Installation Process

Whether you are building a new home or converting an existing home to gas energy, Hawaiʻi Gas will help you every step of the way. The process can seem overwhelming at first, but with a Hawaiʻi Gas Account Executive assigned to your installation, you can rest assured that you’ll be enjoying the benefits of gas energy powering your home in no time.

Step 1 icon

Check Gas Service Availability

Contact Hawaiʻi Gas to speak to a residential gas installation expert; they will help you determine whether you have a natural gas line nearby or if your gas service will be propane. If you are in a Hawaiʻi Gas pipeline subdivision on Oʻahu, we can connect your home to one of our reliable utility systems. If your home is located away from a pipeline, or on a neighbor island, Hawaiʻi Gas can provide a propane cylinder or tank delivery options to serve your home energy needs.

Step 2 icon

Hire a Plumber

While we check on your gas service availability, take the time to locate a plumber. A licensed plumber is required to help you install your gas line and equipment in your home. Hawaiʻi Gas will take care of everything outside your home which, depending on the gas service availability, may include connecting to an existing underground pipeline, or installing a propane cylinder or tank. We will be sure to coordinate with your chosen plumber to take care of everything else after that.

Here is a list of licensed plumbers to get you started.

Shop for the Best Offers

Before you select your gas appliances or equipment, you may want to check with your appliance dealer or plumber for equipment options. Here is a list of appliance dealers to help you get started. Remember that propane and natural gas require slightly different appliance specifications.
Plus, check out our Hawaiʻi Gas Rewards for credits that you could apply towards your account.

Step 4 icon


Once you decide on your energy needs with our Account Executive, we will place an order for installation of a gas service line or cylinder/tank service to the home.

Step 5 icon


If required, Hawaiʻi Gas will obtain the necessary permits for gas service line work outside the home. Your plumber will be responsible for obtaining any required permits for the equipment and gas line inside the home.

Step 6 icon

Call Before You Dig

Before you dig anywhere on your property, call “811.” You may see some painted marks on the sidewalk or road near your property. These marks are part of a nationwide “Call Before You Dig” program that indicates the location of your water, phone, sewer, and electrical lines and the gas main in the street.

Step 7 icon

Gas Service Installation

After all permitting has been processed, if your home is being connected to a utility pipeline on Oʻahu, a Hawaiʻi Gas crew will be scheduled to install the service line from the street to your home and set the meter.
If your home is not connecting to a utility pipeline (or on a neighbor island) and you will receive cylinder/tank service, one of our Customer Care Representatives will contact you to schedule a time a Hawaiʻi Gas crew can install the cylinder or tank and gas line on your property.

Step 8 icon

New Gas Appliance Installation

Ask your Hawaiʻi Gas Account Executive for information on the installation of your gas equipment and he or she will be happy to walk you through the entire process.
Please work with your contractor to review our new installation checklist prior to turning on gas service.

Step 9 icon

The Inspection Process

Your plumber is required to obtain all necessary permits and perform pressure tests on your houseline. If the houseline passes the pressure test, an inspector will attach a "green tag." This step must be completed before Hawaiʻi Gas can activate your meter or cylinder/tank service.

Step 10 icon


Once the inspection is completed, we will turn on the gas to your home. That means you can relax and enjoy the performance, comfort, and peace of mind that our gas energy provides!
