Gas Appliance Service Certificate
The Australian Gas Appliance Service Certificate is issued by a licensed gasfitter following the servicing and maintenance of gas appliances such as boilers, space heaters, and cookers. It records the work performed on each appliance, parts replaced, operating pressure, and CO readings, along with a tightness test and ventilation check. Appliance manufacturers recommend annual servicing to maintain safety, efficiency, and warranty validity, and this certificate provides the formal documented evidence of that work.
