Inquiry 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.

Each entry above links to a primary source — gov.uk written statement, consultation response document, or inspection report. The Index does not characterise government intent; it tracks what has been published.

How this page is built

Source and Response are verbatim from primary documents. The Evidence trail records published activity since — written statements, consultation outcomes, inspection findings, parliamentary references. The Index does not paraphrase or characterise intent; it tracks what has been published. Where the evidence is the absence of action (a missed deadline, a slipped timetable), that absence is documented from primary sources rather than inferred.

This recommendation's data is verified periodically against primary sources. The Index is monitored for staleness weekly.
