I know this has been done to death but, I have just reached the stage where the electrician is ready to test and the builder about to start agitating for his final payment.
What is the actual mechanism of certification? *He does it on line* from the builder. I'll sign it off when I have the gas and electrical certificates from building control.
The safest would appear to be, wait for the BC to say the job is finished or....?
