The plain-mail cancellation
Households send cancellations by ordinary post or email. The federal-law-binding format under Art. 7 KVG is registered post or insurer-portal-signed PDF. Without proper format, the cancellation may not bind.

How to change Swiss health insurance — annual cycle and extraordinary right.
Annual cancellation by 30 November under Art. 7 KVG, by registered post, with new-insurer acceptance secured first. Plus the extraordinary right under Art. 7 §2 KVG when the insurer changes contract terms. We say 'stay' more often than 'switch.'

In brief
Two federal mechanisms govern switching basic insurance. Annual cycle (Art. 7 KVG): notice received by the current insurer by 30 November, by registered post, with new-insurer acceptance signed before cancellation triggers. Effective 1 January of the following year. Extraordinary right (Art. 7 §2 KVG): 30-day window opens when the insurer notifies a premium increase, model change, or other contract amendment — independent of the November cycle. Format requirements are strict: registered post or insurer-portal-signed PDF; ordinary email and verbal phone confirmations don't bind. Supplementary insurance (VVG) is a separate decision — switching triggers fresh underwriting under Art. 4 VVG and conditions developed since signing become potential exclusions. We say 'stay' more often than 'switch' — most households recover more value from architecture restructuring than from changing insurer.
Switching — step by step.
-
Decide whether switching actually makes sense
Federal benefits are identical across all Swiss basic insurers under Art. 25 KVG. A switch saves money only if the new insurer's premium for your specific canton + age + Franchise + model is materially lower than your current. Run the comparison on primai.ch — annual saving below CHF 30/month per adult typically isn't worth the administrative friction.
Tip: If the saving is small (
-
Secure new-insurer acceptance first
Apply to the new insurer and receive signed acceptance before cancelling the old. If you cancel first and the new insurer rejects (rare on basic — Art. 4 KVG mandatory acceptance — but possible for supplementary), the cancellation can revert and leave you in a worse position. Standard sequence: apply → acceptance → cancel old.
-
Send the cancellation by registered post — by 30 November
Cancellation must reach the current insurer by 30 November, not be sent by 30 November. Use registered post with delivery confirmation. Some insurers accept signed PDF via their customer portal — verify your specific insurer's accepted format. Plain email or ordinary post may not bind under federal law.
Tip: Send by mid-November to avoid postal delays. Keep the registered-post receipt + the customer-portal confirmation as evidence.
-
Confirm cancellation in writing
The current insurer should send a written confirmation of cancellation effective 31 December. If no confirmation arrives within 2 weeks, follow up — the cancellation isn't complete until acknowledged. Keep all correspondence.
-
Use Art. 7 §2 KVG when premium notices arrive
If you missed November but received a premium increase notice, the extraordinary right of cancellation opens a 30-day window from receipt. Same registered-post format. The new-insurer acceptance still needs to be on hand first. The extraordinary right is most useful in October–December when annual premium notices arrive — many households think they've missed their chance and accept the increase unnecessarily.
-
Don't touch supplementary unless you have to
Switching basic insurance doesn't require switching supplementary — they're separate contracts under different statutes. Supplementary switching triggers fresh underwriting under Art. 4 VVG, and conditions developed since the original signing become potential exclusions. The clean basic-only switch is usually the right move; touching supplementary on the same cycle creates risk that the supplementary saving doesn't justify.
What we catch every week.
Trap 02
The cancel-first sequence
Households cancel the old insurer before receiving new-insurer acceptance. If something goes wrong with the new application, the cancellation can revert or leave them exposed.
Trap 03
The missed extraordinary right
Premium notices arrive in October. The 30-day extraordinary cancellation window under Art. 7 §2 KVG opens then — separate from November. Households who missed November can still switch via this lever.
Trap 04
The supplementary collateral damage
Households switch basic and supplementary on the same cycle. Supplementary fresh underwriting catches conditions developed since the original signing. The supplementary saving rarely justifies the underwriting risk.
Canonical four-traps reference: the four traps deep-dive.
A real-pattern case.
Anonymised pattern
An expat household in Basel received a +6.2% premium notice in October. The household had three open supplementary contracts (semi-private hospital, outpatient, daily-allowance) all 6+ years old. Comparis suggested switching to a cheaper basic insurer for ~CHF 35/month per adult saving. Our review: switch basic only via Art. 7 §2 extraordinary right; keep all three supplementary contracts with the existing insurer. Annual basic-side saving: ~CHF 840/household. Risk avoided: switching the 6+-year-old hospital semi-private would have triggered fresh Art. 4 VVG underwriting on a knee surgery the household had since signing — possible exclusion. The basic-only switch captures the saving; the supplementary stays clean.

Beyond this guide — the 45-minute review.
The 45-minute review with Robert reads your existing supplementary contracts before any switch decision, calculates the basic-only switch math, drafts the registered-post cancellation correctly, and verifies the new-insurer acceptance before the cancellation triggers. We say 'stay' more often than the market suggests — most reviews end with us recommending architecture restructuring on the existing insurer, not a switch.

Common mistakes.
Cancelling by email
Federal-law format is registered post or insurer-portal-signed PDF. Email may not bind.
Cancelling before acceptance
Get new-insurer acceptance first; cancel second.
Switching supplementary alongside basic
Supplementary fresh underwriting catches conditions since signing. Keep supplementary unless restructure is genuinely better.
Missing Art. 7 §2 KVG
Premium notice triggers a 30-day window. Households think they've missed November and accept the increase unnecessarily.
Confusing 'sent' with 'received'
Cancellation must reach the insurer by 30 November, not be sent by then. Send mid-November to leave postal margin.

Frequently asked — change swiss health insurance.
01 When can I switch Swiss health insurance?
Annual cycle: cancel by 30 November (Art. 7 KVG), effective 1 January. Extraordinary right: 30-day window when insurer notifies premium increase or contract change (Art. 7 §2 KVG). Plus specific events (move out of Switzerland, etc.) under separate provisions.
02 Do I need to send a registered letter to switch?
Yes for federal-law-binding cancellation, though some insurers accept signed PDF via customer portal as equivalent. Plain email or ordinary post may not bind. Verify your specific insurer's accepted format.
03 What is the extraordinary right of cancellation?
Article 7 §2 KVG gives a 30-day cancellation window when your insurer notifies a premium increase, model change, or contract amendment — independent of the 30 November annual cycle. Useful for households who missed November but received a premium hike.
04 Do I have to switch supplementary insurance when I switch basic?
No. Basic and supplementary are separate contracts under different statutes (KVG vs VVG). You can switch basic and keep supplementary with the existing insurer indefinitely. Most households should — switching supplementary triggers fresh Art. 4 VVG underwriting.
05 What happens if I miss the 30 November deadline?
You stay with your current insurer for the next calendar year — unless you receive a premium-increase notice, which triggers the 30-day extraordinary right under Art. 7 §2 KVG. Otherwise, the next switching opportunity is the following 30 November.
06 Can I switch insurer mid-year?
Generally no on basic — only via Art. 7 §2 KVG extraordinary right or specific events (move from Switzerland, becoming self-employed for 3a, etc.). Annual switching follows the November cycle.
07 Will my new insurer reject me on basic?
No — Art. 4 KVG mandates acceptance for every Swiss resident regardless of nationality, age, or health history on basic insurance. Rejection only applies to supplementary (VVG) where individual underwriting governs.
08 How long does the switching process take?
From cancellation send-date to effective new policy: 4–8 weeks. Send cancellation mid-November (10-15 working days postal margin); new policy active 1 January. Coverage continuity is automatic if both contracts are properly executed.
Switching, read properly.
