The London homelessness social impact bond project, was launched in November 2012. It was designed to bring in additional finance to support innovative services aimed at improving outcomes for a cohort of 830 persistent rough sleepers.

This is the first interim report from the qualitative evaluation. An economic and impact evaluation is being undertaken internally at the Department for Communities and Local Government. The qualitative and impact strands of the evaluation will be brought together in a synthesis report in 2016.

To date, social impact bond providers have valued the chance to provide a flexible service that focuses on sustained outcomes. In turn, service user experiences have been overwhelming positive.
