Gas Standards (Gas Supply and System Safety) Regulations 2000
The Gas Standards (Gas Supply and System Safety) Regulations 2000 mandate the following:
- AS 2885.1 Pipelines - Gas and liquid petroleum - Design and construction
- AS 2885.3 Pipelines - Gas and liquid petroleum - Operation and maintenance
- AS/NZS 4645 Gas distribution networks
- AS 4564 General purpose natural gas
- AS 4670 Commercial propane and commercial butane for heating purposes
- AS 4647 Diaphragm gas meters
Increasing competition in the gas industry has the potential to impact on the technical and safety standards of gas suppliers as they come under pressure to reduce costs to remain competitive. To safeguard the public and consumers in such a changing environment, these regulations have been introduced to ensure:
- the safety of the public, gas consumers and gas workers in the vicinity of gas distribution assets; and
- that gas supplies conform to acceptable standards of quality and metering accuracy to protect ordinary gas consumers.
For enquiries on this matter, please contact Building and Energy's Principal Engineer Gas Supply by telephoning (08) 6251 1900.
LP gas standards
The standards for LP Gas (liquid petroleum gas) are detailed in Part 2, Division 3 of the Gas Standards (Gas Supply and System Safety) Regulations 2000.
Further information about the introduction of the regulations is available on this page above.
Copies of the legislation may be obtained from the Legislation website.
Quality of supply
Part 2 of the Regulations specify the standards for natural gas and LP Gas. The metering accuracy for tariff customers of plus or minus 2 per cent and the prescribed minimum pressure to be supplied to a customer are also specified in these regulations.
Network operators
Refer to the Economic Regulation Authority for details of gas network operators.

Submitting a Notice of Intent (NOI)
The notice of intent (NOI) has been developed to advise the gas supplier of a likely significant future gas load that may impact on their supply infrastructure and enable them to monitor the progress of the gasfitting work being carried out.
Building and Energy is trialling the use of the downloadable NOI form.
View an example of a completed NOI form.
If the trial is successful, Building and Energy intends to seek approval to amend the regulations to make submission mandatory.
Completing an NOI
Show moreAn NOI is only required to be completed for the following installations:
- 'Multi-residential' is a development having 16 or more sole occupancy units or dwellings;
- 'Multi-storey' means three (3) or more storeys, excluding mezzanine or parking areas;
- 'Consumer piping nom. size greater than 32mm' means piping of nominal diameter greater than 32mm;
- 'Class I' is an industrial/commercial gas installation containing a Type B gas appliance; or
- 'Gas rate greater than 1,000MJ/h' is the total nominal gas consumption of all installed appliances exceeds 1,000MJ/h.
Who submits an NOI?
Show moreThe submitter advises the gas supplier of the future gas load. The submitter may be either a registered gas fitter or other design person (e.g. mechanical engineer, plumbing designer, hydraulic consultant, developer, project manager, architect, planner etc.).
Useful tips
- Download the NOI form from the Building and Energy website. You may print the form and complete it manually or save it to your computer as a master document for electronic completion.
- If saving the form for electronic completion, save information to be repeated on the 'master' form (i.e. Section 10 of the NOI that relates to the submitter).
- Open the 'master' form and click the 'Get a New Number' button and a unique number will be generated. Save the form using the NOI number and the name of the project for the file name. Complete the details of the installation on the form.
- Submit the form to the gas supplier as early as possible in the planning/design stage of a project and well before commencement (six weeks minimum where possible).
- Where the form has been submitted by email or facsimile, the original must also be submitted to the gas supplier or Building and Energy (where the gas supplier cannot be established).
- Keep a copy of the submitted NOI for your records.
Guide to completing an NOI form

Section 2 – Details of installation, gas supplier and retailer
Provide directions to allow easy location of the gas installation if there is only a lot number.
Section 3 – Fixed installation details
The meanings of the abbreviations are as follows:
- NG - natural gas.
- LP Gas - liquefied petroleum gas.
- Other - any other gas or pressure is to be stated.
Section 4 – Gasfitting work
Mark any of the boxes for the appropriate type of gasfitting work (multiple boxes can be marked). The meanings of these work types are as follows:

Section 6 – Type B (industrial/commercial) appliances
Provide full description, gas rate and whether pre-assembled, site assembled or a converted industrial/commercial gas appliance is to be installed under this notice (not existing or future appliances).
Provide the registration number of the independent designated Type B gas appliance inspector who is to issue the Certificate of Compliance.
