Calculating water rates
All invoices are calculated on the number of days in each invoice period, and water used is charged for at a:
- volumetric rate (per cubic metre (1000 litres))
- fixed annual charge per separately used or inhabited part of a rating unit.
See the current years Rates Setting paper Rates for 2023/24 for information about what the current rates are, and How rates work for more about our rating system.
There is no 'free' allowance of water in the annual fixed charge, and the fixed charge applies to each separately used part of a rating unit (ie, a home and a granny flat).
You can estimate your own water use – see Estimating your water costs.
