Charging Your Electric Car at Home: Everything You Need to Know

Summary

This guide covers everything you need to know about EV charging at home, from installation costs to optimising efficiency and choosing the best charger for your needs.

With nearly 1.3 million fully electric vehicles now on UK roads as of 2024 —a remarkable 500% increase since 2020, according to Zapmap—it’s clear the EV market is booming. Whether you’re thinking of joining this growing trend or you’re already driving electric, understanding how to charge an EV at home is key to making ownership as convenient as possible.

Why Charging Your EV at Home is a Smart Choice

Charging your EV at home offers unmatched convenience and several other benefits that can make your electric driving experience smoother, more cost-effective, and environmentally friendly.

Key Benefits of Home EV Charging

Home EV charging is as simple and intuitive as charging your phone. Just plug your car in when you get home, and by the time you’re ready to head out the next day, it’s fully charged and good to go. This effortless routine fits seamlessly into your lifestyle, eliminating the need for time-consuming trips to public charging points. With the convenience of overnight charging, your car is always ready when you are, making electric driving not only eco-friendly but also incredibly practical.

Average Costs

According to Checkatrade, the average cost of installing an EV charger is around £1,000, including the charger itself. Landlords and renters may be eligible for a government grant of £350, reducing the cost to around £650.

Factors Influencing Installation Costs

Costs can vary depending on your property. For example, if cabling needs to be run underground, additional work such as trenching and backfilling may increase the price. Always compare quotes from trusted suppliers to find the best deal.

The Cost of Charging an Electric Car at Home

Wondering how much it will cost to charge your electric car at home? Our easy-to-use calculator tool gives you a clear estimate based on your vehicle’s battery size, electricity tariff, and charging habits. Whether you’re new to EV ownership or simply looking to optimise your costs, this tool will help you plan your charging routine with confidence and convenience.

The cost of charging your electric car, much like the charging speed, depends on several factors. These include the type of charging point you choose to install, your vehicle's specifications, and the EV charging tariff provided by your energy supplier.

To get a personalised estimate, use the calculator below. Simply enter a few details about your EV and home setup, and discover how much it could cost to charge your car at home.

Optimising EV Charging at Home

Maximising efficiency and minimising costs is all about choosing the right energy tariffs and understanding your options.

EV Tariffs

EV-specific energy tariffs offer reduced rates during off-peak hours, typically overnight. Providers like British Gas, EDF, Octopus Energy, and OVO Energy offer EV-friendly tariffs. It’s worth noting that the majority of suppliers will require you to have a smart meter installed. This will allow your supplier to track your electricity usage at different times of the day, and make sure the reduced nighttime rate is applied properly. 

Grid vs Green Energy

Grid Energy

“Grid energy” refers to the energy supplied through the UK national grid infrastructure. While an increasing proportion of this energy comes from renewable sources such as wind and hydroelectric power, some will still be rooted in non-renewable fossil fuels.

  • Pros: Quick and easy setup, reliable energy supply, and lower upfront costs.
  • Cons: Variable pricing and partial reliance on fossil fuels.

Green Energy

“Green energy” refers to electricity from sustainable energy systems set up on your property, such as wind turbines or solar panels, which can supply your vehicle with charge without you having to rely on the electrical grid.

  • Pros: Reduced environmental impact and long-term cost savings.
  • Cons: High upfront installation costs for solar panels or wind turbines, and potential supply limitations without battery storage.

How Fast Can You Charge an Electric Car at Home?

Home Charging

The speed of charging depends on two factors: the power output of your EV charger, and your EV’s battery size.

While an average electric car takes roughly 8 hours to charge an empty battery to full on a 7 kW charging point, this time may be higher or lower depending on the infrastructure you have for EV charging at home and the specific car you’re driving.

EV chargers come with a range of power outputs, but they can generally be grouped into three categories to help you understand their charging efficiency.

Charging Speeds for a Typical EV

Understanding charging speeds is key to managing your EV’s battery effectively. Let’s use a typical electric vehicle with a 40 kWh battery as an example:

  • Slow Chargers (2.3–3.7 kW): These chargers are less common for home use and are typically found with standard 3-pin sockets. Charging a 40 kWh battery can take between 11–17 hours for a full charge. While these chargers are an option in a pinch, they may not be ideal for regular use.
  • Fast Chargers (7–22 kW): A 7 kW charger, now the most commonly installed unit at home, can charge the same battery in 4–8 hours. With its overnight charging capability, it’s a convenient and efficient choice for home use. Faster 22 kW units, often found at public charging points, can significantly reduce charging times.

Slow Chargers

Slow chargers typically offer a power output of 2.3 kW to 3.7 kW, with an empty-to-full charging time of around 8 to 12+ hours. These are sometimes used for at-home charging, either with a dedicated slow charger or a standard 3-pin plug. When EV vehicles were first launched, 3.7 kW home chargers were commonly installed, but in recent years these have been superseded by 7 kW home chargers as the most common home charging installation. 

Fast Chargers

Fast chargers offer a power output of around 7 kW to 22 kW, which is the typical range used for private at-home charging points. The empty-to-full charging time for this category can be as little as 4 hours or as long as 8. These chargers are typically more expensive to install at home than Slow Chargers but are considered a worthwhile investment for regular EV drivers due to their improved efficiency and convenience. They offer a good medium between Slow chargers and Rapid Chargers for optimising your EV battery health. 

To help you navigate the different charging speeds, we’ve detailed the benefits of each in our comprehensive EV Charging Guides.

Example Charging Times

Here’s a handy comparison table to help you understand how different charging outputs and vehicle battery capacities can impact the time it takes to charge your electric car:

Electric Vehicle Approximate Empty-to-Full Charging Time
Model Battery 3.7 kW slow 7 kW fast 22 kW fast
MINI Cooper E 36.6 kWh 10 hours 6 hours 2 hours
BMW i4 eDrive35 67 kWh 19 hours 10 hours 4 hours
Porsche Macan 95 kWh 26 hours 14 hours 5 hours
