Where to send your Thames Water cancellation letter

Read the addresses on this page next to the full guide to cancelling Thames Water.

The addresses we hold

One place for Thames Water's mailing addresses: the Reading delivery point for a cancellation letter first, then the rest of what the database holds, with envelope wording that matches.

Where the letter goesMailing address

Thames WaterVastern RoadRG1 8DB ReadingUnited Kingdom

The United Kingdom address on file for Thames Water. Postal code RG1 8DB.

How to address the envelope

  1. Copy it exactly onto the envelope

    The front of the envelope carries Vastern Road, RG1 8DB Reading, United Kingdom and nothing else in the address block. Check the RG1 8DB digit by digit before it goes in the post.

  2. Add the return address

    Top-left, your own name and address. A return address is what the post office needs to send the letter back if Thames Water has moved.

  3. Send it certified

    Certified mail is bought at the post office: hand the letter to a postal employee, keep the postmarked receipt, and follow the article number until the delivery shows.

  4. Keep what the post office gives you

    Keep your copy of the letter, the receipt and the delivery record in one place. The delivery date is the one to quote if the account is billed again.

The letter to send

A plain, dated letter to Thames Water asking for the cancellation, the end of every charge and written confirmation. Have the name and email on the account and, if you have one, an account or customer number to hand; our letter template fills the same shape in on screen.
