Subsidy for the improvement of old housing
Last update
You can receive an improvement subsidy for the renovation or the enhancement of the energy efficiency of a home that is located in Luxembourg.
The law provides for 2 types of improvement subsidies:
- an improvement subsidy for renovation works in order to improve the habitability, hygiene and safety of existing housing which corresponds to a percentage of the cost incurred for the work;
- the 'Topup Klimabonus', i. e. an energy-efficiency improvement subsidy to promote sustainability, rational use of energy and renewable energy which corresponds to a percentage of the amount of the Klimabonus financial aid granted by the Ministry of the Environment, Climate and Biodiversity.
The rate of contribution of the Ministry of Housing and Spatial Planning varies depending on the composition and the income of your household.
The two types of subsidy cannot be cumulated.
Who is concerned
To benefit from these aids, you must:
- be of legal age on the date the application is submitted;
- have a right to stay in Luxembourg for more than 3 months and be listed in the National Registry of Natural Persons;
- be the owner of the home to be improved.
Prerequisites
Conditions relating to the home
The home to be improved must:
- be located in Luxembourg;
- have been occupied for the first time for more than 10 years.
Eligible works
Improvement subsidy
In order to benefit from the improvement subsidy, the works to be carried out must concern the following:
- roof covering, roof structure or zinc plating;
- drying out of damp walls;
- creation of a crawl space or equivalent mechanical insulation;
- connections to the sewer or waste-water drainage system;
- adding bathrooms and toilets, including a septic tank;
- installing water and gas pipes, and electric cabling;
- installing or renovating central heating;
- replacing windows;
- installing or replacing shutters;
- installing railings on the balcony or stairwell;
- adding or extending rooms;
- façade renovations using traditional methods;
You cannot benefit from the improvement subsidy for the following works:
- works provided for by the amended law of 23 December 2016 establishing an aid scheme to promote sustainability, rational use of energy and renewable energy in housing;
- works that only relate to ongoing maintenance or embellishments.
Topup Klimabonus
In order to benefit from the 'Topus Klimabonus', the works to be carried out must form part of the works provided for by the amended law of 23 December 2016 establishing an aid scheme to promote sustainability, rational use of energy and renewable energy in housing;
Dwelling conditions
You must use the home to be improved as your principal and permanent residence for at least 2 years after the grant of the subsidy.
If you are not yet able to live in the home at the time the subsidy is granted, you have a maximum of 3 years to move into the property. In this event, the period of 2 years begins on the date you actually occupy the dwelling. If you fail to respect this time limit, you have to reimburse the subsidy.
Absence of ownership
Neither yourself nor any other member of your household can be the owner of another home in Luxembourg or abroad.
Conditions relating to income
Your household must have received income during the year preceding:
- the date of issue of the invoices for the works carried out, in the event of the improvement subsidy;
- the date of the decision granting the financial aid in the event of the 'Topup Klimabonus'.
Your household's income must be lower than the statutory limit.
Determining the household's income
The income taken into account corresponds to the average income for the 2 calendar years preceding, as applicable, the date of issue of the invoices or the date of the decision to grant the Klimabonus financial aid.
If the household only has an income in the year in which the invoices are issued or the decision to grant the Klimabonus financial aid is made and in the year preceding that date, the income taken into account is the average of the income for these 2 calendar years.
For example:
You have undertaken works for which invoices were issued in October 2023.
Your household must have received income during the year 2022.
The average of the income for the years 2021 and 2022 is taken into account for the calculation. If the household had no income in 2021, the subsidy is calculated on the basis of the income for 2022 and 2023.
If the total income to be taken into account includes income originating from remunerated work that was only engaged in for part of the calendar year in question, such income is to be extrapolated over a whole year.
The household's monthly net income is calculated by taking into account:
- net income as stipulated in article 10 of the amended income tax law of 4 December 1967, after deduction of social security contributions and actual taxes withheld (e.g. income from paid employment or old-age pension, unemployment benefits, parental leave allowance, REVIS, RPGH, etc.);
- the maintenance payments received;
- net accident annuity amounts;
- gross earnings paid for overtime hours.
Maintenance payments made by you (for example for your children or to a divorced spouse) are deducted from the income.
Income from dependent children is not taken into account.
Social benefits are not taken into account to determine your household's net income, such as:
- family allowance;
- back-to-school allowance;
- cost-of-living allowance.
Note: the above list is indicative only. The legal and regulatory provisions prevail.
Deadlines
Applications for an improvement subsidy must be submitted within 2 years as from:
- the date of issue of the invoices for the improvement works carried out, in the event of the improvement subsidy;
- the date of the decision granting the Klimabonus financial aid in the event of the 'Topup Klimabonus'.

If a subsidy is granted to several beneficiaries, the amount of the aid is distributed equally among them.
