I have my red expansion vessel of my unvented heating system replaced by a gas engineer. He showed his GasSafe card and I assumed all was well, only afterwards upon finding him on the GasSafe register I see that he is qualified for 'vented cylinders' but not 'unvented cylinders'
Is the expansion vessel classed as part of the unvented cylinder system or is the wording exact as in its just the cylinder itself that he cannot work on? I other words, should he have replaced it with his qualifications.
