Electrifying your fleet: the 2026 roadmap

If you are responsible for a Belgian fleet today, as a fleet manager or fleet administrator, the argument about the principle is over. The question is no longer whether you electrify, but in what order, on what budget and above all: where your vehicles will charge. That last piece comes up too late in nine cases out of ten, and it is exactly where an electrification project either stalls or runs smoothly. Below you will find the roadmap, the Belgian rules that apply in 2026, and the figures you need to estimate your cost per 100 kilometres properly.

One warning first: a lot of what you read online about this subject comes from the Netherlands and deals with bpm, MRB and zero-emission zones. None of that applies in Belgium. Everything in this article is Belgian, with the Region named wherever the rules differ.

What does electrifying a fleet actually involve?

Electrifying a fleet means gradually replacing your combustion vehicles with zero-emission cars, together with the charging infrastructure and the internal rules that make that use possible.

So it is just as much an infrastructure and HR project as a purchasing project.

Important for your scope: the 2026 tax reform covers passenger cars, dual-purpose cars and minibuses. Genuine light commercial vehicles fall outside it and remain 100% deductible, including on diesel. Your van fleet therefore follows a different tax calendar from your company cars, and that changes the sequence of your plan.

Why 2026 is the tipping point for Belgian fleets

The tax clock: only zero-emission cars stay deductible

For CO2-emitting vehicles bought, leased or rented from 1 January 2026 onwards, the deduction in corporate income tax drops to zero. Zero-emission cars remain deductible, but on a declining schedule tied to the year of acquisition: 100% up to and including 31 December 2026, 95% in 2027, 90% in 2028, 82.5% in 2029, 75% in 2030 and 67.5% from 2031.

Two things drive your planning. The percentage you secure stays locked in for the entire period of use or the entire term of the contract, so it is not a rate that slides each year. And it is the date of the purchase order or the lease contract that counts, not the delivery date. A car you order in December 2026 and receive in 2028 stays 100% deductible for its whole life.

For a fleet renewed over three years, that means something very concrete: every order you bring forward this year locks in five percentage points of deduction for the full term of that contract. The percentages and the conditions of application are set out in the circulars from FPS Finance on the greening of mobility taxation.

The charging point obligation on your car park

Quite apart from your vehicles, obligations have applied since 1 January 2025 to the car parks of non-residential buildings. They vary considerably by Region, and that is the mistake made most often in this area.

The rules for new builds and major renovations are stricter, and again they differ by Region. In Flanders, VEKA (the Flemish energy and climate agency) monitors compliance, with fines of €2,000 per missing charging point. The full overview by Region, including the thresholds for new builds, is in our guide to choosing the right charging solution for your fleet.

Two more things worth knowing. In Flanders, the obligation falls away in the case of a major renovation if the charging-related works would account for more than 7% of the total renovation cost, and Wallonia provides an exemption for buildings owned and used by SMEs. On top of that, the revised European EPBD directive is still being transposed: in July 2026 the European Commission opened infringement proceedings against every member state for incomplete transposition. So the thresholds may still change. Check the current position with your regional energy administration before you sign off on an investment case.

What your employees expect from it

The third block is not about regulation but about retention. An electric company car usually costs your employee less in benefit in kind than a comparable combustion car, because the CO2 percentage falls back to the legal minimum of 4%. For 2026, the annual minimum BIK is €1,690, roughly €141 a month.

But the same conversation also brings you your first resistance, and it is never about the car, always about charging. Anyone who can charge at home is quickly convinced. Anyone living in an apartment asks one question: what about me? You are far better off having an answer to that before the first order, not after.

And the drawbacks?

They exist, and saying nothing about them helps no one. The purchase price is higher than that of an equivalent combustion car, even though the sums flip in TCO terms. Residual value is less predictable than on a diesel, because the market is young and the technology is moving fast. Range drops in winter, typically by 15 to 25% depending on the model and the driving profile. And drivers without a private driveway need a solution that you have to organise yourself.

So why electrify anyway? Because the tax arithmetic leaves no choice for new contracts, because the cost per kilometre is lower, and because you steer the energy line yourself, which was never the case with fuel.

Six steps to an electric fleet

Step 1. Map your current fleet and driving profiles

Do not start with the cars, start with the kilometres. For each vehicle you need four pieces of data: annual mileage, average daily distance, where the vehicle is parked overnight, and the contract end date. Those four columns determine almost everything that follows, and they immediately give you the KPIs you will steer the project by later. You can build that inventory without a telematics project: lease contracts, fuel cards and the odometer readings from the last service are enough to get started.

Step 2. Decide which roles switch first

No big bang. In most fleets, a small share of the vehicles generates most of the resistance: the heavy mileage drivers and the drivers with no way of charging at home. Start with the opposite profile, the commuters with a fixed parking spot and a driveway, and use the contract end dates as your natural running order. That way you build up a series of successful switches before you tackle the difficult cases.

Step 3. Rewrite your car policy and your charging policy

This is the step that gets skipped most often. Your car policy covers the car, but without a charging policy the biggest cost line stays unregulated. Your charging policy should at least settle this: which charging costs you cover, at what rate you reimburse home charging, and who owns the home charger and what happens to it when someone leaves the company.

That last point is no detail: the law does not settle it, the charger is fixed to your employee's home, and without a contractual arrangement, preferably a right of superficies, you are inviting an argument.

Step 4. Choose your charging mix: home, office, on the road

For each driving profile, decide what share of the energy is charged at home, on site and on the road. On site, your connection capacity determines how many points you can power at once: with load balancing you distribute the available power dynamically across the connected vehicles, which is almost always cheaper than a grid connection upgrade. That is an economic decision, not a technical one. We come back to it below, because it is the line with the most margin in it. You will find an overview of the possible set-ups, and of smart charging on a company site, in our guides on the subject.

Step 5. Calculate in TCO, not in purchase price

The total cost of a company car is made up of six lines: lease or depreciation, insurance, maintenance, regional taxes, the solidarity contribution and energy. Driving electric is cheaper per kilometre, but not automatically: maintenance and, depending on the Region, the annual road tax go down, while energy becomes a variable you steer yourself.

Build in two lines explicitly that are often forgotten. The monthly CO2 solidarity contribution payable to the NSSO is €42.34 a month in 2026 for an electric car ordered from 1 July 2023 onwards, so well over €500 a year per vehicle. And since 1 January 2026, Flanders has scrapped its exemption from vehicle registration tax and annual road tax for zero-emission cars on new registrations. Cars registered up to and including 31 December 2025 remain exempt for as long as they stay registered to the same owner. Current Walloon rates are published by SPW Finances, the Flemish ones by the Vlaamse Belastingdienst (the Flemish tax administration).

Step 6. Support your drivers through the first months

The first two months set the picture your organisation keeps of the project. Three measures are usually enough: one charging card per driver, billed directly to the company, a short session on charging habits, and a single point of contact for problems. What you want to avoid is drivers paying out of pocket and filing expense claims. That costs them goodwill and costs you visibility on your energy spend.

Charging is the real bottleneck, not the car

All the model comparisons in the world weigh less on your five-year cost than the place where your vehicles charge. The table below is based on a realistic consumption of 17 kWh per 100 kilometres.

Sources: CREG for the flat rates for the third quarter of 2026, FPS Economy for the official maximum price of B7 diesel on 26 August 2026 (€2.2410 per litre), and market observation for the average public charging price.

Between the cheapest and the most expensive line there is a factor of two to three. For a fleet of twenty cars each covering 30,000 kilometres a year, that is well over €33,000 a year of difference between charging exclusively at home in Flanders and charging exclusively at public fast chargers at €0.65 per kWh, without a single kilometre changing. No choice of model delivers that. We worked out in a separate guide what charging really costs in Belgium.

So it pays to design the charging mix before you order the cars, because the mix determines which drivers can be given which vehicle. And the rate your drivers pay when they charge in public depends more on the contract behind their charging card than on the charger they happen to be standing at. A card with a negotiated B2B rate and direct billing to the company is therefore not an administrative detail but a cost line you halve with a single signature.

And your employees without a private driveway?

Not every employee has a driveway or a garage. Anyone living in an apartment, or renting without a dedicated parking space, cannot charge at home, and the honest message is that there is no trick around it. What does exist is a mix that works: charging on site during the working day, topped up with public fast charging at a fixed point on their route.

The difference between a workable situation and a painful one lies in the charging card itself. The card has to work at the stations near their home and on their route, not just on one network. Billing has to go straight to the company, so your employee never fronts the cost. And the rate has to be a contract rate, not a public charger rate. Sort that out before the order and you keep these employees on board with the project. Sort it out afterwards and you will not win them back. More on that in our overview of public charging in Belgium.

What does it cost, and what support is available in 2026?

On support, the honest answer is sobering, and you rarely see it put this plainly.

The increased thematic investment deduction (40% for small companies, 30% for large companies) does not apply to ordinary charging stations for passenger cars. The thematic list for carbon-emission-free transport limits charging infrastructure to hydrogen infrastructure for seagoing vessels and to electric charging infrastructure for zero-emission trucks, buses and coaches, and ships. Chargers for your company cars therefore fall outside it. At best they qualify for the ordinary investment deduction of 10%, which is reserved for sole traders, the liberal professions and small companies. Large companies are not entitled to it.

For investments made between 1 January 2025 and 31 December 2026 there is also a tolerance: no certification is required at the time of filing, but you do keep an evidence file.

At regional level the picture is just as thin. In Flanders there is no direct grant for ordinary charging stations for passenger cars, but there is the Ecoboostlening from PMV, a loan of €15,000 to €150,000 at 3% for SMEs and self-employed people working full time. Brussels Environment states explicitly that there is currently no grant or subsidy for installing a charging station, and the Electrify.brussels call for projects is closed. In Wallonia, the GREEN support schemes explicitly exclude charging stations.

So budget on your own funds, and spend your attention instead on the line you do control. One figure to illustrate it: according to Fluvius connection tariffs for 2026, upgrading from 17.3 to 22.2 kVA costs €401.96, while a heavier upgrade from 22.2 to 55.4 kVA comes to €1,429.70. A new medium-voltage connection (1 to 26 kV) costs €6,723.73, a connection to the high-voltage grid (26 to 36 kV) €16,388.35, each excluding VAT. On top of that comes a capacity charge of €27.59 per kVA above 17.3 kVA. Those tariffs apply in Flanders: in Brussels and Wallonia, Sibelga, ORES and RESA apply their own scales. Grid operators publish no standard lead times, and Fluvius itself notes that in saturated areas a conventional connection is not immediately possible. That is precisely why oversizing on your own site often works out more expensive than a well-designed mix.

The 5 mistakes fleet managers make most often

• Calculating in monthly rental instead of TCO. The solidarity contribution, the regional taxes and the energy do not appear in the lease quote, and together they account for a substantial share of the real cost.

• Sorting out the charging mix only after the cars. The mix determines which profile can handle which vehicle. Doing it the other way round costs you a year and part of your credibility.

• Deriving the number of charging points from the number of cars. What counts is how many vehicles stand still on your site for more than four hours at the same time, not how many are in your fleet.

• Extending a lease contract without knowing the tax consequences. An extension, or exercising a purchase option, creates a new date and can wipe out your favourable deduction percentage.

• Forgetting the employees without a private driveway. That is not an edge case but the single biggest source of resistance, and the only one you can solve with a contract.

Frequently asked questions

How do I start electrifying my fleet?

Start with an inventory of kilometres, daily distances, parking locations and contract end dates. Those four data points determine which roles switch first and what charging mix you need.

How many charging points does my company need?

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

Does my company have to install charging stations in its car park?

Since 1 January 2025, yes, above certain thresholds. Flanders and Wallonia start from more than 20 spaces for existing buildings, Brussels works with percentages. See the table above.

Are electric company cars mandatory in Belgium?

No. There is no quota. The pressure is fiscal: CO2-emitting cars ordered from 2026 onwards are no longer deductible in corporate income tax.

How much does it cost to electrify a fleet?

Mostly it depends on your charging mix. Between charging exclusively at home and charging exclusively in public without a contract there is a factor of two to three on your energy cost per 100 kilometres.

What to remember

2026 is a tipping point for two independent reasons. On tax, the window for 100% deduction closes on 31 December, and it is your purchase order that counts, not your delivery: every order you bring forward locks that percentage in for the full term. Operationally, your cost is set by the charging mix, not by your choice of model, with a factor of two to three between the cheapest and the most expensive kilowatt-hour.

For low-mileage roles there is, incidentally, an alternative to the company car: the mobility budget, in which only a BEV has qualified since 2026. The best thing to do today: pin down the current position with an inventory of driving profiles and contract end dates, add a charging policy to your car policy, and have an answer ready for employees without a private driveway. Do not count on subsidies, because for this type of investment they barely exist in Belgium any more. Do count on the line you control completely. If you are preparing ESG or CSRD reporting, you will need consumption per vehicle anyway: one more reason to have your charging data reported per driver from day one.

On the Electra network, your fleet charges at fast chargers delivering up to 400 kW, with Autocharge: the session starts automatically, with no card or app. Through a single business account you manage your drivers and their access rights, track sessions per vehicle and receive one monthly invoice, with no infrastructure of your own. For your drivers, two plans bring down the cost per kilowatt-hour, and both include the Electra charging card free of charge.

Electra+ Essential: €1.99 a month with no commitment, €0.10 off per kWh on every charge on the Electra network.

Electra+ Smart: €4.99 a month with no commitment, €0.20 off per kWh on every charge on the Electra network.

Both plans also give access to a preferential rate at Atlante, Fastned and Ionity, set out on our pricing page. Paying annually cuts the subscription by 16%.
