Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Communities and Local Government, what estimate his Department has made of (a) how many and (b) what proportion of all completions of new homes sold in England and Wales have received an A grade for energy efficiency in their Energy Performance Certificate since 2010.

For the period Jan 2010 – 30 June 2015, 7,637 new build properties were registered as receiving an A rating. This represents approximately 1% of the new build properties lodged on the register during the same period. Because an A rating exceeds required Building Regulations standards there will be a limited proportion of new construction seeking to achieve this.

The percentage of B rated properties during the same period is 66% - properties achieving a B rating will be generally more energy efficient than the majority of the pre-2010 stock.
