My account is in credit – why has my Direct Debit gone up?
Your Direct Debit payments spread the cost of your energy evenly over the full course of the year. If we think you're not building up enough credit in the summer to cover your winter use, we may put up your Direct Debit.
We set your monthly Direct Debit amount by estimating how much energy we think you’ll use over the next 12 months. We divide the total by 12 so you pay the same Direct Debit amount each month.
If your Direct Debit is set at the right amount, you'll build up enough credit over the summer to cover the cost of your higher winter energy use. At the end of your billing year, you will have paid the right amount for the energy you’ve used.
We may review your Direct Debit payments when we get a meter reading. If we see you're not building up enough credit in the summer to cover your winter energy costs, we may put up your Direct Debit.
