Going concern
Affirmed

“The financial statements have been prepared on a going concern basis. In adopting the going concern basis the Directors have considered the Company's business activities, together with the main trends and factors likely to affect its future development; performance and position, and the financial position of the Company as at 31 March 2025 and at the approval date of these financial statements, its cash flows, liquidity position and borrowing facilities. The Directors have prepared forecasts up to 31 March 2027, and these forecasts show that the Company is expected to remain profitable and even in a severe but plausible downside scenario the Company is still able to meet its debts as they fall due.”

Auditor, going-concern and subsidiary information is drawn from the narrative of the latest annual accounts. About these numbers

Year-on-year

FY2024 → FY2025 · period ending 2025-03-31 vs 2024-03-31

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
