While billing errors are uncommon, they do occur. Knowing how to verify your Atlanta Gas Light bill helps you catch mistakes and ensures you're only paying for gas you actually used. This guide walks through the verification process step by step.
Most billing discrepancies result from estimated readings, meter reading errors, or incorrect rate application. A few minutes of verification can save you money and prevent ongoing overcharges.
Step 1: Check Your Meter Reading
The first step is comparing your bill's meter reading to the actual meter. Your gas meter displays a reading in cubic feet (CF or CCF). Record this number and compare it to the "current reading" on your bill.
If the bill shows a higher reading than your meter, you may have been overcharged. If lower, expect a catch-up charge on your next bill. Note that readings should be taken at approximately the same time as the billing read date for accurate comparison.
Step 2: Verify Usage Calculation
Your therm usage should equal the difference between current and previous meter readings, multiplied by a conversion factor (approximately 1.03). Check that:
- Previous reading matches last month's current reading
- Usage calculation is mathematically correct
- Usage seems reasonable for the season and your household
Unusually high usage with no change in habits may indicate a gas leak, malfunctioning appliance, or meter problem.
Step 3: Verify Rate Application
Check that the rates applied match your contracted rates:
- AGL delivery charges: Should match current tariff rates
- Marketer supply rate: Should match your contract terms
- Customer charge: Should be $20.00 for residential
If you're on a fixed-rate plan, your supply rate should be consistent month to month. Variable rates will change but should match published rates for that month.
When to Request a Review
Contact AGL or your gas marketer if you find:
- Meter reading doesn't match your meter
- Usage is significantly higher than expected with no explanation
- Rates don't match your contract or published tariffs
- Charges appear that you don't recognize
