Depending on the work you're doing you might need to get planning permission or apply for building regulation approval, or both. If you go ahead without permission or approval, you might end up having to put things back to how they were.
You need building regulation approval to check that the work you're doing reaches certain safety and energy efficiency standards. You’ll probably need building regulation approval for:
- a new building
- an extension
- a loft conversion
- alterations to the structure of a building
- home improvements like a new boiler, radiators, bathroom, fuse box, electric, windows, doors, and roofing
