What About Building Regulations?
Building regulations approval is not usually required
Building Regulations do not normally apply to solar panel installation on an existing roof, provided the roof structure can support the additional load. If structural alterations to the roof are needed, Building Regulations may apply. Electrical work must comply with Part P and should be carried out by an MCS-certified installer to qualify for Smart Export Guarantee (SEG) payments.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Trafford building control or use an approved inspector.
How to Apply in Trafford
If you need planning permission for your solar panels, you can apply through Trafford'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 Trafford. 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-mounted panels on non-listed, non-designated-area properties. In conservation areas or on listed buildings, enforcement can require removal of panels installed without consent.
