Understanding your Luxembourg rental contract before you sign

Does a rental contract have to be in writing in Luxembourg?

Yes. Since the reform that took effect on 1 August 2024, every residential lease must be made in writing and must contain a set of mandatory provisions. A verbal arrangement, or a one-page note about the rent, is no longer sufficient.

This is good news for tenants, and it is also the reason to read what you are given rather than assume it is standard. A lease produced from an old template may simply be missing things the law now expects.

What must be in the contract

A written residential lease has to specify:

If any of these is missing, ask for it to be added before signing rather than after. A landlord using a compliant template will not mind; one who resists is telling you something.

Note the last line in particular. The contract itself has to tell you that a rent dispute can be taken to the Rent Committee — the commission des loyers — which is the body that deals with disagreements about the rent amount.

How long the lease runs, and what happens at the end

The parties are free to agree a fixed term or an open-ended arrangement. Fixed terms are the norm, typically one, two or three years.

The part that surprises people is what happens when a fixed term expires: the lease renews automatically. It does not quietly lapse and leave you to move out, and equally it does not leave the landlord free to treat you as a guest.

To stop a renewal, one side has to say so expressly and respect the notice period. In practice this means a fixed-term lease behaves less like a countdown and more like a rolling arrangement that either side can step out of by giving proper notice.

Notice periods

Notice is 3 or 6 months, or longer where the contract says so. Which one applies to you is in the lease, which is exactly why the term and the notice clause are worth reading before you sign rather than eleven months later.

Two practical points:

• Give notice in writing, and in a form that proves it arrived. Registered post is the standard.
• Count backwards from the date you want to leave, not forwards from today. A six-month notice period on a flat you hoped to leave in April means writing in October.

Where several people share a lease, a cotenant leaving early gives three months' notice to the landlord and the other cotenants, and is expected to look for a replacement.

Rent: how it is set and when it can change

Rent in Luxembourg is not a free negotiation. The maximum annual rent may not exceed 5% of the capital the landlord invested in the property.

Once set, rent may be reviewed once every two years, and may not rise by more than 10%. A lease clause promising an annual increase, or an increase tied to an index without regard to those limits, is worth questioning.

The reform also abolished the "luxury housing" category, which had allowed some properties to escape the rent cap. If a landlord suggests the cap does not apply because the property is high-end, that exemption no longer exists.

Charges: advances, flat rates, and the annual statement

Charges (charges locatives) are your running costs — heating, water, communal areas, and similar. The lease must say whether you pay:

• an advance, reconciled later against real costs; or
• a flat rate, fixed and not reconciled.

With an advance, the landlord may ask for reasonable instalments and may adjust them based on what the charges actually came to in previous years. Crucially, they must send you an annual breakdown of the charges, with the receipts and invoices behind it, showing what you paid monthly against what was actually spent.

That annual statement is your protection. If you have never seen one, ask — it is not optional, and a charges account nobody ever reconciles has a way of drifting upward.

A flat rate is simpler and removes the year-end surprise in both directions. It is legitimate where it genuinely covers normal consumption, and it can be adjusted during the lease.

Furnished lettings

A furnished property may carry a surcharge for the furniture, and that surcharge must appear in the contract as its own line rather than being folded invisibly into the rent. If you are told a flat is furnished and the lease says nothing about furniture, something is missing.

It is worth attaching an inventory of the furniture itself, separate from the inventory of the property's condition. Which sofa, which appliances, what state they are in.

Clauses worth questioning

Not everything in a lease is enforceable simply because it is printed. Pause on:

• A deposit above two months' rent. The ceiling is two.
• The tenant paying the whole agency commission. It is shared equally.
• Automatic annual rent increases that ignore the two-year and 10% limits.
• A blanket obligation to repaint or professionally clean on departure, regardless of the state you leave the property in. Normal wear is the landlord's cost.
• A clause preventing you from contesting the rent. The contract must actually tell you the Rent Committee exists.
• Vague charges. "Charges: to be determined" is not an amount.

Raising these before signing is normal and reasonable. You are not being difficult; you are reading a contract.

The inventory belongs with the contract

The inventory of fixtures — the état des lieux — is completed jointly by landlord and tenant, and it is what decides later whether a mark on the wall is wear or damage. Do it before your furniture arrives, name defects specifically, and keep your copy.

A lease that mentions no inventory at all is a lease that will be argued about when you leave.

Frequently asked questions

Can the landlord change the rent during the lease? Only within the rules: once every two years, and by no more than 10%. A change outside those limits is contestable, and the Rent Committee exists for exactly this.

What if my landlord will not put it in writing? Written form is a legal requirement for residential leases. A landlord unwilling to produce a written contract is not offering you a normal tenancy.

My fixed term ends next month and nobody has said anything. Do I have to leave? No. Fixed-term leases renew automatically unless one side gives proper notice.

Can I leave earlier than the notice period if I find a replacement? That is a matter for agreement with the landlord, except in a colocation, where the framework provides for it directly. Get any agreement in writing.

Who pays for repairs? Broadly, the landlord maintains the property and the tenant handles small routine upkeep. Anything the lease claims beyond that is worth reading closely.
