If you’re considering installing a roof window in your home, one of the first questions you’ll probably ask is: Do roof windows need planning permission?
The good news is that in many cases, the answer is no. Most roof window installations fall under Permitted Development rights, meaning planning permission is not usually required. However, there are some important exceptions to be aware of.
When Planning Permission Is Not Required
Most homeowners can install roof windows without planning permission provided that:
- The roof window does not project more than 150mm from the roof slope.
- It does not extend higher than the highest part of the roof.
- Side-facing windows are obscure glazed if required.
- The property is not subject to additional planning restrictions.
This means that many Velux roof windows can be installed quickly and easily without the need for a formal planning application.
When Planning Permission May Be Required
There are situations where planning permission could be necessary, including:
Conservation Areas
Properties located in conservation areas may have stricter planning controls. Additional permissions may be required depending on the location and appearance of the roof window.
Listed Buildings
If your property is listed, you will typically need Listed Building Consent before making alterations, including the installation of roof windows.
Significant Roof Alterations
If your project involves major changes to the roof structure, dormers, or extensions, planning permission may be required.
What About Building Regulations?
Even if planning permission is not needed, roof window installations must still comply with Building Regulations.
These regulations help ensure that the installation meets standards relating to:
- Structural safety
- Energy efficiency
- Fire safety
- Ventilation
- Means of escape where applicable
A professional roof window installer can ensure your project complies with all relevant regulations.
Do Velux Windows Need Planning Permission?
