Outline of financial performance at Brook House and Tinsley House seems to show margins in excess of contractual limit
The security firm G4S appears to have been making more profit than its contract allows from the immigration removal centres (IRCs) it runs for the government, according to an internal document seen by the Guardian.
According to an outline of G4S’s financial performance at the two IRCs it ran in 2016, the company’s margin on its trading profit at Brook House was 20.7%. At Tinsley House, its other IRC, the margin was 41.5%, though that figure may be distorted by the fact that Tinsley House was closed for part of the year.
