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

To ask the Secretary of State for Housing, Communities and Local Government, what steps the Government is taking to support energy efficiency in domestic dwellings through the replacement of single glazed windows with double or triple glazing; and in what circumstances is planning permission required for such replacements.

Forthcoming changes to the energy performance model underpinning Energy Performance Certificates will ensure that fabric improvements made by consumers, such as installing double or triple glazing, are suitably recognised and rewarded by the model.

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.
