Community Health and Wellbeing Workers (CHWWs) play a crucial role in bridging the gap between residents and the complex systems that shape their health, wellbeing, and daily lives. As part of a national shift toward community‑based, preventative care, CHWWs in Westminster work across health, social care, housing, finance, digital inclusion, and mental health to support residents with diverse and often interconnected needs.
This report provides the first systematic behavioural analysis of the CHWW programme, examining how and why CHWWs influence residents’ actions through specific Behaviour Change Techniques (BCTs) and mechanisms described by the COM‑B model. By analysing 23 CHWW‑written case studies, we identify the “active ingredients” that underpin the programme’s impact – most notably its emphasis on practical, relational, and holistic support. These insights offer valuable evidence to strengthen practice, inform evaluation, and guide the effective scaling of community‑based models of care.
