Material uncertainty over going concern
The Directors have a reasonable expectation that the Company has adequate resources to continue in operational existence and to meet its liabilities as they fall due for at least 12 months from the date of signing of these financial statements and believe that it is appropriate to prepare the financial statements on the going concern basis. This creates inherent uncertainty around the intentions of the owners of the Group for the duration of the going concern review period, with regards to the ongoing business and as a result, a material uncertainty is considered to exist that may cast significant doubt on the Group and Company's ability to continue as a going concern.

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
