After an electrical, gas or plumbing tradesperson completes work on your property, by law they must issue you with an electronic certificate of compliance (eCoC).
eCoCs are emailed to you. If you don’t have access to email, the tradesperson must print the eCoC for you.
The tradesperson, and any contractor involved in the work, must both sign off on the eCoC. These certificates confirm that:
- the tradesperson is correctly licensed
- the completed work:
- has been tested
- is safe
- meets the Australian Standards
- the contractor has informed you of any existing safety concerns.
You must receive an eCoC (once the job is completed) within:
- 30 days - electrical or gas
- 7 days - plumbing.
Electrical
Electricians must give you an eCoC for most of their work. This includes any electrical tests and checks.
Certificates aren't required for minor maintenance, such as replacing lightbulbs.
Gas
Gas fitters must give you an eCoC for:
- work on gas pipes
- installing or replacing appliances, such as hot water units and stove tops
- converting to an alternative gas, for example from LPG to natural gas.
Certificates aren't required for repairs or maintenance on an existing appliance.
Plumbing
Plumbers must give you a plumbing eCoC for:
- pipework and fixtures from the mains water supply or sewer
- sanitary plumbing and drainage
- installing or replacing a water heater
- work on a backflow prevention device
- installing an alternative water service
Certificates aren't required for:
- changing tap washers
- clearing blocked drains
- installing domestic tapware
- installing stormwater systems.
Without an eCoC for these works, insurance companies could refuse claims if the related works cause a fire or damage.
Contact the Office of the Technical Regulator if a tradesperson is refusing to provide you with an eCoC.
