This, so much this. Part of being a qualified professional is that you keep up to date with the latest standards. This clown clearly hasn't, and as such his advice means squat. It would have to be pretty damn dodgy for them to report it, ie. totally unsafe that is actually putting someone in danger. Even then most would tell you about it, and give you a quote to fix it. Some would quietly just fix it without even telling you. The problem is that it is difficult to explain to most people that just because a task is simple to do, it is the knowledge of WHY it is done that way that is the most important.
