BACO Prisoner Support Service

Wing representatives support residents in making an application to BACO, they work with the BACO volunteer in a face to face situation.  Fortunately, BACO has been developing a partnership with Milton Keynes College (the education provider) to receive applications remotely.  This has been invaluable during 2020/21 with the onset of the restrictions due to the Coronavirus pandemic.  BACO has been able to support the residents throughout this time.


Contributory grants are made towards the cost of

  • Educational courses
  • Educational qualifications
  • Course books & materials
  • Art materials
  • Musical instruments
  • Essential clothing & shoes
  • Radios
  • Birth certificates for ID

Wing Socials

The five therapeutic communities hold two social events during the year. BACO members are invited to put their names forward to receive backing from the men to attend the social event on the wings. They attend subject to complying with the prison’s security procedure.


An annual quiz between members and prisoners takes place with a BACO cup awarded to the winning team – it rarely leaves the prison!
