Where to send your Cloudflare cancellation letter

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

The addresses we hold

Everything we hold on where Cloudflare takes its post: the SE1 0NZ London delivery point for a cancellation letter, any second address, and how to send it so the delivery is on record.

Where the letter goesMailing address

CloudflareLavington Street 25SE1 0NZ LondonUnited Kingdom

The United Kingdom address on file for Cloudflare. Postal code SE1 0NZ.

How to address the envelope

  1. Use the address letter for letter

    The envelope reads Lavington Street 25, SE1 0NZ London, United Kingdom. Match the spacing and the box or street line exactly as printed.

  2. Add your return address

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

  3. Send it certified

    Take the letter to a post office counter and ask for certified mail: you get a postmarked receipt and a delivery record. Keep the tracking number and check it until it shows delivered.

  4. File the receipt with your copy

    Hold on to the letter copy, the receipt and the tracking page.

The letter, written out

The request itself is short: Cloudflare is asked to end the account, stop the charges and confirm in writing, with the account email, the domain or server name and the invoice number of the plan being cancelled where the brackets are.
