Each state of Australia has its own governing agency that oversees gas safety. Victoria’s governing agency is Energy Safety Victoria (VIC). They set legal standards related to the use of gas appliances indoors, outdoors, and in semi-enclosed spaces such as alfresco areas. These legal standards must be adhered to.

      It is vital that you understand if your Alfresco area is classed as enclosed or outdoors.

    Is My Alfresco Area Enclosed?


    Your alfresco is NOT considered to be enclosed, and would therefore be classified as an outdoor area, only where;

    • The area has walls on all sides but at least one permanent opening at ground level and no overhead cover.
    • The area has a partial enclosure that includes an overhead cover and no more than two walls
    • The area is partially enclosed including an overhead cover and three or more walls with at least 25% of the total wall area completely open AND at least 30% of the remaining wall area is open and unrestricted.

    If your alfresco area is more enclosed than the above diagrams, then it is classified as indoors. One significant change which now is in place for Home owners , Builders,Landscapers and Plumbers is the gas barbecue installations that requires that an appliance approved for commercial use, installed in residential premises, be fitted with an interlock to the gas supply so that the installed extraction system must be in operation before gas will flow to the appliance.

    Energy Safety VICTORIA’s requirements for indoor alfresco areas are as follows:

    • BBQ must have flame failure devices fitted to every burner and be licensed for indoor use with a commercial certification (Please be aware that not all BBQs with a flame failure device are also licensed for indoor use)
    • BBQ must have a commercial grade exhaust hood that moves a minimum of 2000 cubic metres of air per hour and This requires the appliance to have an interlock installed, so that the extraction fan is operating before gas will flow to the appliance.
    • BBQ must be installed on a non-combustible surface.
