Online self service

Let us know you're moving

If you're a brand new customer to Welsh Water, or you're not currently a customer but you have been in the past, then you can use this service below to create an account.


If you're already a customer then you'll need to login or register to your online account in order to complete this process. If you'd prefer not to sign up then see how else you can contact us to let us know.

Information about how we work with credit reference agencies and how it could affect you is available here.

You can only let us know on or after the day you became responsible for the bill (the day you completed the purchase or tenancy agreement).

What you'll need:

  • Move date You can only let us know on or after the day of your move
  • Meter reading If known
  • Forwarding address We’ll need a forwarding address to send a final bill to. If you do not have a forwarding address, you will need to contact us.
