HM Prison Berwyn
HM Prison Berwyn is a £250 million Category C adult male prison in Wrexham County Borough, Wales. It is the largest prison in the UK, opened in 2017, and is operated by His Majesty's Prison Service.
Name
The prison's name was announced by then-Governor Russ Trent on 17 February 2016. The name Berwyn comes from the elements of Middle Welsh barr and gwyn. A spokesperson for the National Offender Management Service said that the prison had been named after the Welsh mountain range. The original shortlist of six names was: Bridgeway, Marcher, Cerrig Tân, Dee Vale, Whittlesham and Y Berwyn. These names were suggested by local schools, communities and historical societies.Structure
The prison is split into three houses, the first, Bala opening in February 2017 and the other two, Alwen and Ceiriog in the autumn. Each section can hold different communities including one for armed forces veterans.Operation
It was designed to house 2100 men and to be the cheapest to run Category C prison in the country, with a projected cost of £14,000 per inmate. However as of 2019, it is still incomplete, only 60% full and costs £36,000 per prisoner each year.Enforced cell sharing
The prison was planned to be at 75% capacity by the end of 2017 but in June 2018, 16 months after opening, the prison was still only half full. It has been suggested that this is due to the contentious design of the prison, which requires a high proportion of prisoners to share cells, to cut costs. Prior to the design of Berwyn, the Prison Service worked on the basis that one person to a cell was the norm.In 2023, Liz Saville Roberts, Plaid Cymru MP, raised concerns about the prison, stating it had almost surpassed the 2,000 cell capacity for the first time since operating. She also claimed many cells had been trashed and not repaired, putting them out of usage.
