6 Response Accepted in Part

Review and reduce cell lock-in periods

Recommendation

The Home Office, in consultation with the contractor responsible for operating each immigration removal centre, must review the current lock-in regime and determine whether the period of time during which detained people are locked in their cells could be reduced. The Inquiry does not consider cost alone to be a sufficient justification for extensive lock-in periods.

Published Evidence Summary
The following publicly available evidence relates to this recommendation:
- In March 2024, the Home Office committed to implementing a maximum 9-hour overnight lock-in period, noting this was already being driven forward at Brook House (Government Response to the Brook House Inquiry, Home Office, March 2024).
- In November 2024, the Home Office published a new Detention Services Order on the Management and Security of Night State, setting a maximum 9-hour overnight lock-in period across the immigration removal centre estate, with version 2.0 superseding the December 2018 original (Detention Services Order: Management and Security of Night State, Home Office, November 2024).

In September 2024, Kate Eves told Channel 4 News she was "disappointed with what I see as an inadequate response by the former government to an important report." She noted the inquiry cost about £20 million over four years. Home Office lawyers had argued her "recommendations are not binding."
