ATRIUM UNDERWRITERS LIMITED
ATRIUM UNDERWRITERS LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 01958863, and its current status with Companies House is active. The company was incorporated on 14 November 1985 and lists its registered address as London, United Kingdom. 2 shareholders are on record for ATRIUM UNDERWRITERS 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 13 October 2026.
