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

To ask the Secretary of State for Housing, Communities and Local Government, what assessment he has made of the proportionality of the requirement for planning permission to install double glazing.

My Department has not undertaken such an assessment, as in most cases the replacement of windows of similar appearance can be undertaken without the need for a planning application.

However, there may be some local exceptions, and other consents such as listed building consent may be required.
