Classification: Partial. Companies House confirms the immediate and ultimate parent at the 75%-or-more banded threshold. TCLARKE PLC’s direct UK subsidiaries are drawn from internally held group-linkage records rather than independently re-verified shareholding filings for each entity; two subsidiaries were spot-checked at Companies House and share TCLARKE PLC’s registered office, consistent with common group administration, but exact ownership percentages for the subsidiaries were not disclosed. Other companies that sit under Regent International Holdings Limited outside this direct chain, including a separate gas and utilities sub-group, were not treated as TCLARKE PLC group companies for this review.
