6 Response Accepted in Part Self-assessed

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:
The Home Office stated that a maximum 9-hour overnight lock-in period has been implemented across the immigration removal estate, alongside a drive to improve the range of activities available to detainees (Govt response, 19 March 2024). A parliamentary question in January 2025 indicated this recommendation was "completed and closed as of October 2024" (Angela Eagle, Written PQ 23170, 15 January 2025). HM Inspectorate of Prisons noted in September 2025 an upgraded library and relaxed spaces at Brook House, which could support increased activity (HM Inspectorate of Prisons, 3 September 2025).

Brook House Inquiry Chair Other

Inquiry Chair Kate Eves described government response as "inadequate" and called for a "reset" with the new government. Warned abuse "becomes a question of when, not if" it happens again.

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."
