Moving home

As a property owner or tenant, you're responsible for water charges at your property. We rely on you to let us know if you use our water supply. This includes empty or vacant properties. You can find out who's responsible for paying water bills on our bill responsibility page.

Please keep us informed of any changes, such as moves and bereavements. This helps us make sure that our bills go to the right person.

Tell us about your move

You can tell us about your move as early as 28 days before your move date. If you're unsure who supplies your water, you can check this on the Water UK website.
