Minimise your charges and spread out your payments if your business has been affected by Covid-19

To keep your charges as low as possible, remember to provide regular meter readings whenever you can.

Wholesale charges were able to be reduced for businesses that were closed due to Covid-19 between 16 March 2020 and 31 July 2020, provided we were notified of the temporary closure within 16 months of the period in question. No similar discount is available for businesses affected by later lockdowns or for customers who notify us of their closure in this period more than 16 months after the event.

You can submit your meter readings here or by using the button below. We'll add them to your account right away and ensure they are used when we calculate your next bill.

Reduced charges between 16 March and 31 July 2020

If you notified us before August 2021 of your temporary closure between March and July 2020, the permitted reduction in fixed charges should already have been applied to your account. This may have been applied as a standalone credit, or we may simply have excluded fixed charges from your bill for the period in question.

Remember, metered consumption will still be charged even if your business was closed. If you haven't already, please provide up-to-date meter readings so your reduced water usage can be reflected in your next bill.

Metered customers

If you have a water meter, the calculation of charges on your bill from the Central Market Operating System (CMOS) are based on your previous meter readings. This means charges are calculated for each month based on your average daily consumption.

Although you can reduce your water usage, your bills may not be reduced for several months if we don't have an up-to-date reading, depending on when we take our normal meter readings at your premises.

You can take two meter readings yourself, 1 month apart, and submit them to us (submit each reading on the day you take them). We will use your readings in your next bill to ensure you are charged accurately for the water recorded on the meter.

Unmetered customers - (Business Assessed)

If your bills are calculated on an assessed or unmeasured tariff and your consumption, hours, or number of employees has changed as a result of the Covid-19, we may be able to apply for a reassessment – in some cases this can significantly reduce bills.
