How to cancel Spark Energy by mail
Note your account details
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Spark Energy can only act on a request it can match to an account.
Set out the request
The letter asks Spark 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.
Post it with proof of delivery
Use certified mail for the TD7 5EB Selkirk address in the next section, so the post office records the delivery. Write down the tracking number.
Keep the proof of delivery
The receipt dates your request. Look at your next statement for any Spark Energy charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Every address we hold for Spark Energy, with the envelope wording
Before you cancel Spark 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
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
