EV home charging is the process of recharging an electric vehicle’s battery using a charge point installed in a residential setting, such as in a garage or on a driveway.
This is in contrast to charging an EV at a public charging station or using a rapid charging station whilst out on the road.
EV home charging typically involves plugging the vehicle into a home charging unit (also known as a wall box), which is connected directly to the premises’ electrical system.
The charging unit is then connected to the vehicle’s charging port, and the charging process begins.
In this article, we’re going to explain how EV home charging works, the process of getting an EV charger installed at home, and how to find a suitable qualified contractor.
EV home charging enables electric vehicle owners (EVO’s) to charge their cars at home using a dedicated charging unit.
The charging process typically involves plugging the EV charging cable into the car’s charging socket at one end, and the charging unit’s outlet at the other, unless the cable is tethered.
Most if not all residential charge points in the UK use a 32 amp, 3-phase electricity supply, which provides up to 7.4kWh of electricity.
A home EV charger must be installed by a fully qualified electrician.
Once installed, EV owners can use a smartphone app to remotely set up and monitor their home charging.
They can also schedule charging sessions during off-peak hours to save money (if their electricity tariff offers lower energy costs overnight), and even receive notifications when charging is complete.
Overall, EV home charging offers a lot of convenience and flexibility of charging a car at home while also providing significant cost savings compared to public charging stations, or driving a car with an internal combustion engine that requires fuel.
The process of installing an EV home charger is easy.
It typically involves the following steps:
Before the installation, a local qualified electrician or a representative from an EV chargepoint manufacturer will conduct a site survey to assess the condition of your electrical system and determine the best location for the charger.
They will then provide a quote, with possible pricing options depending on the make and model of chargepoint on offer.
For example, if you have solar panels already installed at your home, you may be able to take advantage of the energy they produce to power the EV charger, thus saving money when charging your vehicle.
Once you’ve agreed on a suitable charging unit and a price for the work, the next step is to have the charging unit installed.
The electrician will need to install a dedicated circuit and potentially upgrade the consumer unit to ensure that it can handle the additional load.
The installation typically takes a few hours, and no more than half a day’s work.
Once the installation is complete, the electrician will perform various tests to ensure the charging unit is functioning correctly and safely.
They will also provide you with a certificate of completion.
The final steps are to register the charging unit with the manufacturer to activate the warranty, as well as your electricity provider who may offer a special electricity tariff for EV owners.
It’s important to note that the installation process may vary depending on a number of factors.
These can include the type of charging unit required, the home’s electrical system, whether you want the charger integrated with an existing solar PV or any potential regulations outlined by the local authority.
It’s recommended you only work with a OZEV qualified electrician or charger manufacturer to ensure that the installation is done safely and efficiently.
The cost to install an EV home charger can vary depending on a number of factors.
This includes the make and model of charger you choose, the complexity of the installation, and where you live in the country.
Here are some rough estimates to give you an idea of how much you can expect to spend:
A 7kW chargepoint can cost anywhere from £500 to £1,000 for the unit, plus £400 to £800 for installation.
Most UK residential homes will have a 7kW unit installed, so this is most likely the type of system you will be offered.
In some rare instances, your home may have a 3-phase electricity supply, meaning you can install a rapid home EV charger offering much faster charging speeds.
A 22 kW and above charger is however much more expensive to install.
You can expect to pay around £1,000 to £2,000 for the unit, plus £800 to £1,200 for installation.
Please note that these estimates are just a rough guide, and the final cost of your EV home charger installation will depend on a variety of factors.
Additionally, there may be UK government grants or incentives available that could help offset the cost of installation.
It’s a good idea to get several quotes from local OZEV approved EV charger installers to find the best deal for your specific needs.

There are many other brands of EV home chargers available in the UK, so the best one for you may depend on your specific needs and budget.
It’s a good idea to do some research beforehand, or alternatively, speak to an expert such as an OZEV qualified EV charger installation professional before making a decision on which type is best for you.
As a general rule of thumb, most EV’s can take anywhere from 6 to 10 hours to charge from 20% to 80% using a standard 7kWh output charger.
However, the speed at which you can charge an EV at home depends on several factors.
This includes the type of charging equipment you have, the capacity of your EV’s battery, and the charging rate that your EV can accept.
It’s also worth noting that charging time can also be affected by other factors.
This includes the temperature of the battery, the current charge level of the battery, and the age and condition of the battery.
Additionally, the charging rate may be limited by the capacity of your home’s electricity supply.
So it’s important to have your electrical system inspected by an OZEV qualified electrician before installing a home charger.
The frequency at which you should charge your EV at home depends on a number of factors.
This includes your driving habits, the EV battery capacity, and the local charging infrastructure available to you.
Here are some general guidelines to follow:
Unlike conventional petrol and diesel cars, you shouldn’t wait until your EV’s battery is nearly empty before recharging.
In fact, it’s often recommended that you charge your EVas often as needed.
This is sometimes referred to as ‘top up’ charging or destination charging.
Even if it’s just a quick charge, this ensures you always have enough range for the next stage of your journey.
Many EV owners (EVO’s) find it convenient to top up their battery on a daily basis.
This ensures that the battery is always at maximum and ready to go when you need it.
This can significantly help prevent range anxiety, and means you can head off on longer journeys at a moment’s notice.
If you have a long journey planned, it’s a good idea to charge your EV to a higher level before setting off, most probably 100%.
This will give you a larger amount of range to drive with, which is particularly important if you plan to drive in cold weather or at high speeds.
It’s recommended that you avoid frequent full battery discharges, as this can reduce the battery’s overall lifespan.
Instead, try to maintain the battery at a moderate state of charge between 20% to 80%.
In summary, the frequency with which you should charge your EV at home depends on your specific needs and driving habits.
However, charging your EV frequently and avoiding full discharges can help ensure the battery lasts for many years of driving pleasure.
