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

To ask the Secretary of State for Communities and Local Government, how many houses not compliant with Part M building regulations were built (a) in the last two years and (b) since 2010.

My Department does not hold the information requested.

Building control bodies (local authorities or private sector approved inspectors) assess new dwellings for compliance with the requirements of the Building Regulations, including Part M, at both plans stage and throughout the course of building work on site. If at any stage the building control body considers that a new dwelling would not be compliant on completion it will give the person carrying out the work advice and guidance on what is needed to make the dwelling compliant and a warning that a failure to comply might result in formal enforcement action. In almost all cases this is sufficient to achieve compliance. At the completion of work, if the work complies, the building control body will give a compliance certificate.
