scope:

This International Standard specifies the minimum requirements for billing of all consumption-based utility network services to domestic customers. It covers the processes required to produce the bill and to deal with issues that arise after the bill has been sent, as well as the content of the billing document or statement. This International Standard is applicable to utility network services that are unmetered, metered at the point of delivery or metered remotely (e.g. on the supplier's own premises), and it covers any unmetered or unmeasured charges appearing on the same bill as metered or measured charges, as well as flat rate charges. This International Standard does not cover pricing, except for a requirement to provide information to customers. It is only applicable to billing for consumption-based utility network services and it applies to all bills or statements for utility network services where there is an ongoing account relationship between the customer and the supplier, regardless of the payment method used.
