How to Rent Out a Room in Belgium Without Fines: Lease Registration, EPC and Taxes
Mandatory lease registration, the EPC certificate, and how a furnished room is taxed in Belgium — what every landlord needs before listing.

At Roomie-Radar we regularly get the same message from tenants who just found a room: "the lease asks for tenant insurance, is that actually mandatory?" The short answer is no, no Luxembourg law requires it, but that answer alone is incomplete, and taking it at face value can leave you signing a lease without coverage you will very likely need.
Not by law. There is no Luxembourg regulation forcing a tenant to take out liability insurance for tenants (assurance responsabilité civile locative). However, the vast majority of lease contracts include a clause requiring it anyway, and landlords typically ask for proof of insurance at key handover, then again every year at renewal.
In practice, this turns a "non-legal" requirement into a near-universal condition for renting. If your lease includes that clause and you don't provide proof, the landlord can refuse to hand over the keys, or, if you're already living there, start proceedings to terminate the contract.
It covers damage that you, as the tenant, cause to the rented property: fire, water damage, and in many policies your own personal belongings (clothing, electronics, furniture). The landlord has their own insurance on the building, but that policy doesn't cover damage you're responsible for as the occupant, which is exactly why you need your own.
Here's the detail that catches most new tenants off guard: Article 1733 of the Civil Code presumes the tenant liable in the event of a fire. That means if a fire breaks out in the property you're renting, you're automatically presumed responsible unless you can prove the cause was unrelated to you (a building-wide electrical fault not connected to your use, for example). Without insurance, that liability falls directly on your personal finances.
The typical range sits between €200 and €400 a year, depending on the value of your belongings, the size of the property, and the insurer. There's no fixed price because each policy is priced against what you declare, but that range covers most individual contracts for a room or a small flat.
It's worth reviewing the policy every year or two: if you buy new equipment, change rooms, or your situation changes, the insured amount should reflect that.
You become personally liable, out of your own pocket, for the damage caused, even if the fire started while you were out. Without proof of insurance, the landlord can also refuse to let you move in at signing, or start termination proceedings if the lease is already underway.
This is different from Belgium, where tenant insurance is a direct legal obligation, not just a contractual one, which we cover in detail in renting in Brussels as an expat. If you're comparing the two markets, the difference isn't cosmetic: in Luxembourg the pressure comes from the contract and Article 1733, not from an insurance law as such.
It depends on how the contract is structured. If each tenant has an individual contract (common in verified coliving), each one needs their own policy covering their room and the agreed use of common areas. If all tenants sign a single joint contract with the landlord, it's often enough for at least one flatmate to be insured to satisfy the landlord's requirement, though it's worth clarifying this in writing before signing, since joint liability can get complicated if something breaks in a common area and only one person holds a policy.
If you're renting, check your contract before signing: the insurance clause is usually on the first few pages, next to the deposit terms, which we cover in detail in the rental deposit in Luxembourg. Many of our landlord users tell us that asking for proof of insurance at signing, rather than later, avoids misunderstandings that otherwise surface months down the line. Roomie-Radar connects landlords with qualified users searching for a room in Luxembourg, and using Roomie-Radar is free.
Tenant insurance in Luxembourg isn't mandatory by law, but treating it as optional is an expensive mistake: almost every lease requires it anyway, and Article 1733 of the Civil Code presumes you liable in the event of a fire unless you can prove otherwise. Between €200 and €400 a year is a low cost against the real risk of covering a fire or water damage entirely out of pocket.
If you're searching for a room in Luxembourg, check the insurance clause before signing and have proof ready on move-in day. At Roomie-Radar we list verified rooms and help the process start with clear information from the outset. Start at roomie-radar.com.
1. Is tenant insurance mandatory in Luxembourg?
Not by law, but the vast majority of lease contracts include a clause requiring it. In practice, it functions as a near-universal requirement for renting, even without a general legal obligation.
2. What if my lease doesn't mention insurance?
If your lease doesn't include the clause, you're not legally required to take it out. It's still advisable, though, because Article 1733 of the Civil Code presumes you liable in the event of a fire whether or not your contract has a specific clause.
3. How much does tenant insurance cost in Luxembourg?
The typical range is between €200 and €400 a year for an individual room or small flat contract, depending on the value of your belongings and the insurer chosen.
4. What exactly does tenant liability insurance cover?
It covers damage you cause to the rented property, mainly fire and water damage, and in many policies your own personal belongings too. It doesn't cover the building itself, which is insured by the landlord.
5. What happens if there's a fire and I don't have insurance?
You're personally liable for the damage, since Article 1733 of the Civil Code presumes you responsible unless proven otherwise. Without insurance, that cost falls directly on your own finances.
6. Do I need tenant insurance if I live in a colocation in Luxembourg?
Yes, though how it's arranged depends on the contract. With individual contracts, each tenant needs their own policy. With a joint contract, it's often enough for one flatmate to be insured, but it's worth clarifying this in writing before signing.
7. Can the landlord refuse to give me the keys if I don't have insurance?
Yes, if your lease includes the insurance clause and you don't provide proof, the landlord can refuse to hand over the keys or start termination proceedings if the lease is already underway.
8. Is it the same as in Belgium?
No. In Belgium tenant insurance is a direct legal requirement, not just a contractual one. In Luxembourg the requirement comes from the contract and the Article 1733 presumption, not from a specific insurance law.
9. How often should I review my tenant insurance policy?
It's recommended to review it every year or two, especially if you buy valuable items, change rooms, or your personal situation changes, so the insured amount keeps reflecting reality.
10. Does Roomie-Radar require tenant insurance from renters?
No. Roomie-Radar connects landlords with qualified users searching for a room in Luxembourg, but the insurance requirement depends on the contract signed directly between landlord and tenant.
