Audit opinion

Unqualified (clean)

Going concern

Affirmed

“The directors, making due and careful enquiry, have prepared forecasts and have a reasonable expectation that the group has adequate resources to continue to operational existence for at least 12 months from the balance sheet signing date. Thus the directors continue to adopt the going concern basis of accounting in preparing the financial statements.”

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
