Flats and maisonettes

Flats and maisonettes do not have permitted development rights.

So you'll need planning permission to replace or insert windows.

Houses that do not need planning permission

Houses have permitted development rights.

You may not need planning permission to replace windows and create new windows as long as:

  • the materials of the proposed windows are similar in appearance to the materials of the existing windows
  • any upper-floor side windows are:
    • obscure-glazed (not clear-glazed) and
    • do not open. Or the parts of the window that can be opened are more than 1.7 metres above internal floor level.

If your proposal does not meet these points, you'll need to get planning permission.

Houses that do need planning permission

Not all houses have permitted development rights. 

In some areas these may have been removed under an Article 4 Direction. Most Article 4 Direction areas are in the borough's conservation areas.

Check if your property is in an Article 4 Direction area and find out if you need planning permission.
