When to Book Mid-Term Housing in Belgium: The Seasonal Calendar

The best apartment for your stay is often gone before you start looking, not because Belgium is short of furnished housing, but because everyone arrives in the same few weeks. This guide explains when to book mid-term housing in Belgium: which months are busiest in Brussels, Antwerp and Ghent, what drives each peak, how far ahead to book in each season, and what it takes to move in on the day you sign.

The short answer

September is the busiest month for mid-term housing in Belgium, so book early for an autumn start. After the summer holidays many new projects begin at once, and in Brussels, Ghent and Leuven the academic year starts in the same weeks.

As a rule of thumb:

• For a September arrival, start looking in June or July.

• For January, start in October or November.

• For the rest of the year, three to six weeks is usually enough.

• If you need to move in this week, it can still work, with fewer options to choose from.

The year at a glance

These are planning ranges, not guarantees. A single large project can fill a neighbourhood in any month.

September: the peak month

September is the peak because two calendars restart at once: business and education. Companies launch the projects that were signed off before the summer, teams that were on holiday in July and August arrive together, and employees who deferred a move until the school year come with their families.

The academic year adds a second layer. In 2026, classes started at ULB in Brussels on 14 September and at KU Leuven and Ghent University on 21 September. Most students rent student rooms rather than furnished apartments, but visiting researchers, PhD candidates, academic staff and students' families look for the same one- and two-bedroom apartments as project staff, in the same weeks.

What this means in practice: the widest choice for a September start is in June and July. By late August, the apartments left are usually the ones that are larger, further out or more expensive than planned.

January: a smaller second wave

January is often described as a second, smaller peak. New annual budgets open, projects approved in the autumn start, and some employers time relocations to the calendar year.

In Brussels, the EU calendar adds to this. The rotating presidency of the Council of the EU changes every six months, on 1 January and 1 July, which makes these natural start dates for postings linked to it.

January is less intense than September, but the booking window is shorter than it looks, because December holidays remove two weeks from everyone's planning. If you arrive in the first half of January, treat November as your deadline for choosing an apartment.

Brussels and the EU cycle

Brussels has its own rhythm on top of the Belgian one, because of the EU institutions, NATO, embassies and the organisations that work with them.

• The European Commission's Blue Book traineeships start on 1 March and 1 October and last five months. A five-month stay is exactly the length that suits a furnished mid-term rental.

• The Council presidency changes on 1 January and 1 July.

• Many diplomatic and institutional postings change over in late summer, which adds to the September peak.

If you are coming for an EU traineeship, a secondment or a posting with a fixed start date, book as soon as the date is confirmed. The communes around the EU Quarter are the first to fill.

Summer: holidays, then a rush

July and August are quiet on the ground and busy on the booking side. Many Belgian businesses close for part of the summer: in most of Flanders the construction holiday runs from mid-July to early August, and decision makers on the client side are away.

For you, summer is the moment to secure a September apartment. Arrivals in July and August themselves often find good availability, because the apartments that will be taken in September are still free.

How far ahead to book

Book by season, not by habit. Use this as a planning guide:

1. September arrival: start in June, sign by mid-July if the date is fixed.

2. January arrival: start in October, sign by the end of November.

3. Team arrival of five or more people: add four weeks to any of the ranges above, because you need apartments close to each other.

4. Other months: three to six weeks ahead is usually enough.

5. Uncertain start date: book the most likely date and keep the contract short. With a contract of one to eleven months, you can extend later.

The longer you plan to stay, the earlier you should look. A one-month stay can fit into a gap between two tenants; a nine-month stay needs an apartment that is free for the whole period.

What same-day or next-day check-in takes

You can move into a Globexs apartment on the same day or the day after signing, if two things are done: the contract is signed and the payment arrives by instant transfer.

• Signed contract. Private tenants need an ID only: no payslips, no employer letter, no guarantor.

• Instant transfer. The move-in follows the payment, so use an instant bank transfer. A standard international transfer can take a few working days.

• No Belgian bank account needed. You can pay from your existing account.

Last-minute bookings work best outside September. In the peak month, same-day check-in is still possible, but the choice of apartments is narrower.

Where Globexs fits

Globexs has rented furnished apartments to expats and companies since 2002. In Belgium we have 135 published apartments in Brussels, Antwerp and Ghent, on contracts from one to eleven months, and house teams of 1 to 50 people. The average stay is 5.3 months.

• All-in price that includes energy, with no cap in euros.

• Antwerp from EUR 1,300 a month, Ghent from EUR 1,000 a month.

• Extension by one email if the project runs over.

• Move-in on the same or next day after signing and instant payment.

If your start date falls in September, tell us as soon as you know it.

Frequently asked questions

What is the busiest month to rent a furnished apartment in Belgium?

September. Many projects start after the summer holidays, and in Brussels, Ghent and Leuven the academic year begins in the same weeks. Book in June or July for a September start.

How far in advance should I book mid-term housing in Belgium?

Three to six weeks is usually enough for most of the year. For September, start two to three months ahead; for January, start in October or November.

Is January a busy month too?

It is often a smaller second wave, driven by new budgets, project kick-offs and, in Brussels, the Council presidency change on 1 January. Plan around the December holidays.

Can I move in on the day I sign?

With Globexs, yes: check-in is possible on the same or next day after the contract is signed and the payment arrives by instant transfer.

Is it easier to find an apartment in summer?

For arrivals in July and August, often yes. For a September start, summer is when you should be booking, not arriving without a plan.

I am starting an EU traineeship in Brussels. When should I book?

As soon as your start date is confirmed. Commission traineeships start on 1 March and 1 October and last five months, which fits a mid-term furnished rental.

What if my start date moves?

Tell us early. Contracts run from one to eleven months, and an extension takes one email, so it is safer to book a realistic date than to wait for certainty.
