What’s the difference between planning permission and building regulations?

Planning permission and building regulations are different things, and many projects will need both.

• Planning permission controls what you can build — for example, the use of land and buildings, their appearance, access, and the effect on neighbours and the environment.
• Building regulations control how you build — setting safety and design standards covering structure, fire safety, insulation, energy use, and accessibility.

For many types of building work, both permissions are required.

• For internal alterations only, you may just need building regulations.
• If you’re unsure, check with us (for planning permission) and your local building control body (for example, Devon Building Control Partnership).

In short:

Planning = what you can build

Building regulations = how you build it safely
