How to Read Your Bill


Because utility commission guidelines and requirements differ in the areas we serve, your bill may differ from those in other Southwest Gas areas. In an effort to help you understand your bill, we placed an example of your bill online and provided an explanation of the various items on it. Please begin by selecting the area in which you live. These examples are not intended to represent a true comparison in usage or average costs between areas we serve.
Southwest Gas bills its customers on a per-therm basis, i.e., for the amount of energy contained in the gas delivered. The current reading minus the previous reading, times the billing factor, equals the number of therms you have used in the current billing period.
The monthly bill is due and payable upon presentation and becomes past due if not paid by the "Due Date" on your bill. A late pay charge will be added to the bill if payment is not received before the next bill is rendered. Check out the  How Gas Rates Are Set page to learn more.
If you smell gas or have a gas safety issue,check out the Home & Business Safety page for further instructions.
You may pay your bill automatically online, by mail or in person at a Southwest Gas Business Office or authorized payment location. Use our payment locations map to find a location near you (convenience fee may apply). 


More than 177 million Americans use natural gas to cook a hot meal, heat their water or warm their houses. Many parts of the country have felt the chill of winter and that means folks are using more natural gas. The American Gas Association has developed a video to explain what goes into your natural gas bill.
