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 1,473. The line on each bar marks the median.

From contract award notices on Contracts Finder (since 2016) and Find a Tender (since 2021), published by the Cabinet Office under the Open Government Licence v3.0. Values are as published by the buyer and usually cover the whole contract term; the total leaves out awards shared between several suppliers, where the published figure is a ceiling for all of them, placeholder values and single figures of £1 billion or more. Notices marked ‡ do not state a company number and were linked by an exact match on the registered name. Contracts below the publication thresholds and those of devolved buyers that publish elsewhere are not included.
