Following a visit in July 2025, the HM Chief Inspector of Prisons noted some improvements since their last visit: "While the centre still resembled a prison, there had been good investment in the physical environment, entailing the closure of units on a rolling programme to allow for redecoration and refurbishment. The library had been significantly improved and now provided a relaxed and welcoming space for detainees. The progress made in tackling the ingress of illicit drugs was particularly notable and included use of new detection technology and better cooperation with the police.

However, despite some good work by the Home Office Detention Engagement Team, there was limited progress on the priority concern over support for the most vulnerable detainees. Too many detainees were still held for excessive periods and Rule 35 safeguards were not working effectively enough.

While the previous rise in violence had been arrested, there were still too many incidents, and data analysis remained weak. Routine handcuffing for external escorts persisted. The culture and service provided by health care had improved, but senior-level partnership working was still problematic and continued to affect service delivery.

While there was much that remained to be done by both Serco and the Home Office, there had been commendable progress since the critical inspection

After an unannounced visit to the centre between 5–22 August 2024, the HM Inspectorate Prisons reported: "Violence and self-harm had risen since the last inspection, and an influx of ex-prisoners had created instability. Detainees were being held for longer which increased the level of need and frustration. Almost half of those surveyed said they had mental health problems and 35% said they had felt suicidal while at the centre, yet health care provision was inadequate. Not enough was being done to tackle the ingress of illicit drugs.

Points to note: There had been a drive to improve the range of activities. Welfare work remained good, but it was understaffed, and in the past year at least 20 detainees had been released homeless. An active Home Office team had increased its contact and communication with detainees."

Furthermore in the report, concerns regarding detention lengths were raised: "In the absence of a detention time limit,10 people had been held for over a year and one man for over 500 days, an unacceptably long time to keep people in administrative detention."
