“  Upon getting what I thought was first bill it had an inappropriate rate assigned to it. Called customer service and was explained meter reading date was the issue. Subsequent bill was correct. ”

Very Easy to work With

(4.6 / 5)

“  My experience with Constellation has been great. One short call and everything was setup. The CSR did not make me do anything online. She just did it all for me over the phone and service was installed and has been great this past year. ”

Timing is Critical

(4.6 / 5)

“  I switched from a 18 month account with Scana to a 2 year account with Constellation. Unfortunately, it is difficult to time the signup so I was left with 2 months on my old contract and was billed $200 cancellation fee. Having been stuck before with a month between contracts and paying 300% premium during the winter, more help with timing from one contract to the next would be nice. Lucky for me Constellation is helping with $150 of the charge.....thank you!!! ”

Constellation Review

(4.6 / 5)

“  Constellation was recommended to me by my sister. It was easy to sign up for service. Information about usage came to me via email and online payment was easy. I hope I can continue with Constellation with their great prices, but like with everything else, I expect a price hike after my initial sign up contract expires. ”

Happy customer hate the rate change

(4.6 / 5)

“  I have really been a very happy customer from day one with constellation the service is great the prices have been great I'm very sad that I did not sign up for a longer-term because now it's about to go up 2 point 9% and that's going to throw me off my fixed income which may force me to have to look for another company only so I can afford to pay the bill not because I have any complaints with the company at all they have been great. ”
