When I first arrived in Spain, figuring out health insurance was a real headache. The information online was overwhelming, confusing, and full of ads. After living here for a few years, I’ve gotten the hang of it. Today, I’m sharing what I’ve learned about Spanish health insurance to help new arrivals avoid the same struggles.
Public or Private? That is the Question
Simply put, if you have a job and your employer pays into social security for you, you’re covered by public healthcare. The main advantages of the public system are its broad coverage and that it’s mostly free at the point of service, making it very reliable for serious illnesses or surgeries. However, the downside is significant: it’s slow! Waiting several months for a specialist appointment is common, and the service experience can feel a bit impersonal, like an assembly line.
Private insurance is a different story. Its biggest advantages are speed and convenience. Same-day appointments and seeing a specialist within a few days are the norm. The hospitals are modern, the service is attentive, and many offer English-speaking staff. Of course, the drawback is that you have to pay for it yourself. For most students and expats applying for a visa or renewing their residency, a private Spanish health insurance policy that is “Sin copago” (no co-payment) and “Sin carencia” (no waiting period) is a mandatory requirement.

How to Choose Among the Major Private Insurance Companies?
There are many private insurance companies in Spain, but the most common ones are Adeslas, Sanitas, and Asisa. Think of them like the major mobile carriers in any country—each has its own network and strengths. The differences aren’t huge, so the choice mainly depends on your budget and the network coverage in your area.
| Insurance Company | General Reputation | Best For |
| Adeslas | Widest network, with a huge number of affiliated hospitals and clinics | Those who prioritize convenience and want a network clinic nearby |
| Sanitas | Excellent service experience, particularly strong in the Madrid region | Those with higher expectations for facilities and service quality, and a slightly larger budget |
| Asisa | Great value for money, with relatively affordable prices | Students or young people on a budget who still need comprehensive coverage |
Before you buy, it’s crucial to check their official websites using your postal code to see the affiliated medical centers. See how many hospitals and clinics are close to your home—this is very important! You don’t want to buy a policy only to find out all the network hospitals are on the other side of the city.
If you’re renewing your residency or have just arrived, a basic, comprehensive private plan is a necessity. Prices typically range from 40-60 euros per month, depending on your age. If you already have a job with social security coverage but want to improve your healthcare experience, you can get a private plan as a supplement. Choosing a plan with ‘Copago’ (co-payment) will be much cheaper. I hope my sharing is helpful, and feel free to add your own experiences!
