PLESSEY SEMICONDUCTORS LIMITED
PLESSEY SEMICONDUCTORS LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 04129612, and its current status with Companies House is active. The company was incorporated on 18 December 2000 and lists its registered address as PLYMOUTH, United Kingdom. 1 shareholder is on record for PLESSEY SEMICONDUCTORS 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 18 October 2026.

Management authority at PLESSEY SEMICONDUCTORS 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
PLESSEY SEMICONDUCTORS LIMITED sits 1 level below its ultimate parent, HAYLO LABS LIMITED, registered in United Kingdom. 2 subsidiaries are recorded beneath it, across 1 jurisdiction. Immediately above PLESSEY SEMICONDUCTORS LIMITED is HAYLO LABS LIMITED, holding 100% as filed in PLESSEY SEMICONDUCTORS 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 2 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 2 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
