Gas work licence and authorisation holder obligations

Before installing new gas system or increasing demand on gas distribution network

Before you install a new gas system, or increase the demand by 100MJ/hour (or more), and the gas is supplied by a gas distribution system (metered), you must advise the network operator (gas supplier):

• about the works
• and
• the expected increase in demand for gas (how many MJ/hour).

Before installing new gas system or new gas appliances

Before installing a new gas system or installing an additional gas appliance you must ensure the gas supply is adequate to satisfy the additional demand for gas. Make sure you check the:

• LP gas cylinder storage and vaporisation rate
• gas meter and meter capacity
• pipe sizing.

After completing gas system installation or gas system alteration

When you have finished the gas system installation/alteration you must do the following:

• issue a gas system compliance certificate to the owner (immediately on completion) to certify the installation is compliant
• send a copy of the gas system compliance certificate to the network operator within 5 days
• attach a gas compliance plate to the relevant electrical meter box that identifies your licence/authorisation number, the certificate number, the date of the works and the relevant code for the works.
