Year-on-year

FY2024 → FY2025 · period ending 2025-05-31 vs 2024-05-31

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

Audit opinion

Going concern
Affirmed

“In assessing going concern, the Board have considered: The principal risks faced by the Group which are addressed within the risk management section of the Annual Report; The financial position of the Group including forecasts and financial projections; The healthy cash position at 31 May 2025 of £14.5m (2024: £7.2m) and the additional headroom available through the renewal of RCF of £5.0m (2024: £nil) and Economic headwinds with the potential for customers to reassess their priorities, with opportunities postponed or curtailed. Following the above considerations, the directors are satisfied that the Group has adequate financial resources to continue in operational existence for a period of at least 12 months from the date of this report. Accordingly, the going concern basis has been adopted in the preparation of the Annual Report for the year ended 31 May 2025.”
