I am an Electrical Inspector.
I to a degree don't care who does the work as long as the person in charge on the work site can demonstrate to me that the work has been done in a compliant manner and that that is backed up by test results and/or photo's of the installed work.
If they want to employ clowns, that is on their head, not mine, after all they are certifying their work.
All I do is make sure that no-one will get injured or killed by any dodgy work and that that work is of a certain minimum standard.
Just my 2c worth.
