Caporegime
We're now in the middle of January, my monthly DD is £188, I'm £900 in credit, and the last bill in December was for £196.50 for both types of energy combined.
What sort of refund would you be asking for? (I'm on Octopus Tracker)
Like...£800 at least.
If you are basically using up your entire DD amount in the depths of winter you can probably knock 1/3rd off it and still end up not having to worry about it not averaging out over the year.
