  • Using the private browser mode.
  • Using a different web browser or device.

Thank you for your patience.

Create a new Welsh Water billing account


If your previous property was in the Welsh Water region and you were the bill payer, please complete our moving within Welsh Water form.

You can only let us know on or after the day of your move.

HyperJar

HyperJar is perfect for planning and sharing the cost of your water bill with other people. Use HyperJar to set up Shared Jars to enjoy hassle-free group spending, including organising your bills, and create Jars for any product, service, or event you’re saving towards. Every Jar is a separate mini-account, and you can spend directly from any Jar with your HyperJar card. And don’t worry, sharing a Jar won’t affect your credit score – in fact, nothing you do in HyperJar will.
