FIRST HYDRO COMPANY
Company number 02444277 · Monitor this company
Executive summary
First Hydro Company presents a broadly positive compliance and operational picture, with no filing defaults, an active status, a substantial share capital, and a strong controlling shareholder. However, the absence of financial statement data in this extract prevents a definitive assessment of solvency or liquidity, and its private unlimited structure introduces a notable liability consideration. Investors should prioritise access to the full audited accounts and a legal review of the company’s unlimited liability arrangements before any commitment.
