That is good news. But I've just signed up to a fixed tariff.

I don't have exit fees so I could come out of it but I'm sure I won't get a better deal before the next Ofgen price cap. Maybe there might be better fixed tariffs around now.
Saying that, they always lower the price in the summer months you don't save anywhere near the amount they state anyway. So it's a bit of a con as they'll put it up again around autumn when you'll use more.
