MICROMASS LIMITED
MICROMASS LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 03139987, and its current status with Companies House is active. The company was incorporated on 20 December 1995 and lists its registered address as WILMSLOW, United Kingdom. 1 shareholder is on record for MICROMASS 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 21 October 2026.

Four of the 5 officer records shown for MICROMASS LIMITED are current appointments, filed with Companies House. Andrew Schoon (appointed 2009-01-08), Michael Silveira (appointed 2020-02-05), John Lynch (appointed 2020-02-05) and Kathleen White (appointed 2020-02-05) all serve as Director. The remaining 1 record shown (Brian Smith) is a former appointment that has since been resigned.
The register reports 30 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at MICROMASS 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
MICROMASS LIMITED sits 4 levels below its ultimate parent, Waters Corporation, registered in United States. 2 subsidiaries are recorded beneath it, across 1 jurisdiction. The full chain up to Waters Corporation is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by MICROMASS LIMITED's own shareholder record. 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.
