EV charger installation in Luxembourg: a wallbox fitted by the book, grant included

The choice depends on your supply and your driving, not on the product sheet:

• 7.4 kW single-phase: roughly 40 km of range per hour — enough for daily commutes and overnight charging.
• 11 kW three-phase: the home standard, a full battery overnight, compatible with almost every car.
• 22 kW: rarely useful at home (most cars charge at 11 kW maximum on AC); relevant for businesses and fleets.
• Dynamic load management: a module that adapts the charger to the household’s consumption, avoiding a supply upgrade.
• Tethered cable or Type 2 socket, wall or pedestal mounting, vandal protection if the charger is reachable from the street.

A well-fitted charger is mostly what sits behind the wall:

• Supply assessment: single or three-phase, available power, spare capacity in the panel.
• Dedicated circuit from the panel, conductor size matched to the run length to limit losses.
• Dedicated protection: circuit breaker and type A RCD with 6 mA DC detection, or type B depending on the charger.
• Mounting, fixing, tidy cable routing (trunking, trench or wall penetration).
• Commissioning, power setting, real charging test on your vehicle.
• Creos registration and installation report via Smarty PRO.
• Invoice and certificate for the grant application, walkthrough of the app.

Under the 2026 scheme published on guichet.lu, the State covers 50% of the cost excluding VAT of a smart private charging station, supply and installation included, capped at €1,200 — €1,400 for an ISO 15118-20 compatible charger. It is open to owners and tenants alike, with the owner’s written consent. The application is filed on MyGuichet.lu after invoicing; we provide a compliant invoice and the expected documents. For co-owned buildings, a collective smart charging management system is funded at 50% up to €40,000 per building. Current conditions and amounts: guichet.lu.

In a shared car park the issue is distribution: collective load management, individual metering, pre-wiring of spaces for future vehicles. For a business it is chargers for staff and visitors, often 22 kW, with supervision and billing. In both cases we start with an assessment of the building’s supply and a conversation with the building manager or operator — that is where the real cost of the project is decided.
