    As reported · 2 May 2025

Managed funds acquired the remaining 50%, increasing their UK holding to 100%. The founders retained full ownership of the international business. The percentage applies to the acquired UK business and must not be extended to every international Island Green Power operation. This is selected ownership evidence, not a complete legal parent or shareholder register. Headquarters and parent incorporation have not been separately verified; the location of operations is not treated as proof of either. [1]

03 / The figures, with context

What does it report in UK tax?

The ownership review has not established a dated UK cash corporation-tax payment. Fund investors, operating businesses and property vehicles can have different reporting scopes; no amount is inferred from the investment disclosure.

United KingdomNot yet verified

UK corporation tax paid

Not yet verifiedCash payment

Island Green Power · UK reporting scope not verified
Annual reporting period not yet verified

The cited sources establish investment or portfolio information, rather than a dated UK cash payment. The relevant UK tax-paying entity, filed financial period and cash corporation-tax payment have not been separately reconciled in this review. Not verified does not mean that no tax was paid. [1]

These figures have different scopes. They should not be added together or used as a like-for-like tax ranking.
