If you're building something new, or making changes to an existing building, you may need building regulation approval.
This makes sure the work meets health and safety, energy and accessibility standards, and gives you the certificates of compliance you need when you want to sell your home or building.
It's illegal to not tell us about your building work. You might have to correct the work or pay a fine if you do not tell us about it.
Alternatively you can download the Building Regulation form and return the completed form and fee to:
Building Control Service, PO Box 102, Civic Centre, Sunderland, SR2 7DN
