Individuals released on temporary licence

Release on Temporary Licence (ROTL) is the mechanism under which offenders may be released into the community, generally towards the end of their sentences, for rehabilitative purposes. It can play an important role in public protection by allowing risk management plans for offenders to be tested in the community under strict conditions before they are released. It also provides a valuable means of helping offenders prepare for their resettlement in the community by, for example, finding work or rebuilding links with their families, which helps to reduce reoffending.

These figures show the number of individuals released on temporary licence at least once in the quarter. Some individuals may be released multiple times within the quarter or over multiple quarters. Therefore, it is not possible to sum multiple quarters together to find the number of releases on temporary licence over a longer period.
