Gas information sheet 33: Gas installation notification

View as PDF

Overview

The intent of this technical information sheet is a guide for Gasfitters to help identify whether the gas installation they are completing is a Standard or Complex gas installation. Once this has been determined the Gasfitter will be able to notify the appropriate authority; the Victorian Building Authority (VBA) or Energy Safe Victoria (ESV).

Standard gas installation

Standard gas installations require the lodgement of a Compliance Certificate (CC) to the Victorian Building Authority (VBA) within five days of completing the installation, pursuant to Section 221ZH of the Building Act 1993.

Complex gas installation

Complex gas installations require the Gasfitter to obtain acceptance by Energy Safe Victoria (ESV) prior to commissioning the gas installation. You must submit a Gas Application before beginning work and at the completion of works a statement of compliance (Schedule 11 of the Gas Safety Regulations) must be received by ESV.

Refer to the attached tables to identify your installation type and to which authority (VBA/ESV) you lodge your application.

Definition

Storeys above the ground

The number of storeys above ground is a deciding factor as to whether the installation is a Standard installation or a Complex installation. Be aware the ground floor of any building is the 1st storey of that building and all subsequent floors above ground are measured from the ground floor.

Class  2 – Standard

A building containing two or more sole-occupancy units each being a separate dwelling.

This class can be Standard or Complex; read carefully limitations, criteria and notice requirements in the right hand column.

Standard

Building of 5 storeys or fewer above the ground is considered a standard installation.

Building of 6 storeys or more above the ground where the residential premise is occupied or has been previously occupied. Standard gas installation work is limited to inside the premise, (i.e. downstream of the occupancy gas isolation point in the premise).  E.g. the changeover of a gas appliance or the extension of the existing gas fitting line inside the premise to a new gas appliance.

Class  2 – Complex

A building containing two or more sole-occupancy units each being a separate dwelling.

This class can be Standard or Complex; read carefully limitations, criteria and notice requirements in the right hand column.

Complex

Building of 6 storeys or more above the ground where the residential premise is not occupied and has never been previously occupied. However, irrespective of whether the building is occupied or has been previously occupied, if a gasfitting line is being installed from the building gas riser into the premise, the gas installation becomes a complex gas installation.
