Audit opinion
Unqualified (clean)
Going concern
Affirmed

“The Company meets its day to day working capital requirements through cash pooling arrangements with the group companies. The Directors' expectation is that this facility will be available for the foreseeable future. There are no other banking facilities that the Company is reliant upon. The immediate parent (Alcatel Submarine Networks SAS) undertaking has expressed its willingness to provide financial support to Alcatel Submarine Networks UK Ltd for the period of 12 months from the signing of Financial Statements by the auditors. The Directors have performed appropriate procedures to ensure the parent company has the ability to provide support. Therefore, the Directors have reasonable expectation that the Company has adequate resources to continue in operational existence for the foreseeable future. Thus, the Directors continue to adopt the going concern basis in preparing the annual report and financial statements.”

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
