Building regulation fees
Application fees will be increasing from 1 April 2025. Applications received after 5pm on Monday 31 March 2025, will be charged at the new rates.
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.
