Do I Need Planning Permission to Change my Windows?

If you’re looking to have replacement windows, install double glazing (or even triple glazing) then the chances are you might not need planning permission. This isn’t always the case, as like everything else, there are loads of exceptions to this rule. Planning permission is separate from Building Regulations Approval which sets the standard for health and safety.

If you’re looking to have replacement windows, install double glazing (or even triple glazing) then the chances are you might not need planning permission. This isn’t always the case, as like everything else, there are loads of exceptions to this rule. Planning permission is separate from Building Regulations Approval which sets the standard for health and safety.

If you’re doing basic maintenance or minor improvements to your standard or uPVC Windows such as a repair or repainting, then you definitely don’t need planning permission. If you’re adding in new windows, double glazing or not, that are of similar appearance to those used in the original construction of your house then you will not need planning permission. But if you are planning something larger such as a new bay window then this will be classed as an extension and will therefore require planning permission.

Unless you live within a conservation area or listed building it’s unlikely that you’ll need planning permission for the windows as the alterations are minimal and are unlikely to affect your neighbours. If you do need planning permission though this needs to be obtained before the changes are implemented. Good news is that your double glazing installer should be able to advise you of your need for permission and seek it should you need it.

When adding double glazed windows to the upper floor side elevation of your house then they must be obscure- glazed and either non opening or more than 1.7 metres above the floor level to not require planning permission.

Replacement windows

When looking at installing roof or skylights as a general rule they don’t need planning permission unless they fall into these categories:

  • They protrude more than 150mm beyond the plane of the roof slope
  • They are higher than the highest part of the roof
  • If they are in the side elevation roof slope and less than 1.7 meters above the floor level

Of course if you live in a listed building you’ll need planning permission for the addition of any form of double glazed windows or uPVC Windows. Listed buildings are properties which are deemed to have historical or architectural significance and anything built before 1700 is considered listed, and a vast majority of those built between 1700 and 1840 are also listed. A small number of newer buildings are also listed but there are no specific criteria which makes them this way. These buildings are protected by law and you must obtain planning permission before you install double glazing, and whether internal or external listened consent must be given for any significant works, or works which alters the look of the building.

If you are a leaseholder, than you must get the permission from your landlord or management company to make any significant changes or work to the property.

Before any home improvement takes places – including the addition of double glazed windows – most homeowners will need to acquire planning permission. Planning permission is granted by the council and is a way for the area to oversee the way that your town or city develops. When considering the application for planning permission landscaping is taken into account alongside the external appearance of your building, road access and impact on neighbours and the general environment.
