Prisons data

Public protection

To protect the public, prisons must hold prisoners securely. This not only prevents further offences being committed, but is an important foundation for the wider work of prisons in reforming offenders.

Visit prisons and probation statistics for data sources and more details.


Escapes from prison establishments and escorts

A prisoner escapes from prison if they unlawfully gain their liberty (for 15 minutes or more) by breaching the secure perimeter of a closed prison, or if during prison staff escort, overcome the control of escorting staff and leave the escort, the van or the building (hospital etc.). Those who escape for less than 15 minutes and commit an offence are also recorded as an escape.

Escapes are monitored to analyse the frequency across the estate and identify any trends nationally, also taking into consideration the management of risk to the public.

This total consists of escapes from establishments, HMPPS escorts, contractor escorts and includes escapes by Category A prisoners. For a further breakdown please see the HM Prison and Probation Service annual digest.

Absconds

An abscond is an escape that does not involve overcoming a physical security restraint such as that provided by a wall or fence, locks, bolts or bars, a secure vehicle, handcuffs or the direct supervision of staff.

Absconds are monitored to analyse the frequency across the open estate and identify any trends nationally also taking into consideration, the management of risk to the public. It is only possible to abscond from open prison conditions.

Temporary release failures

Release On Temporary Licence (ROTL) allows eligible prisoners to be temporarily released for precisely defined activities that cannot be provided in prisons.

A failure occurs when a prisoner fails to adhere to any condition written into the licence that permits their temporary release. Such conditions include the date and time by which the prisoner is required to return to the prison and may also place restrictions on where the prisoner may go and whom they may visit during the period of release.

Prisoners must be fully risk assessed before release is granted and must sign a temporary release licence setting out the applicable conditions and the duration of the licence.

Security audit

An internal audit that assesses, on a four point scale, the level to which effective security procedures are adhered to within each prison.

There is no structured frequency for how often the security audit takes place, with the exception of long term high security prison establishments which are audited annually. The data presented here shows the most recent assessment for each prison establishment.

The summary percentage is based on audits published internally by HMPPS. The annual prison performance ratings publication includes audits which had not been published when it was released and were therefore suppressed from the data tables. Including these suppressed scores, the overall percentage of prisons scoring a 3 or 4 is 85.8%

Values:

  • Rating 1: 7 prisons
  • Rating 2: 16 prisons
  • Rating 3: 57 prisons
  • Rating 4: 37 prisons
