i am right in saying that to work on gas for no gain you only have to be competent but to work for gain you must be registered.
However what you have added is an interpretation of competence, if so it adds another dimension that suggested competence means registered?? seems to contradict the previous statement, however if you prove me wrong ill gladly admit it, i would just like to see where it says what you have posted as i cannot find it
BTW I dont agree with the interpretation, but im happy to abide by it if its proven. You may ask why i dont agree with it, its becaus ei have a friend who worked at BG all his life, helped set up acops, heped set up ACS, was an inspector for year, he is now retired, if he wants to service his boiler, by your understanding he is not competent, i would disagree
