Recommendation 4

We recommend that BEIS review its cost projections on energy efficiency and includes the cost of low carbon heating. The Department should consult the building and retrofit sector to ensure that its top-down modelling reflects real-world costs. It should also set out the proportion of efficiency improvements it expects to be paid for from the public purse, and how many homes it considers out of scope for energy efficiency improvements under its definition of “cost effective, practical and affordable”. There is a danger that these homes will be left behind, and this could impact on wellbeing and create permanent blight. The Government should explain in response to this report what its strategy is for those homes that will not achieve its energy efficiency aspirations.
