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

- Unqualified (clean)
- 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.”
Significant events
- “The R&D team relocated to a much larger site in Leeds central which enabled the increasing headcount to continue our commitment to technological development.”
- “Lead times have stabilised in certain areas, though stock levels remain slightly above normal to mitigate potential global supply disruption.”
- “The final phase of the Hoddesdon HQ refurbishment was completed, increasing capacity, improving workflow, and reducing energy consumption.”
- “The London office was realocated from Bevis Marks to Finsbury Circus, providing a slightly larger space at a similar outlay and consolidating training and hotdesking into one space.”
- “Turnover increased by 13% compared with the previous year, supported by a rise in order intake from £20 million to £21 million, representing 5% growth.”
Auditor, going-concern and subsidiary information is drawn from the narrative of the latest annual accounts. About these numbers
