I am glad to hear about the gas fitters license,we have always used reputable ones for our generator hookups ect, but i know what you mean they are out there,the other thing is that on forced hot water systems the actual final hook up to "House or city water system must be completed by a licensed plumber and the electrical hookup by a licensed electrician.,we in the trade have always looked for more oversight in these areas,glad to see the states are finaly getting with the program ect.
Have a great day,& feel free to contact me anytime should you have any questions ect. or need a licensed electrician ect.
