How to cancel Fortum by mail
Find your account details
Fortum 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.
Write your request
Postbye drafts the request in Swedish, the language of Sweden, with “Ämne: Begäran om uppsägning – [your name]” as the subject line. It asks Fortum to close the subscription, stop billing and confirm in writing.
Mail the letter with a receipt
Take the letter to the post office and ask for certified delivery to 169 68 Solna. Keep the tracking number it gives you.
Hold on to the receipt
File the receipt with the letter. A Fortum charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Fortum cancellation letter goes
Fortum can be reached by post at Rättarvägen 3, 169 68 Solna, Sweden.
The postcode 169 68 belongs to Stockholms län, Sweden, so this is where the envelope is delivered.
The database also lists Askekroken 11, 0277 Oslo, Norway for Fortum. Use the first address above unless your agreement names this one.
Your name, address and email appear in a short block labelled Kontoinnehavare, Registrerad faktureringsadress and Registrerad e-postadress, under the greeting “Till berörd part,”.

Before you cancel Fortum, check these
- 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.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
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.
