Renting in Brussels: leases, deposits and notice periods

Why this is different from renting in the UK

In Brussels, housing is a regional competence, so your tenancy is governed by the Brussels Housing Code rather than by whatever the letting agent puts in front of you. Notice periods, exit indemnities, deposit limits and rent increases are all set by law, and a clause in your contract that contradicts them generally cannot be enforced against you. The most common mistake UK arrivals make is assuming the contract is the last word. It isn't.

The three lease types

Almost every residential tenancy in Brussels falls into one of three categories, and which one you sign determines how easily you can leave.

Lease type	Can you leave early?	Notice	Indemnity
Long lease — nine years, the default for a main residence	Yes, at any time, without giving a reason	3 months	3 months' rent in year 1, 2 months in year 2, 1 month in year 3, nothing from year 4
Short lease — six months to three years	Yes, at any time	3 months	1 month's rent
Very short lease — under six months	No — it ends automatically at the agreed date unless extended	None	Not applicable

Two details catch people out. First, the notice period runs from the first day of the month following the month in which you give notice, so notice given on 20 October starts on 1 November and expires at the end of January. Second, the indemnity is a fixed statutory compensation, not a loss-based claim — your landlord does not have to prove they lost any money, and the fact that a new tenant has already moved in makes no legal difference (Commissioner Brussels).

The deposit: two months, and not in the landlord's account

The rental guarantee is capped, and the cap depends on the form it takes (Commissioner Brussels, citing Articles 248–249 of the Brussels Housing Code):

Form of guarantee	Maximum	How it works
Blocked bank account in your name	2 months' rent	You and the landlord jointly sign to open it. The money stays your property and the interest accrues to you. Neither party can touch it alone.
Bank guarantee	3 months' rent	The bank stands as guarantor and you repay it by monthly transfer over a maximum of three years. Useful if you can't put two months' rent down at once.
e-DEPO via MyMinfin	Same limits apply	The state-run online alternative to a blocked account. Access needs a chipped residence permit or a digital key, so it's usually only available once you're registered.

Never pay the deposit in cash or by transfer into the landlord's own current account. If you do, the law treats it as settlement of a debt rather than a guarantee, and you lose your claim to it entirely if the landlord becomes insolvent. If cash is genuinely unavoidable, insist on a signed receipt in as many copies as there are parties.

At the end of the tenancy the deposit must be released within two months of you handing back the keys. If the landlord misses that deadline, they become liable for an amount equal to 10% of the rent per month. Release normally requires a signed agreement between you and the landlord after the lease has ended; where you can't agree, the Justice of the Peace for the district can order it released.

Lease registration is the landlord's job — and your leverage

Registration is compulsory. The landlord must register the lease, its signed annexes and the entry inventory within two months of signing, must give you proof of registration, and pays for it — registration is free where the property is used exclusively as housing (Brussels-Capital Region, FPS Finance). Since 1 January 2025 a Brussels residential lease must be registered with both FPS Finance and the Brussels-Capital Region.

This is worth knowing for two reasons. A registered lease is enforceable against third parties, which protects you if the property is sold during your tenancy — the buyer inherits your lease rather than being free to remove you. And if the landlord doesn't register it, you may terminate the lease without notice and without paying any indemnity. If your landlord has been vague about registration and you want out, check this first.

The inventory of fixtures decides your deposit back

An état des lieux (inventory of fixtures) is mandatory and must be drawn up before you move in or within the first month of the lease. After that first month, neither side can compel the other to do one, because the property is already occupied — which in practice means a missing inventory becomes your landlord's problem rather than yours (Brussels-Capital Region).

• It is preferably done by an independent expert, with the fee shared between the two parties, or jointly by tenant and landlord.
• If one party ignores the other's request to do one, the other can ask the Justice of the Peace to appoint an expert.
• An exit inventory should be carried out after you move out, within a month, and before you hand back the keys. That order matters — keys last.
• You must return the property as you received it, excluding normal wear and tear, ageing and construction defects.
• Where no entry inventory was carried out, the burden of proving damage falls on the landlord.

Photograph everything on the day you get the keys, date-stamped, and log every existing mark in the inventory itself however petty it feels. This single hour of work is what decides whether two months' rent comes back to you.

Rent increases: once a year, and not automatic

Your landlord cannot simply raise the rent. Indexation is permitted only if the lease doesn't exclude it and the landlord has met their regional obligations — registering the lease and giving you an energy performance certificate (EPB) for the property (Brussels-Capital Region). Beyond that:

• Rent may be adjusted once a year at the earliest, on the anniversary of the lease taking effect.
• It is not automatic — the landlord has to request it from you in writing.
• A late request is only retroactive for the three months before the month in which it's made, so a landlord who forgets for two years cannot bill you for the backlog.
• The calculation is fixed by Article 1728bis of the old Civil Code: base rent × new health index ÷ initial health index. The initial index is the month before signing; the new index is the month before the anniversary date.
• For leases that took effect before 14 October 2022 on properties rated E, F or G on the EPB certificate, a correction factor must be applied to the formula.

If you get an indexation request, check the arithmetic against the published health index rather than accepting the figure. Errors in the landlord's favour are common.

Minimum standards the property must meet

A rental property in Brussels must meet minimum requirements for safety, sanitation and basic facilities, and the landlord must ensure this both at the start of and throughout the tenancy. Properties that fail can be banned from being let at all (Brussels-Capital Region). Damp, unsafe wiring and inadequate heating are not things you simply have to live with because you signed.

A short checklist before you sign

1. Confirm in writing which lease type you're being offered — nine-year, short, or very short. It changes your exit terms completely.
2. Agree the deposit form before you transfer anything, and use a blocked account or e-DEPO. Not the landlord's account.
3. Get the EPB certificate at signing. Without it, future indexation is on shaky ground.
4. Book the entry inventory for the day you take the keys, and take your own dated photographs regardless.
5. Ask for the proof of registration and diarise the two-month deadline.
6. Keep every letter and email. Almost every dispute here is won on documentation rather than argument.
