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.

Audit opinion

Unqualified (clean)

Going concern

Affirmed

“The Group and its subsidiaries are expected to operate within its budgets set by the board in order to meet its future expansion plan, whilst ensuring the financial covenants set by lenders are met. Furthermore, in the unlikely event of financial distress, management has strong levers to control discretionary investment which makes up the majority of the group's investment profile. Therefore, it can be asserted that the group and its subsidiaries are a going concern at the balance sheet date.”
