This report investigates the issues that influence the rate of heat pump installation across the social housing controlled by local councils in Scotland. The data was collected in January 2025 via semi-structured interviews with senior managerial staff directly responsible for their authority’s clean heat strategy, and triangulated with issue specific empirical, statistical, and public policy information. This research has found that the rate of heat pump installations across local authorities in Scotland is influenced by material, regulatory, and managerial factors.
