Significant events
- “an impairment of £2,935,599 was identified this year. This valuation reflects the directors' best estimate and it is inherently sensitive to changes in assumption of actual performance of the business. The valuation is based on substantial decline in the fair value of the price per share based on a refinancing transaction that was completed in July 2024”
- “As at 31 January 2025 the company had no commitment (2024: nil).”
Auditor, going-concern and subsidiary information is drawn from the narrative of the latest annual accounts. About these numbers

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
