EV Charging Station Subsidies in Luxembourg

What the public support covers

Installing a home electric vehicle charging station falls under the Klimabonus Wunnen, the national housing subsidy scheme. Support covers the charging station itself and the electrical work needed to connect it: a dedicated circuit, the required residual-current protection, and where several charging points share one connection, a load-management system.

A charging station can be combined with a solar installation or a home battery, but each piece of equipment falls under its own line of the scale. The amounts and caps applicable at the time of your application are published on guichet.lu; no figure should be assumed correct without checking the official sheet.

Single-family house versus a shared car park

The situation differs considerably depending on whether the charging point serves a single-family house or a parking space in a co-owned building. In a house, the owner decides alone, subject to the capacity of the electrical connection. In a co-owned building, installing a charger on a private space often requires a decision from the owners' association, particularly when cabling runs through common areas.

The co-ownership rules and the power available at the building's main meter shape the project as much as the budget does. Load management becomes necessary as soon as several residents install chargers on the same shared meter, to avoid exceeding the subscribed power.

The role of the authorised electrician and the grid operator

Connection work for a charging station must be carried out by a company holding a business permit for the electrician trade. It sizes the cabling, installs the required protections, and issues the compliance certificate that is essential to the subsidy file.

Depending on the charger's power and the capacity of the existing connection, a step with the grid operator may be needed to confirm or increase the available power. The electrician identifies this need during the technical visit and prepares the relevant request if applicable.

Documents and the application process

The file usually includes the company's detailed quote, the electrical compliance certificate, the paid invoice and, for co-owned flats, the owners' association decision where one is required. Check whether a prior application must be submitted before work starts: in several strands of the Klimabonus Wunnen, approval in principle precedes the order, and placing the order too early can jeopardise eligibility.

The sequence to follow mirrors other subsidy strands: free energy advice from Klima-Agence, a quote from an authorised company, prior approval where the scheme requires it, the works, the invoice, and then assembling the application file with supporting documents.

Common reasons a file is rejected

The most frequent rejections stem from work started before the required prior approval, an invoice issued by a company without the matching authorisation, or an incomplete co-ownership file lacking proof of the association's decision when needed. A missing compliance certificate, or an invoice that does not separately itemise the charger and the ancillary work, also delays processing.

Communal subsidies, separate from the national scheme, exist in some municipalities and vary from one commune to another. Check with your commune's technical department: they add to the Klimabonus Wunnen rather than replacing it.

Where to get binding figures and free advice

The applicable amounts, caps and eligibility conditions are published on guichet.lu and should be checked before any financial commitment. Klima-Agence offers free, independent energy advice that clarifies how a charging station, a possible solar installation and the available connection power fit together before you request quotes.
