Ranby was converted in the early 1970s from its original use as a World War II British Army camp. Some of the army billet accommodation remains at the prison today. Some purpose built accommodation was added to the complex in 1980s, and two further wings were opened in February 1996. Two more wings of the prison were opened in Summer 1998, and a further wing was opened in March 2008, with capacity for an extra 60 prisoners. The prison has been criticized for its conditions: in 2002, a study by the Prison Reform Trust found that prisoners were not always offered privacy from their cell mates while using the toilets, which they labelled as "degrading". Two years later, the Independent Monitoring Board stated that the Prison was overcrowded and had problems with safety standards. The Board reported that vulnerable prisoners' safety in particular was being put at risk, especially at night, while also praising the prison for its work in education, physical education and chaplaincy. In 2005 the Board called for a new wing to replace the oldest part of the prison. A 2007 inspection report from Her Majesty's Chief Inspector of Prisons raised concerns about security and drug use at Ranby Prison. The report also criticised the prison's anti-bullying programmes, accommodation and resettlement work. A further report in 2012 noted strengths is staff-prisoner relations, resettlement, vocational training and work environment for prisoners, but concerns about that a quarter of prisoners were locked in their cells, the availability of debt and financial advice services, a number of unscreened toilets, insufficient efforts to reduce violence and self-harm, and high levels of drug and alcohol availability. They were also concerned about the health care provision.
