Selling a House in QLD? What to Know About the Gas Compliance Certificate
Short answer: Queensland has no separate, mandatory point-of-sale gas certificate requirement written into law the way it does for smoke alarms. In practice, though, most gas retailers won't connect or transfer supply to a new owner without evidence the gas system is compliant, so sellers who don't have a recent certificate on file commonly arrange one before settlement.
There's no separate "sale certificate" scheme
Unlike smoke alarms, which do have a specific point-of-sale compliance requirement in Queensland, gas compliance certificates work off the underlying rule described in our main QLD guide: a certificate is generated when gas work is done, not on a sale-triggered schedule. Selling a house does not, by itself, create a new legal requirement to reissue a gas compliance certificate if the existing system hasn't been altered and the last certificate on file is still accurate.
Where it becomes a practical issue is connection and continuity of supply. A gas retailer generally wants confidence the system is safe before it connects a new account at the property, and a valid compliance certificate (or a clean record of one lodged through the RSHQ Portal) is the evidence they look for.
What commonly happens around settlement
If a seller doesn't have a certificate on hand, or the property's gas system hasn't had any documented work in years, it's common for a real estate agent or conveyancer to recommend getting a fresh inspection and certificate before listing, to avoid a delay at settlement when the buyer's gas retailer wants to connect supply. This isn't a legal mandate, it's a practical way to avoid a stalled handover.
If you're buying rather than selling and settlement paperwork doesn't include a gas certificate, the same fix applies: book a licensed gas fitter to inspect the system after you take ownership, so you have your own current certificate on file rather than relying on an unknown history.
What a buyer or seller should actually check
Ask whether the property has reticulated natural gas or bottled LPG, since the compliance detail differs slightly between the two. Ask for the most recent gas compliance certificate and confirm the licensed fitter's details on it. If there's no certificate, or it predates a renovation, treat that as a reason to book an inspection rather than assume the system is fine.
