DIAMOND LIGHT SOURCE LIMITED
DIAMOND LIGHT SOURCE LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 04375679, and its current status with Companies House is active. The company was incorporated on 18 February 2002 and lists its registered address as Didcot, United Kingdom. 3 shareholders are on record for DIAMOND LIGHT SOURCE 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 5 October 2026.
