The research is being led by Energy Saving Trust in consortium with Taylor McKenzie and Elmhurst Energy.

The research aims to (1) identify the range of archetypes of the UK housing stock that are complex-to-decarbonise (CTD), (2) help householders and industry understand the economic costs and trade-offs associated with different decarbonisation approaches across the different CTD archetypes, and (3) propose the best practice approaches to making low carbon heating viable and affordable for CTD householders.

The research involved ~450 in-person retrofit assessments of homes deemed likely to be complex, and subsequent desk-based evaluation of measure mixes to determine suitability of installation, costs to install and potential savings. Findings are expected to be published in Spring/Summer 2026.
