Your monthly Direct Debit amount is based on how much energy we think you'll use over the year. This is known as a personal projection.
 
 
You tend to build up a credit balance in the summer when you're using less energy, which goes towards your costs in winter when you're using more.
 
If your payments are too low for the amount of energy you're using, you'll build up a debit balance on your account.
