Conservation areas are designated areas with unique historic or architectural features that require special attention and preservation. If you live in a conservation area and are considering replacing your windows, it's important to understand the regulations and guidelines that govern these areas. In this guide, Jewel Windows will explore the regulations for window replacements in conservation areas and provide guidance on how to navigate them.
Why Conservation Areas Have Specific Rules for Window Replacements?
Conservation areas are characterized by their historical or architectural significance, and the preservation of their unique character is of the utmost importance. Windows play a crucial role in defining a building's appearance and character, and any changes to it can significantly impact the overall aesthetic and heritage value of the area.

Regulations for Window Replacements in Conservation Areas
In most cases, planning permission is required for any alterations or improvements in a conservation area when changing or replacing existing windows. The application process involves submitting a form with supporting documents. It is essential to contact your Local Planning Authority for advice on permissible window types and the need for a planning application. The Local Planning Authority may also require specifications and designs that restrict material and style choices.
Choosing Replacement Windows for Conservation Areas
When choosing replacement windows for a conservation area, traditional materials such as timber are recommended to meet the regulations set by the Local Authority. Single glazed timber windows can offer a classic look but you will also need to think about the long term benefits that come with double glazed windows in terms of energy efficiency and better insulation. Other materials, such as uPVC, may require additional planning permission and should be in keeping with the area's character. However, at Jewel Windows, we can make the process easier for you.

Considerations for Window Replacements
While our sash window replacements can be a great option for conservation areas, there are also some considerations that you should be aware of.
• Sizing and Design: The size and design of the new window should be in line with the existing one. Planning permission may be required if the new window is not the same or substantially similar to the existing one in terms of opening mechanism, number, orientation, colour of panes, dimensions, and frame or astragal bar colour.
• Rear and Side Elevations: In most cases, windows on the rear or side elevations of a building in a conservation area are not restricted. However, it is still advisable to consult with the Local Planning Authority to ensure compliance.
• Principal and Road Facing Elevations: Windows on the principal elevation or side elevations that face a road may require prior approval if the proposed window is not similar to the existing one.
• Listed Buildings: Listed Buildings require Listed Building Consent and must adhere to specific requirements. The Local Planning Authority will provide guidance on the necessary steps and considerations for replacing windows in listed buildings.
