  Material uncertainty over going concern

  The directors believe, after due and careful enquiry, that the company has sufficient resources for its present requirements and, therefore, consider it appropriate to adopt the going concern basis in preparing the financial statements to 31 March 2025, notwithstanding the material uncertainty discussed below. The Directors are of the opinion that the equity raise and associated refinancings will be concluded but given it has not been committed at the date of the financial statements and its commitment is not within the Directors' control, believe that the risk that they do not conclude constitutes a material uncertainty that may cast significant doubt about the company's ability to continue as a going concern such that it may be unable to realise its assets and discharge its liabilities in the normal course of business.

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
