The government will conduct a detailed review of converting sections of the female prison estate into facilities for male inmates as ministers seek to relieve mounting pressure on the male prison system, which is operating at near-maximum capacity.
Prisons Minister Catherine McKinnell will investigate the practical feasibility of such conversions over the coming months, following warnings from prison governors and sector experts that the proposal would present substantial operational and logistical difficulties.
Earlier in the summer, Andy Burnham indicated the government's intention to examine releasing more women from custody as a mechanism to create additional capacity and prevent the early release of higher-risk male offenders. However, the detailed strategy announced this week prioritised deporting foreign nationals and curtailing indefinite imprisonment for public protection sentences rather than focusing on female prisoner numbers.
After objections from victims' representatives and families, Burnham modified the early-release framework. He announced that offenders convicted of all categories of manslaughter, rape, child sexual abuse and grooming would be excluded from the scheme. Approximately 4,500 prisoners are scheduled for early release in 10 tranches beginning in October, representing 1,500 fewer individuals than the original proposal.
The male prison system faces acute capacity constraints. As of 1 September 2026, approximately 1,500 free spaces remained in male prisons, down from 3,040 at the start of June, with the estate operating at 98% capacity. By contrast, the Justice Ministry reports 82,508 male prisoners and 3,350 female prisoners in the system.
Former Justice Secretary David Gauke and other experts have cautioned that operating prisons at such high occupancy levels carries substantial risk. Officials have advised ministers that achieving a genuine reduction in the female prisoner population would require extended planning horizons and cannot be treated as a short-term solution.
What do campaigners say about the conversion plan?
Penal reform organisations have expressed concern that converting female facilities would address symptoms rather than underlying causes. Andrea Coomber, chief executive of the Howard League, warned that the approach fails to resolve systemic overcrowding.
"[It] does nothing to fix a prison system that is fundamentally too full – it just moves the crisis from one part of the estate to another,"she said.
"Without real investment in women's centres and community alternatives, women risk being sacrificed to the scramble for more beds for men."
Pia Sinha, chief executive of the Prison Reform Trust, cautioned that any reduction in the female prison estate must be coupled with expanded community support.
"Any decision about the future of the women's estate must recognise this reality,"she said.
"Rather than viewing a women's prison as a solution to overcrowding in the men's estate, the government's priority should be implementing the Women's Justice Board's recommendations and building the community support that can deliver better outcomes for women and safely reduce the number of women in custody in the first place."
What is the government's position on female prisoners?
Victims Minister Alex Davies-Jones stated that the government maintains that the majority of women in custody, many of whom are mothers with dependent children, should not be imprisoned and could be appropriately managed through community-based women's centres. However, she rejected a uniform approach to conversion, telling LBC that some women must remain in custody and that decisions would be made on a case-by-case basis.
"There are some women who absolutely should be in prison, and they will remain there. But where there is a case to answer that we can re-purpose the female estate, because we know the prison capacity problem is in our male estate, 98% at capacity in the male estate, then we will look to re-purpose to see what we can do to free up capacity and move the estates around."
Women currently represent less than 5% of the total prison population in Britain and are held across 12 dedicated facilities. Government sources indicated that prisoners most likely to be released would be those in mother and baby units, where male prisoners cannot be accommodated.
What changes are being made to early release?
The government's early-release scheme has undergone significant modifications since its initial announcement. From 13 October 2026, governors will release a second tranche of 650 prisoners under the early-release scheme, continuing the phased approach. Additionally, the Sentencing Act 2026 release changes were delayed from 2 September to 1 October 2026, with the Prison Reform Trust noting that the timetable shift resulted from a policy review conducted this month.
The release-point modifications affect prisoners serving standard determinate sentences, altering release eligibility from 40% or half of sentence to one-third for some offenders, and from two-thirds to half for others. From 2 September 2026, Home Detention Curfew became unavailable as a routine option for adults, further restricting release pathways.
What broader investment is being made?
Beyond the early-release framework, the government is pursuing infrastructure solutions to address capacity shortfalls. The administration has committed £110 million to convert existing prison infrastructure into additional cells, drawn from existing budgets as part of a broader £7 billion commitment to the prison system. This investment forms part of a multi-year strategy to expand capacity while managing the immediate crisis.
