Car rental in Belgium follows rules that international rental companies do not always detail in their contracts. Between low emission zones, the rapid electrification of fleets, and the contractual subtleties specific to the Belgian market, we recommend mastering a few technical points before booking a vehicle.
Low Emission Zone in Brussels: What the Rental Contract Doesn’t Mention
The LEZ (Low Emission Zone) in Brussels requires mandatory registration of any vehicle before entering the area, including rental cars registered abroad. Failure to register or non-compliance with environmental standards triggers an automatic fine.
The critical point for the renter: there is no legal obligation for the rental company to inform the customer about the LEZ in the contract. In practice, the fine is first addressed to the rental company, which then passes it on to the customer with additional processing fees.
For vehicles that do not meet the allowed Euro standards, a paid daily pass costing 35 euros exists, limited to eight days per year. This pass must be purchased before entering the zone. Agencies located on the outskirts of Brussels do not always systematically inform customers about it at the counter.
Antwerp also applies a LEZ with its own eligibility criteria. We observe that the fleets of major rental companies (Europcar, Avis, Hertz) now primarily include compliant vehicles, but independent agencies or low-cost rental companies do not offer the same guarantee. Checking the Euro standard of the assigned vehicle remains a necessary precaution.
To compare rental offers suitable for the Belgian market, the LongDrivers site in Belgium allows filtering vehicles by category and duration.
Electric Fleets in Belgium: Impact on Short-Term Rentals
According to the Renta federation, nearly half of the cars for rent or lease in Belgium are now 100% electric. This proportion has rapidly increased, rising from just over a third to almost half in the span of a year.
This massive electrification changes the rental experience on several concrete levels.
- Returning the vehicle with an insufficient battery level incurs recharging fees charged by the rental company, often higher than the actual cost per kWh at a public charging station.
- The network of fast chargers in Belgium adequately covers highways (E40, E411, E19), but rural areas in Wallonia remain less well-served, which requires planning trips differently than with a combustion vehicle.
- Rental contracts for electric vehicles sometimes include a clause that restricts the daily mileage more strictly than for a combustion model, due to range limitations.
For a trip focused on Brussels, Ghent, or Antwerp, the electric vehicle poses no difficulties. For a tourist circuit covering the Ardennes, we recommend checking the actual range of the proposed model and the location of charging stations along the planned route.
Age Conditions and Young Driver Surcharge: Belgian Thresholds
The Belgian market applies stricter age thresholds than those found in other European countries. Most rental companies require a minimum age of 21 and a license held for at least one year. For certain categories of vehicles (high-end sedans, SUVs), the threshold rises to 23 or 25 years.
The young driver surcharge generally applies to those under 25 years old. Its amount varies by agency, but it is systematically added to the displayed daily rate. This additional cost does not always appear in the price during online searches, only at the time of finalizing the reservation.
A technical point often overlooked: renting a 9-seater minibus is possible with a B license in Belgium, provided that the total weight does not exceed 3,500 kg. Rental companies offering this category check the license at the counter and refuse the rental if the driver does not meet the conditions.
Fuel, Tolls, and Hidden Fees: Areas to Watch
Belgium does not impose road tolls for light vehicles. Highways are free, which is a budget advantage compared to France or Italy. However, the fuel policy upon return remains the area where rental companies recover the most margin.
The “full/full” option remains the only economically rational choice. The renter picks up the vehicle with a full tank and returns it full. The alternative offered by some agencies (prepayment for the tank) charges for fuel at a rate higher than the price at the station, without refunding unused fuel.
Cross-border fees also deserve careful reading of the contract. Belgium shares borders with France, the Netherlands, Germany, and Luxembourg. Some rental companies allow travel in these countries without extra cost, while others charge a fee per country crossed or limit insurance coverage to Belgian territory.
Picking up at an airport (Brussels-Zaventem, Charleroi) almost always incurs a surcharge related to the airport fee. Booking at an agency in the city, even a few kilometers from the airport, can significantly reduce the total price.
The Belgian short-term rental market is quickly evolving, driven by the electrification of fleets and the tightening of urban LEZs. Checking the Euro standard, fuel policy, and cross-border restrictions before signing the contract avoids most disputes observed after return.
