I will give you my honest opinion here. Avoid the B.Gas ticket. It`s becoming less and less acceptable. The forefront qualification at one time is fast becoming 2nd class. Even behind the ridiculous ICORR qualification for some employers. NACE is the way to go. I am B.Gas level 2 myself so I have nothing against B.Gas. I have been knocked back many times in recent months because I don`t have NACE. Your call though.
