Report produced by Capacity Management Team.

The CNA and Operational Capacity figures are taken from the latest signed cell certificates held by CMT.

*The prison unlock figure may be lower than the 'Population', as the 'Population' includes prisoners on authorised absence.

** Useable Operational Capacity of the estate is the sum of all establishments’ operational capacity less 2000 places.

The report is compiled from data on the last working Friday in August 2017

Definitions of Accommodation Terms

Certified Normal Accommodation (CNA)

Certified Normal Accommodation (CNA), or uncrowded capacity, is the Prison Service’s own measure of accommodation.  CNA represents 
the good, decent standard of accommodation that the Service aspires to provide all prisoners.

Baseline CNA

Baseline CNA is the sum total of all certified accommodation in an establishment except, normally:
  •Cells in punishment or segregation units.
  •Healthcare cells or rooms in training prisons and YOIs that are not routinely used to accommodate long stay patients.

In-Use CNA

In-use CNA is baseline CNA less those places not available for immediate use, for example: damaged cells, cells affected by building works.

Operational Capacity

The operational capacity of a prison is the total number of prisoners that an establishment can hold taking into account control, security and the
 proper operation of the planned regime. It is determined by the Deputy Director of Custody on the basis of operational judgement and 
experience.

Useable Operational Capacity

Useable Operational Capacity of the estate is the sum of all establishments’ operational capacity less 2000 places. This is known as the 
operating margin and reflects the constraints imposed by the need to provide separate accommodation for different classes of prisoner i.e. by 
sex, age, security category, conviction status, single cell risk assessment and also due to geographical distribution.

Crowding

Where operational capacity of a prison is higher than the CNA it will be classed as having the potential to be 'crowded', which can mean 
prisoners share cells. Her Majesty’s Prison & Probation Service (HMPPS) collects the average number of prisoners held in crowded 
conditions (e.g. two prisoners held in a cell designed for one, or three prisoners held in a cell designed for two) and this is published in the 
supplementary tables at https://www.gov.uk/government/statistics/annual-national-offender-management-service-digest-2016-to-2017
