Most asylum seekers in the UK are forced to 'sign on' at a nearby immigration reporting centre on a regular basis (daily, weekly or monthly). This involves finger-printing and re-activating their biometric ID cards. Many have to travel long distances and spend a significant amount of the already little money they are given on bus fares. There is no justification for all this hardship and humiliation other than the immigration authorities' wish to make life more miserable for refugees and migrants so that they give up and leave, as well as deterring others from coming here.

Many people have disappeared from these centres without warning. Most reporting centres are provided with so-called short-term holding facilities (STH), which consist of one or more secure cells. Most people detained in these 'holding rooms' are arrested without warrant in the adjacent reporting centre while signing on. A significant proportion are also brought in by snatch squads in prison vans, who are often based at these centres and operate in the surrounding area and carry out dawn raids.

Those detained are held in the STHs for lengthy periods of time, before being transferred to immigration detention centres around the country. The rooms often have no facilities to hold people overnight but this happens all the time. There are about 25 non-residential SHTs around the country, located at ports and airports as well as reporting centres, and 4 residential ones, which can hold people for up to 7 days.

The first time short-term detention facilities were exposed to independent scrutiny was in the summer of 2004, when an inspection programme for these centres was started by the Chief Inspector of Prisons. The first set of reports, which covered Communications House (London), Lunar House (Croydon), Electric House (Croydon) and Dallas Court (Manchester), found that "there is little external supervision or regular monitoring of these centres." In August 2005, Anne Owers said: "Though [short-term detention facilities] hold detainees only for short periods, they do so at a time of maximum anxiety and uncertainty, outside the public gaze."

The "systemic deficiencies" common to most, if not all, of these centres have become all too familiar: prolonged detention (due to over-crowdedness in 'normal' detention centres) despite the facilities' not being fit for holding people overnight; the use of force and segregation; lack of information and healthcare; inadequate facilities; untrained or inadequate staff (especially in dealing with children and self-harm); women and children being kept in the same room as single men and so forth.

All reporting centres in the UK are run on behalf of the UK Border Agency by private security company G4S, which also runs a number of privatised detention centres across the country and is the UKBA's main contractor for detainee escort services. G4S has been repeatedly criticised by the Chief Inspector of Prisons for "settled misery" in their detention centres, the lack of information provided to detainees about the availability of legal aid and such like.

London has two main immigration detention centres, Communicstions House and Beckett House.

Communications House, located just off Old Street roundabout, is open seven days a week and sees up to 500 people a day, mostly asylum seekers from across north and east London. Communications House is provided with a 'short-term holding facility', which holds on average five detainees a day, which consists of one secure room that has no facilities to hold people overnight. The holding room is normally staffed between 9am and 5:30pm by up to four G4S 'detainee custody officers' (DCOs), or longer if an escort is awaited to remove detainees. There are usually three DCOs and a supervisor on duty but they share duties with other G4S staff at other short-term detention facilities in the London area (Beckett House in south London and City Airport in east London). There are at least two G4S detainee escort vans based at Communications House, which has a secure vehicle compound. (For more information on Communications House, see here).

Beckett House, located near London Bridge, is the UKBA's immigration reporting centre and 'enforcement unit' base for south east London. It is open six days a week and sees every week hundreds of asylum seekers who are forced to sign on there. Beckett House is provided with a so-called short-term holding facility (STH), which consists of two adjacent secure cells behind the reporting centre. Most people detained in these 'holding rooms' are arrested in the reporting centre while signing on, but a significant proportion are brought in by snatch squads operating from the centre. Those detained are held in the STH for lengthy periods of time, before being transferred to immigration detention centres around the country, or to nearby police stations as there are 'no available beds' in detention centres. Detainees in the Beckett House STH are not offered a free private phone call or allowed to fax documents to their legal representatives. Furthermore, the reasons for their detention and other relevant information, such the possibility of applying for bail and sources of legal advice, are not provided or fully explained in a language they understand.
