Best rental guarantee options in Belgium (2026)

You have found a flat, the landlord likes you, and now the agency asks for the rental guarantee (garantie locative / huurwaarborg) before handing over the keys. For someone who arrived a few weeks ago, this is often the first hard step: the bank wants a Belgian ID card you do not have yet, the agency suggests a provider you have never heard of, and the amount is two or three months of rent that must be ready before you move in.

This guide is for tenants who rent their main home in Belgium and need to lodge that deposit. It compares the three families of options that exist in law and in practice: a blocked bank account in your name, a surety company that issues a certificate instead of blocking cash, and public loans or guarantees for people who cannot pay upfront.

Three things decide the choice. First, the region where the property is, because Brussels, Flanders and Wallonia each have their own lease law. Second, whether you have the cash available and are willing to see it locked for years. Third, your paperwork: many options need a Belgian ID card, registration in the foreigners’ register, or a Belgian tax assessment, which newcomers often do not have yet.

How to choose a rental guarantee in Belgium

The cap depends on the region

The maximum deposit is set by regional law, not by the landlord. Brussels: for leases entered into or renewed from 1 November 2024, the deposit cannot exceed two months' rent. (source, checked 2 November 2026) Wallonia: since 1 June 2023 the guarantee is capped at two months' rent whatever its form. (source, checked 2 November 2026) Flanders: the deposit may not exceed three months' rent; forms are blocked account, real security, OCMW bank guarantee, and (with landlord's agreement) a surety. (source, checked 2 November 2026)

So a landlord in Brussels or Wallonia who asks three months on a new lease is asking more than the law allows. In Flanders three months is the ceiling, not a requirement. Read the lease: the amount and the form of the guarantee are written in it.

The legal forms

Each region lists the forms a guarantee can take. The core is the same everywhere: an individual blocked account in the tenant’s name at a financial institution, or a bank guarantee arranged through the CPAS/OCMW (public social welfare centre). Brussels Housing Code lists five forms: individual blocked account, CPAS bank guarantee, bank guarantee built up monthly over max 3 years, real security with a financial institution, personal guarantee. (source, checked 2 November 2026)

In Flanders the tenant decides. In Flanders the tenant chooses the form of the deposit; the landlord's agreement is needed only for a surety by a person or company. (source, checked 2 November 2026) This matters when an estate agency insists on one particular provider. The agency can say which forms the landlord accepts in the lease, but a blocked account in your name at a bank of your choice is a legal form the landlord cannot refuse in any region. A surety company is a different case, as explained below.

Paying the deposit in cash to the landlord, or by transfer to the landlord’s own account, is not one of the listed forms. If an agency asks for this, ask for a blocked account instead.

How the money comes back

Getting the deposit back follows one rule. Funds are released only on a written agreement drawn up after the lease ends, or on a copy of an enforceable judgment. (source, checked 2 November 2026) In practice you and the landlord sign a release form after the check-out inspection (état des lieux / plaatsbeschrijving), and the bank or institution pays out. If the landlord disputes damage and refuses to sign, the money stays blocked until you agree or a justice of the peace decides. This applies to blocked accounts and public deposits alike, so keep your entry inspection report and photos from the first day.

Traps for newcomers

• Several banks let non-customers open a rental guarantee account online, but only with a Belgian identity card. If you only hold a passport, plan a branch visit or another option.
• Regional 0% loans usually require registration in the population or foreigners’ register, and the Brussels scheme uses your latest Belgian tax assessment. Someone who arrived this year may not qualify yet.
• A surety is not free money. You pay a yearly fee that is never refunded, while a blocked deposit comes back to you with interest.
• Some agencies steer tenants to a provider they work with. You can choose another legal form.

The rental guarantee options compared

The table above ranks the options with our scoring method. Public schemes sit in the same list because they are real alternatives for many tenants, but they have eligibility rules that commercial products do not.

If you do not have a Belgian ID card yet

This is the most common situation for new arrivals, because the landlord wants the guarantee before you move in, and the commune registers you after you move in. Your options narrow:

• A surety such as garantie.be works with documents sent online and does not need a Belgian card, but ask the landlord first if the flat is in Flanders.
• A bank blocked account is still possible, but usually not online. Go to a branch with your passport, the signed lease and your residence documents, and ask whether they open a rental guarantee account for non-residents.
• If you will need a regional loan later, start the commune registration as soon as you have the address, since SWCS and the Vlaams Woningfonds require registration in the foreigners’ register.

You can also ask the landlord to accept a surety for now and a blocked account later. Any such arrangement depends on the landlord, so get it in writing in the lease or an annex.

If you rent in Brussels, Flanders or Wallonia

Brussels. The deposit is capped at two months for leases signed or renewed from 1 November 2024, and the Housing Code lists five forms, including a bank guarantee built up monthly over up to three years and a personal guarantee. Brussels Housing Code lists five forms: individual blocked account, CPAS bank guarantee, bank guarantee built up monthly over max 3 years, real security with a financial institution, personal guarantee. (source, checked 2 November 2026) The Brussels Housing Fund loan is the main help for modest incomes.

Flanders. Up to three months, and the tenant picks the form; a surety needs the landlord’s agreement. The Vlaams Woningfonds lends the deposit at no interest within income limits, and the OCMW can arrange a bank guarantee. See the decree on the Vlaamse Codex.

Wallonia. Two months maximum since 1 June 2023, whatever the form, as set out in the Walloon decree on Wallex (checked 2 November 2026). Some bank pages still mention three months for Wallonia; the decree is what applies. The SWCS loan covers flats and student rooms. The list of accepted forms in Wallonia was not part of the sources checked for this guide, so confirm on the Walloon housing site whether a surety company is accepted before relying on one there.

If you cannot pay the deposit upfront

Look at the public options before a paid surety, because they cost nothing in interest:

1. In Brussels, the Housing Fund loan, or BRU-GAL if your resources are very low.
2. In Wallonia, the SWCS loan.
3. In Flanders, the Vlaams Woningfonds loan.
4. Everywhere, a bank guarantee through your CPAS/OCMW.

All of them check income and most need registration at the commune, so they take longer than a commercial surety. If the move-in date is close, ask the landlord whether the keys can be handed over once the loan is approved, with the approval letter as proof.

Step by step: lodging a blocked rental guarantee

1. Check the lease: amount, form of guarantee and region. Compare the amount with the regional cap.
2. Choose the institution. With a Belgian ID card you can often open online; without one, book a branch appointment.
3. Bring or upload: your ID or passport, the signed lease, the landlord’s details and the property address.
4. Transfer the deposit into the new blocked account from your own account.
5. Send the confirmation to the landlord or agency. They usually hand over the keys once they have it.
6. Keep the entry inspection report, photos and the guarantee confirmation together.
7. At the end of the lease, after the exit inspection, sign the release form with the landlord. If you disagree on damage, the money stays blocked until you agree or a court decides.

Our verdict

For most newcomers who already have a Belgian ID card and the cash, the KBC blocked account is the best pick: it costs nothing to open, the money stays yours and earns interest, and every landlord in every region has to accept it. If you do not have the card yet or need your savings for the first months, garantie.be is the practical alternative, as long as you accept a yearly fee you never get back and, in Flanders, the landlord agrees. If paying upfront is the real problem, go to the public schemes of your region: the Brussels Housing Fund, SWCS in Wallonia or the Vlaams Woningfonds, with the CPAS/OCMW as a last resort. e-DEPO and Korfine are legal options, but unverified details for one and the lack of deposit protection and English documents for the other make them weaker choices for a new arrival.
