Mitie Care and Custody
Simpson was a senior operational manager for Mitie Care and Custody at Campsfield House IRC from April 2012. Campsfield was gutted by a major fire in October 2013, which spread due to an absence of sprinklers, despite recommendations from the fire brigade.

He took over the role of centre manager from Paul Morrison until July 2014 and says he "supported the mobilisation of the Heathrow contract", a reference to Mitie's new contract to run Harmondsworth IRC and Colnbrook IRC.
In July 2014 Simpson became a business manager for the First Bus Doncaster networks.
