How to change your Swiss health insurance
The deadlines, the right order of operations, and the traps that cost people a year.
Switching basic insurance in Switzerland is genuinely simple once you know the sequence. Almost everything that goes wrong comes down to doing the steps in the wrong order — or missing a date by a day.
The steps
-
Work out which deadline applies to you
Most people on a standard model give notice so that it arrives by 30 November, with the change taking effect on 1 January. If you moved to Switzerland recently, a different rule applies: you have three months from the start of your residence, and your cover is backdated to your arrival date.
Tip: Deadlines are about arrival, not postmark. Send registered post and keep the receipt.
-
Decide on the model and deductible first
Before comparing prices, settle two things: how much freedom you want in choosing a doctor, and how much you are willing to pay out of pocket each year. These two choices move the premium far more than the choice of insurer does.
Tip: Decide the deductible on your expected care needs, not on the premium table.
-
Compare on your own address
Premiums are set per canton and region, so national averages tell you very little. Get quotes for your actual postcode, your household composition, and the model you would genuinely use day to day.
-
Apply to the new insurer and wait for written acceptance
Submit the application and wait for confirmation in writing. For basic insurance every insurer must accept you, but you still want the confirmation in hand before anything else happens.
Tip: Keep the acceptance letter — it is what you rely on if the cancellation is queried later.
-
Only now cancel the old policy
With acceptance confirmed, send your cancellation to the previous insurer so it arrives before the deadline. State clearly that it applies to basic insurance only, unless you have deliberately decided to move supplementary cover as well.
-
Check the first statement
When the new year starts, confirm that the model, the deductible and the household members on your policy all match what you applied for. Errors are easiest to correct in the first weeks.
The traps to avoid
Trap 01
Cancelling before you are accepted
For basic insurance this is usually recoverable. For supplementary cover it is not: the new insurer can decline you, and by then your old policy is gone.
Trap 02
Treating basic and supplementary as one decision
They are governed by different laws, have different notice periods, and one is guaranteed to accept you while the other is not. Move them separately and deliberately.
Trap 03
Choosing a model you will not actually use
A discount for calling a hotline first is only a discount if you are willing to call the hotline first. Pick the model that matches how your household really behaves.
Trap 04
Assuming the deadline is the postmark
What counts is when the notice arrives, not when you sent it. A letter posted on 29 November can easily miss the deadline.
A worked example
A two-adult household that moved cantons in July
They assumed the move reset their insurance and let the November deadline pass. Their basic insurance stayed with the old insurer, still priced for their previous region — which happened to be one of the more expensive ones.
The outcome
They kept the policy for one more year, then switched with the deadline diarised. The lesson was not about which insurer to choose, but about which date to watch.
Common mistakes
- Comparing national average premiums instead of quotes for your own postcode.
- Cancelling supplementary insurance in the same letter as basic insurance.
- Choosing the lowest deductible out of caution when no regular treatment is expected.
- Waiting until late November, when insurers are at their busiest.

Frequently asked
Can I change my health insurance at any time?
Basic insurance normally changes once a year, effective 1 January. Certain events — such as a premium increase or a recent move to Switzerland — can open a shorter window.
Can an insurer refuse me?
Not for basic insurance: every insurer must accept every applicant. Supplementary insurance is different and involves health questions.
Do I have to cancel my old policy myself?
Yes. Applying to a new insurer does not cancel the old contract — the cancellation is a separate step, and it is the one people most often forget.
What happens if I miss the deadline?
Your existing policy continues for another calendar year. It is not a disaster, but it is worth diarising the date so it does not repeat.
Not sure which step applies to you?
The right sequence depends on your canton, your household, and whether supplementary cover is involved. A short conversation is usually faster than reading another comparison table.
