The complaints filed against providers aren't a perfect mirror of the J.D. Power customer satisfactions scores. Just Energy, which earned only two J.D. Power Circles and earned the second-lowest score, had only 21 complaints recorded with the Public Utility Commission. But it's helpful to view these complaints in aggregate: Over 50 percent of the 1,119 total complaints fall under "billing" — another reason to seek out a provider with high customer satisfaction in that area in particular.

According to the EIA, the average American household uses 897 kWh of energy per month. Knowing that number, and how your own home’s usage compares, provides insight into the amount of energy you use per device. Our Energy Estimator will show you why simple changes like programming your thermostat or turning off televisions and computers when not in use will help lower energy costs.
This means that you need not be concerned about a fall in customer service, when you change to a cheaper gas and electricity supplier. You will be able to easily compare all of the energy options available to you. You will be able to hear from existing customers about the experiences that each one has had with every energy supplier that we display.

Fixed-rate, long-term (contract) plans provide stability in electricity rates. If market energy costs suddenly trend upward where you live, you can rest assured that you won’t have to pay more out of pocket. However, if you want to switch to a different, lower-cost plan before the end of the contract term, you’ll likely have to pay a cancellation or early termination fee.
