I'm currently on a fixed rate with Scottish Power that ends on 30 Jan. They've offered me a new fixed rate for 2 years that will take my monthly payment from £130 to £170. I'm £260 in credit.
I've heard that it's better to not fix and move on to the standard tarif, but how do I work out how much the payment will be? I've heard energy prices are going to keep going up so would I be better to fix now rather than risk paying more in a few months time?
Hoping someone who understands these things will be able to advise - thank you.
