Certificates of compliance - gas fitting

Gas fitters must provide customers with a gas certificate of compliance after completing gas installation work in any location, including homes, rental and commercial premises, caravans, and boats.

Gas fitters must provide certificates of compliance for:

  • installing, replacing, removing/decommissioning or repairing gas pipework
  • installing new, pre-owned or replacement gas appliances
  • relocating existing gas appliances
  • installing new or replacement gas appliance flue pipes
  • converting gas appliances from natural gas to LPG, or vice-versa
    • if a Type A gas appliance is being converted to an alternate fuel type but is not labelled for use with that fuel type, it must be safety assessed before it can be operated
    • installing, modifying or relocating a Type B gas appliance, including converting the fuel type, must be tested and certified on-site by an accredited certifying body – see Gas product approvals for more information.

A gas certificate of compliance is not required for repairing broken-down appliances or for maintenance service work where the appliance is not modified from the manufacturer's specifications. Replacing parts on an appliance with original manufacturer parts preserves any appliance warranties and existing appliance certification.

Gas fitters can use certificates of compliance as a record of work they have performed at a property, to distinguish it from other work that may have been done, and to formally notify the owner/operator of any gas safety issues that need to be fixed.

Only people with an appropriate licence can legally fill out a gas certificate of compliance and certify work. Refer to the Plumbers, Gas Fitters and Electricians Act 1995 for a definition of plumbing, gas and electrical work and the requirements for a person to hold an appropriate licence.

Electronic certificates of compliance

Electronic certificates of compliance (eCoCs) may be used in place of paper certificates of compliance, which will be discontinued on 30 June 2018.
