Trap 01
The cancel-first sequence

In brief
Switching basic-insurance providers follows Art. 7 KVG. Annual cycle: cancellation reaches current insurer by 30 November via registered post; new-insurer acceptance signed before cancellation triggers; effective 1 January. Extraordinary right: 30-day window when current insurer notifies premium increase or contract change (Art. 7 §2 KVG). Sequence matters: apply to new insurer → receive signed acceptance → cancel old by registered post. Reverse the sequence and a rejected application can leave the household without coverage. Don't switch supplementary on the same cycle unless the supplementary architecture genuinely needs restructuring — fresh underwriting under Art. 4 VVG catches conditions developed since signing. Most reviews end with basic-only switch + supplementary stays put.
Switching providers — step by step.
-
Decide whether the switch is worth doing
Federal benefits identical (Art. 25 KVG). The switch saves money only if the new insurer's premium for your specific case is materially lower — typically a CHF 25–50/month saving threshold to justify administrative friction. Architecture restructuring at existing insurer often beats switching: change Franchise tier, change model, claim missed IPV, etc. Run the comparison before committing.
-
Apply to the new insurer first
Submit application + cantonal Anmeldebestätigung + permit copy + bank details. Wait for written acceptance before cancelling the old insurer. Mandatory acceptance under Art. 4 KVG applies on basic — but sequence still matters; if anything goes wrong, you don't want to be uninsured.
-
Cancel old insurer by registered post — by 30 November
Cancellation must reach the current insurer by 30 November, not be sent by then. Use registered post with delivery confirmation. Some insurers accept signed PDF via customer portal — verify your specific insurer's accepted format. Plain email or ordinary post may not bind under Swiss insurance law.
Tip: Send by mid-November to leave 10–15 working days postal margin. Keep the registered-post receipt.
-
Confirm cancellation in writing
Current insurer should send written confirmation of cancellation effective 31 December. If no confirmation arrives within 2 weeks, follow up. The cancellation isn't complete until acknowledged. Save all correspondence.
-
Verify coverage transition on 1 January
New insurer's coverage should activate 1 January with no gap. Verify: insurance card arrives before 1 January; premium debit set up correctly; supplementary (if you transferred any) shows the right contracts. Most issues are administrative; flag immediately if anything looks wrong.
-
Don't touch supplementary
Supplementary contracts under VVG are independent of basic. Switching basic insurer doesn't require switching supplementary. Keep existing supplementary at the old insurer. Switching supplementary on the same cycle triggers fresh Art. 4 VVG underwriting and conditions developed since signing become potential exclusions. The supplementary saving rarely justifies the underwriting risk.
-
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 mechanics + new-insurer acceptance first. Most useful in October–December when annual premium notices arrive.

Trap 02
The plain-mail cancellation
Email or ordinary post may not bind under federal law. Registered post or insurer-portal-signed PDF only.
Trap 03
The supplementary-on-same-cycle
Switching supplementary triggers fresh Art. 4 VVG underwriting. Most households save more by leaving supplementary alone.
Trap 04
The missed Art. 7 §2 lever
Premium notices in October open a 30-day extraordinary right separate from November. Many households accept the increase unnecessarily.
Canonical four-traps reference: the four traps deep-dive.
A real-pattern case.
Anonymised pattern
An expat household in Lausanne received a +6.5% premium increase in October. Comparis suggested switching basic insurer for ~CHF 35/month per adult saving. Three supplementary contracts (semi-private, outpatient, accident daily-allowance) all 4+ years old. Our review: basic-only switch via Art. 7 §2 KVG extraordinary right, supplementary stays. Application submitted to the new insurer first; signed acceptance received within 8 days; old insurer cancellation sent by registered post within the 30-day extraordinary-right window. Effective 1 January. Annual basic-side saving: ~CHF 840/household. Supplementary risk avoided — switching on the same cycle would have re-underwritten a knee surgery from year 3.

Beyond this guide — the 45-minute review.
The 45-minute review with Robert drafts the registered-post cancellation correctly, secures new-insurer acceptance before cancellation triggers, verifies the basic-only switch math against your supplementary architecture, and applies Art. 7 §2 KVG extraordinary right when premium notices arrive. We say 'stay' more often than 'switch' — restraint is the advisor difference.

Frequently asked — switch insurance providers.
01 How do I switch Swiss health insurance providers?
Apply to new insurer → receive signed acceptance → cancel old by registered post (received by 30 November under Art. 7 KVG) → effective 1 January. Plus Art. 7 §2 KVG extraordinary right opens a 30-day window when current insurer notifies a premium increase.
02 Can I cancel by email?
Generally no — federal-law-binding cancellation under Art. 7 KVG is registered post (or insurer-portal-signed PDF where the insurer accepts that format). Plain email or ordinary post may not bind.
03 When can I switch Swiss insurance providers?
Annual: by 30 November for next-year-effective. Extraordinary: 30-day window from premium increase notice (Art. 7 §2 KVG). Specific events (move out of canton if insurer doesn't operate there, leaving Switzerland) trigger separate provisions.
04 Do I have to switch supplementary insurance when I switch basic?
No. Basic and supplementary are separate contracts. You can switch basic and keep supplementary at the existing insurer. Switching supplementary triggers fresh Art. 4 VVG underwriting — usually not worth the saving.
05 Will my new insurer reject me?
Not on basic — Art. 4 KVG mandates acceptance for every Swiss resident regardless of nationality, age, or health history. Rejection only applies to supplementary (VVG) where individual underwriting governs.
06 What happens if I cancel and the new insurer rejects?
On basic, rejection is impossible (Art. 4 KVG). On supplementary, rejection means you've cancelled supplementary cover with no replacement. Always secure new-insurer acceptance before cancelling.
07 How long does the switch take?
From cancellation send-date to new policy active: 4–8 weeks. Send mid-November (postal margin); new policy active 1 January. Coverage continuity is automatic if both contracts are properly executed.
08 Can I switch insurer mid-year?
Generally no on basic — only via Art. 7 §2 KVG extraordinary right or specific events (move from Switzerland, etc.). Annual switching follows the November cycle.
Provider switch, read properly.
