Prisons delivered a damning report on the conditions, in which the prison was told to improve or close. In March 2004, a further report from the Chief inspector stated that Wormwood Scrubs had greatly improved after making fundamental changes. Three quarters of inmates at the prison had said that staff treated them with respect, which was better than the national average. However, the report also stated that inmates spent too much time in their cells, and that only 36 per cent of eligible inmates were involved in education or work. In November 2008, another report from the Chief Inspector stated that conditions at Wormwood Scrubs had deteriorated since the last inspection. Heightened prison gang activity had been detected, and 20 per cent of prisoners had failed drugs tests. The prison cell blocks are Grade II listed, with the gatehouse given the higher Grade II* rating. Major structural changes to the prison's management took place in 2013. In 2014, another report by the Inspectorate of Prisons was critical of the prison, describing it as "filthy". The inspectors also stated that there had been a failure to put into place recommendations by the Prisons and Probation Ombudsman to deal with suicide and self-harm. The Chief Executive of the Howard League for Penal Reform, a charitable body, said "I have never seen a public service deteriorate so rapidly and so profoundly." In 2017, the prison was reportedly overcrowded and some areas were strewn with litter and infested with rats and cockroaches. At the time of the inspection, there were 1,258 prisoners. Some were locked in their cells for 23 hours a day. The prison was reportedly dangerous for staff and inmates, and officers were concerned for their safety. There were 40 to 50 violent incidents a month. Chief Inspector Peter Clarke described “an extremely concerning picture” including, "intractable failings" continuing since earlier inspections from 2014. In 2018, a prisoner was stabbed to death and three other prisoners were charged with his murder. On August 30, 2018, prisoner Winston Augustine committed suicide in the segregation unit after spending two days locked in a showerless cell with no food and without the tramadol prescribed for kidney stones that caused him pain. He was suffering from ketoacidosis due to starvation. A 2021 inquest subsequently identified the prison's failure to provide food and medication as contributing factors to the death; the facility's head of safer custody told
