In Belgium, a rental guarantee is typically equivalent to two or three months of rent, depending on the type of rental agreement and how the guarantee is provided. For most standard residential rentals, the amount is capped at two months of rent when paid in cash. This article unpacks the key questions expats and international professionals commonly have about rental deposits in Belgium.
How much is a rental guarantee in Belgium?
The amount of a rental guarantee in Belgium is generally capped at two months of rent when the tenant pays the deposit directly into a blocked bank account. If the guarantee is provided through a bank guarantee, the cap is typically three months of rent. The exact amount can depend on the type of rental contract and the arrangement agreed upon between tenant and landlord.
For expats and international professionals arriving in Belgium, this distinction matters in practice. Paying two months of rent upfront as a cash deposit is the most common approach for private tenants. A bank guarantee, on the other hand, allows the tenant to have the bank commit the amount without actually transferring the funds immediately, which can be useful if liquidity is a concern at the start of a new assignment.
It is worth noting that the rental guarantee is separate from the first month’s rent and any service or agency fees. When budgeting for a move to Belgium, international professionals should factor in the deposit on top of their other initial housing costs.
What are the different types of rental guarantee in Belgium?
There are three main ways a rental guarantee can be arranged in Belgium: a cash deposit into a blocked bank account, a bank guarantee, or a guarantee provided by a social fund or public institution. The first two are by far the most common in the private rental market.
- Blocked bank account: The tenant deposits the agreed amount into a dedicated account in their own name. The funds are blocked until the end of the rental period and can only be released with the agreement of both parties or following a formal dispute resolution process.
- Bank guarantee: The bank commits to covering the deposit amount on behalf of the tenant. The tenant does not transfer funds upfront, but the bank holds the guarantee in reserve. This option is often linked to a personal bank loan arrangement.
- Social or institutional guarantee: In specific circumstances, a public social service or CPAS (public social welfare centre) can act as guarantor. This option is generally intended for tenants in more vulnerable financial situations and is less relevant for most international professionals.
For expats relocating to Belgium for work, the blocked bank account is usually the most straightforward path, provided they already have a Belgian bank account. Opening a bank account as a new arrival can take some time, so it is advisable to start this process early in the relocation process.
Does a rental guarantee in Belgium earn interest?
Yes, a rental guarantee held in a blocked bank account in Belgium does earn interest. The interest accumulates over the duration of the rental period and is paid out together with the deposit at the end of the tenancy. In most cases, the interest goes to the tenant, since the funds technically remain the tenant’s property throughout the rental period.
In the current low-to-moderate interest rate environment, the interest earned on a rental guarantee is unlikely to be a significant sum, particularly for shorter rental periods. That said, it is a detail worth being aware of, especially for professionals on longer assignments who may have their deposit blocked for several years.
For bank guarantees, the interest dynamics are different since no funds are actually deposited. In that case, the tenant may pay a fee to the bank for providing the guarantee, which effectively offsets any interest benefit.
When is the rental guarantee returned in Belgium?
The rental guarantee is typically returned at the end of the tenancy, once both the tenant and landlord have agreed on the condition of the property. If there are no disputes about damages or unpaid rent, the full deposit amount plus any accrued interest is released to the tenant. In practice, this process often takes a few weeks after the keys are handed back.
The return of the deposit depends on a smooth end-of-tenancy inspection. A detailed inventory drawn up at the start of the rental period plays an important role here. It serves as the reference point for assessing whether any damage has occurred beyond normal wear and tear.
If there is a disagreement between tenant and landlord about deductions from the deposit, the funds remain blocked until the dispute is resolved. This can be done through mutual agreement, mediation, or a formal legal process. To avoid complications, it is advisable to document the condition of the property thoroughly at both move-in and move-out.
Can a landlord ask for extra guarantees beyond the deposit?
In some situations, landlords may request additional assurances beyond the standard rental deposit. This can occur when a tenant has no rental history in Belgium, no local income documentation, or when the rental is for a high-value property. However, what is considered acceptable or standard practice can vary, and tenants are not always obliged to accept additional requirements.
Common forms of additional assurance that landlords may informally request include:
- A letter of guarantee from an employer confirming the tenant’s employment and salary
- Recent payslips or proof of income
- A reference letter from a previous landlord
- A co-signer or guarantor based in Belgium
For expats and international professionals, providing an employer letter is often the most practical option. Many international organisations, multinationals, and embassies routinely issue such letters for their relocating staff. If you are moving to Belgium through a company or institution, it is worth asking your HR or relocation contact whether they can provide supporting documentation.
What happens to the rental guarantee if the property is sold?
If the property you are renting is sold while you are still a tenant, the rental guarantee is not affected in terms of its purpose or your rights as a tenant. The deposit remains blocked in the account or held by the bank, and the new owner takes over the role of landlord, including the obligation to return the guarantee at the end of the tenancy under the same conditions.
In practice, a change of ownership should not disrupt your tenancy. Your rental contract generally continues under the same terms, and the guarantee arrangement transfers along with the property. That said, it is sensible to keep clear records of your deposit confirmation and any correspondence related to the guarantee, so there is no ambiguity if ownership changes hands.
If you have any concerns about how a property sale might affect your tenancy or deposit, consulting a professional adviser with experience in Belgian rental matters is a practical step.

Frequently Asked Questions
Can I use a foreign bank account to pay a rental guarantee in Belgium?
Generally, no. Belgian landlords typically require the rental guarantee to be held in a Belgian blocked bank account, which means you will need a local bank account before you can finalise your rental agreement. Opening a Belgian bank account as a new arrival can take anywhere from a few days to a few weeks depending on the bank and your documentation, so it is strongly advisable to initiate this process before or immediately upon arrival. Some relocation services and employers can help facilitate this step.
What documents do I need to set up a blocked bank account for my rental guarantee?
To open a blocked bank account for your rental guarantee in Belgium, you will typically need a valid passport or national ID, proof of your Belgian address (or a temporary address confirmation), your rental contract, and in some cases your Belgian national registration number (NN). Requirements can vary between banks, so it is worth contacting your chosen bank in advance to confirm exactly what they need. Some banks also offer dedicated services for expats and international arrivals, which can simplify the process.
What counts as 'normal wear and tear' versus damage when the deposit is assessed at the end of a tenancy?
Normal wear and tear refers to the gradual, expected deterioration of a property through everyday use — for example, minor scuffs on walls, slight fading of paint, or carpet wear in high-traffic areas. Damage, by contrast, includes things like large holes in walls, broken fixtures, stained flooring, or missing items that were present at move-in. The distinction is assessed against the move-in inventory, which is why having a detailed, signed inventory at the start of your tenancy is so important. When in doubt, documenting everything with dated photographs at both move-in and move-out provides the clearest protection.
What should I do if my landlord refuses to return my deposit after I move out?
If your landlord is withholding your deposit without a clear, justified reason, the first step is to communicate in writing, requesting a formal explanation of any deductions. If no agreement can be reached, you can contact a local mediation service or the Justice of the Peace (Justice de Paix / Vredegerecht), which handles residential tenancy disputes in Belgium. Since the funds in a blocked bank account can only be released with the agreement of both parties or a court order, the legal process does provide a structured path to resolution. Keeping all documentation — your rental contract, inventory, correspondence, and move-out photos — will significantly strengthen your position.
Is a rental guarantee required for all types of rental agreements in Belgium, including short-term or serviced apartments?
Not necessarily. The standard rental guarantee rules apply primarily to standard residential lease agreements governed by Belgian regional housing legislation. Short-term rentals, serviced apartments, and furnished accommodation provided under different contractual frameworks — such as those offered by providers like RentMore — may operate under different terms, and a traditional blocked-account deposit may not always be required. It is always worth clarifying the deposit and payment structure directly with your housing provider before signing, so you know exactly what financial commitments are involved upfront.
Can my employer pay the rental guarantee on my behalf?
In principle, the rental guarantee is the tenant’s financial responsibility, but some employers — particularly multinationals and international organisations — do assist relocating employees with housing costs, which can include the deposit. This is typically handled through an expense reimbursement or as part of a broader relocation package rather than the employer paying directly into the blocked account. If your company is supporting your move to Belgium, it is worth discussing this with your HR or mobility team early in the process to understand what financial assistance is available and how it is structured.
How far in advance should I start arranging my rental guarantee before my move-in date?
Ideally, you should start the process at least four to six weeks before your intended move-in date. This gives you enough time to open a Belgian bank account if you do not already have one, gather any required documentation, and transfer funds without last-minute pressure. Delays in banking setup are one of the most common practical hurdles for new arrivals in Belgium, and they can hold up the signing of your rental contract if not addressed early. If your timeline is tight, ask your employer, relocation contact, or housing provider whether they can recommend banks or services that specialise in fast-tracking accounts for international professionals.
