As electric vehicles (EVs) continue to gain traction in the United Kingdom, businesses are increasingly adopting EVs for their fleets. One crucial consideration when transitioning to electric mobility is selecting the appropriate charger. In this article, we will delve into the choice between 3.6kW and 7kW chargers, highlighting the factors that UK businesses should consider to make an informed decision.

Understanding Charger Power Ratings

In the UK, the power rating of EV chargers is typically measured in kilowatts (kW). The charger’s power output directly impacts the charging speed of your EV. To determine which charger suits your business, it’s crucial to comprehend the implications of these power ratings, especially in a business context. Factors such as the size of your fleet and the daily driving patterns of your employees will heavily influence this decision.

The Advantages of a 3.6kW Charger

A 3.6kW charger is a sensible choice for businesses with smaller EV batteries and shorter daily driving ranges. This charger offers several advantages, including cost-effectiveness, reduced electricity consumption, and compatibility with standard electrical circuits. For businesses that primarily charge their EVs overnight, the 3.6kW charger is a practical and economical solution.

The Benefits of a 7kW Charger

Businesses with larger EV batteries and more extensive daily driving requirements may find the 7kW charger better suited to their needs. Its faster charging times, especially crucial for daily commuting, can significantly enhance employee productivity. Moreover, 7kW chargers are compatible with higher-capacity electrical circuits, potentially future-proofing your charging infrastructure as your fleet expands.

Considerations for Choosing Between 3.6kW and 7kW Chargers

The decision between these two charger options should be based on a thorough analysis of your business’s unique requirements. Key considerations include your fleet’s daily mileage, charging frequency, the cost difference between chargers and installation, and an assessment of your facility’s electrical capacity. Forward-thinking businesses should also factor in potential EV upgrades in the future.

Case Studies and Real-World Scenarios

To illustrate the practical implications of this decision, let’s explore a couple of real-world scenarios:

  1. The Commuter Fleet: A business with a fleet of smaller EVs primarily used for daily commuting may find the 7kW charger overkill. The 3.6kW charger would likely suffice for overnight charging, keeping operational costs in check.
  2. The Delivery Fleet: A company with larger EVs used for deliveries, covering substantial distances daily, would benefit significantly from the faster charging times offered by the 7kW charger. It ensures vehicles are ready for action during peak hours.

Installation and Compatibility

Regardless of your choice, it’s essential to consider the installation process. Ensure that your chosen charger is compatible with the make and model of your EVs. Additionally, consult with electricians who specialize in EV charger installation to assess and upgrade your facility’s electrical infrastructure if necessary.

Cost Considerations

When contemplating the cost of EV charging, it’s more than just the purchase price. Consider long-term operating costs, electricity consumption, and potential savings or benefits associated with either charger option. Businesses must factor these into their financial projections.


In the ever-evolving landscape of electric mobility, making the right choice between a 3.6kW and 7kW charger is pivotal for UK businesses. By evaluating your fleet’s unique needs, considering future growth, and factoring in installation and operating costs, you can ensure that your business’s transition to electric vehicles is not only seamless but also cost-effective. Remember, the right charger is not just about ev charging vehicles; it’s about charging your business for a sustainable and efficient future in the UK’s evolving EV landscape.
