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

- Going concern
- Affirmed
“In auditing the financial statements, we have concluded that the directors' use of the going concern basis of accounting in the preparation of the financial statements is appropriate. Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.”
Significant events
- “Impact of trading resulting from the Ukraine conflict and the recent Iranian conflict.”
- “Supply-chain pressures, inflation in raw-material and logistics costs, and exchange-rate fluctuations between sterling, the euro, and the US dollar all influenced trading conditions during the period.”
Auditor, going-concern and subsidiary information is drawn from the narrative of the latest annual accounts. About these numbers
