How does the pay on time discount work?

To be eligible for the pay on time discount, you need to ensure that you have made all of your monthly instalment payments on time too. Your actual usage for the quarter (assuming your meter is read) is known when you receive the quarterly bill. We calculate charges for the whole quarter based on this, and then deduct the pay-on-time discount (and payments you have made during the quarter). Discounts are calculated and applied before GST.
