Audit opinion

Unqualified (clean)

Going concern

Affirmed

“The Directors have prepared the financial statements on the going concern basis as they do not intend to liquidate the group or the Company or to cease their operations, and as they have concluded that the group and the Company's financial position means that this is realistic. They have also concluded that there are no material uncertainties that could have cast significant doubt over their ability to continue as a going concern for at least a year from the date of approval of the financial statements ("the going concern period").”

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.
