How to cancel One Fitness by mail
Get your account details together
One Fitness will look your account up from what the letter says, so check your membership number, the home club you joined at and the name on the membership agreement first.
Prepare the letter
One Fitness is based in Netherlands, so the letter goes out in Dutch, built from our Dutch template. Subject line: “Onderwerp: annuleringsverzoek – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Mail it with tracking
Send it certified to Hilversum, Netherlands, copying the address from the next section letter for letter, and keep the receipt slip.
Keep proof the letter arrived
Keep the tracking record with your copy of the letter. If One Fitness bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your One Fitness cancellation letter goes
One Fitness can be reached by post at Groest 100, 1211 EE Hilversum, Netherlands.
Hilversum is in Noord-Holland, Netherlands; the postal code to quote is 1211 EE.
The letter greets the reader with “Geachte heer/mevrouw,”; your own details sit under the labels Accounthouder, Factuuradres in dossier and E-mailadres in dossier.

Before you cancel One Fitness, check these
- Freezing or pausing a membership is not cancelling it. Say clearly that you want the membership ended.
- Read the notice window in your agreement. A letter that arrives after the cut-off can miss that month's charge.
- Annual fees and monthly dues are sometimes billed separately. Ask for both to be ended.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a gym or fitness membership
Gyms often require written notice, set a notice window before the next billing date and can tie the cancellation to the home club, so a dated letter is the record that counts.
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.
