Notify is a voluntary scheme unique to London developed by the GLA and London councils. 23 London boroughs are loading information about their homeless households in temporary accommodation onto the notify system. This accounts for 72 per cent. of the households placed in temporary accommodation. The remaining 10 boroughs— Bromley, City of London, Enfield, Greenwich, Havering, Kingston upon Thames, Newham, Redbridge, Sutton and Wandsworth have formally signed up to participating in notify—and are providing sample information for testing and are using the system to view information about homeless households placed in temporary accommodation in their area by other London local authorities, or intend to load information once their boroughs’ new IT systems are fully operational.
