How are my monthly advances calculated?

Natural gas

Gas customers are billed on the basis of monthly advances and an annual bill. Each advance is 1/12th of the estimated annual consumption. When we establish your annual bill, we will adjust the amount of your monthly advances depending on your consumption during the past year. On your annual bill, you will find a table listing the upcoming advances. If you choose to pay by direct debit, the advance bills are replaced by a payment schedule that the bank uses to debit the correct amounts from your bank account.

Electricity

Electricity is billed monthly based on your actual consumption, provided your smart meter communicates the relevant data. In the rare case where your data is not available, we will inform you and offer you to be charged on the basis of advance payments and an annual bill.
