Audit opinion

Going concern
Affirmed

“Despite this, the Company has net current liabilities largely due to funding from other UK Companies at the time of acquisition of the Company's investments. There are no formal agreements in place and therefore these liabilities are current. However, Atkins Réalis Group Inc. has given an undertaking to the directors of the Company that it will provide the necessary financial support for the Company to pay its debts as and when they fall due for a period of at least 12 months from the approval of the financial statements. An assessment of Atkins Réalis Group Inc s ability to support its subsidiaries has been done and the directors are satisfied that it has the financial ability to do this. It is on this basis that the directors have concluded that it is appropriate to adopt the going concern basis in preparing the 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
