Magilligan Prison has been rated as one of the highest-performing prisons in the United Kingdom following a joint inspection that praised its “excellent” culture of respect and rehabilitation despite severe overcrowding and ageing facilities. The medium-to-low security jail near Limavady, which currently houses 500 men in buildings originally designed for 300, achieved top marks across all four “healthy prison” tests in a report published today by Criminal Justice Inspection Northern Ireland (CJI) and His Majesty’s Inspectorate of Prisons (HMIP).
UK-Leading Performance on Rehabilitation
Inspectors found that outcomes for prisoners had improved significantly since the last inspection in 2021, with the prison now rated “good” against the four key tests of safety, respect, purposeful activity, and preparation for release. According to detailed findings published by The Independent, prisoners spend eight to ten hours daily out of their cells—among the best rates inspectors have seen recently—and 72% of those surveyed said their experiences at Magilligan had made them less likely to reoffend.
The inspection team identified 19 examples of notable positive practice that other prisons could adopt, and found that 22 of the 30 recommendations made after the 2021 inspection had been achieved in full or in part. Educational provision was judged to be generally good quality, with 43% of qualifications achieved at Level 2, and inspectors praised innovative developments including the appointment of a dedicated learning and disability nurse to support neurodivergent prisoners and a formal data-sharing agreement with the South Eastern Health and Social Care Trust—the first electronic shared record of its kind in the UK.
However, the report also raised four priority and seven key concerns, including ongoing challenges with substance misuse. The inspection found that almost a quarter of prisoners reported developing a problem with drug misuse while at the prison, and Chief Inspector Jacqui Durkin noted that “inadequate funding and lengthy waiting lists for substance misuse and addiction services is contributing to the likelihood of prisoners resorting to illegitimate drug use to manage their addictions within the prison.”
“Outcomes for the men held at Magilligan Prison had improved since our last inspection in 2021 and were assessed as ‘good’ against each of the four healthy prison tests of safety, respect, purposeful activity and preparation for release,” said Jacqui Durkin, Chief Inspector of Criminal Justice in Northern Ireland, and Charlie Taylor, Chief Inspector of His Majesty’s Inspectorate of Prisons in England and Wales.
“The misuse of drugs by prisoners, including prescription medication, irrespective of who prescribed it or how it has got into the possession of a prisoner who should not be taking it, is a threat to the prison’s stability,” Ms Durkin added.
Minister Hails “Culture of Respect”
Justice Minister Naomi Long welcomed the findings, describing the result as “outstanding” given the pressures on the justice system.
“This is an outstanding result for Magilligan Prison and a testament to the dedication of every individual working there. To be recognised as one of the best prisons in the UK is a significant achievement, particularly when our entire justice system is operating under such immense pressure.”
“What stands out most in this report is the culture of respect. Our prisons are at their most effective when they focus on rehabilitation and hope. By providing a safe and supportive environment, Magilligan is not just holding people in custody; it is actively reducing the likelihood of reoffending and making our entire community safer. I want to thank the Governor Gary Milling and his staff for their commitment to excellence.”
Beverley Wall, Director General of the Northern Ireland Prison Service, said the report validated what management had long recognised about Magilligan’s high standards, but warned that maintaining these achievements would require urgent investment.
“I am extremely proud of the team at Magilligan. This inspection report validates what we have long recognised – that the leadership and staff at this establishment are delivering to an exceptionally high standard.”
“To be described as a model for the rest of the UK is a significant achievement. It reflects a prison that is professional, well‑run, and – most importantly – firmly focused on rehabilitation. While plans for the long‑term redevelopment of the site continue, this report underlines a fundamental truth: it is the people, not the infrastructure, who determine the success of a prison.”
“However, we must also be clear about the pressures facing our prison system. Maghaberry is operating under immense strain as the prisoner population grows, the complexity of those entering custody increases, and public finances tighten. At Magilligan, a site originally built for 300 people is now accommodating 500. Without sustained and strategic investment, maintaining the standards highlighted in this report will become increasingly challenging.”
Governor Gary Milling paid tribute to his staff and partner agencies, describing the prison as a “family”.
“This report is the culmination of many years hard work across the Prison. We like to think of Magilligan as a family, made up of many parts. Firstly, the leadership team and prison staff, but also the many partners agencies that work so hard to make this prison a success. While there are too many to name, each of them is a vital part in our work to support and challenge the men in our care, and to play our part in building a safer Northern Ireland.”
Infrastructure Deficits and System-Wide Pressures
While the inspection praised the prison’s rehabilitative culture, it highlighted the urgent need for capital investment to modernise the estate. The facility still relies on Second World War-era Nissen huts for some workshops, and the current population significantly exceeds the site’s original design capacity.
The positive findings at Magilligan stand in stark contrast to the pressures facing Northern Ireland’s wider prison estate. Maghaberry, the largest prison, currently holds 1,407 prisoners and has been forced to reopen disused cell blocks and increase cell-sharing to accommodate a population that has risen 50% since 2021. Across Northern Ireland, the total prison population reached 2,078 in March 2026, with nearly 40% of inmates held on remand.
The Department of Justice has confirmed that redevelopment plans for Magilligan remain a priority, with a new kitchen and café project currently underway and plans for a 60-cell wing at Halward House at an early business case stage. However, former Justice Minister Claire Sugden has warned that delays to the £108 million redevelopment are placing a “serious and avoidable strain” on the system.
Questions for Consideration
- If Magilligan can achieve UK-leading rehabilitation outcomes despite ageing infrastructure, what specific management practices and cultural elements could be transferred to Maghaberry to alleviate pressures there?
- How will the Prison Service address the drug misuse concerns raised in the report—where nearly 25% of prisoners developed problems while inside—without undermining the positive staff-prisoner relationships that underpin Magilligan’s success?
- With the prison population continuing to rise and capital projects delayed, can the “family” culture at Magilligan be sustained as the facility approaches 600 inmates, or will space constraints inevitably erode the standards inspectors have praised?
- Given that 72% of prisoners report being less likely to reoffend after their time at Magilligan, should sentencing policy prioritise placement at such facilities over remand at overcrowded establishments like Maghaberry?
