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

Going concern
Affirmed

“The directors have adopted the going concern basis of accounting for the preparation of the financial statements as the Company's ultimate parent company, Harbour Energy plc, has undertaken to directly provide the necessary financial support to the Company, as and when required, to meet all liabilities for a period of 12 months from the date of signing these financial statements. In making their assessment of going concern, the directors have considered the letter of support from Harbour Energy plc and are confident that it has adequate resources to support the Company for 12 months from the date of signing these financial statements.”
