Fact sheet - converting gasfitting certificate of competency to permit
This fact sheet explains what your entitlements are and how to obtain a gasfitting permit when surrendering your certificate of competency to Building and Energy.
Certificate of competency (CoC)
CoCs were issued by the State Energy Commission (SEC) in the 1980's and early 1990's so that the holder could carryout gasfitting work. Each CoC carried an endorsement identifying a class of gasfitting which the holder could perform:
- Class A was for installation work where the gas in use was lighter than air i.e. natural gas;
- Class B was for service work on installations where the gas in use was lighter than air;
- Class C was for installation work where the gas in use was heavier than air i.e. LP gas;
- Class D was for service work on installations where the gas in use was heavier than air;
- Class E was for the installation on LP gas vehicle engines in accordance with AS 1425; or
- Class F was for service work on LP gas vehicle engines which complied with AS 1425.
In the early 1990's the issuing of CoCs was phased out in favour of permits as the primary licensing method for gas fitters.
The Gas Standards (Gasfitting and Consumer Gas Installations) Regulations 1999 were introduced in 1999. These regulations better reflected the needs of industry by referencing national standards and introduced a more appropriate gas fitter classification system:
- Class G (general gasfitting) issued for gasfitting on consumer gas installations associated with Type A gas appliances (listed in the regulations) and piping systems operating up to 200 kPa;
- Class I (industrial gasfitting) issued for working on Type B gas appliances and piping systems operating above 200 kPa;
- Class E issued for working on mobile engines, cars or marine craft operating on gas; and
- Class P issued for working on auto gas refuelling facilities.
All classes of gasfitting may be restricted e.g. restricted to installation or to LP Gas only etc.
