Eligible renovation works 

You can contact our advisers via the contact form or by telephone on 40 65 64 63. 

Premiums are not granted for new constructions. However, you may submit a premium application if you improve energy efficiency after your home has been completed and after you have moved in.

For all works, the respective artisan-partners submit a premium application. Therefore, you will receive a premium offer for each measure and you will be able to evaluate all the works separately. The different premiums will be paid to you upon completion of the works and once the artisans have finalised the applications.

If you have a tradition, gas or oil boiler, it may be one of the following types: “constant temperature boiler”, “low-temperature boiler”, or “condensation boiler”. If you are unsure of the type of boiler you have, please contact your heating engineer. Wood/pellet-burning boilers and heat pumps are different types of boilers. This information can be found on the boiler’s data sheet.

The thermal conductivity of a window is the window’s behaviour at the time of heat transfer by conduction. It represents the energy transferred through the window. Thermal conductivity is expressed in W/m2K. This information can be found on the window’s data sheet.

The thermal conductivity of an insulator is the material’s behaviour at the time of heat transfer by conduction. It represents the energy transferred through the insulator. Thermal conductivity is expressed in W/m2K. This information can be found on the insulator’s material data sheet.

Energy savings are expressed in kWh or MWh but do not necessarily correspond to the energy savings shown on the annual energy invoice thanks to the works carried out.

Yes, you can obtain enoprimes premiums for works carried out in your secondary residence provided that it is located in the Grand Duchy of Luxembourg.

The amount of the invoice does not have a direct impact on the amount of the premium. However, the premium may not exceed the total amount of the investment.

No, the premiums are not capped. The energy saving achieved determines the amount of the premium. The higher the energy savings, the higher the premium.

Please read the “Eligible works” page of this website. It contains information on the different types of eligible works.

No, if you obtain an enoprimes premium, you cannot submit another premium application to another energy provider under the mechanism of obligations relating to energy efficiency. The energy saving achieved with the completion of a project can only be subsidised by a single provider.

Yes, you can also apply for State or municipal assistance, even if you have already obtained an enoprimes premium. The various types of assistance can be combined.  

A single project in a given housing may only receive one enoprimes premium. If, however, you improve the energy efficiency of the same project, you can once again submit an enoprimes application, given that energy savings will likely be achieved as a result of the improvement.

The enoprimes programmes provides support to private individuals and professionals, industries and non-State institutions.

enoprimes is the subsidy programme set up by Enovos to meet the obligations contained in the European Energy Efficiency Directive. With enoprimes, renovation and energy efficiency improvement works are subsidised.
