Mounting overcrowding and persistent staffing shortages across Welsh prisons are placing both inmates and prison officers at increasing risk, according to a major parliamentary report that has raised fresh concerns about the state of the criminal justice system in Wales.
The cross-party Welsh Affairs Committee has warned that conditions within the Welsh prison estate are deteriorating, with overcrowded facilities, inexperienced staff and inadequate resources undermining rehabilitation efforts and prison safety standards. MPs described the situation as deeply concerning and urged the UK government to take urgent action to stabilise the prison and probation system.
The findings come amid broader national concerns over rising prison populations across the UK, increasing pressure on correctional facilities and ongoing debates surrounding prison reform, sentencing policy and devolved justice powers in Wales.
Welsh Prison Overcrowding Reaches Critical Levels
The parliamentary report highlighted severe overcrowding in several Welsh prisons, with inmates frequently being forced to share cells originally designed for single occupancy. MPs warned that such conditions are intensifying tensions inside prisons while negatively affecting mental health, rehabilitation opportunities and staff safety.
According to evidence presented to the committee, prisons including HMP Swansea, HMP Cardiff and HMP Berwyn in Wrexham are facing particularly acute operational pressures. Charlie Taylor, Chief Inspector of Prisons, told MPs that the strain on these institutions has become increasingly severe due to growing prisoner numbers and insufficient staffing capacity.
The report identified several factors contributing to overcrowding in Welsh prisons. These include longer custodial sentences over the past two decades, a higher rate of prisoner recalls in Wales and sustained pressures on funding and prison infrastructure.
MPs concluded that increasing prison capacity alone would not solve the problem. Instead, they argued that long-term improvements would require reducing dependence on custodial sentencing, improving rehabilitation services and ensuring prisoners are held closer to their home communities to maintain family connections and support networks.
Staffing Crisis Undermining Prison Safety
One of the central concerns raised by MPs was the ongoing staffing crisis within Welsh prisons. The report found that many institutions are struggling to recruit and retain experienced prison officers, leading to concerns about supervision, security and prisoner welfare.
At HMP Berwyn, for example, the committee found that 40% of band three prison officers holding supervisory responsibilities had been employed at the prison for less than a year as of January 2024. MPs warned that high turnover rates and lack of experience among frontline staff could significantly weaken prison management and increase operational risks.
The report stressed that prison staff require greater investment, improved working conditions and more competitive pay packages to address retention issues effectively. MPs also emphasised the importance of listening to staff concerns regarding workload pressures and workplace safety.
The committee stated that experienced officers play a vital role in maintaining order, preventing violence and supporting rehabilitation programmes within prisons. Without sufficient staffing levels, they warned, the system risks becoming increasingly unstable.
Concerns Over Women’s Prison Facilities in Wales
The report also renewed criticism over the absence of a women’s prison in Wales. Currently, female prisoners from Wales are often housed in prisons located in England, far from their families and support systems.
MPs expressed frustration over delays to a proposed residential women’s centre in Swansea, which was first announced by the Ministry of Justice in 2022. The facility had been described as a “ground-breaking” alternative to traditional custody for women offenders and was backed by £10 million in funding.
Originally expected to open in 2024, the centre has yet to materialise. MPs described the delays as “unacceptable” and criticised the lack of clarity surrounding how the facility would operate and who would qualify for admission.
The committee argued that the prolonged delay risks undermining efforts to provide more effective rehabilitation and support services for women involved in the criminal justice system.
Debate Over Justice Devolution Continues
The state of Welsh prisons has also reignited debate surrounding the potential devolution of justice powers from Westminster to Cardiff.
Plaid Cymru and previous Welsh governments have repeatedly called for justice and policing powers to be devolved, arguing that Wales should have greater control over its criminal justice policies and prison services. However, the UK government has consistently rejected those proposals.
While the committee stopped short of recommending full devolution, MPs acknowledged that the UK government must continue exploring options relating to probation and youth justice powers, in line with previous manifesto commitments.
The Welsh government reiterated its support for devolved justice powers following publication of the report. A spokesperson stated that only through devolution could Wales deliver fully integrated public services tailored to Welsh communities.
Rising Prison Deaths and Oversight Concerns
The report also highlighted concerns surrounding prison oversight mechanisms, particularly Independent Monitoring Boards (IMBs), which are responsible for scrutinising prison conditions and ensuring accountability.
MPs warned that resource shortages have at times prevented IMBs from operating effectively across Welsh prisons. They pointed specifically to the deaths of 17 men at HMP Parc in 2024 as evidence of the need for stronger oversight and sustainable resourcing.
The committee called for a review into why imprisonment rates in Wales remain consistently higher than those recorded in England and much of Western Europe. Experts have long questioned whether sentencing practices and social inequalities are contributing to disproportionately high incarceration rates.
UK Government Announces Prison Expansion Plans
In response to growing prison pressures nationwide, the UK government announced plans in December to create 14,000 additional prison places across England and Wales by 2031, describing it as the largest prison expansion programme since the Victorian era.
The Ministry of Justice defended its approach, stating that it is investing £7 billion to address what it described as a prison system already facing deep structural challenges.
A government spokesperson said the current devolution settlement allows Wales to benefit from the resources of a larger justice system while also supporting rehabilitation and community-focused initiatives.
Officials added that efforts remain focused on improving rehabilitation outcomes, reducing reoffending rates and strengthening coordination between prison services and local communities.
However, MPs warned that unless staffing shortages, overcrowding and rehabilitation failures are urgently addressed, Welsh prisons will continue facing serious safety risks that threaten both inmates and prison personnel alike.
