My Account About my bill Household Measured Charges

If your property is served by a meter, your bill is made up of two parts:

  • A service charge (charged per day based on the meter size).
  • What you have used (charged per cubic metre).*

*a cubic metre is 1000 litres or 220 gallons. This is the equivalent to 12 washes in a washing machine (full load), 12 baths or 28 standard showers (not a power shower).

When will you receive your bill?

  • You will receive a bill every six months (when we read the meters in your area).
  • We'll aim to bill on an actual reading. If we are unable to read the meter, we'll send an estimated bill.


What are your options if you receive an estimated bill?

  • Option 1 - You may take an actual reading (if it's safe to do so). Send us your reading using our submit a meter reading form. We will then send you an amended bill, or
  • Option 2 -Our estimating program is very accurate. You can just pay your estimated bill as normal. We'll aim to read the meter in the next six months.

Did you know...

  • If we need to change the meter for any reason, you will receive a bill between your six monthly bills.

When you move into a metered property:

  • You may not receive a bill for up to six months, if we read the meter just before you moved in, or
  • Your first bill could be for less than six months, if we read the meter shortly after you move in. So your first bill could be lower than your next six monthly bill.
  • When you move in, we'll send you a welcome pack so you know which months your bills are sent.
