How to cancel Discover Energy by mail
Start with your account details
Have the name and email on the account and, if you have one, an account or customer number to hand. The details in the letter need to match what Discover Energy has on file.
Set out the request
The letter asks Discover Energy to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Cancellation Request – [your name]”. Postbye fills it in from our English template.
Mail it with tracking
Take the letter to the post office and ask for certified delivery to 3640 South Brisbane. Keep the tracking number it gives you.
Keep the proof of delivery
Delivery confirmation is your evidence that Discover Energy was asked. Watch the next statement or two for any further Discover Energy charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Discover Energy cancellation letter goes
For a letter to Discover Energy, use PO Box 3640, 3640 South Brisbane, Australia.
“PO Box 3640” 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.
Inside, the salutation reads “To Whom It May Concern,”, followed by your details under Account holder, Billing address on file and Email on file.

Every address we hold for Discover Energy, with the envelope wording
Before you cancel Discover Energy, check these
- 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.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
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
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
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.
