Terminating health insurance in Switzerland: using the deadlines properly (the ultimate switching guide)

Every autumn, Switzerland catches switching fever. When the premiums for the coming year are announced, hundreds of thousands of Swiss policyholders want to terminate their compulsory basic insurance and move to a cheaper health insurer.

Anyone searching for "terminating health insurance deadline 30 November", "changing basic insurance in Switzerland" or "supplementary insurance notice period" who wants to play it safe needs to know the unforgiving statutory deadlines of the Swiss Federal Health Insurance Act (KVG/LAMal) precisely. In the insurance world the legislator forgives no delay: one single day late and you stay tied to your existing insurer for another full year.

This comprehensive expert guide sets out the difference between basic and supplementary insurance in detail, explains the exact deadlines, warns about the typical pitfalls and gives you a legally sound template.

1. Basic insurance: the classic year-end deadline

Compulsory basic insurance (required by law for everyone resident in Switzerland) runs on an extremely rigid deadline regime.

The ordinary notice period (30 November)

The cut-off date: for basic insurance, the calendar year is in principle the insurance year. The ordinary notice period is three months. That means: your written termination must reach your current health insurer's letterbox by 30 November at the latest (the last working day in November, received by the insurer).
The catch in the receipt principle: as in tenancy law, what counts is receipt. Posting the letter on 30 November is absolutely not enough — it has to be physically with the insurer on that day. Sending it by registered post by mid-November at the latest is therefore strongly recommended.
The exception when you change your deductible: if you choose a different deductible (a different excess amount) or switch to a savings model (such as HMO or the family doctor model), the notice period is often exceptionally shortened to 31 December. In that case the termination must reach the insurer by 31 December at the latest (provided the insurer sent you the new premium overview in good time).

The second chance: terminating after a premium increase (mid-year switch)

If the health insurer announces a premium increase for the coming year in the autumn (usually at the end of October), a special right under the KVG applies:

If your insurer raises the premium, you have the right to an extraordinary termination as of 31 December.
The notice period is shortened in this case: the termination must reach the insurer by 30 November at the latest.
Important for the half-year option (basic model with a CHF 300 deductible): anyone on the ordinary deductible who has chosen the basic model with a CHF 300 deductible may in certain circumstances even terminate as of 30 June (with a three-month notice period, i.e. received by 31 March at the latest). Most policyholders, however, take the standard switch as of 1 January.

2. The big stumbling block: basic vs. supplementary insurance

A fatal mistake many consumers make when changing health insurer in Switzerland is treating basic and supplementary insurance as the same thing. Completely different rules apply here.

Different laws: while basic insurance falls under the strict KVG (Health Insurance Act) and must be offered by every insurer at legally uniform prices (for the same region and age group), supplementary insurance (dental cover, supplementary hospital cover, supplementary outpatient cover) falls under the Insurance Contract Act (VVG/LCA).
A longer notice period: supplementary insurance generally has a considerably longer notice period — usually three months before the end of the insurance year, and some contracts even require three or even six months to the end of the contract year (the contract year is often identical to the calendar year, but depending on the contract it can differ). Check the terms of your individual policy without fail.
The golden rule before terminating: never terminate your supplementary insurance in haste before you hold written confirmation of acceptance from a new insurer for that supplementary cover. Because supplementary insurers are allowed to reject an applicant or attach an exclusion (a health assessment!), you could otherwise end up with no supplementary cover at all.

3. Step by step: how to switch insurers smoothly

Anyone planning to change provider in the autumn should go about it strategically:

Compare premiums in October: as soon as the Federal Office of Public Health (FOPH) has approved the new premiums, at the end of September or in October, compare the offers on neutral portals (such as Priminfo.ch).
Request a new quote: complete the application for basic insurance (and optionally supplementary insurance) with your preferred new insurer. Wait for confirmation of the basic insurance without fail.
Draft the termination in good time: write the termination letter (see the template below) and sign it.
Send it by registered post: send the letter by registered mail to your old insurer with plenty of buffer (ideally by mid-November), so that you hold legally sound track-and-trace proof.
Wait for confirmation: the old insurer will send you a termination confirmation and tell you exactly where your account stands.

4. Legally sound template: terminating health insurance correctly

Use this professional template, adjust the square brackets and send it by registered post:

5. Summary and check-list for changing health insurer

Keep the cut-off date in view: the termination of basic insurance must have reached the insurer by 30 November at the latest.
Avoid formal errors: a termination letter by email is tolerated by many insurers, but a physically signed letter sent by registered post is always the legally safest route.
Check supplementary policies separately: watch for the longer VVG deadlines (often 3 months before the end of the year) and terminate them only once the new insurer has confirmed acceptance in writing.

With this solid expert grounding you will save a great deal on premiums next year and handle your change of health insurer in Switzerland completely stress-free and on sound legal footing.
