After gasfitting work in NSW, the responsible appropriately licensed gasfitter must inspect and test the installation and complete the required compliance documentation. The document depends on whether the property receives gas from a distribution network or a non-networked supply such as bottled LPG.
Which document applies?
- Gas supplied through a distribution network: The gasfitter completes a Certificate of Compliance for the gas installation.
- Non-networked bottled LPG: The gasfitter completes a Certificate of Inspection and affixes a compliance plate to the installation unless the installation is found to be defective.
A fixed cooktop supplied by a 9 kg LPG cylinder generally still requires licensed gasfitting work and the applicable documentation. The bottle’s size does not make a fixed installation exempt. This does not include portable, self-contained camping appliances.
Other gas cooktop installation requirements, including clearances, ventilation and appliance suitability, must also be checked before the connection is commissioned.
Who completes and lodges the documentation?
The responsible gasfitter must complete the certificate. Since 1 March 2026, NSW gasfitters must submit Certificates of Compliance and Certificates of Inspection through the Building Commission NSW eCert portal within five business days after the work.
For a network gas installation, the gasfitter tests the installation for defects and submits the Certificate of Compliance. For a non-networked installation, the gasfitter must complete the required inspection and testing, provide the Certificate of Inspection to the owner and attach the applicable compliance plate.
Only an appropriately licensed gasfitter can complete this work. Homeowners must not connect, alter or test gas pipework or fittings themselves. If the work involves a cooktop, check which licensed trades the installation requires before booking it.
What should the owner check?
- Licence: Confirm the installer is appropriately licensed for gasfitting work in NSW.
- Certificate type: Ask whether a Certificate of Compliance or Certificate of Inspection applies.
- Record: Keep the certificate or electronic record provided for the installation.
- LPG compliance plate: For non-networked LPG, check that the applicable plate has been fitted.
If you did not receive documentation, contact the original gasfitter. If they cannot provide or confirm it, ask another appropriately licensed gasfitter to assess the installation. They may need to inspect and test it and cannot simply certify unseen work.
Do not use or alter a connection you suspect is unsafe. If you smell gas, avoid flames and electrical switches, leave the area, and turn off the supply only if it is safe. From outside, contact your gas distributor’s emergency service or call 000 if there is immediate danger.
Contact our Sydney gas cooktop installation team to arrange an appropriately licensed gasfitter if the installation or its documentation needs assessment.
