How often will I receive my bill?
If you have a water meter - we aim to read this at least once a year and you should receive a bill twice a year.
If you don't have a meter - you'll receive an annual bill in either February or March telling you how much your water charges will be for the next year (1 April to 31 March).
When you move into a property you should receive your first bill within ten working days.
You'll be charged from the date you move in, until the end of March the following year.
