Audit opinion
Unqualified (clean)
Going concern
Affirmed

“The directors have assessed the Group's ability to continue in operational existence for the foreseeable future and for at least one year from the date of these financial statements. Forecasts and projections based on the approved budget and a further outlook were used as the basis for the going concern modelling. Geo-political uncertainty affecting the world economy has been factored into determining impacts on supply chains, inflation, and market stability. Business resilience stress tests were undertaken to determine multiple revenue scenarios for 2025 and beyond, including a possible worst-case outcome commencing from February 2025 onwards. These Group forecasts and projections indicate that the Group can generate sufficient liquidity to continue in operational existence for the foreseeable future. In 2024 the Group did not utilise any of the available treasury and funding facilities. At the Balance sheet date, the Group had no borrowings and a healthy bank balance. The liquidity position has remained strong since the year end and the directors consider that the present position coupled with available facilities offer sufficient headroom to cover the cash flow risks from considered possible future uncertainties. For these reasons, we continue to adopt the going concern basis in the preparation of these 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
