Cheap internet in Luxembourg: find the best deal in 2026
In Luxembourg, a €50/month subscription gives you access to 1 Gbit/s fibre optic — and some offers go even lower thanks to promotions. But the displayed monthly price doesn’t tell the whole story: installation fees, modem rental, activation charges and post-promotion prices can vary the real cost by hundreds of euros over 24 months. This guide ranks offers by real total cost over 24 months and explains how to pay as little as possible while keeping a fast connection.

Luxembourg internet market prices in 2026
Luxembourg has a reputation for expensive internet — partly due to the high cost of living and the historical near-monopoly of POST. However, the situation is evolving rapidly: according to the European Commission, fixed broadband prices dropped by an average of 5% in 2024 versus 2023, driven by growing competition from alternative operators. In 2026, a 1 Gbit/s fibre subscription costs around €50/month at most operators, with promotional offers going as low as €35–40/month for the first 12–24 months. The average Luxembourg subscriber actually spends €54.6/month on fixed internet (ILR 2024) — suggesting many are not shopping around enough.

Never compare prices based on advertising. The large prices displayed on operator websites are often promotional rates for 6–12 months before reverting to the base price. The only honest way to compare is to calculate the total cost over 24 months, including all fees.
Calculating the real 24-month total cost — the only honest method
24-month total cost =
(Monthly rate during promo × months in promo)
+ (Base monthly rate × remaining months to 24)
+ Modem rental × 24
+ Installation fee (one-off)
+ Activation fee (one-off)
− Any cashback or rebates
| Item | Offer A — « €49/month » (6 months promo) | Offer B — « €39/month » (24 months, free installation) |
|---|---|---|
| Rate during promo | €49/month × 6 months = €294 | €39/month × 24 months = €936 |
| Rate after promo | €69/month × 18 months = €1,242 | — (fixed rate for 24 months) |
| Modem rental | €5/month × 24 = €120 | €5/month × 24 = €120 |
| Installation fee | €0 (included) | €0 (included) |
| Activation fee | €49 | €0 (included) |
| TOTAL OVER 24 MONTHS | €1,705 | €1,056 |
Illustrative example based on real pricing structures observed on the Luxembourg market. Prices and conditions vary by operator and period. Always verify exact conditions on our Luxembourg internet comparator.
Always verify the monthly price after the promotional period. An offer at €35/month for 6 months then €70/month for 18 months costs €1,470 over 24 months. An offer at €50/month fixed for 24 months costs €1,200 — €270 less for the same service. This is the most common trap on the Luxembourg telecom market.
Offers ranked by total cost in Luxembourg
Cheapest — long-duration promotional offers
Examples: LOL Fiber at €34.90/month × 24 months · Eltrona on promo
When available, promotional offers locked in for a full 24 months (no price hike after 6 or 12 months) are the real bargains on the Luxembourg market. Luxembourg Online has already offered its Fiber plan at €34.90/month for 24 months — a historic price floor for 1 Gbit/s fibre in Luxembourg, with installation, cabling and activation included.

Orange Livebox Fibre · Tango GO Fibre S · Luxembourg Online Fiber S
The €45–55/month range is the sweet spot on the Luxembourg market for 1 Gbit/s fibre. Orange stands out by systematically offering free installation and activation — saving €200–300 upfront. Typical 24-month total cost (modem included): €1,300–1,500. Guides: Orange internet, Tango internet.
Compare these offersBest performance/price — Tango 2 Gbit/s
Tango GO Fibre M · Wi-Fi 7 included
Tango regularly offers its GO Fibre M (2 Gbit/s, Wi-Fi 7) at the same price or very close to the 1 Gbit/s offer through promotions. For a family or intensive remote-working household, this tier often represents the best value — especially when the price difference from 1 Gbit/s is minimal.

~€30–50/month + €5/month modem + €79 installation
Eltrona’s Internet GiGA offer is the only one on the Luxembourg market with no commitment — cancel anytime, no fees. If you’re not certain of staying in Luxembourg for more than 12 months, it’s the most financially secure option. More: no-contract internet in Luxembourg.

What we notice on the Switchr internet comparison tool: The cheapest headline price is rarely the cheapest total cost. Over 24 months, the gap between the « lowest advertised price » winner and the « true total cost » winner can exceed €500 — which is why our comparison tool also displays the cost of add-ons (modem, installation fees, activation fees, etc.).

Switchr analysis based on historical observation of the Luxembourg internet market. Promotions change regularly — see our Luxembourg internet comparator for up-to-date offers.
The 2-month method: start monitoring offers two months before your commitment ends. If you find a better deal, tell your current operator — they may match the « new customer » promotional rate to keep you. Number portability is free and automatic in Luxembourg.
Negotiating with your current operator to pay less
Switching operators is not always necessary to reduce your bill. Negotiating with your current operator is sometimes more effective — no installation to manage, no waiting time, no router change. The ideal moment is 2 months before your 24-month contract ends. The approach that works:
« I’ve been a customer for [duration] and my contract ends in [X months]. I’ve found an equivalent offer at [competitor] for [€Y/month] with free installation. What can you offer to keep me as a customer? »
Depending on your profile and timing, your current operator may offer a temporary monthly discount (3–6 months), an upgrade to a higher-speed plan at the same price, or a commercial gesture on your next invoice. Nothing is guaranteed — but not asking is certain to save nothing.
After the end of your 24-month commitment, if you do nothing, your contract automatically renews — sometimes without the initial promotional conditions. In Luxembourg, the operator must inform you of your contract end and cancellation procedures one month in advance. Don’t let this window pass without comparing market offers.

Frequently asked questions — cheap internet in Luxembourg
What is the cheapest internet in Luxembourg in 2026?
The lowest currently available price depends on the promotions running at the time of your subscription. Historically, the most competitive offers have come from Luxembourg Online (as low as €34.90/month for 24 months for 1 Gbit/s fibre) and Eltrona (cable 1 Gbit/s, no commitment, with frequent promotions). Orange and Tango regularly offer fibre between €40–50/month with free installation and activation. For offers currently available at your address, check our real-time internet comparison tool.
Are cheap internet offers in Luxembourg reliable?
Yes. Low-price offers from alternative operators in Luxembourg (Luxembourg Online, Eltrona) use the same physical infrastructure as more expensive offers — the POST fibre network or Eltrona’s own coaxial network. Connection quality does not directly depend on subscription price. What varies is mainly the level of customer service, speed of fault resolution and associated options (TV, mobile). For standard residential use, a €35–40/month offer from a reputable alternative operator is as reliable as a €70/month offer from POST.
Can I get cheap internet in Luxembourg without a commitment?
Yes, with two types of solution. Eltrona Internet GiGA: cable 1 Gbit/s, no commitment, from €30–50/month (depending on promotions) + €5/month modem + €79 one-off installation. 4G/5G box (POST, Tango, Orange): fixed mobile connection without commitment, from €20–30/month. These are ideal for expats on short assignments or anyone wanting maximum flexibility. More: no-contract internet in Luxembourg.
Do cheap internet offers in Luxembourg have data caps?
No. All fixed internet offers (fibre and cable) from Luxembourg operators are unlimited in data volume — there is no monthly quota or speed reduction after a certain threshold. This is a standard feature of the Luxembourg market, regardless of whether the offer costs €35/month or €80/month.
Should I include the modem cost in my calculations?
Absolutely — it’s one of the most commonly overlooked fees. Modem rental (usually a FRITZ!Box) costs €5–7/month depending on the operator, i.e. €120–168 over 24 months. Some offers include the modem in the subscription price — always check. If you plan to stay with the same operator for more than 36 months, buying your own router (€200–269 for a top-end FRITZ!Box) may be worthwhile. More: modems and routers in Luxembourg.
