1. When is the deadline for changing health insurance in Switzerland?

Cancellation periods apply when changing health insurers. These periods differ for basic and supplemental insurance.

Changing health insurance: deadline for basic insurance

You can change your basic insurance every year. However, you must observe the cancellation period. 

These are the possible cancellation dates:

  • 30 November for a change on 1 January

  • 31 March for a change on 1 July, under certain conditions

The prerequisites for a cancellation date on 31 March are as follows:

  • You are insured in the standard model

  • You have the lowest deductible (300 francs for adults, 0 francs for children) 

Do you have the standard insurance model? Then, regardless of the deductible, you may also change the insurance model from the following month (Art. 100 para. 2 HIO). This is only applicable if you are changing policy with the same health insurer.

Our tip: set up a cancellation reminder for switching health insurance.

Calculate health insurance premiums

In rare cases, health insurers adjust premiums during the year. This is done at the request of the Federal Office of Public Health (FOPH). In this situation, you have a special right of cancellation. You can then change your health insurance during the year, regardless of the model.

If your health insurer adjusts its premiums during the year, it will notify you at least two months before the increase. You then have a cancellation period of one month (Art. 7 para. 2 HIA).

When can I change supplemental insurance?

The cancellation deadline for supplemental insurance can vary depending on the insurer and product. Health insurers often have a cancellation deadline of three months before the end of the year. This means that your notice of cancellation for supplemental insurance must reach your health insurer by 30 September.

Good to know: supplemental insurance policies often have a minimum term. You can cancel these policies at the earliest once this term has expired. However, if the minimum term is several years, you can terminate the contract after the third year at the latest (Art. 31a para. 1 IPA).

2. Cancelling health insurance in Switzerland: how do I comply with the cancellation period?

What’s important is the date on which the health insurer receives your cancellation letter. The postmark is irrelevant

Send your cancellation as a registered letter. This gives you legal proof of delivery. You should also ask for written confirmation of the cancellation.

What if the cancellation deadline is on the weekend?

In some years, 30 November falls on a weekend. In this case, your letter of cancellation must arrive by the last workday before 30 November. In 2025, this is 28 November.

3. How do I cancel my health insurance in Switzerland?

The process for cancelling your health insurance depends on the insurance product. Comparis offers a guide with just a few steps. 

Guide to changing basic health insurance

  1. Compare different health insurers, premiums, models and deductibles at an early stage.

  2. Request one or more quotes free of charge and with no obligation.

  3. Choose the best deal for you and take out your new basic insurance policy.

Cancel your existing basic insurance within the deadline by registered post. Your new basic insurance policy will take effect as of 1 January or 1 July. Comparis tip: use our health insurance cancellation template for cancelling both basic and supplemental insurance.

Important: in order for your current provider of basic insurance to close your insurance policy, it needs confirmation of acceptance from the new health insurer. This means that if the acceptance process with the new health insurer is delayed, you will still be insured with the old health insurer until you can provide confirmation of acceptance.

How to switch supplemental insurance

  1. Check the cancellation deadline of your existing health insurer. For most insurance providers, this is 30 September. 

  2. Compare the supplemental insurance policies of different health insurers. Also compare different products offered by a particular health insurer. The benefits and premiums can vary significantly.

  3. Request one or more quotes free of charge and with no obligation.

  4. Submit your insurance application and complete the health questionnaire for your chosen health insurance policy.

The new health insurer will send you a confirmation of acceptance. Only cancel your old supplemental insurance policy once you’ve received this confirmation. Otherwise, you may end up without any supplemental insurance at all. This is because health insurers may reject applications. Send the cancellation letter by registered mail.

4. Changing health insurance in Switzerland: FAQs

As a rule, you have to cancel your health insurance in writing. It’s best to send a registered letter. This way, you have proof that the cancellation letter has been received. The best way to do this is to use a cancellation template for your health insurance.

Some health insurers also accept cancellations by email or via their online portal. You will often have to scan or photograph the signed cancellation form. Check in good time whether you can cancel your health insurance online. If you cancel by email, always ask for written confirmation from the health insurer.

You can switch basic health insurance no more than twice a year. Everyone can switch with effect from 1 January. Changing with effect from 1 July is only possible for those insured under the standard model with the lowest deductible.

However, all policyholders in the standard model can change the health insurance model at the beginning of the next month – regardless of the deductible.

Yes, you can cancel and change your supplemental and basic insurance independently from each other. When cancelling, indicate which insurance you wish to cancel.

Good to know: the health insurer is not allowed to terminate your supplemental insurance if you cancel your basic insurance (Art. 7 para. 7 HIA).

Yes, you can. However, the new health insurer must inform your old health insurer of your admission. Only then will the policy switch be valid.

If this isn’t done by the end of the year, you’ll remain insured with your current health insurer until they receive this information.

No. You can’t change your health insurance until you have paid all outstanding payments in full (Art. 64a para. 6 HIA). The costs include:

  • Premiums

  • Out-of-pocket expenses

  • Default interest

  • Debt enforcement costs

This applies to debts with an outstanding reminder on 30 November (Art. 105l HIO).

Children’s debts

Parents may not change their children’s health insurance if reminders are outstanding for their children (Art. 64a para. 6 HIA). However, when a child comes of age, they will not be charged for the debts incurred before they came of age (Art. 105l para. 2 HIO).

This means that after their 18th birthday, the child can switch health insurer – even if the parents have not paid some bills.

It is compulsory to take out basic health insurance in Switzerland. You can change health insurance regardless of your state of health or age. Health insurers are obliged to accept you – even if you are undergoing treatment.

There are different rules for supplemental insurance. You often have to answer health questions to be accepted for these policies. The health insurer is not obligated to accept you. Only cancel your existing supplemental insurance once you’ve received confirmation that you’ve been accepted for your new insurance policy.

Do you want to cancel your basic insurance but keep your supplemental insurance with your current insurer? If so, you must communicate this clearly. The best way is to add a note to your cancellation letter that states: “This cancellation only applies to my basic insurance policy. My supplemental insurance will remain with your company.”

Good to know: the current health insurer may not cancel the supplemental insurance policy if you change your basic insurance (Art. 7 para. 7 HIA).

With some health insurers, you can cancel by email. However, your health insurer is not obligated to accept cancellations it receives by email. Check in good time whether your health insurer accepts cancellations by email.

To cancel by email, you usually need to scan the signed cancellation form. Cancellation is usually not possible without a signature. If you cancel by email, always ask for written confirmation from the health insurer.

The health insurer must notify you of their new premiums by 31 October at the latest. If they fail to do this, the cancellation deadline is extended. This is because, after receiving notice of the new premium, you have a cancellation period of one month (Art. 7 para. 2 HIA). They must inform you of your right to cancel in the letter.

There are several ways to save on health insurance premiums. For example, you can reduce your premiums by changing your deductible or insurance model.

  • Deductible: do you expect your healthcare costs not to exceed 2,000 francs in a year? Then the highest deductible of 2,500 francs is worthwhile. If you anticipate higher costs, the lowest deductible of 300 francs is worthwhile. Deductibles between the lowest and the highest are usually not worth it.

  • Insurance model: health insurers offer premium discounts for non-standard insurance models. Check the costs of the various models using the premium calculator.
