Going concern

Affirmed

“The financial statements have been prepared on the going concern basis which the directors believe to be appropriate for the following reasons. The company has net liabilities of £52.0m (2024: £71.5m) and is dependent for its working capital on funds provided to it by Costain Group PLC, the company's ultimate parent undertaking. In determining the appropriate basis of preparation of the financial statements for the year ended 31 December 2025, the directors are required to consider whether the company can continue in operational existence for the foreseeable future. The directors have concluded that after having received an undertaking from Costain Group PLC that for at least 12 months from the date of approval of these financial statements, it will continue to make available such funds as they are needed by the company, it is appropriate to adopt the going concern basis in preparing these financial statements.”

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
