Harmondsworth currently has a capacity of 615, which makes it the largest detention centre in Europe. It holds only men and the security in several of the wings is comparable to a Category B (high security) prison. Harmondsworth is run by a private security company called GEO, under contract to the UK Border Agency.
The last inspection by Her Majesty’s Inspectorate of Prisons took place in 2010. The report noted improvements, but nevertheless showed areas of deep concern.
