BIOCOMPOSITES LIMITED
BIOCOMPOSITES LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 03291943, and its current status with Companies House is active. The company was incorporated on 13 December 1996 and lists its registered address as Newcastle, United Kingdom. 1 shareholder is on record for BIOCOMPOSITES 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 22 October 2026.

Shareholders
1
One shareholder is currently on record for BIOCOMPOSITES LIMITED, held on the Confirmation Statement (CS01), filed under the Companies Act 2006.

Because the shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Officers
5
The Director of BIOCOMPOSITES LIMITED currently on record is Jonathan Mahoney; five officers are currently on record for BIOCOMPOSITES LIMITED, filed with Companies House.
The register reports 18 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at BIOCOMPOSITES 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
BIOCOMPOSITES LIMITED sits 8 levels below its ultimate parent, CALCIUM TOPCO LIMITED, registered in United Kingdom. 2 subsidiaries are recorded beneath it, across 3 jurisdictions. The full chain up to CALCIUM TOPCO LIMITED is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by BIOCOMPOSITES 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, Argentina, India jurisdictions, 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.
