Security Deposits in Luxembourg: The 2026 Rules Every Tenant Should Know

If you are renting a room or an apartment in Luxembourg, the deposit is usually the single largest sum you hand over before you have even collected the keys. The rules changed significantly in 2024, and a lot of the advice still circulating online, including on landlord and expat forums, is out of date.

The legal cap: two months, not three

Luxembourg's residential lease law was reformed by the law of 23 July 2024, which came into force on 1 August 2024. It was the most significant overhaul of tenant and landlord rules in nearly two decades, and one of its headline measures was a reduction of the maximum rental deposit from three months' rent to two months.

The reform applies to every residential lease signed on or after 1 August 2024. A landlord who asks for more than two months is acting outside the law, and the excess is not enforceable even if you agreed to it in writing and signed willingly. In a market where good rooms disappear in days, tenants often accept conditions they know are unusual simply to secure a place. That pressure does not change what the law allows.

Leases signed before August 2024 were not cancelled or rewritten by the reform, and remain valid on their original terms. If you signed earlier and paid three months, however, you are entitled to ask your landlord in writing to adjust the guarantee down to the new ceiling.

Why "base rent" matters

The two-month cap is calculated on the base rent, charges excluded. That distinction is worth understanding, because it is where most disagreements start.

In Luxembourg, a rental price is usually quoted in two parts: the rent itself (loyer) and the monthly charges (charges), which cover things like heating, water, building maintenance and shared electricity. Only the first figure counts towards the deposit calculation.

A worked example. Base rent of €1,500 per month with €200 of monthly charges gives a maximum legal deposit of €3,000. Not €3,400. The charges never enter the calculation, whatever the contract says.

Ask for the split in writing before you sign anything. A listing that quotes only an "all-in" figure is not necessarily suspicious, but you need the breakdown to check both the deposit and your real monthly cost.

Four ways to provide the deposit

Luxembourg does not require you to hand over cash. Several instruments are accepted, and the right one depends on how much liquidity you want to keep available.

Blocked bank account (compte bloqué)

The most common route. You and the landlord open a joint blocked account and neither party can withdraw unilaterally. The funds are visibly ring-fenced, which removes most of the ambiguity at the end of the lease. This is generally the cleanest option for both sides.

Bank guarantee (garantie bancaire)

Your bank issues a guarantee letter to the landlord while the money stays in your own account, earmarked rather than transferred. Banks usually charge a fee for this. It is a popular option for people arriving from abroad who would rather not move a large sum immediately after opening a local account.

State-backed guarantee

Luxembourg operates a scheme under which the State acts as guarantor for tenants who meet eligibility conditions. It exists precisely because the upfront cost of renting is the main barrier for people on modest incomes, and it is worth checking before you assume a deposit is unaffordable.

Cash or transfer directly to the landlord

Legal, but the weakest position to be in if a dispute arises later. If you go this route, insist on a dated, signed receipt that states the amount and describes it explicitly as a rental guarantee rather than a payment.

The inventory that protects your money

The 2024 reform made the entry inventory, the état des lieux d'entrée, mandatory. This matters more than most tenants realise: without a documented entry inventory, a landlord cannot withhold your deposit for damage.

The inventory is the baseline against which the property is judged when you leave. Do it properly and it becomes the strongest document you hold.

  • Walk the property with the landlord or agent and record the condition of every room, not just the obvious areas.
  • Photograph anything already marked, scratched, stained or broken, and make sure the photographs carry a date.
  • Note appliance condition and meter readings for electricity, gas and water.
  • Check that the written document reflects what you saw before you sign it, and keep your own copy.

Normal wear and tear is not damage. Faded paint after three years, minor marks on a wall, a worn patch of flooring in a hallway: these are expected consequences of somebody living in a home, and they are not deductible.

How and when the deposit must come back

Before 2024, the law was vague about timing, and deposits routinely sat unreturned for months. The reform introduced a structured, two-stage return process with binding deadlines and penalties for landlords who miss them without justification.

StageWhat must happen
First halfReturned within one month of the exit inventory
Second halfReturned within one month of the final statement of charges and utilities

The logic behind the split is straightforward. The first tranche settles the physical condition of the property, which is known immediately at check-out. The second waits for the annual reconciliation of utilities, because until the building's accounts are closed nobody knows whether your provisional charges covered your actual consumption.

If the landlord withholds any part of the deposit, they must justify it in writing, identify the specific damage, and support the figure with a quote or an invoice. A round number with no documentation behind it is not a valid deduction.

If the money does not arrive

Start with a written request. A dated letter or email restating the deadline, the amount and the absence of any documented deduction resolves a large share of cases on its own, because it makes clear that you know the rules.

If that fails, Luxembourg provides a free conciliation route at commune level, through the local rental conciliation body. It is designed to settle landlord and tenant disputes without going to court, and it costs nothing, but it works far better when you arrive with the entry inventory, the exit inventory, the lease and your written correspondence in hand. Documentation is what decides these cases.

For the official procedure and the current forms, guichet.lu is the authoritative public source, and your commune's housing service can point you to the right body.

How this works for a room in a shared flat

The rules are the same when you rent a single room under a written contract, which is how most of our rental listings are structured. The deposit is calculated on the base rent of your room, not the whole apartment, and the same two-month ceiling applies.

What changes in a shared home is the practical side. Your inventory should cover your own room in detail and note the condition of the shared kitchen and bathroom, because that is where responsibility gets blurred at the end of a tenancy. If three people share a kitchen and one of them damages a worktop, an inventory naming the pre-existing condition is what stops the cost being split across everyone.

Across the rooms we manage in Bonnevoie, Limpertsberg and Rollingergrund, the deposit is typically set at one month's rent rather than the legal maximum of two, and it is always stated on the listing page before you contact us. We would rather you knew the total cost of moving in before the viewing than discover it afterwards.

Before you sign

Three things are worth checking on every rental in Luxembourg, whatever the property. The lease must be in writing, a requirement since August 2024. The deposit must not exceed two months of base rent. And the entry inventory must be completed and signed, because without it the deposit cannot lawfully be withheld against damage.

None of this is difficult, but it is easier to insist on at the start than to reconstruct at the end. If you are weighing up a room and want the deposit, charges and contract terms laid out clearly before you commit, talk to us and we will put it in writing.
