Purchasing an electric vehicle brings many benefits, including the convenience of charging at home. However, before installing a charging station, it is crucial to check if your consumer unit is suitable. Upgrading a consumer unit is often necessary to ensure safe and efficient charging.
- Check the current capacity of your consumer unit.
- An upgraded consumer unit offers higher charging speeds and increased safety.
- Always have the upgrade work carried out by a certified installer.
- The costs of an upgrade vary, but it is an investment in the future.
Why upgrade your consumer unit?
Most households in the Netherlands have a 1-phase connection with limited power capacity (e.g., 1x25A or 1x35A). However, a modern electric vehicle charging station requires significant power. To charge your car quickly and safely, a 3-phase connection with a higher capacity (e.g., 3x25A) is often required. Without this upgrade, charging may be slow, or issues such as tripped fuses may occur.
The process of upgrading a consumer unit
Upgrading a consumer unit is a specialist job that must always be performed by a certified installer. The process typically includes the following steps:
- Assessment: The installer assesses your current consumer unit and the necessary modifications.
- Application to the grid operator: The installer assists you with the application for a capacity increase with your grid operator.
- Installation: The consumer unit is modified with new components, such as a 3-phase main switch and additional circuits.
- Charging station connection: After the upgrade, the charging station is safely connected to the new installation.

Costs and considerations
The costs for upgrading a consumer unit can vary depending on your current situation and the required modifications. As an indication, you should consider an investment that may vary. These costs consist of the application to the grid operator, material costs, and the installer's labour costs. Although this is an investment, upgrading your consumer unit offers benefits not only for your charging station but also for the overall electrical safety and future-proofing of your home, for example, when purchasing other energy-efficient appliances such as a heat pump.

Frequently asked questions
Is a consumer unit upgrade always necessary for a charging station?
Not always, but often. For faster and more efficient charging, it is almost always recommended. A 1-phase charging station may suffice in some cases, but the charging speed will be significantly lower.
How long does it take to upgrade a consumer unit?
The actual installation by the electrician usually takes half a day. However, the total lead time, including the application to the grid operator, can take several weeks.
Can I upgrade my consumer unit myself?
No, this is strongly discouraged. Working on a consumer unit is complex and involves risks. Always leave this to a certified and qualified installer such as Energie Install.
