If you can smell gas now: do not touch a switch or light. Close the cylinder valve, open windows and doors, get everyone out, and call from outside.
Gas work is legally restricted to installers registered with SAQCC Gas. Water leak services sit under Leak Detection Cape Town.
Tell us the appliance, the cylinder size and whether you can smell gas.

- The added odourant, which smells like rotten eggs. LPG itself has no smell.
- Hissing at a regulator, hose or fitting.
- A cylinder emptying faster than the usage explains.
- A yellow or orange flame where it should be blue, or soot on a burner.
- Frost or condensation on a regulator or line.
How Gas Leaks Are Found
- Pressure drop test - the installation is isolated and pressurised, and the gauge is watched. It proves whether the system holds.
- Electronic gas detector - a sniffer traced along the run to find the point.
- Leak detection solution - applied at joints and fittings, where it bubbles at the escape.
- Appliance and combustion check - burner, regulator and flue condition.
The Certificate of Conformity
A gas Certificate of Conformity is required for a new or altered LPG installation, and is normally requested on property transfer and by insurers after any gas incident. Only an installer registered with SAQCC Gas may issue one, and the certificate covers the installation as it stands on the day.

Gas work is not a general plumbing job. Ask for the installer's SAQCC Gas registration number before they start, and check it is current.

Frequently Asked Questions
What do I do if I smell gas?
Close the cylinder valve, open windows and doors, and get everyone outside. Do not operate any light switch, appliance or phone inside the building, and do not light anything.
Call for help from outside the property and do not go back in until it has been checked.
Who is allowed to work on a gas installation?
Only an installer registered with SAQCC Gas. A general plumber or handyman may not legally work on an LPG installation or issue a Certificate of Conformity.
Do I need a gas certificate to sell my house?
A Certificate of Conformity is required for any new or altered gas installation, and conveyancers and insurers routinely ask for one on transfer where a fixed gas installation is present.
Why does my gas cylinder empty so quickly?
Either usage has changed or gas is escaping. A pressure drop test settles it: the installation is isolated and pressurised, and a falling gauge proves a leak.
