Subsidy Programs
Grants to ensure the success of your project
The government provides attractive subsidy programs supporting housing and sustainability, offering grants and financial incentives designed to encourage energy-efficient renovations and sustainable home construction. These subsidy programs actively promote renewable heating solutions, stimulate investments in photovoltaic systems, and incentivize both the purchase of electric vehicles and the installation of EV charging stations.
Transition Period: Old Rules and New Rules
From the 5th of January, the Klimabonus state subsidies will change with the implementation of the new legislation (subject to final adoption of the law).
This extends the current scheme by one year and introduces new subsidies for photovoltaic installations and domestic batteries, with greater consideration given to the size and power of the installations.
For offers signed between the 1st October 2024 and 4th March 2026 and for which the final invoice must be issued no later than the 31st December 2026, a transitional phase applies during which two options are available:
the former subsidy scheme, with a subsidy of 50% and a maximum of €1,250/kWc (self-consumption/energy community).
OR
the new Klimabonus subsidy scheme, the full application of which is detailed in the section below ‘From the 5th January 2026’.
This framework applies a new calculation formula based on the installed power and, where applicable, the capacity of the installed battery, and gives you the choice between:
submitting the application for assistance in the traditional way to the Environment Administration
pre-financing using the same new calculation formula, subject to compliance with the pre-financing conditions.
It should be noted that from this period onwards, installations associated with a guaranteed feed-in tariff will no longer be eligible for a subsidy.
Finally, this scheme also provides a subsidy for the installation of a battery after the installation of a photovoltaic system.

Municipal grants
Many municipalities offer additional Subsidy Programs to support your housing or sustainable mobility project. Remember to contact your local authority before starting your project! You can also simulate the municipal subsidies thanks to our aid simulator available in the Klimabonus section.
Electricity and natural gas suppliers
Since January 2015, natural gas and electricity suppliers have been obliged to achieve energy savings among consumers. Since then, energy suppliers have been offering services to assist and advise consumers on the implementation of energy efficiency measures.
So far, two subsidy programmes have been created. The enoprimes subsidies, which are paid out by Enovos and SUDenergie and the Sudstroum subsidy programme.
You can simulate the subsidy amounts proposed by the energy suppliers using our subsidy simulator on subsidies.klima-agence.lu.
You can also receive the subsidy if you are not a customer of the energy supplier. To find out how to apply for the subsidy, please visit the website of the corresponding programme:
You can find a complete list of suppliers on the website of the Institut Luxembourgeois de la Régulation:
Interest subsidy for climate loans and state guarantee
The climate loan can amount to up to €100,000 with a maximum term of 15 years and an interest subsidy of 1.5% (maximum 10% of the borrowed capital).
Also use a state guarantee for your climate loan. A state guarantee makes it easier for you to access a bank loan and reduces the costs of the collateral required by the credit institution. The amount of the state guarantee depends on the loan amount and can be a maximum of up to €50,000 for a term of 15 years.
Subsidy Programs for housing and taxation
Information on legislative and tax issues (VAT on housing, “Bëllegen Akt”) as well as on tenancy legislation (lease for residential use) is also available.
