The expensive insurance mistake in Switzerland is not always being uninsured. It can be paying for the same risk twice, buying voluntary cover before understanding compulsory protection, or signing a long policy because a salesperson presented the monthly premium rather than the total commitment.
Insurance is useful when it transfers a loss your household could not comfortably absorb. It becomes poor value when the event is already covered, the exclusions remove the risk you care about, or the policy mixes protection and long-term saving without making the costs easy to compare.
This is a framework for reviewing cover, not personal insurance advice. Policy wording and household circumstances decide whether a product is appropriate.
Trap 1: treating basic and supplementary health insurance as one bundle
Compulsory basic health insurance and voluntary supplementary cover operate under different rules. The Federal Office of Public Health states that every authorised basic insurer must provide the same legally defined scope of basic benefits and treat insured people equally. You can therefore compare basic plans primarily on premium, model, service and practical access rules.
Supplementary insurance can cover extras such as private or semi-private hospital accommodation, some preventive checks, complementary treatment or routine dental care. It may use health questions, impose restrictions or refuse an applicant.
The trap is signing both as if they must stay with one company. Start with two separate questions:
- Which basic-insurance model and deductible fit my likely healthcare use and cash reserve?
- Which specific additional service do I want, and what would it cost to self-fund?
Do not cancel existing supplementary cover until a replacement has accepted you in writing. An application is not guaranteed approval.
Trap 2: excluding accident cover from the wrong policy, or paying for it twice
Employees who work at least eight hours per week for the same employer are generally covered for non-occupational accidents through their employer’s accident insurance. The official ch.ch guidance therefore identifies removal of accident cover from compulsory health insurance as a possible premium saving for eligible employees.
That does not mean accident risk disappears. It means the payer and policy change. If working hours drop, employment ends or self-employment begins, check immediately who covers non-occupational accidents. A premium saving is only valid while the other cover applies.
Trap 3: accepting a cold call as a neutral comparison
FINMA distinguishes tied intermediaries, who work in insurers’ interests, from untied intermediaries subject to direct registration and supervision. Untied intermediaries must appear in FINMA’s public register. Ask the person to state in writing:
- whether they are tied or untied;
- which insurers they can compare;
- how they are paid;
- their FINMA registration details where registration is required;
- the total term and cancellation date of every proposed contract.
FINMA reported in June 2026 that it continued to see unauthorised activity, pressure, unrealistic return promises and unsuitable life-insurance sales without transparent cost information. It also provides a form for reporting unsolicited calls connected with supplementary health insurance.
A registered intermediary is not automatically right for your needs. Registration is a verification step, not an endorsement of a recommendation.
Trap 4: buying life insurance as a savings plan without separating the two jobs
A combined life-insurance and savings product may be suitable in a specific estate, family or business-planning case. The problem is comparing it only with "doing nothing".
Separate the proposal into:
- the death or disability benefit;
- the savings or investment contribution;
- guaranteed and non-guaranteed values;
- acquisition, administration, risk and investment costs;
- surrender value after years 1, 3, 5 and 10;
- consequences of leaving Switzerland, losing income or stopping payments.
Then compare the protection element with standalone term cover and the savings element with a separate Pillar 3a or other suitable account. Do not assume separate products are always cheaper. Demand numbers that make the alternatives comparable.
A simple stress test
Imagine a combined policy requires CHF 300 per month for ten years. The headline commitment is CHF 36,000 before considering returns, tax treatment, fees or surrender penalties. Ask what happens if payments must stop after 24 months, when CHF 7,200 has been contributed. The written surrender value matters far more than an illustration based on completing the full term.
Trap 5: duplicating liability, travel, legal or purchase protection
Duplicate cover usually appears across products rather than through two identical policies. Examples can include:
- travel cancellation in a travel policy and a payment card;
- roadside or travel assistance through a car policy, motoring organisation and premium card;
- legal expenses in standalone, motor and union or professional-association benefits;
- accidental damage or theft protection in household cover and a retailer add-on;
- mobile-phone cover through household insurance, a telecom bundle and a card benefit.
Make a one-page risk register. For each policy, record the insured event, limit, deductible, geographic scope, named people and exclusions. Similar labels do not prove duplication, but they reveal where to compare wording.
If two policies cover the same event, do not assume two full payouts. Ask both insurers how coordination works and which policy responds first.
Trap 6: insuring losses your emergency fund can absorb
Insurance has administrative costs, expected claims and profit built into the premium. For small losses, repeatedly buying cover can cost more than retaining the risk.
Use three tests:
- Severity: would the loss threaten housing, debt repayment or long-term finances?
- Frequency: is it likely enough that a specialist product has genuine value?
- Self-insurance: can a dedicated cash reserve replace the item without borrowing?
A CHF 100 deductible on cover for a CHF 500 device changes the maximum useful payout to CHF 400 before exclusions and depreciation. If the annual premium is CHF 120, three claim-free years cost CHF 360. That does not automatically make the policy bad, but it turns a vague feeling of safety into a measurable decision.
Personal liability is a different type of risk. A serious third-party claim may be far beyond an ordinary emergency fund, and landlords commonly ask tenants for evidence of cover. Compare limits and exclusions, not just the premium.
Trap 7: ignoring contract duration and the cancellation window
The relevant price is the cost until the earliest realistic exit, not the monthly debit. Before signing, write these details at the top of the offer:
- start and end date;
- automatic-renewal rule;
- ordinary notice deadline;
- special termination rights after a claim, premium change or move;
- method and address required for cancellation;
- whether a household move changes rather than ends the policy.
Keep proof that cancellation arrived on time. Do not rely on a verbal instruction to an intermediary when the contract requires notice to the insurer.
Trap 8: cancelling useful cover before the replacement is secure
Shopping around is sensible, but sequencing matters. This is particularly important for supplementary health and life insurance, where a new provider may ask health questions or decline cover.
The safe order is:
- Apply for the replacement and disclose accurately.
- Receive written acceptance, including exclusions and start date.
- Check that the old policy can be cancelled on the intended date.
- Send valid notice and retain evidence.
With compulsory basic health insurance, use the official deadlines and confirm that the new insurer completes the transfer. Do not apply supplementary-insurance rules to the basic policy, or vice versa.
Trap 9: using the premium as the only comparison
Two policies with the same annual price can produce different outcomes because of:
- deductibles and co-payments;
- per-event and annual limits;
- replacement value versus current value;
- waiting periods;
- geographic restrictions;
- excluded activities or occupations;
- household-member definitions;
- claims-service requirements.
Create one scenario that matters to you and ask each insurer to show how the policy would respond. For legal protection, this might be an employment dispute that began before the policy started. For household cover, it could be a bicycle stolen away from home. The answer exposes waiting periods and location limits that a premium table misses.
A one-hour annual insurance audit
Once a year, collect every premium notice and policy schedule. Add the annual premiums, then group policies by the loss they cover. Mark any overlap and every product you could not explain in one sentence.
For each marked item, ask:
- What exact event triggers payment?
- What is the largest plausible payout after the deductible?
- What important exclusions apply?
- Do employment, a card, membership or another policy already cover it?
- What is the next cancellation deadline?
- Has the household changed since purchase?
Reviewing before renewal is more useful than reacting after the notice window closes. Put deadlines in the calendar with enough time to request comparable written offers.
When professional advice earns its cost
Independent, clearly paid advice can be valuable where a household has dependants, a mortgage, cross-border assets, self-employment, a company or substantial disability-income exposure. Ask the adviser to document scope, conflicts and compensation. Verify regulatory status through official registers rather than a badge on a sales page.
For a dispute, FINMA explains that it supervises institutions but does not decide private-law claims for a customer. The relevant insurance ombudsman, legal advice or court process may be the appropriate path depending on the issue.
The goal is not to own the fewest policies. It is to know what each one does, what it excludes and why its annual cost is worth transferring that particular risk.
