Do I need planning permission to upgrade to double glazed windows?

For houses, replacing windows with double glazing usually doesn’t require planning permission, provided the style and appearance are similar to the original. However, if you live in a flat/maisonette, listed building, or a conservation area, planning permission or listed building consent may be required, especially if the changes affect the external appearance.

You should contact your local planning authority or the Planning Guidance Service for more advice.
