Healthcare in Belgium runs through a health insurance fund, called a mutuelle or ziekenfonds, and GOV.UK says residents who live and work there need to join one and pay social insurance contributions. Your dependants are covered by your health insurance. Here is the order to do things in.

Quick answer

  • Register as a resident and get your national residency card first.
  • Sign up for social insurance contributions (employers usually do this; self-employed people register with NISSE).
  • Book an appointment with your chosen health insurance fund to join.
  • If you get a UK State Pension, you may qualify for an S1.

How do I register for healthcare in Belgium?

  1. Register as a resident and receive a national residency card.
  2. Sign up for social insurance contributions. Non-working residents may pay personal contributions directly.
  3. Book an appointment at the local office of your chosen health insurance fund. Your residency card will then show your membership.

What is a mutuelle and what does it cost?

GOV.UK describes the mutuelle as the health insurance fund you must join to live in Belgium. Joining typically costs 120 to 150 euros per year, on top of social insurance contributions. The fund can reimburse up to 80% of most medical costs, and surgery does not require payment upfront. Optional supplementary insurance is available.

Reimbursement Up to 80% of most medical costs
Surgery No payment upfront
Dependants Covered by your health insurance

Who can get an S1 for Belgium?

Residents who receive a UK State Pension or an exportable benefit may be eligible, and frontier workers may be too, so check with HMRC. You request the form by phone from NHS Overseas Healthcare Services, then register it with a Belgian health insurance fund. Your residency card is updated to show your entitlement. Dependants of a State Pensioner lose their cover once the State Pensioner starts claiming the UK State Pension. See UK State Pension abroad for the pension side.

What about posted workers and students?

Posted workers sent temporarily by a UK employer can use a GHIC, EHIC or S1. Students can use a Student GHIC for their study period.

Common mistakes

  • Trying to join a fund before you hold a residency card.
  • Forgetting that a spouse’s cover can end when a State Pension claim starts.
  • Skipping the social insurance step and assuming the fund fee is the only cost.

FAQ

Is joining a mutuelle optional?

The page I checked was last updated on 19 October 2021, so confirm costs with your fund.

Key takeaways

  • Residency card, then social contributions, then the fund.
  • Expect about 120 to 150 euros a year for the fund, plus contributions.
  • Pensioners should look at the S1.
