I just thought I’d post this as I’m sure there are a few people in the same position.
I tried to work out how much my bill would be for last month and my calculation result scared me. I worked it out to cost £164 which is 4 x my current PP rate. It was my gas price that was way high so I think I must’ve typed in the wrong number into the calculator. I contacted Shell on Facebook messenger and they said that even though my account is not up and running and probably won’t be until nearer the end of the year, if I send them my usage they can tell me how much it would have cost. They did a calculation and my bill is actually closer to £57. I feel a lot happier at that, moral of the story I clearly can’t do maths
I just thought I’d post this in case others have done their own calculations and they are high. Even though your bill will have gone up due to the new rates Shell will be able to tell you how much it will be. Could help some people with budgeting.
