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
“The Directors believe that it is appropriate for the financial statements to be prepared on a going concern basis, given the financial support being provided by the parent of the Group, Colt Group Holdings Limited, to enable the Company to meet its financial liabilities as they fall due and continue its operational existence for the next 13 months from the date of approval of the Company's financial statements.”

Significant events
