Question to the Home Office:

To ask the Secretary of State for the Home Department, what data his Department holds on the (a) longest and (b) average length of time people are held in Brook House immigration removal centre.

The Home Office publishes data on detention in the ‘Immigration System Statistics Quarterly Release’. Data on length of detention for people leaving detention is published in table Det_D03 of the ‘Detailed detention dataset’. The latest data relates to the end of September 2023. However this data is not broken down by last place of detention as this does not show where an individual spent their time in detention. In some cases, an individual may have spent a period of time detained elsewhere before being moved to their last place of detention.

Data on people leaving detention by last place of detention is published in table Det_04c of the ‘Detention summary tables’. However, this data is not broken down by length of detention, for the reason given above.

Information on future Home Office statistical release dates can be found in the ‘Research and statistics calendar’.
