# Chargers for your business: where to start > Installing charge points as an employer? Work out how much power you need, how load balancing helps and when a charger on your site adds little. Published: 2026-08-04 · Language: en · Source: https://laadpaalvinden.be/en/blog/install-chargers-for-your-business/ A charge point at your business can help employees and attract visitors. What you need to install depends on who will charge and how long the car stays parked. Work that out first and you won't pay for power nobody uses. ## Start with who will charge Employees with a company car, employees with a private car, visitors, customers: each group has different needs. Parking time matters most. An example. An employee drives 40 km each way every day, in a car that uses 18 kWh per 100 km. That is 80 km × 0.18 kWh = 14.4 kWh per day. At 7.4 kW, that takes just under two hours. At 3.7 kW it takes almost four. If the car sits in your car park for eight hours, even a slow charge point is enough. A customer who stays for half an hour is a different case. At 11 kW they add at most 5.5 kWh in that time, around 30 km of range. You won't fill a battery that way. How fast a car really charges also depends on the car itself.

If they all charge flat out at once, that is 88 kW on top of what your building already uses. Many connections cannot handle that. With dynamic load balancing, the available power is shared between the cars plugged in. Cap the total at 44 kW and each car gets 5.5 kW in the worst case. Over eight hours that is 44 kWh, more than three times the 14.4 kWh from the example above. You can install more points without upgrading your connection. A qualified installer will check your connection, your total consumption and the cabling. Upgrading a connection goes through your grid operator. Costs and lead times vary, so ask early. ## Payment and billing You can offer charging for free, or via a card, an app or a bank card. With free charging you pay for every kWh yourself: multiply the expected consumption by your own tariff and you will see quickly what it costs per month. The page on [free charging](/en/free-charging/) explains why free public charging has all but disappeared. If employees with a private car charge at your expense, choose a point that measures the kWh delivered per session. Talk to your accountant about how to reimburse or invoice that. A management platform can take over metering, invoicing and access. Compare several providers and look at the monthly cost per point. ## Public or private? A charger that is open to the public can be shown on the [map](/en/map/). That brings visitors, but also strangers' cars that stay for hours if you don't set rules. A private charger stays for your own people. Choose deliberately and make it clear on the car park itself. ## Grants and tax Grants or tax advantages for charging infrastructure sometimes exist. Amounts and conditions change regularly and depend on your situation. Look up the current rules and have your accountant or installer check them before you sign a quote. ## Maintenance and faults A charger needs software updates, the occasional repair and someone who follows up on fault reports. Agree beforehand who does that and how fast. Without an agreement, a broken charge point often stays out of use for a long time. Put a contact number on the charger. ## When it adds little - Your employees live nearby or charge at home, and cars only stay briefly. - You rent the building. You then need the landlord's permission for work on the electrical installation. - You only have a few parking spaces and they are already taken. In those cases a single point for visitors may be enough, or a charging card or allowance for public charging may be cheaper. ## A practical plan 1. Count how many cars will charge and how long they stay. 2. Work out the daily kWh per car, as above. 3. Have an installer check your connection and ask for load balancing in the quote. 4. At the first installation, lay conduit for extra points so expanding later is cheaper. 5. Decide how you will bill and who follows up faults.
