How to cancel Symbio Energy by mail
Gather your account details
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Symbio Energy can only act on a request it can match to an account.
Prepare the letter
Postbye turns the request into a finished English letter headed “Subject: Cancellation Request – [your name]”: close the Symbio Energy account, stop every charge and reply in writing.
Post the letter
Take the letter to the post office and ask for certified delivery to CR0 0XT Croydon. Keep the tracking number it gives you.
Keep the proof of delivery
It shows the date Symbio Energy received your letter. Check your next statement: no Symbio Energy charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Symbio Energy cancellation letter goes
Symbio Energy takes its post at 12 - 16 Addiscombe Road, 1st floor, CR0 0XT Croydon, United Kingdom, which is where a cancellation letter belongs.
Copy the postal code CR0 0XT exactly: it is what routes the letter to Croydon, United Kingdom.
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,”.

Before you cancel Symbio 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
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.
