Question to the Department for Levelling Up, Housing & Communities:

To ask the Secretary of State for Communities and Local Government, what the average standard assessment procedure energy rating score of new build homes was in each quarter for which figures are available since April 2010.

The table below lists the average energy rating scores for new dwellings in England over time:

^{Note: ‘New dwellings’ will include conversions and change of use, as well as new build.}

The average scores will fluctuate by quarter, as they will be skewed by the profile of the particular housing stock being developed in that quarter, for example, the relative proportion of new build vs. conversions; the relative sizes of the dwellings; relative structures; differences in construction materials; types of design and the individual heating/lighting/windows in each dwelling. Notwithstanding those quarterly fluctuations, there is clear long-term trend of improving energy efficiency.
