Housing First is an evidence-based approach which supports people with multiple complex needs and entrenched homelessness to live in their own homes. Funded by Bristol City Council in 2018, Golden Key initiated a Housing First pilot to establish the feasibility of delivering high fidelity Housing First in the local Bristol context of extreme affordable housing shortages. This has since expanded over three phases to house and support 28 people of the 40 recruited who have the highest and most entrenched multiple complex needs (all data contained in this report up to December 2020).The Golden Key Local Evaluation Team at UWE developed an evaluation framework collaboratively with Golden Key and designed evaluation activity aligned with this framework. The evaluation research activity included two rounds of semi-structured stakeholder interviews, (May 2018 and Dec 2020-Jan 2021), quantitative analysis of clients’ demographic, engagement, and outcome assessment data (taken at the end of 2020), and a client journey mapping exercise. The journey mapping was unfortunately limited due to the pandemic which has severely restricted the evaluation’s ability to understand the client’s experience
