Installing an EV Charging Point in Brussels or Flanders: What You Need to Know (or your installer needs to know!) …<\/p>\n\n\n\n
Demand for home EV charging in Belgium keeps climbing, and on paper the job looks simple: pick a wallbox, hire an electrician, done in an afternoon. In practice, Belgium’s electricity network has a few quirks \u2014 and a company-car market unlike almost anywhere else in Europe \u2014 that can turn a straightforward installation into a more involved (and more expensive) project if nobody checks for them first. <\/p>\n\n\n\n\n\n\n\n
This guide walks through the four things worth understanding before you dive in: the type of electrical network your home is actually connected to, how much charging power your car can genuinely use, how Belgium’s capacity tariffs change the sizing question, and \u2014 because a large share of electric vehicles on Belgian roads are company cars \u2014 how ownership and reimbursement of a home charger typically work.<\/p>\n\n\n\n
Belgium’s Electrical Oddity (the uncommon electricity) : the 3x230V Network Without a Neutral<\/p>\n\n\n\n
Most of Europe’s low-voltage grid is built as a “star” network: three phases plus a neutral wire, giving 400V between phases and 230V between any single phase and neutral. That’s what ordinary single-phase sockets use, and it’s the assumption baked into most EV charger designs. Most European homes have either a full 3 phase + Neutral supply or a single phase from the 3 + Neutral.<\/p>\n\n\n\n
<\/p>\n\n\n\n The final issue is in safety equipment. Charging cars opens the household circuit to the risk of a fault in the car injecting direct current back into the home supply. The danger here is that DC over 6mA can make the standard RCD’s protecting the inhabitants from electric shock inoperable. Most, but not all, chargers have this 6mA DC protection built-in but many cheaper in cable brick chargers do not. Belgium’s uncommon electricity raises its head again as the common and cheaper devices to fit in the distribution board to protect against over 6mA DC current simply do not work with the no neutral system. Some devices are available but they are expensive. <\/p>\n\n\n\n If you already have a 3x400V + Neutral system you are in the best position. If not, you will either have a single phase 230v + Neutral (essentially one of the 3x400V phases) a 3x230v no Neutral or 2x 230V where only two of the three phases of a 3x230v no Neutral are fed to your house. In each case there will <\/strong><\/em>be a charging solution for you. <\/p>\n\n\n\n The next question is the maximum current that your installation can deliver. This is determined by the size of the circuit breaker on the input side of your meter. The maximum current, combined with the circuit type tells you the maximum power your installation can consume. <\/p>\n\n\n\n Single phase chargers are available up to 7.4kW (roughly) and 3 phase chargers to 11kW or 22kW. Before you start calculating how big a charger capacity you can have and whether you can still do the washing when you are charging your car – a word about charging capacity constraints in vehicles. <\/p>\n\n\n\n How Much Power Do You Actually Need? <\/p>\n\n\n\n The 11kW Reality Can I get more phases and\/or more power?<\/p>\n\n\n\n Maybe and usually. If your connection is an old 3x230V it might be possible to upgrade the connection to 3x400V if this is available in the street. It is also possible to ask Sibelga<\/em> or Fluvius<\/em> to come and uprate the maximum supply current to give you extra power. However, both these options come with drawbacks. <\/p>\n\n\n\n Changing the supply to 3x400V from 3x230V can be done but you will need an electrician to review the entire installation in the house and to make substantial changes to the distribution board to make this work. <\/p>\n\n\n\n Similarly, the supply companies will only upgrade the power if you have a certificate of conformity that covers the new, higher, rating. This might trigger the requirement to have the whole house re-certified and require substantial upgrade work. The upgrade itself can cost from several hundred to several thousand Euro – so not something to be done lightly.<\/p>\n\n\n\n Also, having more power available can increase you electricity bill – even if you are consuming no more energy than before. (see below on peak usage charging). <\/p>\n\n\n\n Our advice is to calculate carefully how much power you really need. There will be cases (multiple cars, the need for frequent overnight charging) where upgrades are needed but for many people their existing connection will be fine if they are prepared to charge at a lower speed and not try to run the induction hob, washing machine, dryer etc. all at the same time. <\/p>\n\n\n\n Company Cars: Who Owns the Charger, and Who Pays the Electricity?<\/p>\n\n\n\n If your electric vehicle is coming from a large company fleet or via the leasing company – you are probably not reading this article as they will be making all the decisions for you!<\/p>\n\n\n\n Here we are addressing the needs of the private owner or in this section a sole trader or small business that want to take advantage of the tax breaks for electric vehicles to have the costs of the electricity used paid for by the company or trade account. <\/p>\n\n\n\n For the tax people, you need to be able to accurately report how much electricity has been used for the car and to separate this from your general electrical use at home. This is called split billing. <\/p>\n\n\n\n The car’s electricity still flows through the homeowner’s own household meter and monthly bill, so the practical challenge is separating “car” kWh from “house” kWh and reimbursing the employee fairly for the former. The governing rule, Circular 2024\/C\/77, requires “a specific communication system that reports the electricity consumption for charging the company car to the employer” , and, for any such system bought, rented or leased from 1 January 2025, sets an accuracy bar of a maximum 2% measurement error or “class B” \u2014 in practice the standard most people mean by “MID-certified.” Usefully, though, the circular doesn’t lock the requirement to charger hardware specifically: it adds that “other forms of communication may also be accepted, provided of course that they are verifiable \u2014 an intermediate meter, for example, may also be one of the possibilities” . <\/p>\n\n\n\n In practice, most split-billing setups still put an accuracy-grade meter inside the charger itself, logging each session to a back-office platform; the employer then reimburses the employee monthly based on that consumption, capped at a maximum rate published quarterly by the regulator (CREG) per region, and staying within that ceiling is what lets the reimbursement count as tax-free cost recovery rather than taxable salary. <\/p>\n\n\n\n This opens the Belgian market for chargers to simpler designs and cheaper options. <\/p>\n\n\n\n Congratulations if you have read this far<\/strong>! Topics we still have not covered include load balancing (only charging or throttling back charging power depending on the other loads on the system), the interaction with solar, with or without battery storage systems and Car to Load or Car to House systems that allow you to use the power stored in the car.<\/p>\n\n\n\n The technical issues and the interpretation of the requirements of the tax authorities have driven the Belgian market toward high-end charging solutions that use sophisticated chargers designed for Belgian electricity, load balancing and accurate reporting. These systems tend to be expensive. <\/p>\n\n\n\n It is however possible and for many people will be the most suitable solution to have rather simpler charging set-up without all these bells and whistles but that is still safe and functional. This is especially true for hybrid vehicles with small battery capacities but will be also true for may small or one person businesses with electric vehicles. <\/strong><\/p>\n\n\n\n Uncommon Electrics can help you chose and install the system that is most suitable for you from a simple dedicated circuit with an industrial socket for an in-cable charger (especially attractive to renters who may not wish to spend a fortune on updating their landlords property!) to a full load balanced metered solution. In between there are economic options with simpler chargers that still can meet the fiscal rules. <\/p>\n\n\n\n Don’t hesitate to get in touch. <\/p>\n\n\n\n Sources & further reading<\/strong> Installing an EV Charging Point in Brussels or Flanders: What You Need to Know (or your installer needs to know!) … Demand for home EV charging in Belgium keeps climbing, and on paper the job looks simple: pick a wallbox, hire an electrician, done in an afternoon.

Belgium \u2014 and Brussels in particular \u2014 did things differently for decades. Large parts of the older network were built as a “delta” system: three live phases and no neutral conductor at all. Sibelga<\/em>, the Brussels grid operator, still puts roughly 80% of the region’s territory on this 230V network. Measured between any two phases you get about 230V (which is why ordinary single-phase appliances work perfectly well on it), but measured between a single phase and earth you only get around 130V, because there’s no neutral reference point. Pockets of older streets in Flanders carry the same legacy setup, even though Fluvius<\/em> has installed only standard 3x400V+neutral (“star”) connections for new builds for years.<\/p>\n\n\n\n
For lights, sockets and general use you would not know the difference – all is invisible. It becomes a real issue for EV charging for three distinct technical reasons:<\/p>\n\n\n\n
Safety-check failures. Many chargers and vehicles run an internal check that compares the “neutral” conductor to earth before allowing current to flow \u2014 on a proper star network that reads close to 0V. On a genuine delta network there’s no true neutral at all; each of the three live conductors sits at roughly 130V to earth. That check then reads a voltage that shouldn’t be there, and charging is refused outright or cuts out intermittently. Fluvius <\/em>specifically flags older Renault Zoe and Smart EQ models as vehicles that can struggle on this type of network but more importantly many chargers make this check themselves and will refuse to operate.<\/p>\n\n\n\n
Three-phase chargers are starved of voltage. Standard three-phase EVSE hardware is built for a 3x400V star supply. Fed from a delta network instead, it only sees about 230V phase-to-phase \u2014 too low for the equipment to deliver anything like its rated power, essentially three phase chargers for “Belgian” electricity are very rare and if the charger can be wired for three phases often it is only using one after comparing the load on each phase.<\/p>\n\n\n\n
So, before ordering any hardware, it’s worth confirming which network type serves your address. Fluvius<\/em> offers an online voltage checker for Flemish addresses, and Sibelga<\/em> can confirm the connection type for a Brussels property; alternatively, give uncommon-electrics a call and we can look together (on a video call) to see which electricity you already have. <\/p>\n\n\n\n
It’s tempting to assume that a bigger, three-phase 22kW charge point is simply “better.” In practice, the charging speed you get is capped by whichever is smaller: the charge point’s output, or your car’s onboard AC charger \u2014 the component inside the vehicle that converts incoming AC power into DC for the battery.
Most current EVs are built with an onboard charger rated at 7.4kW (single-phase) or 11kW (three-phase). Only a limited number of mostly higher-end models can actually accept the full 22kW. Paying for a 22kW-capable installation on a car that tops out at 11kW buys capacity the vehicle can never use \u2014 an 11kW three-phase connection already adds roughly 50km of range per hour, which comfortably covers an overnight top-up for almost any driving pattern.<\/p>\n\n\n\n
Another option is to install a local transformer that converts the incoming 3x230V delta supply into a genuine 3x400V+neutral star supply behind your meter, unlocking three-phase charging and universal vehicle compatibility. Costs are around \u20ac2,000 for this transformer alone, plus installation and testing. Realistically this is an unlikely option. <\/p>\n\n\n\n
Belgium’s company-car market is unusually large, and the great majority of electric vehicles ordered in the country today are fleet or lease cars rather than private purchases. That makes ownership and billing questions for the home charger just as relevant as the technical ones above.<\/p>\n\n\n\n
A newer category of “hardware-free” platforms has also started appearing on the market, estimating a company car’s home-charging cost from data the vehicle itself reports (via the manufacturer’s API) rather than from a meter in the charger. The circular’s own wording \u2014 “other verifiable forms of communication” \u2014 is technology-neutral enough that this isn’t ruled out in principle.
The key advantage of these systems is that it is not necessary to have a complicate charging device with a certified meter inside the box that usually has to be permanently connected to the internet and requires either an RFID card or vehicle recognition to attribute each charge to the car and return the data to the employer. Systems that interact with the data stored by the car can report the charging events at the users home and allow for the easy calculation of the refunds. <\/p>\n\n\n\n
