Audit opinion

Going concern
Affirmed

“The directors have considered the Group's cash flow forecast for a minimum of 12 months from the date of signing these financial statements. The directors of the Company are satisfied after appropriate consultation with the directors of the Group, and review of the forecasts and projections, and taking account of reasonable possible changes in trading performance (including taking into account risks and uncertainties such as the impact of uncertain development sales and the impact of recently established U.S. tariffs on imports (such as solar panels and modules sourced externally to the U.S.)) and current funds available, that the Company is able to operate for at least 12 months from the signing of this annual report and financial statements. For this reason the directors believe that the Company has adequate resources to continue in operational existence and therefore it is appropriate that the Company continues to adopt the going concern basis in preparing this annual report and financial statements.”

Year-on-year

FY2023 → FY2024 · period ending 2024-10-31 vs 2023-10-31

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
