Gas system compliance certificates and plates

Gas system compliance certificates can be issued electronically, via an e-certificate, or by a carbon copy certificate book.

From 1 January 2026, all gas system compliance certificates must be issued online.

E-certificates

RSHQ is phasing out the use of hardcopy books and transitioning to e-certificates. Once issued, you will receive a PDF document that you can send onto your customer, the network provider and keep for your own records.

Available options include:

• gas system compliance certificate
• gas system defect notice
• vehicle/vessel gas system inspection certificate.

Requirements for completing installations

When you complete an installation you must:

• give the owner or operator of the system the original copy of the gas system compliance certificate or email them an electronic copy of their e-certificate
• attach a gas system compliance plate or update the existing plate with the work you carried out. The plate shows the history of gas installation and who undertook the work. Read more about the requirements for installing compliance plates (PDF, 568KB)
• if the system is supplied with fuel gas by a distribution system or fuel gas network, give the operator of the system/network the second copy of the gas system compliance certificate or email the e-certificate within 5 business days after completing the installation. Read further information on requirements before starting work and information on contact details for operators
• retain the third copy of the gas system compliance certificate for your records for at least 3 years.

Defect notices

If you have any safety concerns about a gas system you are working on, you must give the owner or operator a defect notice.

If you believe there is an imminent risk of material harm to persons or property, you must also:

• take appropriate measures to avoid, eliminate or minimise the risk
• immediately report the risk and measures taken by phoning
  • the operator of the distribution system or fuel gas network
  • the Petroleum and Gas Inspectorate.

You do not need to give a defect notice if action is taken to immediately remedy the safety concern (e.g. you carry out gas work to immediately remedy the concern).
