What does fibre eligibility mean in Luxembourg?
Being eligible for fibre optic means your home can be physically connected to the very high-speed network of at least one internet provider. Two conditions must be met simultaneously: the fibre infrastructure has been deployed near your home by POST Technologies (the main infrastructure operator), AND at least one commercial operator has activated its services at your specific address.
Fibre infrastructure has been deployed near your home
POST Technologies has run fibre optic cables in your street or neighbourhood. An Optical Distribution Point (PBO) must be accessible near your building. Without this physical infrastructure, no operator can connect you.
At least one commercial operator offers services at your address
The physical network alone is not enough — a commercial operator (POST, Tango, Orange, Luxembourg Online) must have activated its service on your zone. Once your street is connected, all operators with an access agreement can in principle sell you a subscription. This competition is regulated by the ILR (Institut Luxembourgeois de Régulation).
The ILR considers a building « connected to fibre » when fibre is already available or will be available within a maximum of four weeks. If your address appears as covered on the ILR map (myilr.lu), you can expect to be connectable very soon.
As of end 2024, 16.2% of Luxembourg households were not yet covered by fibre. POST Technologies is actively deploying the network towards 100% national coverage, with investment levels at a historic high (+73% in 2024 per ILR).

How to test your fibre eligibility in Luxembourg
Method 1 — Switchr eligibility test (recommended)
Fill in the form above with your full address and contact details. A partner operator calls you back to confirm your eligibility address by address, present the available offers, and schedule installation if you wish. The service is 100% free with no commitment.
Method 2 — Official ILR map (myilr.lu)
The ILR provides an interactive coverage map at myilr.lu, showing fixed and mobile network availability by address, technology (FTTH fibre, DOCSIS cable, xDSL, 4G, 5G) and infrastructure operator. This is the official reference source, freely accessible.
Method 3 — Operator websites
POST Technologies at posttechnologies.lu, Orange Luxembourg at orange.lu, Tango at tango.lu, Luxembourg Online at internet.lu or by calling 2799 0000. These operator-specific checks tell you whether that particular operator can commercially serve your address.
Method 4 — Physical check in your building
If you live in an apartment, check the basement or parking area for a fibre distribution cabinet (a white or grey box with thin optical cables, labelled POST Technologies or Eltrona). Its presence confirms your building is connected or being connected to fibre. In a house, an ONT (optical box) on the wall confirms an existing connection.
POST connection number: if your building is already connected to the POST Technologies network, a sticker on the ONT (optical box) shows a connection number in the format 169XXXXXX or 612XXXXXX. Share this number with your chosen operator when subscribing — it speeds up your line activation.

Test my addressFibre eligibility in an apartment in Luxembourg
If your building is already connected to fibre, simply choose your operator and subscribe — the technician connects your apartment to the existing distribution point (PBO). If your building is not yet connected but fibre is available in the street, the process depends on your situation.
You are a tenant
You must obtain written authorisation from your landlord before any installation involving works in the property or common areas. In a co-ownership building, the property manager (syndic) must also agree — the matter can be added to the agenda of a General Assembly. Luxembourg law (17 December 2021 on electronic communications networks) facilitates these decisions by subjecting such works to a simple majority vote rather than a reinforced majority.
You are an owner-occupier
In a co-ownership not yet connected, you can submit a connection request to the General Assembly agenda (simple majority vote required), or contact an operator directly to equip the building. Once the building is connected, you subscribe with the operator of your choice.
If you are in a building not yet connected, plan well ahead. Between the General Assembly agenda submission, the assembly itself, the operator agreement and the actual works, several months can pass. In the meantime, an Eltrona cable or fixed 5G solution can connect you immediately — see our guide on cable internet in Luxembourg.
Fibre eligibility in a detached house in Luxembourg
If the fibre infrastructure is present in your street but your house is not yet connected, POST Technologies is responsible for the physical connection. You can submit an underground connection request at posttechnologies.lu. If existing conduits run from the street to your house, the technician uses them to pull the fibre cable — the fastest and lowest-cost option. If no conduits exist or they are damaged, POST Technologies provides a quote for the necessary works. Note that works required on your private property due to damaged conduits are at your expense as the property owner.
Building a new home in Luxembourg? Legislation requires all new buildings (building permit submitted after 31 December 2016) to include high-speed internal cabling infrastructure. In practice, virtually all new homes in Luxembourg are connected to fibre during construction — notify POST Technologies as early as possible to integrate the fibre connection into the works. For relocations, see our guide on internet when moving home in Luxembourg.

Subscription and installation after the test
Once your eligibility is confirmed: compare available offers at your address (speed, price, commitment, TV/mobile bundles, installation fees — including total cost over 24 months); subscribe online, by phone or in-store; receive a temporary 4G/5G router immediately (POST, Tango and Orange); schedule a technician visit (typically 1–4 weeks); and prepare the installation day — identify the ideal location for the ONT box (ideally in the living room near your devices), clear the space, and ensure you are present for the full intervention (1–3 hours for an apartment, half a day for a house). For a comparison of all current offers, see our internet prices in Luxembourg guide.

Frequently asked questions — fibre eligibility in Luxembourg
Can you live in a fibred street and still not be eligible for fibre?
Yes. Eligibility depends on two separate conditions: fibre infrastructure in your street (deployed by POST Technologies) AND commercial activation by at least one operator at your specific address. There can be a gap of a few weeks or months between infrastructure deployment and commercial activation. If you are in this situation, retest regularly — commercialisation typically opens fairly quickly after infrastructure is deployed.
Is the fibre eligibility test free and non-binding?
Yes, absolutely. Our Switchr eligibility test is entirely free with no commitment. Filling in the form does not constitute a subscription. The partner operator who calls you back presents available offers, but you remain completely free to subscribe or not. The official ILR verification tools (myilr.lu) and operator websites are also free.
Can I freely choose my fibre operator if my building is already connected?
In principle yes — once the fibre infrastructure is deployed in your building or street, all operators that have activated their commercialisation on your zone can sell you a subscription. The ILR-regulated unbundling mechanism ensures that alternative operators (Tango, Orange, Luxembourg Online) can access POST’s infrastructure. However, there may be a gap between POST’s availability and that of other operators — check eligibility operator by operator to be sure.
How long does it take to get connected after confirming eligibility?
If your address is already connected to fibre (ONT present or PBO accessible), installation is typically completed within 1–2 weeks of subscribing. If your building is not yet connected but the street is fibred, allow 2–4 weeks. For a detached house requiring specific works, timelines can be longer. Eltrona guarantees installation within 7 days for its cable offer. In all cases, POST, Tango and Orange provide a temporary 4G/5G router immediately upon signing.
Can my landlord refuse fibre installation in my rented apartment?
In Luxembourg, landlord authorisation is required for any installation involving works in the property or common areas. Luxembourg law (17 December 2021) facilitates these decisions by subjecting such works to a simple majority vote. In practice, if your building is already connected and no heavy works are required, authorisation is generally easy to obtain. If difficulties persist, the ILR offers a mediation service.
How do I switch fibre operator in Luxembourg?
Switching fibre operator in Luxembourg is straightforward and regulated by the ILR. You subscribe with the new operator, who handles the cancellation process with your current provider. There is generally no service interruption during the switch. Be mindful of early termination fees if you are still within a commitment period. For step-by-step guidance, see our guide to switching internet providers in Luxembourg.
