Audit opinion
Unqualified (clean)
Going concern
Affirmed

“In auditing the financial statements, we have concluded that the directors' use of the going concern basis of accounting in the preparation of the financial statements is appropriate. Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue. The accounts are prepared on a going concern basis as the company acts as a holding company and will continue to hold investments for the foreseeable future. Notwithstanding the fact that the company has net liabilities, it has the continued support of the company's intermediate parent undertaking, Gardline Marine Sciences Limited.”

Year-on-year

FY2023 → FY2024 · period ending 2024-12-31 vs 2023-12-31

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
