If you're unsure if you need building regulations approval please see:
Before you start work
It is illegal to start work without notifying us first. You might have to correct the work or pay a fine if you do not tell us about it.
You will also need a certificate of compliance if you want to sell your home.
If you don’t obtain a completion certificate it may void the insurance policy on the property. It is strongly advised you check this with your insurer.
Apply for building regulations approval
Apply for a building notice
For minor work on single family houses such as garage conversions, toilet installations and small extensions.
You don't need to submit any plans but you must be confident that the work being done will comply with building regulations. You risk having to fix any issues after we have inspected if it is not correct.
Apply for full plans submission
Submit detailed plans of the work you are doing. It is cheaper and gives you the most protection.
I've already started work
If you started work without getting building regulations approval you must now apply (there will be a charge).
We'll check whether it meets the building regulations standards and issue you a certificate if it has. If it doesn't meet standards you might have to correct the work or pay a fine.
Please note: You cannot get approval for any work completed before 12 November 1985.
