Belgium sits at the heart of Europe and, thanks to the EU institutions and NATO, hosts a large and truly international community in Brussels.
Its healthcare is excellent and widely praised, but there is a legal step every resident must take: joining a health insurance fund, or mutuelle.
Healthcare in Belgium: how the system works
Public system: Statutory health insurance via mutualité / ziekenfonds.
Belgium runs a compulsory statutory health insurance system administered through non-profit health funds — mutualités in French, ziekenfondsen in Dutch — and overseen nationally by INAMI/RIZIV. Patients usually pay upfront and are reimbursed a large share, with a modest co-payment (ticket modérateur) remaining. Care is high quality with short waits and a free choice of doctor, which is why Belgium consistently ranks near the top in Europe.
As a resident you must affiliate with a health fund to be covered (see below). UK State Pensioners can use the S1 form to access the system at the UK's expense. A UK GHIC only covers short stays, and your UK domestic policy will not cover you as a Belgian resident. Because patients face co-payments, most people, locals and expats alike, also take supplementary hospitalisation cover.
Is health insurance mandatory in Belgium?
Affiliation with a Belgian health insurance fund is compulsory for residents. After registering in your commune you must join a mutualité/ziekenfonds (or the public auxiliary fund) to be covered by statutory health insurance; membership is a legal condition of residence and gives access to reimbursed care. Statutory cover leaves co-payments, so most residents add supplementary hospitalisation insurance on top, through their fund, an employer or a private insurer.
Why British expats take out private cover
Even with statutory cover, co-payments and the upfront-then-reimburse model lead most residents to hold supplementary and hospitalisation insurance. For internationally mobile Britons, IPMI goes further — a free choice of hospital, private rooms, and cover that travels across borders with repatriation. It is especially useful for the large expat workforce that moves frequently for work.
What expat health insurance costs in Belgium
Statutory contributions come with employment, and health funds charge small membership fees, so core cover is affordable. Supplementary hospitalisation insurance is inexpensive to moderate, while comprehensive international policies cost more but add global cover and evacuation. Your premium reflects age, health and the breadth of cover.

How a UK broker helps expats in Belgium
International private medical insurance is a specialist market, and the right policy depends on your visa, your age, your medical history and how much time you spend outside Belgium. A UK-based specialist broker can compare the international insurers available through its service, check that a policy meets any local or visa requirement, and explain what is — and is not — covered before you commit.
A broker can compare only the insurers and policies available through its service, and may receive commission or charge a fee. Ask for the insurer panel, the remuneration disclosure and the total price. Requesting a quote is free and puts you under no obligation to buy.
Expat health insurance in Belgium: FAQs
Is health insurance compulsory in Belgium?
Yes. Residents must affiliate with a health insurance fund — a mutualité or ziekenfonds, or the public auxiliary fund — to be covered by statutory insurance. It is a legal condition of living in Belgium. Because cover leaves co-payments, most people also add supplementary hospitalisation insurance.
What is a mutuelle or ziekenfonds?
It is a non-profit health insurance fund that administers Belgium's statutory health cover. After registering in your commune you choose a fund to join, which then handles your reimbursements. Many funds also sell supplementary packages for hospital stays and extras.
Does my UK health insurance work in Belgium?
No. A UK domestic policy is designed for UK residents and will not cover you living in Belgium. You must join a Belgian health fund and can add supplementary or international private cover. A GHIC only helps on short visits.
Why do expats in Belgium buy supplementary insurance?
Statutory cover reimburses most costs but leaves co-payments, and patients often pay upfront first. Supplementary hospitalisation insurance covers the gaps, private rooms and extras. Internationally mobile expats often prefer full IPMI for cross-border cover and repatriation.
Can UK pensioners access Belgian healthcare?
Yes. UK State Pensioners can use the S1 form to access the Belgian system at the UK's expense, after affiliating with a health fund. Many still add supplementary cover for co-payments and choice. Confirm the current process when you register.
