Here you'll find information on how we bill you for your water and sewerage service, and how you could lower the cost of your bill.
As a customer of Welsh Water, your bill will have charges for water and sewerage services. This is the cost of cleaning water and getting it to your taps, and for taking away waste water and cleaning it before it goes back into the environment.
If you have a water meter, you'll get a bill every six months for the water you use, worked out from the meter readings you give us.
If you don't have a water meter, you'll get a bill once a year with a cost based on your property.
