Very good 24 month deal

(4.2 / 5)

  The only problem is that if you chose to pay online at they website,there is a $2.95 charge.
At my previous companies,Infinity Energy or Atlanta Gas,there was no online charge.
On the good side,i can avoid this charge by paying online thru my bank.
But the reason i was paying to the gas companies directly was to make points to my credit card.

Better pricing

(4.2 / 5)

  I had been with another provider for more than 2 years at a rate of $.49 per therm. I admit that it was my fault that I did not go back to request another contract price. However, any good provided would have alerted me to ask for another price so that they could keep my business. Instead they decided to raise the rate to $ 1.196 per therm. Even if they had been $ .10 per therm more I would have likely stay with them. Anyway what I did was to look for a better deal and I was obliged to go Constellation for a two year deal which was 1/3 the price of my old provider and Im now very pleased with the outcome and I will like stay with Constellation.

Good Plans

(4.2 / 5)

  The price plans were pretty good, but I would have liked more customer service help. I had some difficulty figuring everything out and it would have been nice to speak to someone.

Poor customer service

(4 / 5)

  Customer service called and offered a reasonable price for electric, only to find out later we can not use Constellations, if we do not use National Grid.
We are allowed to choose our electric company, but not our gas supplier

Read the EFL fine print

(4 / 5)

  Order was easy. Account transfer no problem. First bill was higher than EFL facts said it was going to be. The distribution charge from the electric distributor was about $10 higher than what EFL said. Called Constellation and asked why, they said distribution charges had gone. They went up the first month after I switched. False advertising by Constellation.

Good ride for 10 months

(4 / 5)

  Had some billing issues early on, but not exactly providers fault. All in all everything was great, however as always good things don't last. Provider probably won't make my current plan available on renewal as it was more likely promotional to attract business, so will have to look for affordable options elsewhere to keep costs in check

Review

(4 / 5)

  There should be an online method to renew policy... Either I was not patient or the rep talked slowly, either way when I'm at work taking the time out for all the repeated question was a bit weary. When someone satisfied with the services, the option to renew is given.
