The figures for the years marked † were read automatically from the scan and kept only where the statements add up (for example net assets equal total equity), but a reading error is still possible — check the original accounts at Companies House.

ENCON INSULATION LIMITED does not disclose its turnover in its latest accounts; the profit for the year is as stated in the accounts.

Positions are approximate. Figures come from each company's latest accounts; money and employee figures are compared only with companies that filed accounts in pounds for a period ending in the last two and a half years and are not dormant, so those groups are smaller than 27,659. The line on each bar marks the median.
