Applying for financial aid for renewable energy-based technical installations (PRIMe House 2017)
Last update
The Environment Agency (Administration de l'Environnement) grants subsidies for investments in projects aimed at rationalising the use of energy and promoting the use of renewable energy sources.
The agency grants financial aid—technical installation subsidies known as 'PRIMe House' subsidies—to subsidise the investment and installation costs of the following:
- solar thermal systems;
- solar photovoltaic systems;
- heat pumps;
- wood-fuelled boilers;
- implementation of a heat network and/or connection to a heat network.
For each type of system, potential applicants should contact the communal administration for the area where the building is located to ascertain whether a building permit is required or not.
Applications must be filed with the Single point of contact for housing assistance (Guichet unique des aides au logement) after completion of the works.
Note: PRIMe House subsidies are granted once per installation and can only be obtained for residential buildings located in Luxembourg.
Technical installations for which financial aid was granted under the 2012 financial aid scheme are not eligible.
Who is concerned
Financial aid may be applied for by any person wishing to improve the energy performance of their home (detached house or house divided into flats). Eligible candidates include:
- natural persons;
- legal persons established under private law;
- public legal persons other than the State.
Applications for financial aid may be filed by the legal representative of a group of natural or legal persons provided that the applicant is part of that group.
Applications may also be filed by the owner(s) of the residence, except when there is a change of ownership and the new owner of the residence and/or technical installation forgoes the aid in question for the benefit of the former owner who made the investments.
If a technical installation other than a solar photovoltaic system was implemented concurrently with either the construction of a new 'high energy performance' house, or with the energy efficiency renovation of an eligible existing residential house pursuant to the provisions of the amended Grand Ducal regulation of 12 April 2012, the installation in question falls under the 2012 financial aid scheme.
Prerequisites
PRIMe House aid can only be obtained for a residential building located in Luxembourg and provided that the aid is not intended for:
- a used installation; or
- the exchange, replacement or repair of a part of a system that cannot function independently of the rest of the system.
In addition, installations must satisfy certain criteria.

Solar thermal systems
- solar thermal collectors must be certified by the European Solar Keymark quality mark;
- the installation must be equipped with a calorimeter;
- the gross surface area of the collectors with complementary heating must be:
- greater than or equal to 9 m2 for flat-plane collectors;
- greater than or equal to 7 m2 for vacuum tube collectors;
- non-glass thermal collectors with polyethylene pipes and hybrid solar collectors generating hot water and electricity are not eligible for the financial aid.
Solar photovoltaic system
- the peak power capacity of the installation must be lower than or equal to 30kW;
- the installation must be mounted on the roof or the façade of the building, or incorporated in the envelope of the building, whether the building is used for residential purposes or not;
- hybrid solar collectors generating hot water and electricity are eligible as photovoltaic collectors.
Heat pumps
- the following types of heat pumps are eligible for the financial aid:
- geothermal heat pumps with vertical sensors (geothermal probes) or horizontal sensors (geothermal collecting lines and baskets) compliant with the following coefficients of performance (COP): COP greater than or equal to 4.3 in the B0/W35 regime;
- heat pumps combined with a latent heat accumulator and a solar thermal collector, compliant with the following coefficient of performance (COP): COP greater than or equal to 4.3 in the B0/W35 regime;
- direct expansion geothermal heat pumps compliant with the following coefficient of performance (COP): COP greater than or equal to 4.3 in the E4/W35 regime;
- air-water heat pumps (including vented air-water heat pumps) compliant with the following COP: COP greater than or equal to 3.1 at A2/W35 (only for near-zero energy single-family houses);
- the heating system must be able to supply the heating circuit with a maximum starting temperature of 35°C (35W). If this is not the case, the performance coefficient of the heat pump must reach at least the required threshold at W35 with the chosen starting temperature;
- the power supply of the heat pump must be equipped with an electrical meter.
Wood-fuelled boilers
- the installation must have controlled combustion (power and combustion regulation);
- wood-pellet boilers or wood-chip boilers must be equipped with an automatic feeder and ignition system;

How to proceed
Filing an application
Subsidies for renewable energy-based technical installations may be granted for both renovation projects and new constructions, and may also be applied for independently of such projects.
Applicants must send the following documents to the Single point of contact for housing assistance (preferably by registered letter), or submit them in person:
- for private individuals: the DEPA-2017 aid application form for natural persons; or
- for legal persons: the DEPA-2017 financial aid application form for legal persons.
Along with the financial aid application form, applicants must also provide:
- the detailed and receipted invoices in connection with the requested financial aid. Proof of payment of the invoices must be attached. The invoices may refer to an itemised estimate, in which case the latter must be attached to the invoice;
- one or more specific technical data sheets, depending on the type of installation:
- photovoltaic system;
- heat network or connection to a heat network;
- thermal solar installation;
- heat pump;
- wood-fuelled boiler;
- if applicable, the energy consultant's report on the technical installation(s) in question.
Given that each application may cover different domains depending on the owner's or architect's choices, the various sheets should be accompanied by any additional documents specified on the application forms.
If the application is for a co-ownership or multi-unit residence, the applicant must attach:
- appendix form COLL-2017;
- a power of attorney from each owner;
- the list of the flats, specifying the energy reference area per flat, excluding the common areas.
If the application concerns a technical installation in a new house, the applicant must also attach the hydraulic balancing protocol, if the installation concerns the following:
- a heat pump;
- a wood-fuelled boiler;
- solar thermal systems with auxiliary heating.
The Single point of contact for housing assistance may ask the applicant to provide any documents it deems necessary to process the file.
If the aid is granted, the beneficiary's file may be reviewed at any time.
The technical installations may also be eligible for financial aid for an energy performance assessment and report by an approved energy consultant. If the improvement only applies to a renewable energy-based technical installation, the subsidy will be reduced by 70 %.

Additional aid
Some communes grant supplementary aids on top of state aids for energy savings and renewable energies. The amount of aid to be received from the commune is available on the 'myrenovation' application.
The promotional bonus nova naturstroum rewards projects that promote renewable energy sources. More information can be found on www.enovos.lu.
Natural gas and electricity suppliers active in Luxembourg also offer aid programmes for the implementation of energy efficiency measures. The list of suppliers is available on the website of the Luxembourg Regulatory Institute (ILR) website:
Payment of the aid
The aid is generally transferred directly to the applicant's account.
If the application for financial aid is submitted by the legal representative of a group of natural or legal persons, the aid is transferred directly to the bank account of the legal representative, who must immediately credit the bank accounts of the natural or legal persons concerned with their respective share of the aid.
A copy of these payments must be sent to the Single point of contact for housing assistance.
Repayment of aid
If the applicant has already received the aid, they may be required to return it, if:
- the applicant is found to have made inaccurate or incomplete statements in order to obtain the aid; or
- the applicant fails to provide the Single point of contact for housing assistance with the requested declaration, information or documents.
