The electric vehicle revolution is underway, and businesses across the UK are recognising the importance of providing EV charging on-site. Whether you’re aiming to attract customers, support staff, or prepare your property for the future, installing EV chargers can be a smart investment. However, rushing into installation without adequate planning can result in costly mistakes and missed opportunities.
Here are ten critical factors to consider before installing EV charging stations at your business.
1. Understand your electrical capacity
First and foremost, you need to check if your current electrical infrastructure can support EV chargers. Most commercial buildings will require an electrical assessment to determine available capacity. Standard Mode 3 chargers usually need a three-phase supply and can draw 16-32 amps per unit, while rapid DC chargers demand considerably more power—often 50kW to 150kW or higher.
If your electrical supply is already at capacity, you may need costly upgrades, such as replacing the distribution board or obtaining a new supply from your Distribution Network Operator (DNO). Engage a qualified electrician or electrical engineer to carry out a load assessment early in your planning. This assessment will help you determine not only whether installation is feasible but also how many chargers you can realistically support and what upgrades might be required.
Remember that you might require DNO approval for connections exceeding 3.68kW per phase, which could extend your project timeline by several weeks.
2. Choose the right charging speed for your business model
Not all EV chargers are the same, and the best option depends entirely on how long customers or employees usually remain at your site.
- Slow chargers (3-7kW) are suitable for overnight charging and are often used in residential settings, but are generally too slow for most commercial applications unless employees are parking for over 8 hours.
- Fast chargers (7-22kW) provide about 20-40 miles of range per hour and are ideal for locations where people stay for over two hours, such as offices, hotels, shopping centres, and restaurants. They are also much more affordable to install and run, with most businesses choosing 7kW single-phase units or 22kW three-phase units.
- Rapid chargers (43-50kW AC or DC) and ultra-rapid chargers (50-350kw DC) can add over 100 miles of range in 20-30 minutes but come with significantly higher installation costs (often £30,000-£100,000+ per unit) and ongoing electricity expenses. These are suitable for motorway services, petrol station forecourts, or locations where quick turnover is necessary.
For most businesses, fast chargers (7-22kW) provide the optimal mix of cost, usefulness, and customer satisfaction.
3. Determine how many chargers you need
It’s tempting to either over-install out of enthusiasm or under-install to save money. The ideal balance depends on several factors: the number of employees or daily visitors, current EV adoption rates in your area, parking space availability, and your timeline for expansion.
A good guideline for workplace charging is to begin with one charger per 10 to 20 employees who drive EVs, with plans to increase as adoption rises. For customer-facing businesses, consider starting with 2-4 chargers and monitoring utilisation rates. Most charging management software offers analytics that can guide your expansion plans.
Remember that the UK government has set ambitious targets, including the ban on new petrol and diesel car sales from 2035. EV adoption is accelerating rapidly. Incorporating conduit and electrical capacity for future chargers during initial installation is much cheaper than retrofitting later.
4. Navigate the maze of Grants and Funding
The financial landscape for EV charger installation in the UK presents various support schemes, although they can be complex to navigate.
- The Workplace Charging Scheme (WCS) offers vouchers covering up to 75% of the purchase and installation costs (capped at £350 per socket, with a maximum of 40 sockets) for businesses, charities, and public sector organisations installing chargers for employee use.
- Local authority grants and regional funding programmes may provide extra support depending on your area. Scotland, Wales, and various English councils have their own schemes.
- Enhanced Capital Allowances enable businesses to claim 100% first-year capital allowances on EV charging equipment, offering substantial tax relief.
However, these programmes have specific eligibility criteria, application procedures, and varying levels of funding availability. The WCS, for example, requires chargers to be smart-enabled and OZEV-approved. Begin researching grants early and consider working with an experienced installer who understands the paperwork and can ensure compliance with scheme requirements.
Failing to claim available grants could result in missing out on thousands of pounds.
5. Plan your charging business model
Will you provide free charging as a perk, charge a fee to cover costs, or aim to make a profit? This choice influences your equipment selection, software requirements, and customer experience.
- Free charging is attractive and straightforward, but it means absorbing all electricity costs. It works well for employee benefits or when the goal is purely to attract customers who will spend money elsewhere in your business.
- Paid charging needs networked chargers with payment processing, which incurs initial costs but generates income. In the UK, charging can be based on time or kilowatt-hours. Think about your electricity tariff—many firms profit from time-of-use tariffs that make overnight charging cheaper.
- Membership or validation models offer charging as a benefit to loyalty programme members or validated customers, combining the appeal of “free” charging with some cost control.
Also consider whether you will charge VAT. If you are VAT-registered, you need to charge 20% VAT on commercial charging, although there are reduced rates (5%) for residential and some workplace charging situations.
6. Location, Location, Location
Where you position your chargers is extremely important. They should be easy to access and visible, but the “best” parking spots are not always the most suitable. Consider accessibility for different vehicle types, cable reach (usually 5-8 metres), protection from weather, sufficient lighting for night usage, proximity to your electrical infrastructure, and adherence to disabled parking standards.
You will also need clear signage stating that the spaces are reserved for EV charging only. Many businesses employ Parking Charge Notices (PCNs) or other enforcement measures to prevent non-EV vehicles from occupying charging bays—this issue is known as “ICE-ing” (Internal Combustion Engine vehicles occupying EV spaces).
Under the Building Regulations (Part S in England), new non-residential buildings with more than 10 parking spaces must have one charging point and cable routes for an extra one in every five spaces. Consider whether your installation helps comply with these requirements.
Don’t forget to consider future-proofing—could you add more chargers nearby if necessary?
7. Choose between networked and non-networked chargers
Non-networked (standalone) chargers cost less initially and have no monthly fees, but they lack usage tracking, remote management, or payment processing. They’re basically “plug and charge” units.
Networked (smart) chargers connect to cloud-based management platforms, enabling you to monitor usage, set pricing, control access, generate reports, receive maintenance alerts, and integrate with popular charging networks that EV drivers already use. Although they cost more initially and may include monthly subscription fees (£5-25 per charger), the data and control they offer are invaluable for most commercial applications.
Notably, to qualify for the Workplace Charging Scheme, chargers must be smart-enabled and capable of receiving and responding to signals. This increasingly includes load balancing features, which are essential if you’re installing multiple chargers and want to avoid costly electrical upgrades.
For businesses committed to managing their charging programme efficiently, networked chargers are generally a worthwhile investment.
8. Understand ongoing maintenance and support
EV chargers are generally reliable, but they’re not install-and-forget devices. You’ll need to consider warranty coverage (usually 2-3 years as standard, with options to extend), availability of local service technicians, software update procedures, wear and tear on cables and connectors (the most common maintenance issue), vandalism protection, and compliance with annual electrical safety testing requirements.
In the UK, commercial EV charging equipment must be inspected and tested regularly, usually as part of your fixed wire testing schedule. Some charging networks provide comprehensive service packages, while others leave you responsible for organising repairs.
Understand what’s included, what isn’t, and typical response times. A broken charger that remains unused for weeks causes frustration and damages your charging programme’s reputation. Seek installers who are OZEV-approved and provide ongoing support.
Allocate funds for occasional repairs and develop a plan for managing charger outages.
9. Consider the user experience
Consider the entire charging experience from your customers’ or employees’ perspective. How will they locate your chargers? Is the payment process straightforward? Can they easily check if chargers are available before arriving? What is the procedure if there is an issue?
Simple touches can make a big difference: clear instructional signage, good lighting, weather protection, nearby amenities during charging sessions, and responsive customer support contact details. Remember that the UK uses Type 2 connectors as the standard for AC charging and CCS (Combined Charging System) for rapid DC charging—make sure your equipment matches these standards.
Many businesses miss these details and end up with underused chargers even when they meet technical standards. If you join a charging network like Char.gy, Pod Point, bp pulse, or Osprey, your chargers will be listed in popular apps like Zap-Map that drivers already rely on, significantly boosting their discoverability.
Also consider accessibility—ensure your installation complies with the Equality Act 2010 and provides accessible charging options where required.
10. Plan for scalability and future growth
EV adoption in the UK is speeding up more quickly than most forecasts, driven by government policy, better vehicle options, and falling prices. What appears to be enough charging capacity now could become inadequate in just 2-3 years. Smart planning at this stage can save considerable costs in the future.
During the initial installation, consider installing extra conduit to additional parking spaces, sizing your electrical supply with future expansion in mind (discuss load balancing systems with your installer), selecting equipment and software that can scale, and thoroughly documenting your installation for future contractors.
Some businesses install “EV-ready” parking spaces where the electrical infrastructure is in place but the charger itself isn’t installed yet. This enables quick deployment when demand grows, without the initial cost of unused chargers. This method also assists in meeting Building Regulations Part S requirements for cable routes.
Consider how your charging infrastructure aligns with your broader sustainability goals and net zero commitments—many UK businesses are now required to report on their environmental impact.
