Switching health insurer is one of the few genuinely free ways to cut a fixed cost in Switzerland – but “cheapest health insurance” is not a single product or a single company. Basic insurance (called LAMal in French, KVG in German, and formally the “obligatorische Krankenpflegeversicherung”) covers exactly the same legally-defined benefits no matter which insurer you pick. What changes is the price, and that price depends on where you live, how old you are, which deductible you choose, and which insurance model you sign up for – never on your income or your health.
Why “cheapest” depends on your postcode, not the insurer’s name
Under Swiss law, every basic insurance policy from every insurer must cover the same catalogue of medical treatments. Insurers cannot refuse you, cannot charge you more because of a pre-existing condition, and cannot adjust your premium based on how much you earn. Instead, premiums are set per canton (and often per premium region within a canton), per age group (children, young adults 19-25, and adults 26+), and per insurer. That means the same insurer can be the cheapest option in Zurich and one of the more expensive ones in Geneva, and the “best” insurer genuinely changes from year to year as each company resets its pricing.
Because of this, there is no single figure that is “the cheapest health insurance in Switzerland” – only a cheapest option for your specific canton, age, deductible and model. The only reliable way to find it is to run your own details through the official comparison tool (see below).
The two levers that actually move your premium: deductible and model
Once you’ve picked a canton (fixed – you insure where you live) and your age bracket applies automatically, you control two things:
- Deductible (Franchise/franchise): For adults, you choose a deductible between CHF 300 and CHF 2,500 per calendar year (in CHF 100 or CHF 500 steps). You pay medical costs yourself up to that amount before insurance starts covering costs (minus a 10% co-payment on top, capped annually). A higher deductible means a lower monthly premium – it’s a trade-off between a lower guaranteed monthly cost and higher risk if you actually need care. Children have a separate, lower deductible range starting at CHF 0.
- Insurance model: The standard model lets you see any doctor or specialist freely and costs the most. A family-doctor (Hausarzt) model requires you to consult your registered GP first before seeing a specialist (except in defined cases like gynaecology or ophthalmology), and typically costs less. A telmed/HMO model requires you to call a telephone medical helpline (or visit a specific HMO practice) before other treatment, and is usually the cheapest of the three because it reduces unnecessary specialist visits.
Combining the maximum deductible (CHF 2,500) with a telmed or Hausarzt model is typically how people find the lowest possible premium for their situation – but it only makes sense if you’re comfortable covering more out-of-pocket cost if something happens, and if you’re willing to accept the extra step of calling ahead or seeing your GP first.
What premiums actually look like in 2026
Figures last checked 22 July 2026, sourced from the Federal Office of Public Health (BAG) and its official Priminfo premium portal.
According to the Federal Office of Public Health’s official announcement (23 September 2025) on 2026 premiums, the nationwide average (“mittlere”) premium across all insurers, models and deductibles will be CHF 393.30 per month in 2026, an increase of about 4.4% (roughly +CHF 16.60) on 2025. Broken down by age group, the BAG’s published averages for 2026 are:
- Adults (26 and over): around CHF 465.30/month on average (up about 4.1%)
- Young adults (19-25): around CHF 326.30/month on average (up about 4.2%)
- Children (0-18): around CHF 122.50/month on average (up about 4.9%)
These are national averages of what people actually pay across all deductible levels and models combined – not the lowest price available. Because premiums are set per canton and change every autumn, the only way to see a real, current number for your own situation is the government’s own comparison tool. We deliberately have not listed canton-by-canton or insurer-by-insurer premium figures here, because we could not independently verify a granular breakdown beyond the national age-group averages above, and a wrong or stale franc figure would be worse than no figure at all.
How to actually compare and find your cheapest option
The Federal Office of Public Health runs a free, advertising-free, anonymous comparison tool at priminfo.admin.ch. Enter your postcode, birth year and preferred deductible/model, and it returns every insurer legally licensed to sell basic insurance in your area, ranked by actual monthly premium for 2026. This is the only source that reflects the current, government-approved premium list – comparison sites run by brokers can be useful for supplementary insurance advice, but always cross-check the basic-insurance premium figure itself against Priminfo, since broker sites are sometimes incentivised toward insurers that pay them commission on supplementary products.
Well-known Swiss basic insurers
Basic insurance (LAMal/KVG) is offered by dozens of licensed insurers in Switzerland. Some of the largest and best-known include:
- CSS – one of Switzerland’s oldest and largest health insurers
- Helsana – the country’s largest health insurance group by membership
- Swica
- Sanitas
- Concordia
- Assura – one of the largest by number of insured, historically known for competitive basic-insurance pricing in several cantons
None of these is reliably “the cheapest” everywhere or every year – their relative ranking shifts by canton and by year as each insurer resets its premiums every autumn. Treat this as a list of major, established, licensed providers worth including when you run a comparison, not a ranking.
When you can switch
For basic insurance, the standard annual switching window closes on 30 November, effective for a change starting 1 January the following year (per the official rule confirmed on priminfo.admin.ch). Priminfo recommends sending your written cancellation by 15 November by registered post or “A-Post Plus” so it is provably received by your current insurer before the deadline. You must have arranged a new policy to start immediately after the old one ends – there’s no gap allowed in mandatory coverage. If you want to change only your deductible level for the following year (without changing insurer), the same 30 November deadline applies.
Outside of this annual window, you can generally only switch insurer (not deductible) if you have a qualifying reason, such as moving to a new canton or turning into a new age bracket – check directly with your insurer or priminfo.admin.ch for your specific situation.
The bottom line
There’s no single “cheapest Swiss health insurer” – only a cheapest combination of canton, age bracket, deductible and model, recalculated every year. Use the free official Priminfo calculator with your real postcode and birth year, compare the standard, family-doctor and telmed models side by side, and confirm your notice is in by 30 November (sent by 15 November to be safe) if you want to switch for the following year.
