should we switch now?

are you tied in for x amount of months if you switch to a new supplier now. if they increase their prices are you commited to staying with them.

It really depends on what type of contract you are on, I think, no sure really.
But if it doesn't stipulate so, you are free to change suppliers as many time as you want as long as you don't owe them money.

Have you moved house recently? I'm wondering whether you could be tied in if you had just moved house and it was a new supply, that is the only way I could see of you being tied to a supplier. That and owing them money.
