When considering double glazing for your home, it’s important to understand whether planning permission is required. In the UK, the need for planning permission depends on several factors, including the type of property and its location. This article provides a comprehensive guide to help you determine if you need planning permission for double glazing.
General Rule
For most properties, installing double glazed windows does not require planning permission. Double glazing is generally considered a “permitted development,” meaning you can proceed without formal permission as long as the new windows are similar in appearance to those being replaced.
Exceptions to the General Rule
- Listed Buildings: If your home is a listed building, you will need to obtain Listed Building Consent before making any changes to the windows. Listed buildings are protected due to their historical or architectural significance, and any alterations must preserve their character.
- Conservation Areas: Homes located in conservation areas are subject to stricter regulations to maintain the area’s character and appearance. You may need planning permission if your double glazing installation alters the appearance of the windows significantly.
- Flats and Maisonettes: If you live in a flat or maisonette, you may need planning permission for double glazing. This is because changes to windows can affect the overall appearance and structure of the building, which may require formal approval.
- Article 4 Directions: Some areas are subject to Article 4 Directions, which restrict permitted development rights. If your property is in such an area, you may need planning permission for double glazing.
Building Regulations
Regardless of whether planning permission is required, double glazing installations must comply with UK Building Regulations. These regulations ensure that the windows meet safety, thermal performance, and ventilation standards. A certified installer can self-certify their work, or you can apply for Building Regulations approval from your local authority.
Choosing a Certified Installer
To ensure compliance with Building Regulations, it’s advisable to choose an installer certified by a Competent Person Scheme, such as FENSA or CERTASS. These installers can self-certify their work, saving you the hassle of seeking local authority approval.
Conclusion
In most cases, installing double glazed windows in the UK does not require planning permission. However, exceptions apply to listed buildings, conservation areas, flats, maisonettes, and properties subject to Article 4 Directions. Regardless of planning permission, compliance with Building Regulations is essential. Choosing a certified installer can help ensure that your double glazing installation meets all necessary standards and regulations.
