Guaranteed Bill makes it easy for you to do monthly budgeting. You pay the same amount every month for 12 months, regardless of the weather and changing gas prices — guaranteed!
Know What You're Paying Each Month
We base your Nicor Advanced Energy Guaranteed Bill amount on several factors, like average weather, gas prices and your monthly gas usage in the past. Lock in before the next heating season when cold weather can play havoc on your gas bills.
