Building regulation fees


Approval with full plans

There are two ways to pay:

  • pay the total fees upfront
  • pay the submission fee when you apply and we will then invoice you for the inspection charge, once your first inspection is booked. We will not send you a completion certificate to prove works have been signed off until you pay the inspection charge.
