Moving to Belgium: what to know before you go

What should you know before moving to Belgium?

Three things shape a move: the region you land in, the commune you register with, and your status as an EU or non-EU citizen.

Belgium had 11,867,634 inhabitants on 1 January 2026. Of them 1,635,132, or 13.8%, were non-Belgians, and the international migration balance in 2025 was positive at +47,562 (Statbel, 10 Jun 2026; origin figures). The Brussels-Capital Region stands apart. Only one resident in two there was born in Belgium in 2026, against about eight in ten in Flanders and Wallonia, and Brussels’ population was almost unchanged in 2025, up by only 39 people.

The country has three regions, Flanders, Wallonia and Brussels, and the Brussels-Capital Region has 19 communes that, in the commissioner’s words, each work differently. The Flemish government’s guide for newcomers focuses on Dutch language learning, while the Brussels Expat Welcome Desk works in English, French, Dutch and Spanish (Commissioner Brussels, read 7 Oct 2026). So ask your own commune which documents it wants.

Can you move to Belgium without a job?

EU citizens may stay up to three months and then apply for a registration certificate at the commune, within three months of arrival. The Brussels commissioner lists the conditions by status: workers show an employment contract, self-employed people a business registration and social security affiliation, people with sufficient means proof of income, students enrolment and health insurance, and job seekers an enrolment with Actiris or copies of job applications (Commissioner Brussels, read 7 Oct 2026).

Non-EU citizens typically obtain a D visa, the long-stay visa, from the Belgian embassy at home before they arrive. It needs a passport valid for at least 12 months, a medical certificate, a good-conduct certificate and papers for your status: employment, studies or family reunification (Commissioner Brussels, read 7 Oct 2026). So a non-EU citizen cannot simply move without a basis for the stay.

What is the single permit?

For an employee from outside the EU, the route is the single permit. Brussels describes it as an electronic card that gives the right to work and to live in Belgium (Commissioner Brussels, read 7 Oct 2026). Your employer or its representative asks for the authorisation, and the procedure can take up to four months. The Brussels economy and employment service says a single permit certifies the right to stay and work for more than 90 days, and that since 4 May 2026 employers must apply through the federal one-stop counter (Brussels Economy and Employment, read 7 Oct 2026). You supply papers such as a medical certificate, your education certificate, a criminal record extract and a passport copy. Ask your employer which part of the process it manages, and who is the contact.

What do you do in the first days?

Register at your commune. This is the legal first step. The Brussels Region says it is vital for the residence permit and unlocks access to the job market, social security and private services (Brussels-Capital Region, read 7 Oct 2026).

The deadline depends on your status. EU citizens present themselves to the commune within three months of arrival to apply for the registration certificate. Non-EU citizens register within eight working days of arrival (Commissioner Brussels, read 7 Oct 2026). The Flemish government’s page tells newcomers to register with the municipality within three working days of entering Belgium (Flemish government, read 7 Oct 2026). We cannot reconcile the three figures, so book your appointment as soon as you have an address.

Since 1 September 2025 EU citizens must hand in a complete file at the first appointment, or the commune cannot process it. After the appointment the police check that you live at the declared address, and you receive a provisional national register number of 11 digits (Commissioner Brussels, read 7 Oct 2026). Non-EU citizens then receive an A card, issued after about a month and valid for a year as a rule, and a B card after five years of continuous legal residence. The full list of steps is in settling-in services in Belgium.

Join a mutuality. Belgian residents enrol with a mutuality (mutualité in French, ziekenfonds in Dutch) to activate health coverage, which the Brussels Region describes as broad (Brussels-Capital Region). We have not researched the mutualities, the contribution or the refund, and we give no advice on products.

How hard is it to find a home in Brussels?

The Brussels commissioner’s housing page says Brussels has a plentiful supply of relatively inexpensive accommodation, making it fairly easy to find a place that suits your needs (Commissioner Brussels, read 7 Oct 2026). That is a public body’s view, not a statistic.

For a number, there is Numbeo, a crowd-sourced site. On 6 October 2026, after 1,071 entries in the past 12 months from 127 contributors, it estimated a one-bedroom flat in the centre of Brussels at EUR 1,197 a month (range EUR 1,000 to 1,500), one outside the centre at EUR 1,031, a three-bedroom in the centre at EUR 2,205 and one outside at EUR 1,798 (Numbeo, read 7 Oct 2026). These are estimates, not official rents.

The rules are what trips people up. In Brussels a long-term home lease for a main residence runs nine years even when written shorter. The usual guarantee is a blocked bank account of up to two months’ rent, and paying it in cash or by transfer to the owner’s account can cost you the claim if the owner becomes insolvent. The landlord must register the lease within two months, free of charge for homes (Commissioner Brussels, read 7 Oct 2026). The search itself is in how to find an apartment in Brussels.

What does the move cost?

We found no official total, so here are the parts we can source. Rent is the large one; see the estimates above. On top comes the rental guarantee: in Brussels up to two months’ rent on a blocked account, or up to three months’ rent through a bank guarantee that you repay monthly to the bank, or the online e-DEPO system (Commissioner Brussels). Agency prices are the gap: we found no published price list from a Belgian agency. What that means, and what to ask, is in what a relocation agency costs in Belgium.

Where can a relocation agency help, and where not?

KBC Brussels lists five agencies and says they can help with the search for accommodation suited to your tastes and needs, supervise your move, and accompany you in most settling procedures: registration with the municipality, the rental contract, telecom and energy subscriptions, and enrolling your children at school (KBC Brussels, read 7 Oct 2026).

ReloFinder’s Belgium page lists 14 agencies with an office in Belgium on 7 October 2026: 7 in Brussels and 3 in Antwerp, with the rest elsewhere. If you move to Antwerp, Ghent or Leuven, expect fewer local choices than in Brussels, and ask any agency whether it covers your city. An agency does tasks. It does not change the rules, the commune’s file or the employer’s permit process. And there is a free alternative for the basics: the Expat Welcome Desk calls itself a free, independent public service and covers registering at the municipality, residence and work permits, rental contracts, family reunification, social security, education and taxes (Commissioner Brussels, read 7 Oct 2026). Belgium also has a national association, ABRA, whose member list named 16 full members when we read it on 6 October 2026 (ABRA). How to use it is in how to choose a relocation agency in Belgium.

School age is early. Education in the French Community is compulsory from age 5 to 18, with full-time attendance until 15 (Eurydice, read 7 Oct 2026). Flanders and the German-speaking Community run their own systems, which we did not research.

A 90-day plan

1. Before you move. Check your route: EU registration, or a D visa and a single permit. Ask your employer what it handles. Start the home search.
2. Day 1. Collect the keys and the signed lease. Pay the guarantee into a blocked account, not in cash.
3. Days 1 to 8. Non-EU: register at the commune within eight working days. EU: book the appointment and gather a complete file.
4. Weeks 1 to 4. Police residence check. Receive the provisional national number. Join a mutuality.
5. Month 2. Sort schools and childcare. EU: collect the registration certificate once granted.
6. Month 3. Non-EU: your A card should be in hand. Check your lease is registered, and the entry inspection is on file.

What we could not source

We did not find official processing times for the commune, the card or the single permit beyond the four months quoted above. We did not research driving-licence exchange, bank accounts, taxes, mutuality contributions, or schools in Flanders. We could not read the Immigration Office’s pages, which were behind a security check on 7 October 2026, so the deadlines rest on the Brussels commissioner and the Flemish government. We have no Belgian agency prices.
