How to cancel Gasag Gas by mail
Gather your account details
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Gasag Gas names the right account the first time.
Prepare the letter
Postbye drafts the request in German, the language of Germany, with “Betreff: Kündigungsanfrage – [your name]” as the subject line. It asks Gasag Gas to close the subscription, stop billing and confirm in writing.
Send the letter by certified mail
Send the letter to the Berlin mailing address shown below by certified mail. Keep the tracking number safe.
File the delivery record
Keep the tracking record with your copy of the letter. If Gasag Gas bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Gasag Gas cancellation letter goes
Gasag Gas takes its post at Henriette-Herz-Platz 4, 10178 Berlin, Germany, which is where a cancellation letter belongs.
Copy the postal code 10178 exactly: it is what routes the letter to Berlin, Germany.
Your name, address and email appear in a short block labelled Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse, under the greeting “Sehr geehrte Damen und Herren,”.

Before you cancel Gasag Gas, check these
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
Start on gasag.de: the account area there shows who actually bills you, which decides who the request must reach.
