Swiss KVG basic insurance covers identical treatments at every licensed provider — the only difference is the monthly premium. Written cancellation must arrive at your insurer by 30 November 2026 for a 1 January 2027 switch. Every provider must accept you without medical checks. August is the ideal time to prepare: gather your current policy details now so you can act the moment official 2027 premiums publish in late September.

Why Switching Each Year Is Worth One Hour of Your Time
Swiss KVG basic insurance is standardised by federal law under the Krankenversicherungsgesetz. Every licensed provider covers the same treatments, medications, and hospital stays in the same canton. The only legal difference between providers is the monthly premium — and that gap can be substantial.
Expats who enrolled with a provider on arrival and never reviewed their choice typically overpay by 20–35% for identical coverage. Premium rankings reset every October when the BAG publishes approved rates: a provider that was competitive in 2023 may rank poorly for 2027. There is no loyalty reward for staying. The switch itself takes roughly one hour.
The monthly savings from switching often fund meaningful contributions toward long-term financial security. The Swiss three-pillar pension guide explains how those savings fit into a broader plan, and the 2026 Swiss expat tax guide covers the deductions you can claim on Pillar 3a contributions. For the premium numbers themselves — filtered by your canton, age, deductible, and model — Expat-Savvy.ch is the most comprehensive English-language source, updated each October.
The August–November 2026 Window: What to Do Right Now
If you are reading this in August or September 2026, you have roughly three months until the 30 November deadline — and the most useful thing you can do today costs nothing: locate your current policy documents. Note your insurer name, policy number, deductible level (franchise), and insurance model (Standard, Hausarzt, HMO, or Telmed). Having those details on hand means you can act immediately when official 2027 premiums publish.
- August (now): Gather current policy details. Note your deductible and model. Decide whether you want to consider a model change.
- Late September: BAG publishes 2027 approved premiums. Run a comparison immediately — platforms slow under demand in October.
- October: Your insurer sends its 2027 premium notice. Compare your new rate against at least three alternatives in your canton.
- By 21 November: Post your cancellation letter by registered mail if switching. Seven business days before 30 November is the latest safe posting date.
- 30 November: Hard deadline. Written notice must physically arrive at your insurer — postmark alone is not sufficient.
Families relocating to Switzerland mid-year can still enrol immediately outside this window — see how immigration permits work in Switzerland for the full registration timeline, including the 90-day KVG enrolment rule for new arrivals.
2026 Deadlines at a Glance
The Swiss health insurance calendar is fixed by law. Miss 30 November and you remain with your current provider for the full 2027 calendar year.
| Date | Event | Your Action |
|---|---|---|
| Late September 2026 | BAG publishes approved 2027 premiums | Begin comparing — do not wait for your insurer's letter |
| October 2026 | Your insurer sends the 2027 premium notice | Compare your rate against at least three alternatives in your canton |
| 21 November 2026 | Recommended latest mailing date | Post cancellation letter by registered mail — 7+ business days to arrival |
| 30 November 2026 | Cancellation deadline | Written notice must have physically arrived at your insurer — not postmarked, arrived |
| 1 January 2027 | New coverage begins | Collect written confirmation from both old and new insurer |
| 31 March 2027 | Deductible increase deadline | Apply to raise your franchise effective 1 July 2027, if desired |
The 30 November deadline means arrival, not postmark. A letter posted 28 November via standard mail in a rural area can arrive 1 December — making your switch void for the year. Send by registered mail (Einschreiben / recommandé) at least seven business days before the deadline.
KVG Basic Insurance vs. VVG Supplementary: Two Different Products
Switzerland divides health cover into two legally separate layers. The switching rules differ fundamentally — confusing the two is among the most expensive mistakes expats make.
| KVG (Basic / Obligatory) | VVG (Supplementary) | |
|---|---|---|
| Required? | Yes — mandatory within 90 days of registration | Optional |
| Acceptance | Every licensed insurer must accept all applicants | Insurer may reject based on health history |
| Coverage | Federal catalogue — identical at every provider | Varies: dental, private hospital rooms, global cover |
| Annual deadline | Cancellation must arrive by 30 November | No standard deadline — check your individual contract |
| Safe switching order | Apply to new insurer, then cancel current | Get written acceptance from new insurer first, then cancel |
For KVG, acceptance is guaranteed by law — you can cancel first and apply second without any risk. For VVG supplementary cover, the order reverses entirely: secure written acceptance from the replacement provider before cancelling, because a VVG insurer can refuse based on medical history. Cancelling supplementary insurance without a confirmed replacement in writing is irreversible.
Your Two Biggest Premium Levers: Deductible and Insurance Model
Provider choice affects your premium — but two structural decisions inside KVG often create larger savings than a provider switch alone.
Annual Deductible (Franchise)
The franchise is what you pay out-of-pocket each calendar year before insurance covers 90% of costs. A 10% co-payment (Selbstbehalt) applies above the deductible, capped at CHF 700 per adult per year. Available levels run from CHF 300 to CHF 2,500 in six steps (300, 500, 1,000, 1,500, 2,000, 2,500).
A healthy adult in their 30s typically saves CHF 80–150 per month by choosing CHF 2,500 over CHF 300 — premium savings that usually exceed actual out-of-pocket healthcare costs in a normal year. Families with young children, or anyone managing a chronic condition, typically benefit from the CHF 300 deductible. You may raise your deductible mid-year by applying before 31 March, effective 1 July. Reducing the deductible mid-year is not permitted.
Insurance Model
All models cover the same federal medical catalogue. The difference is the access pathway — and the discount you receive for accepting a gated pathway to care.
- Standard: Free choice of any doctor or specialist. No premium discount. Maximum flexibility at the highest monthly cost.
- Hausarzt (GP gatekeeper): Register with a named family doctor; consult them first for non-emergencies. Typically saves 10–15% vs Standard.
- HMO (group practice): Use an approved group medical centre as your first point of contact. Typically saves 15–25% vs Standard; requires proximity to a participating practice.
- Telmed (telephone triage): Call an approved hotline before any non-emergency visit. Saves 10–20% vs Standard and suits expats who travel frequently.
Switching from a Standard CHF 300 plan to a Telmed or Hausarzt plan with a CHF 1,500–2,500 deductible is where the largest combined savings appear — sometimes 30–40% below the Standard premium. For current provider-specific figures by model and canton, Expat-Savvy.ch publishes updated comparison tables each October.
Step-by-Step: How to Switch Swiss Health Insurance
- Compare from late September. Official 2027 premiums publish in late September 2026. Filter by your canton, age, preferred deductible, and model. The federal priminfo.admin.ch tool is authoritative; for an English-language comparison with expat-specific context, Expat-Savvy.ch publishes the same data with canton-by-canton breakdowns.
- Apply to the new KVG provider. Acceptance is guaranteed by law. Completing an application typically takes 10–15 minutes online. You can apply before cancelling your current policy — there is no overlap risk with KVG.
- Cancel your current KVG by registered mail. Write to your current insurer with your full name, date of birth, policy number, and termination date of 31 December 2026. Post by registered mail at least seven business days before 30 November.
- Handle VVG supplementary separately, if applicable. Secure written acceptance from the new VVG provider before cancelling any existing supplementary cover.
- Collect written confirmation from both insurers. File the cancellation acknowledgement from the old insurer and the coverage confirmation from the new one — you may need both if a billing question arises during the transition.
If you are coordinating a broader relocation — housing, permits, banking — our relocation support service handles insurance transitions as part of the full setup. Reviewing your personal liability insurance at the same time keeps your annual review to a single October window. For long-term financial planning, a Pillar 3a account lets you redirect monthly premium savings into tax-deductible retirement contributions.
When You Can Switch Outside the November Window
Three situations allow a KVG change outside the annual deadline:
- Premium increase notification: When your insurer notifies you of a higher premium, you may cancel within 30 days of receiving that notice. Coverage ends when the increase was due to take effect.
- Moving to a new canton: KVG premiums are set per canton. Relocating within Switzerland triggers an immediate right to switch providers without waiting for November.
- Mid-year deductible adjustment: You may move to a higher franchise before 31 March, effective 1 July. Reducing the deductible mid-year is not possible.
New arrivals have 90 days from cantonal registration to enrol in KVG, with coverage backdated to the arrival date. Expats from the UK will find the system structurally different from the NHS; the UK-to-Switzerland relocation guide includes a full insurance enrolment checklist for first arrivals. The same is available for Americans in the USA-to-Switzerland guide.
Five Costly Mistakes to Avoid
- Never revisiting your original provider. Most expats enrol with the insurer their employer or HR recommended on arrival. Premium competitiveness resets every October. A provider inexpensive in 2022 may rank poorly for 2027.
- Comparing only the monthly premium. A low monthly premium with a CHF 300 deductible can cost more annually than a slightly higher premium with CHF 2,500 for a healthy adult. Always project total annual cost: 12 × monthly premium + expected out-of-pocket spending.
- Cancelling VVG before the replacement is confirmed. VVG insurers can reject applicants. Apply first, receive written acceptance, then cancel. Never cancel supplementary insurance without confirmed acceptance from the new provider in writing.
- Sending the cancellation letter too late. The 30 November deadline requires arrival, not postmark. Posting on 28 November via regular mail is not safe. Use registered mail with at minimum seven business days to spare.
- Staying on Standard model by default. Most expats remain on Standard simply because they never changed it. Switching to Telmed or Hausarzt alone — without changing provider — can save CHF 50–100 per month for a healthy adult with no regular specialist needs.

Frequently Asked Questions
What is the exact deadline to switch Swiss health insurance for 2027?
Your written cancellation must physically arrive at your current insurer by 30 November 2026. The switch takes effect 1 January 2027. Send by registered mail at least seven business days before the deadline — arrival, not postmark, is what the law requires.
When should I start comparing Swiss health insurance for 2027?
Start gathering your current policy details in August. Official 2027 premiums publish in late September 2026 — that gives you roughly six weeks to compare, apply to a new provider, and post your cancellation before the 30 November deadline. Waiting until October is possible but leaves little margin for the registered mail requirement.
Can a Swiss health insurer refuse to accept me when I switch?
Not for KVG basic insurance. Every licensed insurer must accept all applicants regardless of age, nationality, or medical history — no health questionnaire, no exclusions, no waiting periods. VVG supplementary insurers operate under separate rules and may decline applications based on health history.
Will there be a coverage gap when I switch insurers?
No. KVG coverage with your old provider ends 31 December 2026 and begins with the new provider 1 January 2027. There is no gap. The new insurer cannot impose waiting periods or exclude pre-existing conditions — the federal benefit catalogue applies from day one.
How much can I realistically save by switching health insurance in Switzerland?
Savings vary by canton, age, and your current plan. The largest combined reductions come from moving from a Standard model with a low deductible to a restricted model (Telmed or Hausarzt) with a higher deductible. In expensive premium cantons such as Zurich or Geneva, a healthy adult can save CHF 150–250 per month. For canton-specific figures, use the comparison at Expat-Savvy.ch.
