Going concern

Affirmed

“The Group is reliant on financial support from its major trading subsidiary and investors. The Group has net current assets of £9.7m which includes cash of £3.8m but has net liabilities of £5.0m. As explained in note 22 the Group has loan notes which are not due for payment until 1 June 2027. The Company expects support from fellow Group undertakings to continue for the foreseeable future. Demand for the Group's services remains strong and new projects for future delivery continue to be secured. Therefore, based on 18 month projections, the Directors expect the group to have adequate resources to continue in operational existence at current levels with headroom within operating facilities for planned growth in FY26 and FY27.”

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
