CHAIN is a multi-agency database recording information about rough sleepers and the wider street population in London. The system, which is commissioned and funded by the Mayor of London and managed by St Mungo’s Broadway, represents the UK’s most detailed and comprehensive source of information about rough sleeping.
CHAIN is used to help workers share information to ensure that they act as quickly and effectively as possible to help those they encounter. Reports based on information held in CHAIN help decision-makers monitor the needs of rough sleepers in London.
