It is believed its premises are not suitable for a modern prison anymore.
4. Holme House Prison: 1,211 inmates
With a large 1,211 people capacity, the prison is located in Stockton-on-Tees. The prison is designed with both single and shared accommodation cells but it has been subject to multiple riots since its opening in 1992.

But life behind bars wasn’t always that promising at Liverpool prison.
Multiple inspections showed the lack of leadership in the prison’s staff, leading to multiple new appointments at the management level. Poor care conditions at Liverpool prison led to diseases and even death for some of its convicts.
