This report presents the first empirically grounded, holistic framework for understanding gambling-related harms
and recovery in Great Britain. It also introduces new measurement tools, representing the first GB-focused, co-
developed instruments designed to directly capture the full range and severity of gambling-related harms, both
for those who gamble and affected others. Drawing on lived experience, contemporary public-health thinking,
and methods used across health economics and policy evaluation, the work moves beyond narrow diagnostic
notions of “problem gambling” to capture how harms affect individuals, families and communities across
wellbeing, relationships and resources. Despite growing recognition of gambling as a public-health issue, no
previous programme has integrated harm, recovery, measurement and comparative impact within a single,
coherent framework. The programme is structured around four linked goals, described across four chapters
