THE ESSENTIALS
The rental guarantee in Brussels is a sum of money your landlord can ask for at the start of your lease. It’s there to protect them if you don’t pay your rent or if you cause damage. Since November 1, 2024, it can’t exceed two months’ rent (excluding charges), and you have several ways to block it. You normally get it back at the end of your lease, if everything is in order.
WHAT YOU NEED TO KNOW
In Brussels, the rules for rental guarantees are clear and valid in 2026.
- How much? For leases signed or renewed from November 1, 2024, the rental guarantee cannot exceed the equivalent of two months’ rent, not including charges. This amount is based on the basic rent in your contract and doesn’t change if your rent is indexed annually.
- Where to block it? You choose how to block your guarantee from five possible options for recent leases (since November 1, 2024):
- A blocked bank account in your name, where the money earns interest for you.
- A bank guarantee via a special contract between a CPAS and a bank.
- A bank guarantee that allows you to repay the sum in constant monthly installments over a maximum of three years.
- A real security (a pledge or a mortgage) with a financial institution.
- A personal guarantee, where someone acts as a guarantor for you.
The guarantee can no longer be paid in cash; it must be deposited into a bank account.
HOW TO DO IT
- To block your guarantee:
- Choose one of the five forms of rental guarantee that suits you best.
- If you opt for a blocked account or a bank guarantee, contact your bank. Most banks have standard forms for you and your landlord to sign.
- If you have financial difficulties, you can inquire with the Fonds du Logement de la Région de Bruxelles-Capitale. They can help you with an interest-free loan or via the BRU-GAL fund, under certain income conditions, in 2026.
- Make sure the guarantee is properly blocked in your name and that your landlord cannot access it without your agreement or a court decision.
- To recover your guarantee:
- At the end of your lease, conduct a detailed exit inventory with your landlord. This is super important to prove the condition of the dwelling.
- Make sure you have paid all your rent and charges until the very end.
- If everything is in order, you and your landlord must sign a written agreement to release the guarantee. Often, this is a form your bank provides.
- The bank will return the guarantee and interest within two months after your departure and the return of the keys, if the agreement is signed.
- If your landlord refuses to sign or doesn’t respond, you can
