID PLC, registered in United Kingdom. 7 subsidiaries are recorded beneath it, across 1 jurisdiction. Immediately above NATIONAL GRID INTERCONNECTOR HOLDINGS LIMITED is NATIONAL GRID HOLDINGS ONE PLC, holding 100% as filed in NATIONAL GRID INTERCONNECTOR HOLDINGS LIMITED's own shareholder record with Companies House. NATIONAL GRID PLC 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 7 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. One of the 7 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
