Gas prices in Luxembourg: the complete guide for 2026
The price you pay for gas in Luxembourg is made up of several distinct components: the energy supply price set by your supplier, the network usage fees regulated by the ILR, mandatory taxes and 8% VAT. After a significant increase in 2025 following the end of the government’s price shield, the market is now on a downward trend in 2026. Understanding how the gas price is structured is the first step to reducing your bill and choosing the right contract.

The monthly gas bill you receive is not a single figure freely decided by your supplier. It results from the addition of four distinct components, some of which are freely set by the market and others strictly regulated by the Luxembourg energy regulator, the Institut Luxembourgeois de Régulation (ILR).
| Component | Set by whom? | Characteristic |
|---|---|---|
| Energy (supply) price | Supplier (market competition) | Varies depending on contract and chosen supplier |
| Network usage fees | ILR / Creos Luxembourg | Regulated — identical regardless of your supplier |
| Natural gas tax + CO₂ tax | Luxembourg government | Fixed by law, applies to everyone |
| VAT | Luxembourg government | 8% on natural gas in Luxembourg |
Source: ILR — Natural gas supply pricing structure, consulted June 2026.
Key point: only the energy supply price varies between suppliers. Network fees, taxes and VAT are strictly identical for all customers connected to the same network, regardless of their chosen supplier. When comparing offers, the real competition is therefore solely on the energy component.
On your bill, network usage fees appear separately from the energy price — unless your supplier offers an « integrated » contract which bundles everything into one line. In both cases, the network fee amount is the same; only the presentation differs.
2. The distribution network: Creos’s central role
Creos Luxembourg S.A. operates the natural gas transport and distribution network across the vast majority of Luxembourg’s territory. Regardless of your municipality and supplier, it is the Creos network that physically delivers gas to your meter. The city of Dudelange also manages its own local distribution network, with tariffs separately approved by the ILR.
Creos network tariffs for gas are reviewed annually by the ILR. Decision ILR/G25/37 of 3 December 2025 set the tariffs applicable for 2026. These tariffs cover network maintenance and operation, infrastructure investments and security of supply.
Default supplier: the ILR has designated Enovos Luxembourg as the default supplier for the Creos gas network. If you move into a new home without an active supply contract, you are automatically supplied at the more expensive « default » tariff. It is strongly advisable to regularise your situation quickly by contracting with the supplier of your choice.
The process of switching supplier or activating a contract after a default supply period takes between 2 and 8 working days, with absolutely no gas outage during the transition.
3. Residential gas suppliers in Luxembourg
The residential natural gas retail market in Luxembourg is concentrated around three main suppliers. According to the ILR, 7 companies hold a natural gas supply licence in Luxembourg, but only 3 are active in the household segment. This market concentration is structural and reflects the size of the Grand Duchy.
| Supplier | Residential offers | Biogas available? | Regulatory status |
|---|---|---|---|
| Enovos | Natural gas + European biomethane | ✓ (100% biomethane) | Default and last-resort supplier designated by ILR |
| SUDénergie | Classic gas + Green 50 + Green 100 | ✓ (50% or 100% local biogas) | ILR-licensed supplier, network operator in the south |
| Electris | Natural gas + green option | ◐ Depending on the offer | ILR-licensed supplier, based in Mersch |

Tariffs change several times a year at each supplier. A price observed today may be different tomorrow. To compare offers at the exact and up-to-date price, use a real-time comparator — tariff figures published in articles can quickly become outdated.
Enovos is the only supplier to hold the dual status of default supplier AND last-resort supplier, both designated by the ILR. In practice, if your current supplier ceases activity, Enovos automatically takes over without any service interruption.
4. Natural gas vs biogas: price and impact differences
The Luxembourg market stands out from its neighbours through the rise of biogas offers. Unlike fossil natural gas extracted from the ground, biogas is produced by the anaerobic digestion of organic materials (agricultural waste, biodegradable waste). It is chemically identical to natural gas and works in the same appliances (boiler, cooker), but its climate impact is radically different.
Fossil natural gas
- Fossil origin (underground, imported)
- Market price linked to international commodity prices
- Available from all suppliers
- High carbon footprint
- Dependence on foreign markets
Biogas / biomethane
- Produced from organic matter fermentation
- Partly of Luxembourg origin (e.g. Rodange)
- Available from Enovos (100%) and SUDénergie (50% or 100%)
- Carbon-neutral over its life cycle
- Slightly higher price than fossil gas
Luxembourg has around 20 biogas production units on its territory. By choosing a biogas contract, you directly support the development of this local industry and help reduce the Grand Duchy’s dependence on fossil gas imports.
SUDénergie offers a gradual approach: its Green 50 offer blends 50% local biogas with 50% conventional gas, while Green 100 represents full commitment to entirely renewable gas. Enovos, for its part, offers certified European biomethane in its dedicated green offer.
5. Gas price trends in Luxembourg: 2024–2026
The Luxembourg gas market went through a period of significant tariff turbulence between 2022 and 2025. The government had implemented a price shield to cushion the surge in energy prices. The partial removal of this mechanism in 2025 caused a substantial increase in bills: approximately +10% for gas compared to 2024.

The good news: STATEC (Luxembourg’s national statistics institute) forecasts a decline of around 7% in gas prices for 2026, driven primarily by the expected fall in natural gas prices on international markets. Enovos has already confirmed a downward trend on its energy offers from the beginning of 2026.
| Period | Market context | Residential price trend |
|---|---|---|
| 2022–2023 | Post-Ukraine energy crisis | Sharp increase, government price shield introduced |
| 2024 | Progressive stabilisation | Slight easing, shield still active |
| 2025 | Partial removal of price shield | +10% increase for gas vs 2024 |
| 2026 | Easing on international markets | Expected decrease ~7% (STATEC) |

Gas prices evolve several times a year at each supplier. Even if the general trend is downwards in 2026, some fixed-rate contracts may remain more competitive over a set period. Compare regularly — at least once a year — to make sure you benefit from the best available tariff.
6. Estimating your gas consumption and bill
Before comparing offers, you need to know your annual gas consumption. This directly determines the relative weight of each tariff component and therefore which supplier is most advantageous for your profile. A Luxembourg household’s consumption varies considerably depending on the size and insulation of the home and the appliances installed.
| Home profile | Approximate size | Estimated consumption (m³/year) | Estimated consumption (kWh/year) |
|---|---|---|---|
| Studio / well-insulated small flat | < 50 m² | 200 – 400 m³ | 2,200 – 4,400 kWh |
| Average flat or house | 70 – 120 m² | 700 – 1,400 m³ | 7,700 – 15,400 kWh |
| Large house, standard insulation | 150 – 200 m² | 1,500 – 2,700 m³ | 16,500 – 29,700 kWh |
| Old house, poor insulation | 150 m²+ | 2,500 – 4,000 m³ | 27,500 – 44,000 kWh |
These estimates are for guidance only. Your actual consumption depends on many factors (insulation, appliances, behaviour, weather).
1. Check the volume in m³ consumed over 12 consecutive months
2. Convert to kWh: 1 m³ of natural gas ≈ 11 kWh (indicative gross calorific value)
3. Enter this annual figure into a comparator to get a realistic estimate of your future bill
Tip: if you don’t have your billing history, ask your current supplier or Creos for your consumption record.
7. How to reduce your gas bill in Luxembourg
Reducing gas consumption is the most powerful lever for cutting your bill — and it doesn’t necessarily require any investment. Savings from energy efficiency are cumulative with choosing a better contract, multiplying the effect on your annual budget.
Each degree Celsius less represents around 7% savings on heating consumption. Government bodies recommend 19°C in living areas and 16°C in bedrooms at night. This is the most impactful action, at zero cost.
Price differences between suppliers can amount to several hundred euros per year for a standard household. Comparing offers once a year and switching when appropriate is a simple process — no outage, no fees. Use our gas contract comparator to identify the best deal.
Hot water is the second-largest gas consumption item after heating. Shorter showers, fewer baths and appropriate boiler temperature settings (max. 60°C) deliver significant savings without any investment.
A well-maintained boiler consumes on average 10–15% less than a poorly tuned one. Annual servicing is mandatory in Luxembourg and helps detect efficiency losses before they inflate your bill.
Insulating walls, roofs and windows is the most cost-effective long-term investment. Luxembourg offers energy renovation grants that can significantly reduce the cost of works.

8. Switching gas supplier in Luxembourg: step by step
The gas market is fully liberalised in Luxembourg. Switching supplier is a right guaranteed by European and national regulations. The process is simple, quick and results in absolutely no gas outage.
Gather your annual consumption in m³ or kWh (from your recent bills) and compare current offers on our gas comparator.
Contact your chosen new supplier (online, by phone or in branch). They handle all administrative steps, including cancellation of your old contract — you do not need to contact your old supplier separately.
The switch takes between 2 and 8 working days. You continue to be supplied normally throughout — the Creos network remains the same, only the commercial supplier changes.
At the changeover date, Creos takes a meter reading (actual or estimated). Your old supplier sends a final invoice and your new supplier begins billing from that date.
Check your current contract before switching: some fixed-rate contracts may include a commitment period or early termination fees. Variable-rate contracts are generally cancellable without charge with short notice.

Why is the gas price different from one supplier to another?
Only the energy supply component varies between suppliers. Creos network usage fees, taxes (natural gas tax, CO₂ tax) and 8% VAT are strictly identical for all customers, regardless of their supplier. Competition therefore only concerns part of the total bill — but the difference can still represent several hundred euros per year.
What is the « default supplier » tariff and is it more expensive?
The default supplier tariff applies automatically when a property has no active supply contract — typically when moving into a flat whose previous tenant cancelled their contract. The ILR has designated Enovos as the default supplier on the Creos network. This tariff is legally higher than a freely subscribed contract, as it includes a risk premium. It is therefore strongly advised to take out a contract as soon as possible after moving in.
Is there a risk of a gas outage when switching supplier?
No. Switching gas supplier in Luxembourg involves no outage whatsoever. The physical gas delivery (through the Creos network) continues uninterrupted. Only the commercial relationship changes — from your old supplier to your new one. The administrative process takes between 2 and 8 working days.
Can my supplier change the tariff during the contract?
This depends on the type of contract. A variable-rate contract allows the supplier to adjust its price at defined intervals (often quarterly or when market conditions change), with a contractual notice period. A fixed-rate contract guarantees the supply price for a set period but may include early exit conditions. Always read your general terms and conditions carefully.
Are there any government subsidies to reduce gas bills in Luxembourg?
Luxembourg offers energy renovation grants that indirectly help reduce gas consumption (insulation, boiler replacement, heat pump installation). These are managed through the myenergy programme and can cover a significant portion of investment costs. See our guide on energy grants and subsidies in Luxembourg for a full overview of available schemes in 2026.
Can I get a combined electricity and gas contract in Luxembourg?
Yes, Enovos offers combined electricity and natural gas contracts, which can simplify management (one bill, one point of contact). Some suppliers may also offer pricing benefits for customers subscribing to both energies. See our guide on dual electricity-gas contracts in Luxembourg to assess whether this option is right for you.
