Where Can UK Businesses Charge their Fleet?

In the UK, there are three primary locations for EV charging: public, home, and workplace. Each location offers distinct advantages and caters to the different needs of EV users.

  • Public Charging
    Rapid Chargers: The amount of dedicated rapid charging stations, such as GRIDSERVE, is increasing rapidly in the UK. These charging stations are ideal for quick top-ups and long-distance travel.
    Overnight Charging: For slower, overnight charging, facilities are available in public car parks and on-street locations.

  • Home Charging
    Home charging provides the convenience of overnight charging, supplying all the daily driving range required by the average driver at the cheapest EV tariff rates. This is particularly beneficial for drivers who may not have regular access to workplace charging facilities.

  • Workplace Charging
    Workplace charging stands out as the most convenient and secure option for business employees. It allows the charging of electric vehicles at the workplace or vehicle depots.

Types of EV Chargers for Businesses

Businesses in the UK have several options for charging a vehicle on business premises:

AC Charging for Businesses: Slow to Fast Options

AC (Alternating Current) charging involves using the main power supply to charge EVs. The power output typically ranges from 3kW to 22kW, occasionally reaching up to 43kW. All new EVs in the UK use a Type-2 connector for AC charging, though some older models might have Type-1 connectors.

AC chargers are predominantly “not tethered”, meaning users need to provide their charging cable. This flexibility can be advantageous for businesses catering to a variety of EVs. The charging speed of AC chargers is limited by the vehicle’s maximum AC charging capacity.

DC Charging: Rapid Charging Solutions for Businesses

DC (Direct Current) charging offers much higher power, up to 350kW, facilitating rapid charging experiences. While 50kW chargers were once the norm, there’s a growing trend towards 150kW or higher chargers, reflecting advancements in technology and the need for quicker charging solutions.

Unlike AC charging, DC charging doesn’t require an onboard charger in the vehicle. The necessary powerful electronics are housed in the charging unit itself, enabling faster energy transfer.

Using a 3-pin Plug for Businesses

Granny chargers are the most basic type of EV charger, they use a standard UK 3-pin plug. While they offer the slowest charging speed, granny chargers can be a potential solution for businesses whose employees need a trickle top-up charge throughout the day. These chargers are convenient due to their compatibility with standard electrical sockets but are limited by slower charging speeds and are generally more suited to individual use rather than fleet operations.

Considerations for Businesses Switching to Electric Fleets

One of the primary challenges is finding electric vehicle charge points. Unlike petrol stations, EV chargers may not be as prominently located, often found in distant car parks or less frequented areas. For a Business to use electric vehicles in its day-to-day operations, its drivers must have access to information about all the charging stations in their vicinity, including details about connector compatibility, charging speed, and the current status of the chargers. Mobile apps have emerged as a practical solution, offering drivers a centralized platform to find this information quickly and efficiently.

Another significant consideration is the diversity of charging networks. The UK boasts over 80 different charging networks, each with its own app, card, and potentially its own subscription service. This scenario can be cumbersome for drivers, who may need to juggle multiple apps and cards and face the inconvenience of not having the right access tool for a specific charger.

Paying to charge the EVs is another aspect that businesses need to manage. While some charging points accept credit card payments, others may require a specific app or subscription-linked payment method. This variety can make the payment process complex, especially when it comes to obtaining receipts. A unified billing system, such as Paua, consolidates all charging data across the business fleet is a great idea to simplify this process.

The Cost of Charging an EV at a Business

For UK businesses transitioning to electric fleets, you need to consider the total cost of charging, not just the installation of a commercial charger. It’s not just about the electricity cost either, but also about the infrastructure, operating expenses, asset utilisation, and tax implications. By considering these factors, businesses can develop a more effective strategy for integrating EVs into their fleets and managing the associated costs.

Marginal vs. Total Cost of Commercial Charging

  • Marginal Cost
    This is essentially the cost of the electricity used for charging. Often cited when discussing home charging, this figure usually omits additional costs such as installation or maintenance of home charge points.
  • Total Cost
    In contrast, the total cost of charging includes not only the cost of electricity but also the cost of the charging infrastructure. This is more commonly referred to in the context of public charging and considers the broader expenses associated with charging.

Commercial EV Charger Installation and Operating Costs

  • Charger Types
    The choice between AC (fast) and DC (rapid/ultra-rapid) charging impacts installation costs. AC chargers are generally less expensive and easier to install, particularly in settings like car parks. In contrast, DC chargers, particularly rapid and ultra-rapid ones, are more costly due to higher installation expenses and additional civil works required.
  • Operating Expenses
    Running costs for EV chargers include software for managing tariffs, payments, and troubleshooting, along with electricity costs, maintenance, and insurance. These costs are often overlooked in home charging setups but are crucial for public chargers.

Commercial Charger Overstay Fees and Asset Utilisation

  • Overstay Fees
    Fleet managers should be aware of ‘overstay fees’ at public charging points. These fees encourage the efficient use of chargers by incentivising drivers to move on once charging is complete, especially after reaching 80% charge when the rate typically slows down.
  • Utilisation
    The frequency of charger use varies by type and location. For example, a fast charger in a car park may be used less frequently compared to an on-street charger or a rapid charger, which is expected to see multiple uses per day.

Tax Considerations for Commercial EV Charging

  • VAT
    The Value Added Tax (VAT) rates differ between home and public charging in the UK. Home charging currently benefits from a lower VAT rate of 5%, while public charging is taxed at the standard rate of 20%. This variance can significantly affect the overall cost of charging for businesses.

How to Compare Commercial EV Charger Installers

Choosing the right commercial EV charger installer is a critical decision for businesses transitioning to electric fleets. This section provides a guide on how to compare and select the best installer for your specific needs.

  1. Experience and Expertise
    Look for installers with a proven track record in commercial EV charger installations, and ideally, they have experience in dealing with similar business sizes and types.

  2. OZEV Approved Installers Only
    Ensure the installer is approved by OZEV (The Office for Zero Emission Vehicles). This is the UK requirement to install EV charging stations.

  3. Range of Services
    Look for installers who offer a range of services like site assessment, fleet management solutions, installation and after-sales support.

  4. Warranty and Maintenance
    Check the warranty offered on equipment and the availability of maintenance services.

The Steps to Installing Commercial EV Chargers

Let’s take a more in-depth look at the steps to guide you through planning and installing an EV charger at a commercial business. 

  1. Consider if the planned charger location meets the EV charger installation requirements. If you are planning to install units in a private car park you are likely to meet the requirements. The key considerations are that the parking must be off-street, you must be no closer than 2 meters away from a public road and if you are using an upstand it should be no taller than 2.3 meters high.

  2. Get a written letter of authority from the landowner. According to the Federation of Small businesses statistics, there are 5.5 million businesses in the UK and the majority of those businesses do not own their premises, they lease them from a 3rd party landlord. If you are planning to install an EV charger on a leased property you must have written permission from the property owner before doing so.

  3. Speak to a qualified EV charger installer. You can expect a site visit to discuss the installation and the type of chargers you may be interested in. The installer will need to assess the electricity supply at your premises. If you are looking to install a 22kW fast charger then you may need to upgrade your electricity supply from a single phase to a 3-phase supply.

    The installer will need to assess the consumer unit at your business, if this is dated or lacking space you can expect them to recommend upgrading this equipment. They will also likely check the route from the consumer unit to the charge station to assess if there will be any additional costs involved in working out a non-standard route.

  4. Assess if you qualify for the Workplace Charging Scheme. This government incentive provides up to 75% off the cost of a charger and installation (up to £350) in the form of a voucher. Most UK businesses can apply for this voucher provided you are only offering the charging units to staff and not members of the public. You must also declare that you are either switching to an electric fleet or that you are encouraging staff to switch. You can apply for the Workplace Charging Scheme directly from this government application form.

  5. Write an EV charging workplace policy  
    Once the EV chargers are in place and ready to use, it’s good practice to produce a workplace charging policy to guide employees and visitors around the usage of the charging points.

    The policy should cover the amount of usage permitted per employee and the etiquette around how and when they can use the charge points. Ensure the policy has been shared with the team and is visible to any visitors who may wish to use the stations.

Overall, workplace EV charging offers numerous advantages, ranging from employee satisfaction and retention to environmental benefits and cost savings.

Can I Charge Staff for Using EV Charging Points?

The decision to charge staff for using EV charging points at the workplace is ultimately up to the employer. So yes if you choose to you can charge staff to user chargers. Here are a few considerations to keep in mind:

  1. Fairness and equity
    If employers charge for EV charging, they should ensure that the system is fair and equitable. Consider implementing a transparent and consistent charging policy that applies to all employees, regardless of their vehicle type or charging needs.

  2. Employee morale
    Charging employees for using workplace EV charging points may impact employee morale, especially if it is a new cost that was previously free.

  3. Incentives and benefits
    Alternatively, employers may choose to offer EV charging as an employee benefit without charging fees. This can enhance the overall employee experience, attract talent, and demonstrate a commitment to sustainability.

Before implementing any charging fees, it is advisable to carefully consider the financial implications, employee perspectives, and the overall goals of promoting electric vehicle adoption. Openly communicate any workplace charging policies to employees and allow for feedback to ensure transparency and understanding.

Can I Reduce the Cost of Workplace Installation with a Grant?

There is an OZEV grant called the Workplace Charging Scheme that reduces the cost of workplace charger installation. The Workplace Charging Scheme provided businesses with a 75% discount on the cost of a charging unit and the installation of the unit. This is capped at £350 and cannot be used on more than 40 units per company.

Any business in the UK no matter how large or small is eligible for the grant (not only businesses, charities and public sector organisations are now able to apply too). The WCS online application form is quick and simple to use, you will need to provide business contact details, information about where the chargers are being installed and provide a declaration as to why your business qualifies.

Is Charging Your Car at Work a Benefit in Kind?

A benefit in kind is a ‘non-cash’ benefit that has a monetary value, as it has a monetary value the benefit in kind could be taxed in the same way as wages. Is workplace charging treated as a benefit in kind? No, the Benefit in Kind (BIK) rules for EVs are different to petrol vehicles and there is a tax exemption in place to ensure that workplace charging is not treated as a benefit in kind.

This exemption allows employees to benefit from workplace charging providing they are at their place of work and they are either driving or are a passenger in the vehicle being charged. The exemption will cover the electricity charge and the costs associated with the employer installing the charging station.

The Final Word on Installing an EV Charger in Your Workplace

Installing an EV charger in your workplace can bring about a huge amount of benefits. It not only provides convenience for your employees but also contributes to sustainability efforts and showcases your commitment to a greener future.

By offering workplace EV charging, you can attract and retain top talent, reduce business emissions, and lower transportation costs for both your employees and your business. Additionally, it positions your company as forward-thinking and environmentally conscious.

The workplace charging scheme and company car tax exemptions provide employers with a discounted means to install and run EV vehicles for staff. The provision of free charging units will resonate well with employees as a money-saving benefit that demonstrates the business cares about both its staff welfare and its carbon footprint.
