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

Margins divide P&L lines by turnover. Gearing is liabilities over total assets. Current ratio is current assets over creditors falling due within one year. Interest cover is operating profit over absolute finance costs. Sector-distribution context coming next.
