So I switched and within 2 months my direct debit is increased to what it was with Eon?? And I could have negotiated a better deal with Eon before leaving??
There has been massive industry increases and probably more to come, without checking I suspect EON will also have price increases.
I would do another price check/switch before you decide.
If you do decide to move again there are no exit fees. You can of course alter your dd to suit if you think it is too high compared to your usage.
