Several organisations and groups across the political spectrum have called for an economic stimulus of building retrofits, including Policy Exchange, McKinsey, Confederation of British Industry, Local Government Association, the Green Finance Institute and most recently, the Energy Efficiency Infrastructure Group.

This report adds to that growing list, but goes further and models a radical scenario where around 9 million UK homes receive whole-house retrofit measures over the remaining course of this parliament, saving around 15% of total domestic energy demand. This is not only necessary, but is also feasible. Through a bottom-up assessment of jobs and comprehensive policy proposals, this report adds the ​‘how’ to the growing calls for housing retrofit to be a key part of a green recovery.
