Prison population and capacity
Blantyre House · June 2019
No population was published for Blantyre House in June 2019.
Read from the Ministry of Justice’s June 2019 bulletin, in the vintage we archived on 11 August 2026. The count was taken on 28 June 2019.
Blantyre House was published with no accommodation in use in June 2019, so there is no crowding figure to calculate. A percentage of zero certified places is not a number, and we would rather show nothing than invent one.

What the bulletin publishes, and what it means
- Baseline CNA122
- The sum total of all certified accommodation in an establishment, except normally cells in punishment or segregation units and healthcare cells not used for long-stay patients.
- In-use CNA0
- Baseline CNA less those places not available for immediate use — damaged cells, cells affected by building works.
- Operational capacity0
- The total number of prisoners an establishment can hold without serious risk to good order, security and the proper running of the planned regime. Determined by Prison Group Directors on the basis of operational judgement and experience.
- Populationnot published
- The number of people held. The publisher notes that the prison unlock figure may be lower, as the population includes prisoners on authorised absence.
The publisher’s own definitions, quoted from the bulletin. We divide the population by in-use CNA rather than by operational capacity: operational capacity is what an establishment can be pushed to hold, in-use CNA is what it was certified to hold decently, and dividing by the larger of the two flatters every prison in the estate.
