At the last minute before my BSS examination, the examiner realised that I am a live-aboard, residential boater. "Is a bubble tester installed?" he asked, "If not, I can't do the examination as I'm not Gas Safe certified." Needless to say, I don't have a bubble tester, he couldn't do the examination and the chances of finding a Gas Safe registered BSS examiner in my area is very high on the 'no chance' scale. Bottom line? If I want to get my BSS test done, I need to find a Gas Safe installer to fit me a bubble tester. Does anyone know of a Gas Safe registered installer in the Sheffield area?
