Erlestoke House was seriously damaged by a fire in 1950 and was then converted into a prison, with many additional buildings constructed. The site was first used by the Prison Commission in 1960 as a detention centre, became a young prisoners' centre in 1977, and a Category C adult male training prison in 1988. In 1998, it was reported that thieves had broken into Erlestoke Prison and stolen £3000 worth of gardening tools from a shed. Two years later, two inmates from Erlestoke used a makeshift ladder in a daylight jailbreak. The two escapees then stole a car from a nearby farm, but then crashed it, and were subsequently recaptured by the police. In December 2001, an inspection of Erlestoke by Her Majesty's Chief Inspector of Prisons found cells in the oldest part of the prison had damp walls and poor furniture. Cleanliness was also criticised, as was the ability of some staff "to adapt to new ideas on rehabilitation" at the prison. However, a year later, a report declared Erlestoke Prison one of the best in the country, with a Government official describing the inspection report as "astoundingly good". In March 2005, a report from the Independent Monitoring Board found that violent incidents at the prison had dramatically increased, to 1,400 annual incidents from its previous 800. In 2005, an employment tribunal awarded nearly £400,000 damages to a white prison officer of South African descent for "enduring years of racial abuse" in connection with black prisoners targeting him for his clearly identifiable accent. According to the officer, he had received little assistance from the prison's management. In August 2017, prison staff successfully ended a disturbance involving a few prisoners.
Current usage
Erlestoke Prison receives adult male prisoners from much of England and Wales, as well as from local prisons in South Wales and Bristol in particular. Accommodation at the prison comprises eight accommodation units, 3 Enhanced ; 3 Standard ; 1 Lifer and long-term prisoner unit and an Induction Unit. Most cells are single occupancy with integral sanitation. However, there are a small number of double, purpose-built cells on two of the accommodation units, and two three-bed cells on one other accommodation unit.
Attempted escapes
In September 2010, a low-risk prisoner, doing gardening work outside the prison, decided to escape with the prison's tractor that he was using at the time. Having travelled about ten miles, he was spotted by a former prison officer from Erlestoke who recognised the tractor and alerted the authorities, before tailing the tractor. Realising he was being pursued, the prisoner drove onto a golf course and was followed by several police vehicles; after abandoning the vehicle, he tried to flee on foot but was cornered by a police dog and taken back into custody.
Notable inmates
Alexander Blackman, often referred to as "Marine A", was held at HMP Erlestoke, having been charged with murdering an injured Taliban insurgent in the 2011 Helmand Province incident. He was found guilty in November 2013 and sentenced the following month. This sentence was reduced to manslaughter with diminished responsibility in March 2017.
