How to cancel Origin Energy by mail
Gather your account details
Origin Energy will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Write your request
Ask Origin Energy to cancel the account, stop all further charges and confirm in writing. Postbye prepares the letter from our English template, with the subject line “Subject: Cancellation Request – [your name]”.
Send the letter by certified mail
Send it certified to Adelaide, Australia, copying the address from the next section letter for letter, and keep the receipt slip.
Keep proof the letter arrived
Delivery confirmation is your evidence that Origin Energy was asked. Watch the next statement or two for any further Origin Energy charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Origin Energy cancellation letter goes
For a letter to Origin Energy, use GPO Box 1199, 1199 Adelaide, Australia.
“GPO Box 1199” is a post-office box or mail-sorting line, so it takes post and not couriers: certified mail is the right way to reach it.
The letter is addressed “To Whom It May Concern,” and its details block uses the labels Account holder, Billing address on file and Email on file.

Before you cancel Origin Energy, check these
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
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
