How to cancel Momentum Energy by mail
Get your account details together
Momentum 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.
Prepare the letter
Your Postbye letter to Momentum Energy asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Cancellation Request – [your name]”. It comes from our English template.
Post it with proof of delivery
Use certified mail for the 3000 Melbourne address in the next section, so the post office records the delivery. Write down the tracking number.
Hold on to the receipt
The receipt dates your request. Look at your next statement for any Momentum Energy charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Momentum Energy cancellation letter goes
Momentum Energy lists Flinders Lane 353, 3000 Melbourne, Australia as its mailing address.
The envelope is going to Melbourne in Victoria, Australia, so the postcode 3000 must be on the front.
Your name, address and email appear in a short block labelled Account holder, Billing address on file and Email on file, under the greeting “To Whom It May Concern,”.

Every address we hold for Momentum Energy, with the envelope wording
Before you cancel Momentum Energy, check these
- 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.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
