If you have had a concealed leak on your property that has caused a sudden increase in your bill, you may be eligible for a Concealed Leak Allowance.

The Concealed Leak Allowance:

  • refunds you 70% of the excess water usage charges that result from the leak. Read more below about how this is calculated. This percentage may vary by customer type (see below for more details).
  • can only be claimed once per property, per ownership.
  • comes in the form of a 'Leak Allowance' credit on your account.
  • can be applied to a maximum of 2 billing quarters (based on the last two billing periods of the leak, including the one in which the leak was repaired).

If you have a shared meter (e.g. you’re in a duplex or apartment), your rebate will be calculated just like your bills: as a percentage of your overall usage.

The Concealed Leak Allowance does not cover water loss from: 

  • leaking taps, toilet cisterns, hot-water systems or other water appliances 
  • faulty plumbing or human error resulting in the filling of a rainwater tank 
  • property sprinkler or other irrigation systems 
  • swimming pools, spas, ponds and other outdoor water features, or their related fittings.

We examine your billing history to calculate your daily average usage in the last 12 months prior to the leak.

We then look at the bill/s that recorded the leak to calculate the amount of excess water usage.

The allowance for excess water usage is 70% of the excess water usage charges and a 100% of the excess sewerage usage charges (if applicable). This is applied as a 'Leak Allowance' credit on your account.

FOR EXAMPLE

Normal water usage

$200

Now (with a concealed leak)

$600

$600 minus $200 =

$400

70% of $400 =

$280

Your Leak Allowance =

$280 plus excess
sewerage usage charges
(if applicable)

Small business customers using no more than 100 kL of water per annum may be eligible to receive the Concealed Leak Allowance.
