Rules for New Windows in a Conservation Area

Conservation areas are designated by local authorities to protect and preserve the historic and architectural character of certain areas. They are usually comprised of older buildings and structures that have significant cultural and historical value.


Typically these areas will feature the use of traditional windows, which are important to maintaining the area's overall character. Therefore, there are often specific rules and regulations in place regarding the installation, maintenance, and replacement of windows in conservation areas.


In this blog, we will take an in-depth look into some of these rules and what they mean for homeowners.


  • Obtaining Planning Permission

One of the most important rules to follow when installing or replacing windows in a conservation area is to obtain planning permission from your local council. This is to ensure that any changes are in keeping with the overall character of the area and will not have a negative impact on its historic and architectural significance. Failure to obtain planning permission can result in fines and legal action, so it is very important to seek advice from your local planning department before proceeding with any changes.

  • Materials

When it comes to materials, conservation areas often require that homeowners use traditional materials, such as timber or metal, or a combination of both for windows in the area. This is to ensure that any new windows are in keeping with the character and appearance of the surrounding buildings and structures. uPVC or plastic frames are very rarely permitted, as they can look out of place and detract from the overall aesthetic of the area.

  • Design

The design of windows is also important when it comes to conservation areas. Traditional designs such as sash windows or casement windows are often required, more modern styles may not be permitted, certainly on the facade of the building. It's important to ensure that any new windows are sympathetic to the existing buildings in the area and do not look out of place.

  • Glazing

Conservation areas often require that any new windows use traditional glazing techniques, such as single-glazing or double-glazing. This is to maintain the appearance of the windows and ensure that they are in keeping with the overall character of the area. Double-glazing or other modern glazing techniques may be permitted in certain circumstances and often only at certain thicknesses, but it's important to seek advice from your local authority before making any changes.

  • Maintenance

Finally, it's important to remember that maintaining traditional windows is key to preserving their appearance and functionality. Homeowners should regularly inspect and maintain their windows to ensure that they are in good condition. This may include regular cleaning, repainting, or even minor repairs to the frame or glazing, failure to do so may also result in voiding of your warranty.


In conclusion, homeowners in conservation areas must follow specific rules and regulations when it comes to installing, maintaining, and replacing windows. These rules are in place to ensure that any changes are sympathetic to the character and appearance of the surrounding area.


By following these rules and seeking advice from your local authority, homeowners can ensure that their windows are in keeping with the conservation area and contribute to the overall preservation of the area's cultural and historic significance.
