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

“The directors have prepared projections that take into consideration the confirmed order book and multi-year sales pipeline. The forecasts assume that the company will continue to be profitable. At the date of approval of these financial statements, and based on the forecasts prepared, the predictions indicate that the company will remain within its existing facilities. The directors have therefore prepared the financial statements on a going concern basis.”
Auditor, going-concern and subsidiary information is drawn from the narrative of the latest annual accounts. About these numbers
