Companies House names the individuals with significant control and this site does not repeat them. What matters here is who controls the manager and by how much, and that is filed above in full. A controller that is itself a company keeps its name, because that is a link in an ownership chain rather than a person. The register is one click away if you need the names.
What the SEC filings add
Basalt Infrastructure Partners Llp is the SEC registered adviser matched to this firm. The regulatory assets below belong to that entity rather than to the whole business, and for a British house that is frequently a subsidiary. Treat it as a filed figure about a registration, not as the size of the firm.

Where this comes from
UK record: Companies House, company OC363892, read through its public API. Assets and funds: Form ADV. The two were matched by name, so the company number is shown above for checking rather than asserted: if it is the wrong entity, the link will say so plainly.
