Belgium is in the midst of one of the most significant mobility transitions in its history. By 2026, virtually all newly registered company cars will be electric — driven by tax reforms, climate targets, and the shift towards sustainable mobility.
Yet behind this progress lies a surprising paradox. Home charging — the most cost-effective, sustainable, and comfortable way to charge an electric company car — is being massively underused. And it's not due to technical limitations. It’s a financial and fiscal issue.
MobilityPlus currently manages nearly 20,000 charging points in Belgium, half of which are located at employees’ homes. Our analysis reveals:
These numbers are alarming — and were recently reported in De Tijd, based on our internal data.
We identified three key reasons:
Since January 1, 2023, part of the electricity bill in Flanders is calculated based on the highest 15-minute peak consumption within a month. A home charging session that overlaps with cooking, laundry, or heat pump use can dramatically increase this "capacity tariff." To avoid that risk, employees avoid charging at home altogether.
A fiscal circular in effect since early 2025 allows home charging to be reimbursed at the actual cost until January 1, 2026. Pending tech solutions to automate this, the government also permits temporary flat-rate reimbursements, capped at the so-called “specific CREG tariff.”
Under this scheme, reimbursements remain part of the company car’s benefit in kind (BIK) and are not subject to additional taxation. As a result, many companies default to the CREG tariff — a uniform kWh rate — rather than reimbursing based on actual energy costs. But every employee has a different energy contract, charging time, and usage pattern.
These flat rates:
The result? Employees with cheaper contracts are overcompensated; others are underpaid — leading to frustration, mistrust, and perceived unfairness.
MobilityPlus compared the flat-rate CREG tariff to actual home charging costs under our management and observed significant deviations. That gap is expected to widen in Q2, as the CREG rate increasingly diverges from real electricity prices.
In short: the current system is neither fair nor future-proof.

Five years ago, load balancing was the go-to solution for home charging installations. Today, it no longer suffices. The introduction of the capacity tariff in 2023 changed the rules entirely.
Whereas load balancing aims to prevent technical overload, the capacity tariff is purely about one thing:
Your highest 15-minute peak of the month determines your grid cost.
That’s the crux of the problem:
Load balancing solves technical issues — but does not reduce your capacity tariff.
Load balancing is technically smart — but financially blind.
Let’s say an employee has a single-phase 40A connection:
Now imagine a three-phase 3x400V 40A connection charging at 22 kW:
Some chargers allow you to set a cap — a max charging speed (e.g., 4 kW). You can also limit the grid connection in software. But:
Result: unnecessarily high peaks and hundreds of euros lost each year.
At MobilityPlus, we’ve not only analyzed the problem — we’ve tackled it head-on. And today, we’re proud to offer a solution that works.
A smart charging strategy and car policy — combined with real-time insights and automatic reimbursement — doesn’t just keep employees happy.
It saves employers up to €1,500 net per EV driver per year.
