Fixed Rate Savings

Fixed rate contracts are a better deal with alternate suppliers. You can save on the rate you pay for natural gas per therm or electricity per kilowatt-hour with a fixed rate plan because it protects you from market price fluctuations over time. We recommend natural gas contracts of 12 months or fewer, and electricity plans last 18 months or more.

Variable rate plans can end up being more expensive than your local utility, because they are not regulated by your state government. For this reason, we do not recommend variable rate plans with alternate suppliers.


Customers can earn points each time they pay their bill with Marathon Energy. One point is equivalent to 1 natural gas therm, or 10 electricity kilowatt-hours. After earning 1,000 points, customers get a prepaid visa card worth $10 from Marathon Energy.

Customer Reviews

Marathon Energy earned an A+ score from the Better Business Bureau for its customer service, because the company has handled official concerns effectively and rapidly.

However, some customers feel that the company may contact them excessively via telemarketing sales.

Check out more detailed feedback, including our take, in our Marathon Energy customer reviews page. You can also compare reviews with other alternate suppliers.

Marathon Energy provides services like home energy audits, which help customers to improve home energy efficiency, reduce waste, and potentially save on their energy bills. The company also installs equipment like boilers and burners, and it provides maintenance and repair to customers' heating equipment.
