Why have I paid 13 Direct Debit payments in a year?

Direct Debit is designed to spread your energy cost evenly over 12 monthly payments. But occasionally, we may take 13 payments over the course of a year.

There are two possible reasons for this:
1. You submitted your meter reading too early
2. You had an outstanding balance when you set up your Direct Debit

Even though you've made a 13th payment in the year, you still only ever pay for the energy you use. All your payments are taken into consideration when we review your Direct Debit payments.

1. You submitted your meter reading too early

We usually set your Direct Debit payments for the next billing year as follows:

  • We carry out an annual review of your account at the end of your billing year.
  • This involves estimating how much energy you'll use up until your next annual review (usually in 12 months' time).
  • We divide your estimated annual energy consumption by 12 to set your monthly Direct Debit payment amount for the coming year.

But because you submitted an early meter reading, the process changed:

  • Your early meter reading triggered an early annual review.
  • This meant there were 13 months to go before your next annual review.
  • So we divided your estimated annual energy consumption by 13 to set your monthly Direct Debit payment amount.

2. You had an outstanding balance when you set up your Direct Debit

We took a payment from your bank account to cover your outstanding balance when we first set up your Direct Debit (unless you'd agreed a payment plan to pay off the balance). This was in addition to the 12 monthly Direct Debit payments you made for the rest of your billing year.
