The company that provides me with gas (methane/ethane/propane/dunno) and electricity rips me off by a little over €600 a year I found out today.. whilst comparing providers online. Those frikkin' mother fuckers. I'm going to look into the fee part (for breaking the contract) tomorrow and will take action/change provider of both.. if that's the sensible thing to do.
Most other providers will be happy to pay said fee for you, if you change.
But, they don't have to be cheaper for real.
I changed a while ago, got a welcome gift, and my fee paid. Turned out, they were not cheaper, there were some hidden costs. So, within a year, I went back to my old provider, who was willing to pay the fee for leaving the new one. I did end up with a better contract than I had in the beginning with the same provider I was with before switching.
