Best mutuality (health insurance fund) for expats in Belgium (2026)

In Belgium, your health insurance does not come from your employer or from a private insurer. It comes from a mutuality (mutualité in French, ziekenfonds or mutualiteit in Dutch, Krankenkasse in German). You join one, it registers you in the national system, and from then on it refunds part of your doctor visits, medicines and hospital bills. Without a mutuality you pay the full price of everything.

This guide is for people who have just moved to Belgium, or are about to, and need to pick a fund. Most newcomers discover the system late: they register at the commune, start a job, and only find out at their first pharmacy visit that nobody signed them up. The employer does not do it for you.

The good news is that the core refunds are identical everywhere, because they are set by law. What really decides your choice is practical: whether the fund speaks English, how much its membership fee is, whether you can join online, which region you live in, and which hospital insurance it sells, since that is only open to its own members.

How the Belgian system works

Statutory cover and complementary insurance

Mutualities pay healthcare and incapacity benefits under INAMI control; to receive them you must join a mutuality. (source, checked 2 November 2026) The amount refunded for a GP visit or a hospital night is the same at every fund, because it comes from the compulsory insurance managed by INAMI (RIZIV in Dutch), the national health insurance institute.

On top of that, each fund runs its own complementary insurance. Members pay a contribution to their mutuality and, when in order, receive its complementary insurance (extra services and advantages). (source, checked 2 November 2026) These extras are where funds compete: refunds for glasses, sports clubs, birth premiums, holiday camps for children, home help, travel assistance. The membership fee pays for them. It is not optional at a private mutuality: you pay it to stay a member in good standing.

If you stop paying, the consequences are serious. The Liberal Mutuality and Freie Krankenkasse both state that after a long period of unpaid contributions, complementary benefits stop and only reopen after a waiting period. Freie Krankenkasse adds that its hospital policies with MLOZ Insurance end too. Set up a direct debit when you join.

Five unions and one public fund

Mutualities are grouped into five national unions: Christian, neutral, socialist, liberal and free (independent); you can also choose the public CAAMI. (source, checked 2 November 2026) The national unions are the Christian, neutral, socialist, liberal and free (independent) mutualities. Each union groups several local or regional funds. The OCM/CDZ publishes the official list of national unions, mutualities and sociétés mutualistes; the 25/06/2026 list includes funds 100-900. (source, checked 2 November 2026) The political or religious labels are historical; they make no difference to the statutory refunds you receive.

At the CAAMI you pay no contribution but receive no complementary insurance. (source, checked 2 November 2026) That public fund, CAAMI in French and HZIV in Dutch, is a real option if you only want the legal minimum, but it means no extras at all and no hospital plan from a mutuality.

The private funds are large organisations. In 2024 the five unions together counted 8,077,546 mutualist households in complementary insurance. (source, checked 2 November 2026) You are not choosing a small club: every fund in this guide has offices, a call centre and an online account.

If you do not pay social security contributions

Employees and self-employed people are insured through the contributions they already pay. People who live in Belgium without paying contributions, for example a partner who does not work yet or a resident without professional income, are treated differently. Residents who pay no social-security contributions owe a personal contribution collected by their mutuality, set by income. (source, checked 2 November 2026) The amount is the same at every fund, so it should not influence your choice. Check the current income brackets on the INAMI page on the personal contribution.

Hospital insurance is tied to the fund

Statutory insurance only covers part of a hospital bill, and a single room brings extra charges on top. Most people add a hospital plan. Each union sells its own through a mutual insurance company (société mutualiste d’assurances) supervised by the control office for mutualities, the OCM/CDZ. The free mutualities, including Partenamut, Helan and Freie Krankenkasse, sell Hospitalia plans insured by MLOZ Insurance. Partenamut, Helan and Freie Krankenkasse are the sellers; MLOZ Insurance is the insurer.

The rule that matters: a mutuality hospital plan is only sold to members of that mutuality. If you already know which hospital plan you want, that choice largely decides your fund. Our guide to hospitalisation insurance in Belgium compares the plans.

How to choose a mutuality as a newcomer

Language. Few funds work in English. In our checks, only Partenamut runs a dedicated English-speaking service for expats, Helan has a full English website, and the public CAAMI has English information pages but forms in French, Dutch or German. Every other fund we read works only in French, Dutch or German. Even at the English-friendly funds, general conditions are in French or Dutch.

The membership fee. The published fees look easy to compare, but they are not like-for-like. Partenamut charges per titular, with dependants free. Helan quotes a price per adult. Neutraal Ziekenfonds Vlaanderen charges per member booklet, Solidaris shows its Wallonia fee, and Mutualia’s homepage figure does not say whether it is per person or per household. Read the basis before you compare, especially if you have a partner or children.

Region. Some funds work mainly in one region and one language. Solidaris has separate funds per area, so the Wallonia fee does not apply in Brussels. In Flanders, everyone also pays the Flemish care contribution (Vlaamse zorgpremie) on top of the fund fee.

Joining online. Partenamut, Helan, Mutualia, Solidaris and Freie Krankenkasse offer online registration. For the others, we did not find an online process on the pages we read.

Assistance abroad. Members of the Christian, socialist, liberal and neutral funds use the Mutas alarm centre for medical assistance on holiday. Helan members use Mediphone Assist. This is assistance, not full travel insurance: see our guide to travel insurance in Belgium.

The providers compared

Christian Mutuality: not checked

The Christian Mutuality (Mutualité chrétienne, MC, in French; Christelijke Mutualiteit, CM, in Dutch) is the largest union in Belgium by number of member households. We could not read its offer: both mc.be and cm.be refused our access when we checked on 2 November 2026. We therefore cannot confirm its fee, its languages or its joining process, so it is listed as not rated under the table rather than scored: this reflects missing data, not a judgement of the fund. Its members use the Mutas alarm centre abroad. If you are considering it, read the current conditions on the Christian Mutuality site.

Situations that change the choice

If you are an EU citizen

Bring your European Health Insurance Card (EHIC) or, if you were insured in another EU country, the form that proves your previous insurance periods. Helan’s expat page names these documents and explains that some benefits depend on past insurance. If you live in another EU country and only work in Belgium, Helan states that you still join a Belgian fund to obtain an S1 or S072 form, which lets you use your cover where you live.

If you are from outside the EU

You need proof of legal residence before a fund can register you. At the CAAMI, that means a residence card A, B or C, or an Annex 15 together with a valid type D visa. Private funds ask for similar documents; Partenamut sends its own list by e-mail. Rules on whether you need private insurance for your visa are set by the Immigration Office, not by the funds. Check them on the Immigration Office site.

If you live in Flanders

Add the Flemish care contribution to whatever fund fee you compare. Helan and Neutraal Ziekenfonds Vlaanderen are the two Flemish options with published fees; Helan is the only one with English pages.

If you live in Brussels

You can join any fund. Partenamut has the expat desk, Helan the English website, Mutualia a neutral French-language option. Remember that Solidaris in Brussels is Solidaris Brabant, with its own amounts.

If you live in Wallonia or East Belgium

Partenamut is the English-speaking option. Solidaris and Mutualia work in French. In the German-speaking area, Freie Krankenkasse works in German.

If your partner does not work

Your partner may be insured as your dependant. At Partenamut, dependants pay no fee; at Solidaris, dependants without income are free. If your partner lives in Belgium with no income and is not your dependant, the income-based personal contribution described above applies.

If you are a student

The CAAMI offers a specific student status. Our expat health insurance guide explains it, and the private options available before you join Belgian insurance.

Step by step: joining a mutuality

1. Register at your commune. You need an address in Belgium and, as a non-European, your residence documents (a residence card, or an Annex 15 with your type D visa at the CAAMI).
2. Choose your fund. Decide first whether you want a hospital plan, and which one, because it is only open to members of the same fund.
3. Start the application. Online at Partenamut, Helan, Mutualia, Solidaris and Freie Krankenkasse; on paper at the CAAMI. Partenamut lets you begin before you arrive.
4. Send the documents. Identity and residence documents and proof of your status (employment, self-employment, studies). EU citizens add their EHIC or insurance history.
5. Set up the direct debit for the membership fee, so your complementary benefits never lapse.
6. Ask for your hospital plan once you are a member, and note the waiting period that applies.

Switching later

You can change fund. The new fund handles the transfer and contacts your old one, and the change takes effect on the first day of a quarter. The request must reach the new fund early in the month before that quarter; Helan and Mutualia publish slightly different cut-off dates, listed in the questions below. If you have a hospital plan, ask the new fund whether your insurance can be transferred without a new waiting period, as Helan says it allows.

Our verdict

Helan comes out ahead in the table, but your region and your need for a person to talk to decide. For most English-speaking newcomers who want phone help, Partenamut is the safest first choice: an expat desk you can call in English, registration you can start before arriving, and free cover for dependants. Helan costs less per adult; it is the better pick in Flanders, or in Brussels if you are happy to manage everything online through an English website. If you only want the legal minimum, or you are a student, the public CAAMI charges no membership fee but gives no extras. Neutraal Ziekenfonds Vlaanderen and Mutualia are good value if you read Dutch or French, Freie Krankenkasse is the natural choice in East Belgium, and Solidaris works for French-speaking families in Wallonia. Whatever you choose, join early: until you are registered, every doctor’s bill is yours to pay in full.
