We calculate how much energy we think you'll use over a year and divide that by 12 to work out a monthly direct debit amount.

When you join Economy Energy, we work out how much energy we think you’ll use over the year. This is calculated taking into account factors like the size of your home, what you’ve used in the past and that you’ll use different amount of energy throughout seasons. Then we divide that cost by 12 to work out your monthly payment.
