Visitors We are the largest provider of immigration removal centre management and operations, and secure escorting services (in-country and overseas) for the Home Office, caring for over 13,000 detainees. We are specialists in the delivery of custodial services. A strategic partner to the Home Office, we support them in their work to effectively manage the immigration detention estate and flows of detainees in and out of the country, whilst upholding the welfare of those in our care at all times. We provide secure escorting services throughout the UK and overseas. This involves securely escorting detainees around the immigration estate and back to their home countries of origin on scheduled and charter flights. We also manage holding rooms and short term holding facilities at multiple air/sea ports and reporting centres throughout the UK, working closely with Border Force.
