Prison governors warned against unsafe cell doubling as overcrowding crisis deepens

Prison governors across England and Wales are being warned to stop putting two inmates into cells designed for one person, according to a leaked letter from the Prison Governors' Association that has surfaced amid a deepening overcrowding crisis. The six-page document, titled Operational Capacity Guidance, reminds prison leadership that they are legally bound under the Prisons Act 1952 and Prison Rules to ensure every cell meets basic health and safety standards—adequate size, lighting, heating, ventilation, and working fixtures—before any inmate is confined there.

Yet the reality on the ground tells a different story. Prison staff speaking to the BBC describe a system under acute strain, where the pressure to maintain operational capacity has begun to override safety protocols. One governor acknowledged the bind plainly: two prisoners in cells built for one is "not ideal," but the pressure to keep the prison functioning leaves little choice. Some cells have broken heating or plumbing systems, the governor noted, and inmates "shouldn't really be in there to be honest." Another staff member pointed to the crumbling infrastructure in older facilities and warned that cramming people into cells with non-functioning toilets or sinks will only worsen conditions.

The numbers explain the desperation. The adult male prison estate in England and Wales is operating at 98.5% capacity, with prison sources reporting just over 1,200 spaces remaining across a total population of around 83,400 inmates. Some facilities—large Victorian jails—hold more than 1,000 prisoners each. The pressure is relentless and the margin for error is nearly gone. Staff have told the BBC that rules are being stretched or broken to accommodate additional inmates, and there is growing concern that the government is pushing prison management to accept more people than they can reasonably house. One prison worker summed up the staffing crisis bluntly: there are not enough people to monitor the extra prisoners, not enough infrastructure to house them, and those making the decisions need to either follow the law or justify why they are forcing governors to take on more people than the system can safely hold.

The decision on how many inmates a prison can hold does not rest with the governor. That authority belongs to the Prison Group Director, who sets operational capacity by calculating the total number of inmates a facility can hold while maintaining control and security. Some staff regard the leaked guidance as a warning shot—a signal that governors are being put in an impossible position by their superiors, who are the ones actually determining these dangerous capacity levels.

John Podmore, a former prison governor, called the situation "fundamentally unfair." Governors are being forced to manage a crisis they did not create, he said. The public may have little sympathy for prisoners, but that does not change the reality: putting a second bed in a cell and calling it capacity does not make it sensible or safe. Podmore also pointed to a larger structural problem: the system is quietly returning thousands of people to prison through recall mechanisms. If ministers want more space, he argued, they should examine why the revolving door is spinning faster rather than simply squeezing two people into cells built for one.

The government has announced an early release scheme beginning in October to create breathing room. Starting October 1, approximately 700 offenders serving sentences of up to 19 months will be released after completing a third of their sentence. On October 13, a second group of 650 prisoners serving sentences between 19 months and two years and five months will follow. In total, around 4,500 offenders will be released early over a ten-month period. The Ministry of Justice framed this as part of a broader effort to address a capacity crisis it inherited—one where only 500 additional places were created over 14 years. The government says it is delivering 14,000 new places, with nearly 3,300 already completed, converting existing spaces into cells, securing land for future prisons, and removing foreign national offenders faster.

But some senior prison staff believe the early release scheme will provide only short-term relief. They worry that once the immediate pressure eases, the pressure to push capacity to the maximum—or beyond—will return. The leaked guidance and the warnings it contains suggest that governors are already operating in a legal and ethical gray zone, and without structural change, that zone will only grow darker.
