Southern California Gas Company, which serves most of Southern California, sends bills to approximately 24 million consumers. Your bill typically arrives monthly and covers the gas you used during a specific billing period—usually around 30 days. The bill shows not just what you owe, but detailed information about your consumption patterns and the various charges that make up your total amount due.

The main sections of your bill include customer service charges, gas charges based on your usage, delivery charges, and taxes. Each of these represents a different cost component. For example, if your bill is $85, you might see $15 for customer service charges, $35 for the actual gas commodity, $30 for delivery, and $5 in taxes. These proportions vary based on market conditions and your usage level.

Your bill also shows your account number, service address, billing period dates, and payment due date. The due date typically appears prominently near the top or bottom of your bill. Most bills must be paid within 20-30 days from the billing date. Paying after the due date may result in late fees or service disconnection notices.

Practical Takeaway: Locate these five items on your next bill: your account number, billing period dates, total usage in therms, total amount due, and payment due date. Keep this information handy for future reference or when contacting customer service.

Breaking Down Each Charge on Your Bill

Your gas bill contains several distinct charges, and understanding each one helps you see where your money goes. The largest charge for most households is typically the gas commodity charge—this is the actual cost of the natural gas you used, measured in units called therms. One therm equals approximately 100,000 British Thermal Units (BTUs), the standard measurement for gas heat content. The price per therm fluctuates based on wholesale gas markets and is adjusted monthly.

The delivery charge covers the cost of maintaining the pipes, meters, and infrastructure that bring gas to your home. This charge includes system maintenance, meter reading, billing and collection, customer service, and infrastructure upgrades. Delivery charges are typically the second-largest component of your bill. Unlike the commodity charge, which can fluctuate significantly, delivery charges change less frequently and follow rates approved by the California Public Utilities Commission (CPUC).

Customer service charges cover the cost of running the company's operations—billing, customer service centers, safety programs, and regulatory compliance. This is sometimes called the basic service charge or customer charge. Most households pay between $10 and $20 monthly for this charge, regardless of how much gas they use. Some months you might see additional charges for services like reconnection fees if your service was interrupted, or charges related to specialized meter reading.

Your bill also includes public purpose program charges. These charges fund programs that benefit low-income households, support energy conservation initiatives, and fund renewable energy development across California. These charges typically add 5-10% to your total bill. Finally, state and local taxes are applied to your bill—usually around 8-12% depending on your location within Southern California.

Practical Takeaway: On your next bill, write down the per-therm commodity price and your total therm usage. Compare this to next month's bill to understand how your usage and market prices affect your charges. This awareness often leads to more conscious usage decisions.

How to Calculate Your Gas Usage in Therms

Your gas usage is measured in therms, and your bill shows exactly how many therms you used during your billing period. To understand this measurement, it helps to know what a therm represents and how it's calculated. One therm is a standardized unit of energy equal to 100,000 BTUs. Most household activities that use gas—heating water, cooking, and space heating—consume a certain number of therms depending on how long and how intensely you use them.

Your meter measures your gas consumption in cubic feet. The gas company converts cubic feet to therms using a formula that accounts for the gas temperature, pressure, and specific gravity (density). You don't need to do this calculation yourself—it's shown on your bill. However, understanding the relationship helps you interpret usage patterns. On your bill, you'll see the meter reading from the start of your billing period and the meter reading from the end. The difference between these two numbers, divided by a conversion factor, gives your therm usage.

Seasonal usage varies significantly for most households. During winter months (November through March), usage typically increases because more gas is used for heating. A typical Southern California household might use 20-30 therms during a mild winter month and 40-60 therms during the coldest months. Summer usage (June through September) drops considerably because heating is not needed. Summer bills might show 5-15 therms, primarily from water heating and cooking.

Understanding your average monthly usage helps you budget and identify unusual bills. If your bill suddenly shows significantly higher usage than the same month last year, it might indicate a problem like a running pilot light, a heating system malfunction, or simply colder weather than usual. Conversely, lower-than-expected usage might indicate meter reading errors or that you were away for part of the billing period. You can use past bills to calculate your average usage and notice trends throughout the year.

Practical Takeaway: Gather your last 12 bills and create a simple table showing the therm usage for each month. This 12-month history shows you your seasonal patterns and helps you recognize if any particular bill is unusual. It also helps you predict approximate costs for budget planning.

Payment Methods and Due Dates Explained

Southern California Gas Company offers multiple ways to pay your bill, each with different timing and convenience features. Understanding these options helps you choose the method that works best for your situation and avoid late fees. Your bill clearly shows the payment due date, typically 20-30 days after your billing date. Payments are considered on time if they are received by the due date, not if they are sent by that date.

Online payment through the company's website is one of the fastest methods. You can pay using a checking account (eCheck), debit card, or credit card. Online payments typically process the same day you submit them if you pay before the cutoff time, usually around 5 PM Pacific Time. The company's website allows you to set up automatic payments that occur on a schedule you choose, such as the same date each month. This method reduces the risk of forgetting a payment and ensures consistent on-time payments.

Phone payment is available by calling Southern California Gas Company's customer service line. You can speak with a representative who will process your payment using your bank account or credit card. Phone payments have similar processing times to online payments. Some customers prefer this method because they can ask questions while making their payment or confirm that their account is current.

Mail payment remains an option, though it's slower than electronic methods. If you pay by check or money order sent through the mail, allow at least 7-10 days for delivery and processing. The bill includes a payment envelope with the address where to send payments. Write your account number on the check or money order to ensure proper credit to your account. Mail payments that arrive after the due date will be considered late, even if you mailed them before the due date.

In-person payment locations include many retail stores and bank branches. These locations accept cash, check, or card payments and process them immediately. This method is useful if you prefer handling payments in person or if you need to pay in cash. Payment history shows on your account within 1-2 business days of in-person payment.

Practical Takeaway: Choose a payment method and set a calendar reminder for one week before your bill's due date. This buffer gives you time to process the payment without rushing and reduces the chance of accidental late fees.

Managing High Bills and Investigating Unusual Charges

If your bill is significantly higher than usual, several factors might explain it. The most common reason is seasonal variation—winter months naturally have higher usage because heating accounts for 40-60% of residential gas consumption in Southern California. A colder-than-normal winter or more days of heating use will increase your bill. However, if your bill is higher than the same month in previous years, other
