Certificate of Gas Safety
A Certificate of Gas Safety is an official document issued by an EMA-licensed gas worker after inspecting and verifying that your home's gas installation meets Singapore's safety standards.
A Certificate of Gas Safety is an official written statement issued by a Licensed Gas Service Worker (LGSW) after completing a gas appliance installation, maintenance, or repair. It is not an optional courtesy document — it is a legal requirement under Singapore's Gas Supply Regulations, and it confirms that your gas appliance and its connections have been tested and verified safe for use.
What the Certificate Records
How the Certificate Is Issued — The Commissioning Sequence
The LGSW conducts a final pressure test on the gas pipe and connections to verify there are no leaks. This test is measured on a gauge — the result is visible and recordable.
The technician confirms that gas is flowing correctly through the system and that the appliance is operating within safe parameters.
The LGSW completes and signs the Statement of Gas Appliances Testing. The customer's copy is issued at this point — before handover.
The job is handed over to the customer with the signed certificate in hand. The customer acknowledges the completed work by signing the document.
Under Singapore law, no person shall use a gas appliance that has not been certified safe for use. Any person who contravenes this requirement may be liable to a fine not exceeding SGD 5,000. The Certificate of Gas Safety is the document that satisfies this legal requirement — keep your copy.
