The following table shows the number of prisoners who, according to the Prison Service IT system, were potentially eligible for the home detention curfew (HDC) scheme and who opted out in each year since the scheme began on
|Number who opted out|
Data are not held as to why prisoners have opted out of being considered for HDC. However, among the most likely reasons are that the prisoner cannot provide details of a release address or will consider that that he/she is highly unlikely to pass the risk assessment and so does not bother to apply.
Information on the number of people who opt out of the end of custody licence scheme is not recorded.
These figures have been drawn from administrative IT systems, which, as with any large scale recording system, are subject to possible errors with data entry and processing.
