How do you choose the right charging solution for your company fleet?

Most companies open this file with one question: how many charging stations do we need to install? Installers are happy to answer, and the answer is always the same, more than you thought. It is the wrong question, and it costs money. What determines your charging need is not the number of cars in your fleet, but how many of those cars sit still at the same time, long enough, in a place where you can run a cable. Below you will find the method, four fleet types with their solution, the obligations per Region and the cost items that rarely appear on a quote.

The question is not how many charging stations, but where your cars sit

As a fleet manager, do not count your vehicles but the simultaneous dwell time: how many cars are parked on your site for more than four hours at the same moment? That number is your charging need at the office. Everything else charges at home or on the road.

Two companies with forty cars can therefore land on six charging points or on twenty. An office filled with commuters who arrive at 8.30 am and leave at 5.30 pm has high simultaneity. A sales team that drops by one morning a week has almost none. Skip that count and you size on fleet headcount, paying for points that sit idle three quarters of the time.

Three charging locations, three logics

At your employees' homes, the cheapest kilowatt hour

Home charging delivers the lowest price per kilowatt hour and takes up no company land at all. For the third quarter of 2026, the flat CREG rate (the federal energy regulator) at which you reimburse home consumption is €0.3222 per kWh in Flanders, €0.3719 in Brussels and €0.3783 in Wallonia. The limit is not technical but practical: only employees with their own driveway or garage qualify.

On your site, control and visibility

Charging at the office gives you control over access and consumption, and it is visible, which helps internally. The cost rarely sits in the stations themselves but in what lies behind them: the available capacity, the cabling and, worst case, a grid connection upgrade. It is also the only charging location you have to plan ahead, because a connection is not arranged in a week.

On the road, speed and flexibility

Public fast charging costs more per kilowatt hour, but it requires no investment, no permit and no waiting list at the grid operator. It is the only solution that scales with your fleet without you building anything, and the only one that works for drivers who rarely come to the office. The rate depends more on the contract behind the charging card than on the station itself, which makes comparing charging cards more profitable than it looks.

Why almost every fleet needs a mix

No fleet consists of a single profile. As soon as yours combines commuters, field sales and pool cars, you need three charging logics. The most expensive mistake is not picking the wrong charging station, but oversizing one charging location to avoid organising the other two.

AC or DC? Let dwell time decide

When an AC charging point is enough

An 11 kW AC charging point delivers up to 88 kWh in eight hours, slightly less in practice because of charging losses and the car's onboard charger. Plenty for the daily trip of virtually every commuter. So for any car that stays half a day or a night in the same spot, AC is not just sufficient, it is also the cheapest option per point and the gentlest on your connection. Exactly how long charging takes per model and per power level, you can read in our table of charging times compared.

When a DC fast charger pays for itself

DC becomes interesting as soon as dwell time is short and rotation is high: pool cars that change driver several times a day, vans between two rounds, a depot where vehicles stay for an hour. In those cases speed is not a luxury but the condition for keeping the vehicle in use. For every other profile, a DC charger on your own site is often an expensive way to solve a problem you do not have.

The four questions that decide your choice

How many kilometres do your drivers really cover?

It is not the average that counts, but the spread. A fleet averaging 25,000 kilometres can consist of commuters doing 12,000 and sales reps doing 45,000. Those two groups do not get the same solution.

How long do the cars sit still, and when?

This is the question that sets your number of charging points. Measure simultaneous dwell time of more than four hours, per part of the day. For most offices the peak sits between 9 am and 4 pm, which means AC covers you comfortably.

What grid capacity do you have on your site?

Ten 11 kW AC points theoretically demand 110 kW of simultaneous power, which exceeds the existing connection capacity of plenty of SMEs. In practice, dynamic load balancing solves that by spreading the available power across the connected cars. That is almost always cheaper than an upgrade, and it is why smart charging on a company site is not a gadget.

Can you combine charging with solar panels?

Yes, and on a company site that is often the most profitable part of the file. An energy management system steers your charging points on the surplus from your solar panels, so you charge during the day at your own production cost instead of at the grid rate. That does require smart charging stations and control that watches your peak load: in Belgium your grid bill is partly determined by the capacity tariff, calculated on your monthly peak. Five cars starting at full power at the same time lift that peak for the entire month.

Battery storage can flatten that peak further and feed a DC charger without upgrading your connection, but the payback depends heavily on your consumption profile: have it calculated before you invest.

How many employees can charge at home?

The most underestimated question in the whole file. The answer determines how much of your energy you can charge at the lowest rate, and how many drivers depend entirely on the site and the public network. Ask it before you size, not after.

Four profiles, four charging solutions

Office with regular commuters

High simultaneous dwell time, low daily distances. AC points on site, sized on simultaneity rather than fleet headcount, with load balancing and per driver access management. Home charging for anyone with a driveway. DC is rarely needed here.

Field sales with high mileage

Little presence on site, many kilometres, unpredictable routes. Here the site is not the solution. What counts is a charging card with a negotiated rate, broad coverage on the routes your drivers cover daily, and direct billing to the company. Top it up with home charging where possible. For this profile, what matters most is knowing how to avoid queues at the charging station.

Logistics depot or pool cars

Short dwell time, high rotation, predictable cycles. This is the only profile where a genuine charging hub with a DC charger on your own land usually pays for itself, mostly in combination with a few AC points for the vehicles that stay overnight.

Employees without a driveway

Not every employee has a driveway or a garage. Anyone living in an apartment or renting without a private parking space cannot charge at home, and the cheap home rate disappears for them. The workable solution is charging on site during the working day, topped up with public fast charging at a fixed point on their route, using a card billed directly to the company. Arrange that before ordering their car. For this group, knowing where the public charging stations in Belgium are is not a detail but a daily reality.

Are you required to install charging stations?

Yes, above certain thresholds, and the rules differ sharply per Region. Do not mix them up: plenty of pages, Belgian ones included, blend the Flemish and Walloon figures.

Region	Existing building	New build or major renovation
Brussels (from 10 spaces)	Office car parks: 10% of spaces with a minimum of 2 charging points since 1 January 2025, 20% in 2030, 30% in 2035. Other publicly accessible car parks: 5% since 2025, 10% in 2030 and 20% in 2035	New car parks apply the 2035 quotas straight away
Wallonia	More than 20 spaces: at least 1 charging station and connection infrastructure for 1 in 5 spaces, since 1 January 2025	More than 10 spaces: at least 1 charging station and infrastructure for 1 in 5 spaces

In Flanders, VEKA (the Flemish energy and climate agency) checks compliance, with administrative fines of €2,000 per missing charging point and €1,000 per space without the required ducting infrastructure. Also in Flanders, the obligation lapses in the case of a major renovation if the charging related works would exceed 7% of the total renovation cost. Wallonia provides an exemption for buildings owned and used by SMEs.

One caveat: the revised European EPBD directive is still being transposed. In July 2026 the European Commission opened infringement proceedings against all member states for incomplete transposition, which means the thresholds may still shift in the coming years. Check the state of play with your regional energy administration before you lock in a project.

What does it cost, and what tax support exists?

The investment in charging infrastructure

We deliberately quote no general price range per charging point here. No official, non commercial source in Belgium publishes one, and the amounts doing the rounds come from equipment vendors. Request two or three quotes based on your own simultaneity count, and compare them per installed point, not per station. Most of the gap between two quotes sits in the cabling, the groundworks and the management platform, not in the brand of the station.

The hidden costs: grid connection upgrade, management, maintenance

What a quote rarely mentions is what happens behind the meter. According to Fluvius connection rates for 2026, upgrading from 17.3 to 22.2 kVA costs €401.96, an upgrade from 22.2 to 55.4 kVA €1,429.70, a new low voltage connection above 56 kVA €1,008.02, a new medium voltage connection (1 to 26 kV) €6,723.73 and a connection to the high voltage grid (26 to 36 kV) €16,388.35, each time excluding VAT. On top of that comes a capacity charge of €27.59 per kVA above 17.3 kVA. Those amounts apply to Flanders: Sibelga, ORES and RESA use their own rate cards.

The lead time matters just as much. Grid operators publish no standard lead time, and Fluvius itself states that in saturated areas a conventional connection is not immediately possible and that the requested capacity may only become available after grid reinforcement. That is exactly the scenario where a heavy investment on your own site costs you months while your cars have already been delivered.

Hence the core of this article: covering an occasional peak through the public fast charging network, arranged contractually, is often cheaper and faster than upgrading your connection to absorb that same peak yourself. Run the numbers on your own figures: an upgrade to 55.4 kVA costs €1,429.70 plus €27.59 per kVA above 17.3 kVA, one off but with an uncertain lead time, whereas the same peak charged on the road at a negotiated B2B rate stays a variable cost you pay per kilowatt hour and that is available immediately. This does not hold in every case: it applies above all when the peak is rare, when your site sits in a saturated area or when your drivers already charge away from home. A depot with a predictable daily peak is the exception: there, your own infrastructure does pay off.

Investment deduction and regional support

Here, honesty serves better than optimism. The increased thematic investment deduction, 40% for small companies and 30% for large ones, does not apply to ordinary charging stations for passenger cars: the relevant list limits charging infrastructure to hydrogen infrastructure for seagoing vessels and to electric charging infrastructure for zero emission heavy vehicles, buses, coaches and ships. For charging stations serving company cars, at best the ordinary 10% investment deduction remains, and that is reserved for sole traders, liberal professions and small companies.

For investments made between 1 January 2025 and 31 December 2026 there is a tolerance: no mandatory certification with your tax return, but you keep a supporting file.

At regional level the picture is just as sober. Flanders has no direct grant for ordinary charging stations for passenger cars, but it does have the Ecoboostlening from PMV, a loan of €15,000 to €150,000 at 3% for SMEs and self employed people working full time. Bruxelles Environnement (the Brussels environment agency) states explicitly that there is currently no grant or subsidy for installing a charging station. In Wallonia, the GREEN support measures explicitly exclude charging stations. So budget with your own funds.

Management and billing: the item you underestimate

One charging card or five?

No installer will tell you, but the administration around charging costs more than its maintenance. Five cards per driver means five invoices, five rates, five contact points and no usable overview whatsoever. One card with broad coverage, roaming across networks and consolidated billing to the company solves all of that in one move, and it makes the rate negotiable on top. How paying at the charging station actually works today, we set out separately.

Reimbursing home charging

If you reimburse your employees' home consumption, that is usually done at the CREG flat rate for their Region of residence, or at the lowest of the three if you want a single rate for the whole company. Four conditions apply: the charging station is made available by you, it measures consumption via a communication system that meets the accuracy requirements, the reimbursement is set out in the car policy, and only the electricity for the company car is compensated. If those are not met, the reimbursement becomes taxable pay.

Reporting per driver

Without reporting per driver and per vehicle, you do not have a charging policy but a collection of invoices. You want to see each month who charged where, at what price, and what share went to home, site and public charging. That is the only way to spot that three drivers systematically charge in public even though they have a driveway, or that a location is hitting its maximum capacity. What charging really costs only becomes clear once you can break it down per driver.

Frequently asked questions

How many charging stations does my company need?

Count how many cars sit still on your site for more than four hours at the same time, not how many vehicles you own. Two companies with forty cars may need six or twenty charging points.

What is the difference between an AC charging station and a DC fast charger?

AC charges more slowly, up to around 22 kW, and is enough whenever dwell time exceeds four hours. DC charges much faster and is meant for short dwell time and high rotation, such as pool cars or depots.

What is load balancing and do I need it?

Load balancing dynamically spreads the available power across the connected cars. As soon as you install several points, it is almost always cheaper than having your connection upgraded.

Are charging stations mandatory for companies in Belgium?

Yes, above certain thresholds and since 1 January 2025. Flanders and Wallonia start from more than 20 parking spaces for existing buildings, while Brussels works with percentages per car park type.

How do I reimburse my employees' home charging?

Usually at the CREG flat rate for their Region of residence, published quarterly, provided there is a metered charging station that you make available and an arrangement in your car policy.

Key takeaways

Start from simultaneous dwell time, not from your fleet headcount: that single number determines how many charging points you need on site, and it almost always comes out lower than what an installer proposes. Let dwell time decide between AC and DC, and keep DC for the profiles with short dwell time and high rotation. Factor in the hidden costs, because a grid connection upgrade costs not only money but also time you do not have. And know that covering a peak through the public fast charging network is often cheaper than trying to build that same peak yourself, except when the peak returns every day. Finally, do not close the file without your management model: one card, direct billing and reporting per driver, otherwise your saving dissolves into admin.
