Interest on unpaid amounts​

Amounts not paid in full may accrue interest daily from the bill's due date at the current interest rate. Until 30 June 2017, the interest rate is 6.1 per cent per year. This is set annually by the Essential Services Commission. 

We are charging interest on unpaid amount to encourage on time payment, which will mean we can direct our resources away from debt recovery and focus on what really matters. This is another way we're working smarter and implementing productivity improvements so we can deliver the best customer experience.
