- Audit opinion
- Unqualified (clean)
- Going concern
- Affirmed
“After making enquiries, the directors have a reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future, being a period of twelve months after the date on which the report and financial statements are signed. The company is relatively sheltered from the effects of global trade tensions and the ongoing wars in Ukraine and the Middle East. The business plan is robust enough to withstand significant adverse events. For these reasons, the directors continue to adopt the going concern basis in the financial statements.”
Significant events
- “There are no significant post balance sheet events.”
Auditor, going-concern and subsidiary information is drawn from the narrative of the latest annual accounts. About these numbers

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
