We questioned HMPPS on what it saw as the biggest risks in the expansion programme. HMPPS told us that it is challenging reprocuring the service as it is changing and as the number of tagged people is increasing. It explained that it has been managing this in different ways, such as getting its expansion projects into live service ahead of the re- procurement, ensuring there are dedicated resources in place and introducing a “change freeze” to ensure there will be no major changes as it switches over to its new suppliers.47
