Evidence for impact is our new platform that makes the growing evidence base on homelessness easy to explore and understand. Interrogate the evidence, work through key questions, and act on what works to prevent homelessness. Bring trusted research directly to your decision-making, today.

Our Evidence Tools for homelessness put evidence at people's fingertips, making the available evidence easier to use and highlighting where more and better evidence is needed. Our tools show what the evidence says about homelessness interventions and help you make smarter decisions about how to best serve those experiencing homelessness in the future.

Learn more about our programme of trials and evaluations: testing ways to reduce homelessness and end rough sleeping, and mapping the homelessness and rough sleeping system.
