Your Ultimate Guide to Installing a Compliant Home EV Charging Station in the UK

Why You Need a Home EV Charging Station

As the world shifts towards more sustainable and environmentally friendly transportation, owning an electric vehicle (EV) is becoming increasingly popular. One of the key benefits of an EV is the convenience of charging it at home, eliminating the need for frequent visits to public charging stations. However, to fully leverage this convenience, you need to install a home EV charging station.

“Installing a home charging point makes owning an electric car so much easier and cheaper,” notes the RAC. This is because home charging allows you to take advantage of cheaper energy tariffs and ensures your car is always ready to go when you need it[2].

Types of Home EV Charging Stations

When it comes to choosing a home EV charging station, you have several options, each with its own set of benefits and considerations.

Level 1 Charging Stations

Level 1 charging stations use a standard 230-volt outlet and are the slowest type of charger. They are often included with the purchase of an EV and can be used for emergency or occasional charging. However, they are not ideal for regular use at home due to their slow charging speed.

Level 2 Charging Stations

Level 2 charging stations are the most common choice for home installations. They require a 240-volt circuit and can charge your EV much faster than a Level 1 charger. For example, a Level 2 charger can recharge an EV battery in about a quarter of the time it would take with a Level 1 charger[3].

Level 3 Charging Stations

Level 3 charging stations, also known as DC Fast Chargers, are the fastest type but are not typically installed at home due to their high cost and the need for significant electrical infrastructure upgrades. These chargers are usually found at public charging stations along highways and in shopping centers.

Choosing the Right Charger for Your Home

Power Requirements

Before installing a charger, you need to determine the power requirements of your EV. Most homes have a single-phase electricity supply, which limits the charging speed to 7kW. However, some homes may have access to three-phase electricity, allowing for faster charging speeds of 11kW or 22kW, provided your EV can handle it[2].

Tethered vs. Untethered Chargers

You also need to decide between a tethered and an untethered charger. A tethered charger comes with a cable attached, which can be convenient but may become obsolete if the industry moves away from the current socket types. An untethered charger looks tidier but requires you to supply your own cable[2].

Installation Process and Requirements

Pre-Installation Checks

Before starting the installation, it’s recommended to get an electrical survey of your home to ensure your wiring can handle the increased power demand. Your electrician will check the quality of your home wiring and may recommend upgrades such as improving the earthing connection, increasing the wire size between your fuse board and electricity meter, or improving the electrical bonding between metal pipes[1].

Qualified Electrician

The installation must be performed by a fully qualified electrician who is registered with Safe Electric Ireland or a similar regulatory body in the UK. This ensures that the work is done safely and to the required standards[1].

Grant and Funding

In the UK, you may be eligible for grants to help cover the cost of installing a home charger. For instance, the Electric Vehicle Home Charger Grant in Ireland (and similar schemes in the UK) provides financial support for residents to install a charge point at their home. However, there are specific requirements, such as the EV being parked on an off-street parking location associated with the home, and the charger must be connected back to the home of the applicant[1].

Cost Considerations

Charger Costs

The cost of a home EV charging station can vary widely. Level 2 charging stations, which are the most common, can start at around £300 and can exceed £1,000 for a sophisticated, hard-wired, wall-mounted unit. Additionally, you may need to hire an electrician and possibly upgrade your home’s electrical system, which can add another £1,000 to £2,000 to the total cost[3].

Installation Costs

The installation cost itself can also vary. Here is a rough breakdown of what you might expect:

Component Cost Range
Level 2 Charger £300 – £1,000
Electrician’s Labor £500 – £1,500
Electrical System Upgrades £500 – £2,000
Total Estimated Cost £1,300 – £4,500

Ongoing Costs

Besides the initial installation cost, you also need to consider the ongoing cost of electricity. However, charging your EV at home can be significantly cheaper than using public charging stations. Smart chargers can help you take advantage of cheaper energy tariffs by charging your car when energy supply is high but demand is low[2].

Practical Tips for Installation

Choosing the Right Location

When deciding where to install your charging point, consider several factors:

  • Visibility and Aesthetics: Do you want the charger to be hidden or on view? This can affect whether you choose a tethered or untethered charger.
  • Charging Port Location: Ensure the charger is conveniently located near the charging port of your EV.
  • Cable Length and Safety: Factor in the length of the charging cable to avoid trip hazards.
  • WiFi Access: If you opt for a smart charger, ensure it has access to your home WiFi signal for remote charging and energy tariff management[2].

Compliance with Regulations

Ensure that your installation complies with local regulations. For instance, if your installation requires a new permanent structure or extends beyond the boundaries of your property, you may need to seek a declaration from your local planning authority or obtain full planning permission[1].

Benefits of Smart Chargers

Smart chargers offer several benefits that make them a popular choice for home installations:

  • Energy Efficiency: Smart chargers can optimize charging times based on energy tariffs, ensuring you charge your car when electricity is cheapest.
  • Remote Control: You can control and monitor your charger remotely through an app, allowing you to start or stop charging sessions and check the charging status.
  • Integration with Home Energy Systems: Smart chargers can integrate with your home energy system, allowing for more efficient use of renewable energy sources like solar panels.

“Smart home chargers will also allow you to take advantage of cheaper energy tariffs, charging the EV when supply is high but demand is low,” explains the RAC[2].

Installing a home EV charging station is a significant step in making your electric vehicle ownership experience seamless and cost-effective. By understanding the different types of chargers, the installation process, and the cost considerations, you can make an informed decision that suits your needs.

Remember, “the electricity to recharge the vehicle has to come from somewhere,” and having a home charging station ensures that you can recharge your EV conveniently and efficiently[3].
