A release is defined as a release from prison where the prisoner has finished serving the custodial term of their sentence(s) and excludes:

  • civil non-criminal prisoners;
  • persons committed to custody for non-payment of a fine;
  • releases to hospital;
  • deported prisoners from HMPPS operated Immigration Removal Centres (IRCs); and
  • releases following recall after release on licence, except occasions:
    • where the offender has committed a new offence and is committed to custody for a new sentence and the subsequent release date falls after the sentence expiry date of the original sentence; or
    • where upon release the offender is subject to the licence condition of the new custodial sentence.
