What the project is for

The Accelerated Houseblocks Programme supports our 20,000 additional prison places commitment; its scope is to deliver around 2,400 places.

Departmental delivery commentary

Compared to financial year 24/25-Q4, the NISTA Delivery Confidence Assessment remains at Amber. This is primarily due to inflation and increasing cost maturity resulting in increasing cost estimates and other market risks.

Schedule

Compared to financial year 24/25-Q4 the programme’s end date changed from 10/07/28 to 01/11/30. This is primarily due to scope increases within the project resulting in more time required to achieve overall programme completion.

Cost

Exempt under Section 43 - Commercial interests

Benefits

This programme currently reports no monetised benefits. Due to the projected increasing prison population, this programme focuses 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.
