Audit opinion

Going concern
Affirmed

“The Directors' have stress tested the forecasts for the remainder of 2025 and until 31 December 2026 noting the most significant factor impacting the cash inflows for the Company is the level of revenues being generated. These stress tests show that, without any management actions to mitigate costs, a fall in forecast revenues of more than 20% would be required over 12 months from the date of approval of these financial statements for the Company to run out of liquid funds. This fall in revenues represents a reduction on forecast revenues for the next 12 months as well as a reduction on actual and forecast revenues for the year ended 31 December 2025. However, the Directors would not tolerate such a fall in revenue without taking further measures to reduce costs in the business. The Directors' are aware of the recent tariff increases but the impact is still under evaluation. On the basis of their assessment, including the factors detailed above, the Directors have concluded it is appropriate for the Company's 2024 financial statements to be prepared on a going concern basis. Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the company's ability to continue as a going concern for a period through until 31 December 2026.”

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
