But his boss is not the person you have engaged to be the person who certifies the work.
Who?
Then you need to understand the legal requirements (BTW - you should know that there has never been a prosecution for notification contraventions, and the chances of there ever being one are on a par with HMQ indulging Donald Trump's alleged predilection for a certain yellow liquid during a state visit).
Notifiable work may be done by anyone who can do it in compliance with Part P.
- If it is done by an electrician registered to self-certify compliance with the Building Regulations then he just does it and tells the LABC after the event.
- If it is done by someone who is not such an electrician then either
- that person applies for Building Regulations approval before they start work, or
- that person engages someone who is registered as a 3rd-party certifier before they start work.
