About this data
- Costs are HM Prison and Probation Service's resource spending on public sector prisons in England and Wales, divided by the average number of prisoners (cost per prisoner) or by the number of places (cost per place). They include the costs of running prisons and a share of central and regional overheads, but not capital spending (such as building new prisons) or healthcare funded by the NHS.
- Financial years, shown by the year they end: 2025 is April 2024 to March 2025. Real-terms figures are adjusted for inflation using HM Treasury's GDP deflator (October 2026), in 2024/25 prices.
