EV charger installation requirements: Everything you need to know

As the desire for electric vehicles surges, so does the need for accessible and efficient charging solutions. Installing an EV charger at home has become a pivotal step towards embracing a greener, more sustainable future. However, navigating the installation requirements can be a daunting task.

In this guide, we'll break down everything you need to know about preparing your home for an EV charger installation.

From electrical capacity to equipment specifications, we've got you covered with EV charging guides.

What are the benefits of getting an EV charger installed at home?

Installing an electric car charger at home can offer several benefits, including:

• Convenience: Charge at home overnight for a full battery in the morning, ensuring maximum range for your day.
• Cost-effectiveness: Home charging is generally more economical than public stations, with lower residential electricity rates and special off-peak tariffs for EV drivers.
• Saving time: Level 2 chargers (240 volts) charge significantly faster than standard outlets, which is especially valuable for longer commutes.
• Increased safety: Charging with a standard 3-pin plug should only be a last resort, as these sockets are not equipped to withstand the amount of power required to charge an EV battery. By installing a home EV charging port, you can reduce the risk of electrical fires.
• No waiting: Avoid potential wait times at public charging stations, ensuring prompt charging.
• Increased property value: Installing an EV charger can enhance your home's resale value, catering to the growing demand for charging capabilities.
• Additional environmental benefits: If you have a green energy tariff with a supplier that uses renewable or carbon-neutral sources, home EV chargers can help your vehicle run even more sustainably.

What type of home EV charger is right for your home?

The choice between a tethered and untethered EV charger depends on your specific needs and preferences. Here's a breakdown of both options:

Tethered chargers

A tethered charger has a fixed cable that is permanently attached to the charging unit and connects directly to your car's charging port.
The tethered charger offers a high level of convenience, as you don't need to worry about carrying a separate charging cable or storing it when not in use.

However, it's important to note that tethered chargers are designed for specific car makes and models, which means they may not be suitable for all EVs.

Untethered chargers

An untethered charger provides a charging unit with a socket but does not come with a fixed cable. Instead, you'll need to use a separate charging cable that is compatible with your specific car. 

However, it's important to consider that untethered chargers require you to store and manage the charging cable separately. This may be less convenient compared to a tethered charger, where the cable is always readily available.

EV charger installation requirements in the UK

If you're interested in installing an electric car charger, there are a few requirements you'll need to meet first.

1. Property ownership or landlord permission

To have an EV charger safely installed at your home, you typically need to be the homeowner. If you're the property owner, you have the advantage of making decisions about the installation without needing external approval, whereas if you're a tenant, it's essential to engage in a conversation with your landlord. 

This could involve explaining the benefits of EV ownership and how the installation can be a long-term asset to the property. It's important to document any agreements in writing, outlining responsibilities and potential arrangements for costs.

2. Designated parking

Ideally, to install an EV charger at your property, you should have access to off-street parking, such as a driveway or private garage. This will ensure that your charging cable reaches comfortably from your wall to your vehicle without causing obstructions.

We say “ideally” because it’s not a make-or-break requirement. That is, you could install a home EV charger on the wall outside your house and run the charging cable across the pavement to the street immediately opposite, provided you have a designated parking spot there. 

It’s just worth bearing in mind that some local councils may not take too kindly to this, as it could cause a trip hazard for people walking down your street, so it’s best to double-check local rules before assuming you can do this.

3. Wi-Fi and/or 4G connection 

An EV home charger installation will require a Wi-Fi connection (or a reliable 4G network, depending on the charger you choose). This allows the charger to connect with a central server, enabling features such as accepting instructions, adjusting the charging rate, and recording energy consumption. This is especially important for smart chargers that have advanced functionalities and can be controlled remotely via a charging app.

4. Professional installation services

Irrespective of whether you're a homeowner or a tenant, it's crucial to hire an experienced electrician to install the EV charger. This professional will possess the necessary expertise to carry out the installation safely and in compliance with all relevant electrical codes and regulations.

The electrician will conduct a thorough assessment of your home's electrical system to determine its capacity and suitability for installation. They will also ensure that the charger is connected to a dedicated circuit with the appropriate voltage and amperage ratings. This step is essential for the safe and efficient operation of the EV charger.

5. Electrical capacity & panel

One of the most crucial aspects of EV charger installation is ensuring that your home's electrical system can handle the increased load. Most Level 2 chargers, which operate at 230 volts, require a dedicated circuit with at least 40 amps.

If your current panel does not have the necessary capacity, an upgrade may be required, but this is something we’ll be able to advise on after using our Find an EV Charger tool.

What is the best location to install an EV charger?

The best location for an EV charger installation depends on various factors, including your specific circumstances and preferences. For instance, your location could be different depending on if you have a tethered or untethered EV charger.

With these two options in mind, we'll break down the best locations for both tethered and untethered chargers:

The best location for a tethered EV charger

A tethered EV charger, which comes with a fixed charging cable attached to the unit, is typically installed in a location that provides easy access and convenience for charging. Here are some considerations for installing a tethered EV charger:

• Near off-street parking: The charger should be located near your designated off-street parking area, such as a driveway or private parking space.
• Proximity to electrical panel: Consider the distance to your electrical panel. It's generally more cost-effective and efficient to install the charger closer to the electrical panel to minimise the length of wiring required.
• Weather: If possible, choose a location that offers some level of protection from harsh weather conditions.
• Accessibility: Avoid placing it in areas where it might be obscured by obstacles or be difficult to reach.

The best location for an untethered EV charger

An untethered EV charger, which does not come with a fixed charging cable, provides more flexibility in terms of location. Here are some considerations for installing an untethered EV charger:

• Access to charging port: Since the charging cable is separate, you have the flexibility to choose a location that provides easy access to your vehicle's charging port. This allows you to use different cables for different EVs, providing versatility if you have multiple electric vehicles or plan on changing your car in the future.
• Cable management: Consider where you will store and manage the charging cable when it's not in use.
• Flexibility for future vehicle changes: If you anticipate changing your EV in the future, an untethered charger provides the flexibility to adapt to different charging port configurations without the need for a charger replacement.
• Proximity to the electrical panel: As with a tethered charger, it's still important to consider the proximity to the electrical panel to minimise wiring lengths and installation costs.

Remember to consult with a qualified electrician to determine the optimal location for your specific circumstances. They will consider factors like your home's electrical capacity, parking setup, and personal preferences to help you make the best decision.

Is there anywhere a domestic EV charger can’t be installed?

Yes, there are certain places where an EV charger cannot be installed due to safety, legal, or logistical reasons. These places could include:

• Public pavements, streets, walkways or other public rights of way
• Highways or public roads
• Multi-unit residential buildings with shared parking spaces
• Rented properties without landlord's consent
• Some historic or protected buildings may have restrictions on external modifications
• Places with limited access to the electrical panel

Understanding these limitations ensures a safe and compliant installation process. Always consult with a qualified electrician and review local regulations for guidance tailored to your specific circumstances.

Other than at home, where can you charge electric vehicles?

Electric vehicles can be charged at various locations beyond the home. Here are some common places where electric car charging is available.

• Public charging stations: These are located in various places, including petrol stations, service stations and along some highways. They offer Level 2 (240V) and sometimes Level 3 (DC fast charging) options for faster charging.
• Workplace charging stations: Many employers offer EV charging station access at workplaces to facilitate employee charging during the working day. The UK government also offers the WCS (Workplace Charging Scheme), which provides financial incentives for businesses to install EV charging infrastructure on their premises.
• Hotels: Many hotels and holiday resorts offer EV charging as an amenity for guests.
• Supermarkets and shopping centres: Many large supermarkets and retail parks have EV charging points installed in their car parks to attract drivers.
• Transportation hubs: You can find an EV charge point at most UK airports, train stations, and bus terminals.

It's important to note that the availability of charging infrastructure may vary by region. EV drivers can find charging stations via mobile apps and websites to locate the nearest EV charging point and plan their journeys accordingly.
