KELIX BIO LIMITED
KELIX BIO LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 12435511, and its current status with Companies House is active. The company was incorporated on 31 January 2020 and lists its registered address as London, United Kingdom. 1 shareholder is on record for KELIX BIO 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.

Officers
5
Four of the 5 officer records shown for KELIX BIO LIMITED are current appointments, filed with Companies House. Paul Andrews (appointed 2024-09-19), Hamad Almarzooqi (appointed 2024-09-19) and James Harper (appointed 2025-10-24) all serve as Director; Csc Cls (uk) Limited (appointed 2020-01-31) serves as Company Secretary. The remaining 1 record shown (Ahmed Almazrouei) is a former appointment that has since been resigned.
The register reports 13 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at KELIX BIO 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
KELIX BIO LIMITED sits 1 level below its ultimate parent, MUBADALA BIO LIMITED, registered in United Arab Emirates. 2 subsidiaries are recorded beneath it, across 1 jurisdiction. Immediately above KELIX BIO LIMITED is MUBADALA BIO LIMITED, holding 100% as filed in KELIX BIO 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. Two of the 2 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
