Planning Permission for Window Replacements

Do You Need Planning Permission for New Windows?

In many cases, replacing windows in your home does not require planning permission. However, there are certain situations where a planning application is necessary, particularly in conservation areas, listed buildings, or when changing the style of the windows significantly.

When Planning Permission is Required

You may need planning permission if:

✔️ Your property is listed—any changes to windows must be approved.

✔️ You live in a conservation area or an Article 4 Direction zone, where restrictions apply to maintain the area's character.

✔️ You want to change the material or style of the windows significantly, such as switching from timber to uPVC.

✔️ Your property is in a flat or maisonette, where permitted development rights do not apply.

✔️ You plan to install bay windows, which are considered an extension rather than a replacement.

✔️ The new windows may impact overlooking or privacy concerns with neighbouring properties.
