The #1 energy comparator in Luxembourg

The Luxembourg energy market: understand it before you compare

Luxembourg’s energy market is one of the smallest in Europe: four electricity suppliers, two natural gas suppliers and a single distribution network across the whole Grand Duchy. That concentration has a very tangible consequence: for the same level of consumption, the difference between two bills amounts to a fraction of the total sum. Knowing what that fraction is means knowing exactly where you can take action — and where there is nothing to be gained.

Who does what: Creos, the suppliers and the ILR

Three players, three distinct roles, which consumers often confuse.

• Creos Luxembourg is the sole operator of the electricity and gas networks. It owns and maintains the power lines, gas pipes, substations, meters and connections. It is a regulated monopoly: you don’t choose it, you can’t switch away from it, and its network charges are exactly the same, regardless of which supplier you use.
• The suppliers — Enovos, SUDénergie, Sudstroum and Energy Revolt — buy energy on the markets and resell it to you. They do not own any distribution infrastructure. This is the only part of your bill that is open to competition, and therefore the only option you have.
• The ILR (Luxembourg Regulatory Institute) oversees the entire system: it approves network tariffs, guarantees every supplier non-discriminatory access to the Creos infrastructure, publishes reference benchmark prices and ensures that no switch is ever obstructed.

In practice, your bill is broken down as follows:

This is also why an offer labelled «cheaper» is not cheaper in absolute terms: it is cheaper on the comparable share. Our comparison tools nevertheless show the monthly all-inclusive price, including network charges and taxes, so the amount shown is exactly what you will actually pay.

What liberalisation allows you to do

Since the market liberalisation brought about by European directives, every household in Luxembourg has rights that are not dependent on its supplier, its local authority, or whether it owns or rents its home:

• Choose freely your electricity supplier and, where the network reaches your property, your gas supplier — these may be two different companies.
• Switch free of charge: No supplier may charge administrative, cancellation or activation fees for a straightforward switch.
• Switch without interruption: the supply is uninterrupted, with no technical work, no engineer visits and no meter replacements.
• Reject all forms of discrimination: Creos must supply energy from every supplier under strictly identical conditions.

One point worth noting: most residential contracts have no minimum term and can be cancelled at any time, but a fixed-price offer is valid for a set period (often two to three years). Check this in the terms and conditions before signing up, and then again when the offer expires — as this is often when an expired contract automatically switches to a less favourable standard rate.

Electricity, gas or both? A three-question guide

1. Do I need an electricity contract? Always. No home in Luxembourg can function without one, and the need becomes even greater if you have a heat pump, electric heating or electric underfloor heating, or if you charge a vehicle at home.

2. Do I need a gas contract? Only if your home is connected to the natural gas network and fitted with a gas boiler, a gas water heater or a gas hob. The gas network does not cover the whole area: some streets, some villages and many new-build properties simply have no access to it. If in doubt, the presence of a gas meter is the first indication; the connection can then be checked with Creos.

3. Do I need both? This is the case for most households in Luxembourg: a gas boiler for heating and hot water, and electricity for everything else. Conversely, a home with a heat pump requires only an electricity contract — but with significantly higher consumption, which makes it all the more worthwhile to compare prices.

The dual pack: the one truly cross-energy choice

Only two suppliers sell both electricity and gas in Luxembourg. Bundling both energy sources with one of them — the «dual pack» — is the one decision that cannot be made using either the electricity comparison tool or the gas comparison tool.

• What you get: one monthly bill, one customer service point of contact, one record to update when you move house, and sometimes a welcome discount.
• What you lose: the ability to choose the best deal for each energy type. Two of the four electricity suppliers do not sell gas — if they offer the best deal on electricity, a dual-energy package automatically rules them out.
• The blind spot: Gas and electricity tariffs do not change at the same rate or in the same direction. A package that was the best option when you signed up may no longer be so twelve months later, with no warning.

Our method: compare electricity and gas First, work out the two best offers separately, then compare that total with the dual pack. If the difference is small, the convenience of having a single contract often justifies taking the bundle. If it exceeds a few dozen euros a year, two separate contracts remain the rational choice.

Switching suppliers: the process, step by step

The change is purely administrative. Nothing actually happens at your home.

• 1. Gather three pieces of information — your metering point number (or Creos meter number, as shown on your current bill), a recent meter reading, and your IBAN for the direct debit.
• 2. Sign up with the new supplier — usually online, stating your preferred switch date.
• 3. Do not cancel anything yourself — the new supplier deals with the cancellation with the previous supplier. A cancellation sent by you at the same time is the single most common cause of a file being blocked.
• 4. Wait for the switch — typically two to four weeks. Your former supplier then issues a final bill based on the meter reading on the switch date. You will never be billed twice.

The 2026 state subsidy: what has changed on your bill

The tariff shield introduced during the energy crisis expired at the end of 2025. On 1 January 2026 It was replaced by a mechanism of a different nature: rather than capping the price of energy, the State now directly covers A large proportion of the Creos network’s electricity charges — around 8 cents per kWh, amounting to approximately €150 million over the year.

There are four features worth retaining:

• It is automatic — no application, no form, no means testing. The reduction is shown directly on the bill.
• It covers households and businesses equally, without distinction as to status.
• It is guaranteed for at least three years, providing an unusual insight into this cost item.
• It applies to electricity, via the network charges. Gas is not covered by this mechanism.

At the same time, funding for the development of renewable energy — which was previously included in every bill — has been transferred to the State budget. Combined with a fall in wholesale prices, these changes have stabilised, and in some cases reduced, electricity bills in 2026. They change nothing about the gap between suppliers, however: the subsidy applies equally to all of them, and the competitive element remains unchanged. Network charges are set out in our Creos network tariff guide.

The four suppliers in the residential market

Enovos is the country’s longest-established and largest supplier, with over 250,000 customers. It is the only provider to cover a household’s full range of needs — electricity, natural gas, a dedicated electric vehicle tariff and a dual-pack on a single bill — and it offers both fixed-rate and index-linked tariffs.

SUDénergie, formerly SUDGaz, is the the only alternative supplier on the Luxembourg gas market, which makes it structurally important: without it, the residential gas market would be a de facto monopoly. It also sells electricity and specialises in biogas produced locally in Luxembourg.

Sudstroum, an electricity distributor based in the south of the country, specialises in 100% renewable electricity and fully digital management: online subscription, billing and consumption tracking, which keeps its overheads low.

Energy Revolt is a citizens’ cooperative: subscribers can become shareholder-members and take part in decision-making. The electricity supplied is green and locally produced, and bills are based on actual consumption rather than a monthly average.

Taking it a step further

• Energy prices — the Luxembourg tariff structure, the price of electricity per kWh and the price of gas per m³ are set out in our kWh price and petrol price guides.
• Green energy — Renewable electricity certified by guarantees of origin and biogas from anaerobic digestion are two distinct products, covered by two different contracts. Our green electricity in Luxembourg The guide explains what each label actually covers.
• Heating — gas boiler, heat pump or pellets: your choice will affect your bills for fifteen years and determine the type of contract you’ll need. See the gas boiler vs heat pump analysis and how to cut your heating bill.
• Electric vehicle — Charging at home alters the consumption pattern enough to justify a specific, often dual-rate contract. See EV electricity plans and how off-peak hours work.
• Self-consumption — Solar panels do not eliminate the need for an electricity contract: they reduce the amount of electricity drawn from the grid. See our solar panels and electricity supplier guide.
