Background

HM Prison and Probation Service (HMPPS) is the executive agency of the Ministry of Justice (MoJ) responsible for managing the prison service in England and Wales. We last reported on the prison estate in 2020. We concluded that HMPPS was failing to meet its aims of providing a safe, secure and decent prison estate.

HMPPS was also facing a significant challenge to meet its commitment to deliver 13,400 additional prison places. We highlighted that MoJ and HMPPS needed to resist taking a reactive approach to capacity pressures and to instead work with HM Treasury produce a long-term strategy to deliver a prison estate fit for purpose.

Since then, MoJ has increased the scale of its prison expansion plans from 13,400 to 20,000 additional places by the mid-2020s in response to projected increases in demand. HMPPS is delivering the additional places through a portfolio of prison capacity programmes (prison expansion portfolio), which includes a mix of building new prisons, expanding and refurbishing existing prisons, and installing temporary accommodation.

HMPPS has delivered 6,518 additional places between 2020 and September 2024, 278 of which are from additional crowding at four private prisons. Despite this, the prison estate has been operating at close to full capacity since autumn 2022, with many prisons severely crowded.

If prisons reach full capacity, there would be significant impacts on the wider criminal justice system. For example, courts would not be able to try cases where suspects may be given prison sentences. MoJ and HMPPS have had to implement various emergency measures, such as releasing prisoners early, to ensure that the criminal justice system continues to function.

Scope of the report

This report examines:

  • MoJ’s and HMPPS’s progress in expanding and maintaining the prison estate
  • MoJ’s and HMPPS’s oversight and management of recent capacity pressures and the impact of measures it has used to alleviate pressures
  • future risks to the resilience of the prison estate

Conclusion

The current crisis in the prison estate is a consequence of previous governments’ failure to align criminal justice policies with funding for the prison estate, leading to reactive solutions which represent poor value for money. Policies such as introducing tougher sentences and increasing the number of police officers led to steep increases in expected demand for prison places. However, years of under-investment in maintaining the prison estate put MoJ and HMPPS in a weak position to respond to these increases.

HMPPS has therefore taken a reactive and expensive approach focused on building new places urgently at increased cost. Until there is greater coherence between the government’s wider policy agenda and funding for its prison estate, the current crisis position will not represent value for money.

HMPPS’s expansion plan was unrealistic and was not prioritised by the government, with resulting delays that have exacerbated the current crisis. MoJ’s central projection scenario shows demand for spaces exceeding capacity by 12,400 places by the end of 2027, even if current expansion projects are delivered to revised timelines.

We welcome MoJ’s commitment to a more sustainable approach to ensuring a resilient prison estate, although MoJ and HMPPS have yet to set out plans for closing the gap and considering the cost trade-offs involved. Emergency measures such as Operation Safeguard are expensive, while other measures may worsen prisoner rehabilitation or resettlement, which may lead to higher reoffending rates.

MoJ, HMPPS and wider government must ensure they learn lessons from the current capacity crisis and improve their handling of key risks and their focus on long-term resilience.
