To ask the Secretary of State for Communities and Local Government what estimates her Department has made of the number of houses which have been built to the carbon emission standards set out at (a) Level 3, (b) Level 4 and (c) Level 6 of the Code for Sustainable Homes; and if she will make a statement. (184240)

The Building Research Establishment has informed the Department that there are currently 395 registered developments that are building to the code, covering around 30,000 homes. Four of these are now formally going through the design stage assessment. Of those four going through the design stage, two are aiming for Code level 3 and two are aiming for Code level 4. BRE has also received the first post-construction assessment, for a development which was designed to Code level 4.

Other homes may have been built to the carbon emission standards set out in the Code for Sustainable Homes but may not have been built to meet the other sustainability requirements of the code and may not therefore have been assessed against the code.
