The Most Common Swiss Insurance Mistakes
Swiss insurance is famously thorough — and famously easy to get wrong. Small administrative slips can cost hundreds or thousands of francs a year, while poor structural decisions can affect your family for a decade. After thousands of client reviews, the same mistakes come up again and again.
This guide brings together the most common Swiss insurance mistakes we see, why they happen, and exactly what to do instead.
Quick Summary
Most Swiss insurance mistakes fall into three categories: missed deadlines, poor product fit and lack of review. All three are easy to fix once you know what to look for.
Key Takeaways
- Missing the 30 November cancellation deadline locks you into another year with your current basic insurer.
- Choosing the highest deductible without checking your actual healthcare usage often costs more than it saves.
- Waiting until you are older or ill to add supplementary insurance leads to exclusions or refusal.
- Duplicate policies (e.g. travel cover through card and insurer) are one of the most common waste points.
- Not reviewing insurance every year means you drift into paying more for less.
1. Missing the 30 November Cancellation Deadline
Basic health insurance (KVG) can only be cancelled by written notice received by the insurer no later than 30 November. Miss the deadline and you are locked in for another year — even if a cheaper insurer offers identical benefits.
Fix: Send your cancellation by registered mail (Einschreiben) no later than mid-November. Only cancel after the new insurer has confirmed acceptance in writing.
2. Choosing the Wrong Deductible
The annual basic-insurance deductible (franchise) ranges from CHF 300 to CHF 2,500. Many people pick the highest to save on premiums, then pay more overall the moment they need treatment.
Fix: Estimate your annual medical spend. If it exceeds roughly CHF 2,000, a low deductible is usually cheaper. Young, healthy adults typically benefit from a higher deductible.
3. Waiting Too Long to Buy Supplementary Insurance
Supplementary insurance (VVG) requires medical underwriting. Waiting until a treatment is needed often leads to exclusions or refusal.
Fix: Sign up for supplementary modules while you are young and healthy — ideally in your twenties or in the first year after moving to Switzerland.
4. Forgetting to Insure a Newborn
Every newborn needs basic insurance within three months of birth. Registering the baby early also unlocks supplementary insurance subject to policy conditions, which is impossible to replicate later.
Fix: Enrol your baby before birth or in the first weeks of life to secure long-term supplementary cover.
5. Assuming Basic Insurance Covers Everything
Basic insurance does not cover glasses, most dental treatment, private hospital rooms, orthodontics or free choice of specialist. These gaps often become visible only when a bill arrives.
Fix: Map your household's likely healthcare needs and match them to specific supplementary modules — do not buy everything, and do not skip everything.
6. Paying for the Same Thing Twice
Duplicate cover is one of the biggest sources of waste. Common examples:
- Travel insurance through your credit card and supplementary health cover.
- Legal protection through your household policy and a standalone contract.
- Contents insurance covering items already insured under a specialist policy.
Fix: Once a year, list every insurance contract and compare what each covers.
7. Not Reviewing Insurance Annually
Swiss basic-insurance premiums change every autumn. Family situations change even faster. Rarely reviewing means paying more each year for a policy that no longer fits.
Fix: Book one review per year — ideally in October — before the cancellation deadline.
Mistake vs Best Practice
| Mistake | Better approach |
|---|---|
| Cancelling after 30 November | Cancel by registered mail in mid-November |
| Highest deductible by default | Match the deductible to expected medical spend |
| Adding supplementary cover late | Sign up while young and healthy |
| Insuring a newborn late | Register within the first weeks |
| Skipping annual review | One structured review each October |
Frequently Asked Questions
Can I change my basic insurer mid-year?
Only in specific cases, such as a premium increase notified by your insurer. Otherwise the next opportunity is the 30 November deadline.
Is a high deductible always worse for families?
Not always — but families with young children usually visit doctors frequently, which makes a lower deductible more cost-effective on average.
Can I still get supplementary insurance if I have a chronic condition?
Sometimes, but often with exclusions or a higher premium. It is significantly easier when you sign up in good health.
How do I check whether I have duplicate cover?
List every insurance contract and highlight overlapping benefits (travel, legal, contents, health). An independent advisor can review this quickly.
Your next step
Every mistake on this list can be avoided with a short annual review. If you would like an impartial, English-language check of your current policies before the 30 November deadline, our advisors offer a free consultation.
