Belgian authorities are warning thousands of vehicle owners about potential fines for failing to register home electric vehicle (EV) chargers. The requirement, in place since June 2021, aims to allow grid operators to monitor and manage the increasing demand on the electricity network, but a significant number of installations remain undeclared.
In Flanders, the network operator Fluvius estimates that roughly 70,000 private EV chargers are officially registered, but believes the actual number is closer to 140,000. This means approximately 70,000 vehicle owners risk a fine exceeding 117 euros for non-compliance, according to VRT NWS reporting. The obligation to register applies even to chargers installed before June 2021.
The registration requirement isn’t unique to Flanders. It is also in effect in Wallonia and Brussels, though specific regulations vary by region, as noted by Test-Achats. The rule mirrors existing requirements for installations like solar panels and domestic batteries.
Fluvius is able to detect unregistered chargers because electric vehicles significantly increase household electricity consumption – nearly doubling it, according to energy expert Dieter Jong. This surge in demand provides a clear signal to the grid operator, prompting investigation into potentially undeclared installations.
The penalties for failing to declare a charging point differ between regions. Sudinfo reports that fines are twice as high in Wallonia compared to Flanders. Specific amounts for Brussels were not detailed in available sources.
The obligation to register is intended to help grid managers anticipate and address strain on the electricity network. Declaring installations allows them to identify areas requiring investment to support the growing number of EVs, according to Test-Achats. As of February 27, 2026, no official announcement has been made regarding an amnesty period or increased enforcement efforts.
