How to cancel So Energy by mail
Collect the details you need
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at So Energy is the easiest one to set aside.
Put the request in writing
State plainly that you want the So Energy account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Cancellation Request – [your name]”).
Send it by certified mail
Take the letter to the post office and ask for certified delivery to W4 5PY London. Keep the tracking number it gives you.
File the delivery record
It shows the date So Energy received your letter. Check your next statement: no So Energy charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your So Energy cancellation letter goes
So Energy lists 114 Power Road, Studio 2, W4 5PY London, United Kingdom as its mailing address.
The envelope is going to London, United Kingdom, so the postcode W4 5PY 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,”.

Before you cancel So Energy, check these
- Use the same name and email as on the account. A mismatch can delay the request.
- 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.
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.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
