DIASORIN LIMITED
Registration details
Company overview
DIASORIN LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 01993990, and its current status with Companies House is active. The company was incorporated on 28 February 1986 and lists its registered address as DIDCOT, United Kingdom. 1 shareholder is on record for DIASORIN 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 8 November 2026.
