I've been tempted to switch for a while but, I haven't yet. I get a lot of mail advertising but they don't tell me much.  I want to know if I have to sign up for a minimal amount of time to get the discount. Can I switch again if I'm not happy? Too much missing fine print I guess, lol. I'm interested to hear from someone who has.

Jen,
i'm a disabled bet and would like to enjoy some relief on my energy bill, but i suspect switching would result in minimal savings.
i would like to know of real experiences with this program.

You'll notice a savings for the first two or three months on the supply cost but after that, it goes back up to the going-rate which is normally within a few cents of the Utility company. That's why, if you're considering a switch now would be the time to do it, since it's heating season.  When you get an offer, make sure to ask plenty of questions.  In most cases an ESCO won't require you stay with them for a fixed amount of time (meaning, normally you can opt out at any time if you're not satisfied with savings)

it is definatly not worth switching energy suppliers i was with a different supplier for two years and thought that i was getting a great deal until i talked to my mom to see what her charges were because i thought mine were rediculusly over priced and come to find out they were so if i were you i would stay with national grid.

Jen, I saw your report and said I need to send you my experience.  I had one of these companies call my house to switch over.  My wife told the gentelman nicley that we were not interested and hung the phone up.  The phone rang back, it was the same man.  I took the phone and told him the same thing and did the same thing.  He called back again and was very nasty to me on the phone.  I hung up on him then.  He called back and wouldnt say anything.  Good thing for caller ID.  I tried for two hours afterwards to get a hold of them to talk to a supervisor.  I havent heard back from them yet.
