Permitted Development Rules for Roof Windows (Velux)
Generally permitted under Part 1, Class C of the GPDO. Roof windows are permitted provided they do not protrude more than 150mm beyond the plane of the roof slope. Side-facing windows at upper-floor level must be obscure glazed and non-opening below 1.7m from the floor.
Conditions
- 1Must not protrude more than 150mm beyond the existing roof plane
- 2Side-facing windows (on a wall or roof slope forming a side elevation) must be obscure glazed and non-opening below 1.7m from the floor
- 3The window must not result in the roof exceeding the existing ridge height
Size and Dimension Limits
- Protrusion: maximum 150mm beyond the roof plane
- No specific size limit for individual windows
When Permitted Development Does Not Apply
- In conservation areas, roof windows on the principal or highway-facing elevation may not be PD
- Listed buildings require listed building consent
- Multiple roof windows may cumulatively change the character of the roof, potentially requiring PP
What About Building Regulations?
Building regulations approval is likely required
Building Regulations may apply depending on the structural alteration to the roof. Covers structural integrity of the roof after cutting rafters, thermal performance (Part L), and fire safety (means of escape if the room is a habitable loft). A FENSA-registered installer or building control notification is needed for the glazing.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact North Warwickshire building control or use an approved inspector.
How to Apply in North Warwickshire
If you need planning permission for your roof windows (velux), you can apply through North Warwickshire's planning department or via the national Planning Portal.
If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from North Warwickshire. This provides proof that your project does not need planning permission, which can be helpful when selling your property.
What Happens If I Build Without Permission?
Low risk for standard roof windows within PD limits. Enforcement may occur if windows overlook neighbouring properties without being obscure glazed where required, or in conservation areas without consent.
