What are conservation area rules for windows?

Replacing sash windows is pretty straightforward. Unfortunately, when you live in a conservation area, that makes the matter far more complicated. You wouldn’t think windows would cause too much trouble for homeowners, but homes built within a conservation area need special permission to be replaced or repaired. So, what are the rules for windows in a conservation area?

Permission is needed for all sash windows

Regardless of whether you want to upgrade or repair old windows, they are likely to require special planning permission from the local authorities or conservation board. It’s a huge challenge because double glazing and UPVC windows are typically banned in conservation areas. The reason is down to the fact that conservation is there to protect the look of the original building. So, every little change (to the exterior) must be sympathetic to the original design.

It means replacing old sash windows becomes tougher, although not impossible.

Is planning permission necessary for all conservation areas?

In simple terms: yes, you are typically going to need permission to make any alterations or changes to windows in conservation areas. Typically, local authorities want to see more like-for-like repairs than new window installations. That doesn’t mean to say you can’t repair old sash windows on your property; you just have to do so in a manner that’s in line with current guidelines.

Understanding the guidelines

Planning applications are necessary to install new sash windows. Remember, if the new windows ‘destroy’ or are considered a ‘threat’ to the character of the building, your application may be rejected. It is, however, possible for you to install UPVC windows even in a conservation area. Of course, the number one rule to this is that the new windows cannot be significantly different from the original design.

Why are there restrictions in conservation areas?

Conservation areas were created to protect and preserve historical buildings. It can be a great thing as period properties (that hold lots of historical value and beautiful designs) are preserved for the next generation. Of course, there are drawbacks to conservation, including issues replacing old sash windows.

It’s important to seek advice before installing new windows or making any changes to the building. You should also understand the local restrictions and laws when it comes to conservation. Typically, if your new windows are in line with the old sash windows, your application shouldn’t run into difficulty (not much, anyway).

Know where you stand before you make any alterations

Buying a listed or protected building can be wonderful because it’s a part of history. Some of the original features can be gorgeous and priceless in many ways. Of course, there are issues with making changes, especially to the exterior of the property. You’ll need special planning permission to alter the windows of a listed building or one that’s within a conservation area. Fortunately, with a little know-how, you can install new sash windows or make repairs with little effort.
