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.
New customers
If you’re moving into our area, tell us about your move by registering for an online account.
Moving within our area
Customers moving to another property can update their address in their online account.
Leaving our area
If you're leaving our area, you can close your account in your online account.
Moving out of a shared property
If you're moving out of a shared property and the account is in your name, please let us know you’re moving out. Someone still at the property will need to contact us to set up an account.
Landlords and multiple properties
Tell us about your tenants and properties by using Landlord Tap. If you have more than one property needing a Thames Water account, you can call us on 0800 980 8800 to set them up.
Help when someone's passed away
When someone has passed away, we can help close an account or move it into a different name. Find out how to notify us of a bereavement and what information we'll need.

Furnished properties and renovations under the cost of £100,000 must have an account. Your bill will be payable as normal.
If your property is unfurnished, please contact us on 0800 980 8800. For renovations over the cost of £100,000, contact us on 0800 009 3921.
