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 intends trialling the use of the downloadable NOI from the website.  If the trial is successful Building and Energy intends to seek approval to amend the regulations to make submission mandatory.

When should you complete an NOI?

An 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 can submit an NOI?

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.

Complete these rows.  Provide directions to allow easy location of the gas installation if there is only a lot number.

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
