Sanitas vs Adeslas vs Asisa vs DKV: Best Private Health Insurer in Spain for Expats

If you are relocating to Spain from the US, Canada, or another European country, private health insurance is often part of the plan — whether because your visa requires it, because you want faster specialist access, or because you want English-speaking doctors. Four insurers dominate the market: Sanitas, Adeslas, Asisa, and DKV. They cover most of the country, contract with the best private hospitals, and issue the "full-coverage, no co-payment" certificates that Spanish consulates typically accept for non-lucrative, digital nomad, and student visas.

This guide compares the four so you can pick with confidence. Rules, networks, and premiums change every year — always request a current quote and read the policy conditions before signing, and confirm visa-specific requirements with your nearest Spanish consulate.

Why private insurance matters for expats

Spain has an excellent public system (Sistema Nacional de Salud), but you can only access it once you are legally registered, contributing to Social Security, or covered through a bilateral agreement. For your first year on a Spanish visa, most foreigners need a private policy that:

• Covers you across Spain with no co-payments (sin copagos)
• Has no waiting periods (sin carencias) for the main treatments
• Provides a certificate stating it is equivalent to public coverage

All four insurers below sell a specific "visa-compliant" product designed to meet these consular requirements. Confirm the exact wording your consulate expects before you buy.

The big four at a glance

Sanitas (part of Bupa)

Sanitas is the go-to for English-speaking expats, particularly in Madrid, Barcelona, Marbella, Valencia, and the Balearics. Because it belongs to the UK-based Bupa group, its customer service, app, and international support feel familiar to Anglophones.

• Network strength: Owns its own hospitals (Hospital Universitario Sanitas La Moraleja and La Zarzuela in Madrid, plus CIMA in Barcelona) and contracts with many others.
• Best for: Expats who value English service, digital tools, and integrated hospital ownership.
• Watch-outs: Premiums tend to be at the higher end of the four. Some regions (rural interior, smaller islands) have a thinner network.
• Nice extras: Strong telemedicine (Sanitas 24h video consultations), robust dental add-on (Sanitas Dental), and a good international upgrade for frequent travellers.

Adeslas (SegurCaixa Adeslas)

Adeslas is the market leader by number of policyholders and generally the broadest network in Spain. If you plan to live outside a major city, or you move often between regions, Adeslas is hard to beat on sheer access.

• Network strength: The largest medical directory of the four; near-universal presence in every province.
• Best for: Families, retirees on non-lucrative visas, and anyone in a smaller town.
• Watch-outs: Customer service is largely in Spanish; English-speaking specialists exist but are not the default. The app and digital experience are functional but less polished than Sanitas.
• Nice extras: Competitive family bundles, strong dental (Adeslas Dental) sold separately, and a well-regarded maternity module.

Asisa

Asisa is a medical cooperative — it is owned by doctors — which gives it a distinct culture and often competitive pricing. It is a solid mid-market option, especially strong in the Levante (Valencia, Alicante, Murcia) and Andalusia.

• Network strength: Owns HLA hospitals across Spain (a respected private hospital group) and has a wide contracted network.
• Best for: Budget-conscious expats who still want brand-name coverage and hospital ownership behind the policy.
• Watch-outs: English-language support varies by clinic; less international-friendly than Sanitas or DKV. Digital tools are improving but not best-in-class.
• Nice extras: Reasonable premiums for older applicants compared with some rivals; visa-compliant products are clearly marketed.

DKV (part of Munich Re / ERGO)

DKV is the German-owned option and often the favourite of Northern European expats. It has invested heavily in digital health, prevention, and mental-health coverage.

• Network strength: Solid nationwide, particularly strong in Catalonia, Zaragoza, and the Costa Blanca. Owns clinics in several cities.
• Best for: Younger expats, remote workers, and anyone who values mental-health and preventative coverage.
• Watch-outs: Not always the cheapest, and English service is inconsistent — often good in Barcelona, less so elsewhere.
• Nice extras: Quiero cuidarme app is one of the best in the market, generous psychology/psychiatry sessions, and strong environmental-sustainability commitments.

How to actually compare quotes

Prices in Spain depend heavily on your age, region, and whether you take co-payments. A 30-year-old in Valencia will pay a fraction of what a 65-year-old in Madrid pays for the same policy. Rather than quoting figures that will be wrong for you, here is what to compare line-by-line when you request quotes:

1. Waiting periods (carencias) — for surgery, childbirth, and complex diagnostics. Visa policies should waive these; confirm in writing.
2. Co-payments (copagos) — some cheaper tiers charge €3–€15 per visit; visa-compliant plans usually have none.
3. Hospital network — check that the hospitals you would actually use in your city are on the list. Ask for the "cuadro médico" PDF.
4. Annual limits on physiotherapy, psychology, and complex tests.
5. Dental — almost always sold as a cheap add-on with its own price list; compare included vs. discounted treatments.
6. International coverage — how many days abroad are covered, and is the US included? US coverage is usually an expensive upgrade.
7. Renewal terms — can they refuse to renew? Can they raise your premium at 65 or 70? Ask directly.

Use an independent broker (correduría) rather than a captive agent: they can quote all four at once and often at the same price as going direct.

Which one should you pick?

• You want English service and a smooth digital experience → Sanitas
• You live in a smaller town or want the widest possible network → Adeslas
• You want good coverage at a lower price, especially in eastern/southern Spain → Asisa
• You are younger, digitally minded, or prioritise mental health → DKV

For most non-lucrative and digital nomad visa applicants who settle in Madrid, Barcelona, Valencia, Málaga, or the islands, the realistic shortlist is Sanitas or Adeslas. Sanitas wins on English and app; Adeslas wins on breadth and often price.

Common mistakes to avoid

• Buying the cheapest plan that fails your visa. Basic policies with co-payments are rejected by many consulates. Ask specifically for a póliza equivalente a la sanidad pública española.
• Ignoring pre-existing conditions. All four insurers ask a health questionnaire. Undisclosed conditions can void claims. Declare everything.
• Assuming you can switch mid-year. Policies are annual. Switch at renewal to avoid losing waiting-period credit.
• Forgetting the certificate. You need a signed certificado de cobertura for the consulate, not just the contract.
• Overlooking rural coverage. If you plan to move to a village, verify the nearest network hospital before signing.

Short FAQ

Do I still need private insurance once I have residency? Not legally, if you gain access to the public system through work, self-employment, or the convenio especial. Many expats keep private cover anyway for faster specialist appointments.

Can I keep the same insurer if I move regions within Spain? Yes — all four operate nationwide, but check the network in your new city before renewing.

Is US medical care covered? Rarely as standard. Sanitas and DKV offer international upgrades; US coverage is a premium add-on and often capped.

Can I be turned down for age or health? Yes. Insurers can decline applicants, exclude conditions, or price higher after roughly age 65–70. Apply while healthy if you can.

Bottom line: any of the four will serve you well if you match the plan to your city, age, and language needs. Get quotes from all four through a broker, read the exclusions, and confirm your consulate's exact wording before you pay. Rules and premiums shift each year — verify current terms with the insurer and, for visa questions, with your Spanish consulate or a licensed immigration lawyer before you commit.
