Every expat moving to the Netherlands hits the same wall within weeks of arrival: Dutch law requires basic health insurance, and the list of providers all look the same on the surface. This guide ranks the providers that actually matter for internationals in 2026, based on network size, English-language support, and how each one handles the gap before you have a BSN.
- Zilveren Kruis is the best overall pick among health insurance providers for expats moving to Netherlands in 2026.
- Cigna Global covers you internationally before your BSN and Dutch basisverzekering are active.
- VGZ runs the most budget-friendly basic package for singles and students.
- Dutch law requires basic insurance within four months of registering or starting work in 2026.
- ONVZ suits expats who want free choice of specialist over a fixed network.
Why this matters
The Netherlands runs mandatory basic health insurance, called basisverzekering, and every resident who registers or starts work has to buy it. Miss the enrollment window and the CAK, the Dutch care institution, can bill you retroactively for the months you went without coverage.
That deadline sits right on top of the housing timeline most expats are already juggling. You need a Dutch address to get a BSN before renting an apartment, and the BSN is what triggers the four-month clock on insurance. Get the sequence wrong and you're paying penalties on top of moving costs.
The basic package itself is standardized by the Dutch government: every insurer has to cover the same core treatments, GP visits, and hospital care. What separates providers isn't coverage, it's network size, English support, and how they treat you before your paperwork is finished.
What makes the best health insurance provider for expats
- English-language claims handling — a support line that doesn't route you through Dutch-only phone trees
- Contracted network size — how many GPs and hospitals near your rental are actually covered without extra cost
- Pre-BSN coverage options — whether you can get insured before your Dutch registration clears
- Deductible flexibility — how the eigen risico and supplementary add-ons are structured
- Corporate/group handling — whether the insurer works smoothly with employer-sponsored relocation packages
- Switch-window transparency — how clearly the insurer communicates the annual switching period

1. Zilveren Kruis: best overall health insurance for expats
Zilveren Kruis is the largest health insurer in the Netherlands, and that scale shows up in its contracted network of hospitals and specialists. For an expat who hasn't picked a neighborhood yet, that breadth matters more than any single feature.
Zilveren Kruis pros:
- Largest contracted-care network in the country
- Broad supplementary options for dental and physiotherapy
- Established claims process with an English-language portal
Zilveren Kruis cons:
- Supplementary packages run higher than budget insurers
- Popularity means longer wait times on the phone during peak enrollment months
Best for: expats who don't yet know which city they'll settle in long-term. Verdict: Buy.
2. CZ: best for English-language customer service
CZ built its reputation on service quality rather than pure network size, with support built for people who aren't fluent in Dutch. That's a real advantage in month one, when every other call you're making — bank account, BSN appointment, lease signing — is already in a foreign language.
CZ pros:
- Dedicated international/expat support line
- Clear online enrollment for non-Dutch speakers
- Fast digital claims processing
CZ cons:
- Network size trails Zilveren Kruis in some regions
- Basic package coverage is legally identical to competitors, so the premium difference is really about service
Best for: expats who want a human who speaks English on the other end of the line. Verdict: Buy.
3. VGZ: best budget-friendly basic package
VGZ keeps its supplementary premiums lower than the larger insurers while still meeting the same mandatory basisverzekering standard. For a student or a single professional on a tight budget in 2026, that gap adds up over a year.
VGZ pros:
- Lower-cost supplementary tiers
- Strong presence in university cities
- Simple online-only enrollment
VGZ cons:
- Smaller specialist network outside major cities
- Less brand recognition among corporate relocation teams
Best for: students and singles prioritizing cost over network breadth. Verdict: Buy.
4. ONVZ: best for free choice of specialist
ONVZ sells a restitutiepolis, meaning it reimburses care from almost any provider rather than restricting you to a contracted list. If you already have a preferred specialist from your home country's network who practices in the Netherlands, this structure removes the guesswork.
ONVZ pros:
- No fixed provider network to work around
- Straightforward reimbursement model
- Popular among expats who move between cities within NL
ONVZ cons:
- Fewer employer group-rate arrangements than the big insurers
- Reimbursement paperwork takes more effort than a contracted-network claim
Best for: expats with an existing specialist they don't want to lose. Verdict: Hold if you already have coverage elsewhere that works; Buy if switching for network freedom.
5. Cigna Global: best for coverage before a Dutch BSN
Cigna Global fills the exact gap that trips up new arrivals: the weeks between landing in the Netherlands and getting a BSN, when you're not yet eligible for basisverzekering but you're also not covered by your home country's plan anymore. Corporate relocation packages often include this as a bridge policy.
Cigna Global pros:
- Coverage active before Dutch registration completes
- Works across multiple countries, useful mid-relocation
- No dependency on a Dutch address to activate
Cigna Global cons:
- Not a substitute for mandatory basisverzekering once you're registered
- Running two policies briefly means paying for both during the transition
Best for: anyone arriving before their BSN and rental paperwork clear. Verdict: Wait — use it only as a bridge, then switch to a Dutch basic insurer.
6. Allianz Care: best for multi-country corporate assignments
Allianz Care shows up most often through employer-sponsored relocation packages rather than direct purchase. It's built for assignees whose postings might shift to another country mid-contract, not for someone settling permanently in one Dutch city.
Allianz Care pros:
- Coverage follows the employee across international postings
- Handles complex, employer-negotiated group terms
- Strong fit for destination services for employees relocating to the Netherlands
Allianz Care cons:
- Rarely available as a direct-to-consumer purchase
- Overkill for someone settling long-term in one Dutch city
Best for: corporate assignees with multi-country contracts. Verdict: Skip unless your employer is already arranging it.
How this ranking was built
Each provider was scored against the six criteria above — network size, English support, pre-BSN options, deductible flexibility, corporate handling, and switch-window clarity — using each insurer's published plan structure and market position as of 2026. Providers that only win on one dimension were kept lower on the list, since a single strength rarely outweighs a weak network or slow claims process.

Which health insurance provider should you choose?
If you're still deciding where in the Netherlands you'll live, Zilveren Kruis is the safest default because its network covers the most ground. If English-language support matters more than network breadth, pick CZ. Students and budget-conscious singles should default to VGZ, and anyone arriving before their BSN clears should treat Cigna Global as a short-term bridge, not a permanent plan.
Getting the insurance timeline right depends on getting the housing and registration timeline right first — a rushed relocation to the Netherlands for a new job is where most expats end up missing the four-month insurance window entirely.

FAQ
What's the best health insurance provider for expats moving to Netherlands?
Zilveren Kruis is the best overall pick for 2026 due to its network size, though CZ wins on English-language service and VGZ wins on cost for students and singles.
Is Dutch health insurance mandatory for expats?
Yes. Anyone who registers or starts work in the Netherlands must take out basic health insurance (basisverzekering), and the core coverage is standardized by law across every insurer.
How long do I have to sign up for Dutch health insurance?
You have four months from the date you become liable, typically when you get a BSN or start work, before the CAK can apply retroactive premiums.
Can I get health insurance before I have a BSN?
Yes, through an international provider like Cigna Global or Allianz Care, which cover the gap before Dutch registration completes. These don't replace basisverzekering once you're registered.
Is Zilveren Kruis better than CZ for expats?
Zilveren Kruis has the larger contracted network, while CZ is generally stronger on English-language support. The better choice depends on whether network size or service language matters more to you.
Do I need private international insurance if I already have Dutch basisverzekering?
Usually not, unless your employer requires multi-country coverage for a role that spans assignments outside the Netherlands.
What happens if I miss the four-month enrollment deadline?
The CAK can retroactively charge premiums for the uninsured period, on top of the premium you owe going forward once you enroll.
Can my employer choose my health insurance provider for me?
Employers can negotiate group rates or arrange bridge policies like Allianz Care for assignees, but individuals still choose their own Dutch basisverzekering provider.
One last thing
Most expats don't realize that switching Dutch health insurers is only allowed once a year, during the switch window that runs roughly from mid-December through the end of January. Pick wrong in 2026 and you're locked into that provider until the next window opens — so the first choice matters more than most people assume walking in.
