Part P notifiable work checker
Answer the questions to see if the job is notifiable.
Common questions
What does notifiable mean?
Notifiable work has to be reported to building control. Either a registered competent person does the job and notifies it for you, or you tell building control before the work starts and pay for them to inspect it. Either way the homeowner should get a building regulations compliance certificate.
Does non-notifiable work still have to meet the rules?
Yes. All electrical work in a home in England and Wales must still meet Part P and be designed, installed, inspected and tested to BS 7671. It just doesn't need reporting to building control. An electrician should still give you a certificate for it.
Why are England and Wales different?
England reduced the list of notifiable work in April 2013. Wales kept a wider list, so work in kitchens and outdoors, and some other jobs, are still notifiable there.
What happens if notifiable work wasn't notified?
It can cause problems when you sell or remortgage, and building control can ask for the work to be put right. You can contact your local building control about a regularisation application for work that was done without approval.
