London short term holding facilities (STHF)

AI-generated report summary This report details the operations of London's Short-Term Holding Facilities (STHFs) from February 2024 to January 2025. While positive aspects include safe environments, respectful staff interactions, and improved medical support, significant concerns persist. These include extended detention times in unsuitable conditions, particularly for children, lack of privacy, and inadequate access to medication and reliable translation services. The IMB makes recommendations to the Minister, UK Border Force/Home Office, and Mitie Care & Custody to address these systemic issues, many of which are recurring from previous reports.

Positive findings

AI-generated summary
The Board observed that all holding rooms generally provide a safe environment for detainees, with DCOs regularly checking on vulnerable people and children. Inductions were mostly of a high standard, and searches were conducted sensitively. Good practice was often seen in managing unaccompanied children and families. The Board welcomed a reduction in the number of people detained for over eight hours, as well as plans for the refurbishment of all holding rooms starting in summer 2025. Border Force officers and DCOs were frequently observed treating detainees with respect and providing genuine care. The appointment of an Aeromed medic has improved medical assistance, and the Board noted many removals proceeded smoothly due to a compassionate escort approach.

Key concerns

19 items
Safety Repeated The Board has observed that some children had extended waits in the CWA. There are no facilities for children in this area, nor is the environment comparable to that in the family room.
Safety The child-sized benches with an adult-height table in the family room at London City Airport pose a risk of injury to detained people.
Safety The safety of people being removed may be compromised if there are insufficient escorts to control a difficult situation, particularly in complex cases.
Staffing Repeated The Board recommends that more officers be deployed at peak times to avoid unnecessarily extended periods of detention in the controlled waiting areas and the holding rooms.
Regime/Time Out of Cell Those held in the CWAs have no, or very limited, privacy, other than in Terminal 4, where a thin partition affords privacy. The CWA at Terminal 2 appears to be too small for the number of people regularly held there.
Regime/Time Out of Cell Repeated Not all detainees are offered a translator on arrival, and delays or unavailability of certain languages in The Big Word translation service cause problems for inductions and communication.
Regime/Time Out of Cell Repeated Holding rooms are not equipped for stays over 24 hours, but detainees frequently have long stays, often overnight, without sufficient mattresses and blankets, or access to natural light and fresh air.
Estate/Conditions Repeated The temperature in the holding rooms, both at London Heathrow and London City Airport, is sometimes too cold or too hot, and Detention Custody Officers (DCOs) are unable to control it directly.
Estate/Conditions Repeated Toilet seats in holding rooms at Heathrow have still not been installed in Terminal 5, and showers in Terminals 2 and 3 were frequently out of order.
Regime/Time Out of Cell Repeated In previous reports, we have recommended that DCOs are reminded to engage regularly with detained people during their long periods of detention because they may not remember everything they have been told during their induction.
Regime/Time Out of Cell Repeated Lack of internet access still causes problems with translation devices and prevents passengers who struggle to communicate verbally to interact with their environment. This is a particular problem in Terminal 2. The promised internet trial started during the year but has now stalled.
Complaints/Property The quality and tone of responses to questions raised in our monitoring reports are variable and we are concerned that agencies may be missing opportunities to learn from complaints and improve practices.
Healthcare Repeated People detained at London City Airport and Eaton House still do not have access to their own prescribed or over-the-counter medication.
Resettlement/Release Repeated Asylum seekers (adults and children) who have been bailed sometimes face long waits for Clearsprings (the company contracted to provide transport and accommodation for asylum seekers) to pick them up. Unavailability of accommodation or transport is often given as the cause.
Other The provided lists of legal advice providers are often unhelpful, with detainees having little prospect of accessing timely legal advice.
Food/Catering The water fountains have not been in use since the beginning of the Covid-19 pandemic and have yet to be restored.
Food/Catering Lack of choice in microwaveable meals, particularly for halal food, and infrequent availability of fresh fruit. Source wording under review
Equality/Diversity Non-independent wheelchair users could be denied access to holding rooms if not accompanied by a carer, as C&C staff are not trained to lift and carry disabled individuals.
Complaints/Property Response times are variable, sometimes exceeding 20 days. The Board would like to see responses within 15 days.

The holding rooms are not equipped for stays over 24 hours and the Board would like to a significant reduction in the 3.5% of detained people experiencing these long stays.

Repeated Source text verified

Response
The number of stays of over 24 hours is still an issue of concern, although the Board is pleased to note the reduction in the number of stays over 24 hours.

Source text verified

Recorded status:

Topic: Safety

Recommendation 9

Addressee: Home Office

The temperature problems in the holding rooms, both at London Heathrow and London City Airport, need to be resolved. The Board would like to see DCOs be given some form of control, either by being able to directly adjust the temperature or by asking someone to adjust the temperature at their request. The temperature problem in London City Airport was also raised in last year's report.

Repeated Source text verified

Response
This is still an issue at times. The refurbishment may support an improvement in this situation.

Recommendation 12

We repeat the recommendation that the detention contractor should ensure that DCOs use The Big Word interpretation service for inducting non-English-speaking passengers and that they should not assume that passengers with a limited grasp of English really understand what they are being told.

This has continued to be an issue this year.

Delays and unavailability of certain languages in The Big Word translation service need to be addressed.

Delays are still experienced at times.

Recommendation 14

Addressee: Other — other

In previous reports, we have recommended that DCOs should be reminded to engage regularly with detained people during their long periods of detention, because they do not remember everything they have been told during their induction. This year, again, we observed people who would have benefited from a reminder of what is available to them in the holding rooms. We, again, make this recommendation.

This has been an issue on some occasions.

Recommendation 15

Addressee: Other — other

The mattresses in the holding rooms are very thin. We would like Mitie Care & Custody to continue their search for thicker mattresses.
