What the project is for

The Category D Programme supports our 20,000 additional prison places commitment; it will provide additional permanent places across the Category D open prison estate

Departmental delivery commentary

Compared to financial year 24/25-Q4, the NISTA Delivery Confidence Assessment rating at 25/26-Q4 remains at Red. This is primarily due to issues arising from the administration of a key supplier.

Schedule

Compared to financial year 24/25-Q4, the project's end date at 25/26-Q4 changed from 20/09/29 to 20/03/31. This is primarily due to the programme’s key supplier entering administration and the resulting delays on delivery.

Cost

Exempt under Section 43 - Commercial interests

Benefits

This programme currently reports no monetised benefits. Due to the projected increasing prisons population, this programme focusses on increasing capacity and there are no monetised benefits to be claimed. The programme's other benefits are defined in the current baseline as: construction benefits and outcomes (capacity, modern methods of construction and sustainability); to enable an improvement in prisoner rehabilitation outcomes; and, during its construction, deliver local community benefits.
