Home EV charger installation

Installing an electric vehicle (EV) charger at home is a crucial step towards convenient and cost-effective transport. It allows you to power your vehicle efficiently, integrating seamlessly into your home's energy management.

Why install an EV charger at home?

Home EV charging offers significant benefits beyond just convenience, giving you greater control over your energy use and expenses.

Convenience and cost savings

Charging your electric vehicle at home means you can start each day with a full battery, removing the need for regular trips to public charging stations. This routine is generally more convenient and often cheaper than relying on public infrastructure, where costs can be higher, particularly for rapid chargers. With a home setup, you can substantially reduce your overall running costs compared to petrol or diesel vehicles.

Smart charging benefits

New domestic EV charge points sold in the UK since June 2022 are legally required to include smart functionality. This means your charger can do more than just supply power; it can optimise when and how your car charges. Smart features allow you to schedule charging during off-peak hours when electricity is cheaper, or even integrate with solar panels and home batteries to maximise the use of renewable energy. This intelligent approach helps you manage your energy usage and costs, making your home a more efficient energy hub.

Understanding EV charger types

Choosing the right EV charger involves understanding the different types available and how they suit your home's electrical capacity and charging needs.

Slow, fast, and rapid chargers

Home EV chargers primarily come in two types:

• Slow chargers: These typically operate at 3.6 kW, often using a standard three-pin plug. Charging a large EV battery this way can take a long time.
• Fast chargers: Most common for home use, these are typically 7.4 kW. A 7.4 kW charger can add approximately 20-30 miles of range per hour. For a typical 60 kWh electric car battery, this means a full charge from empty can take around 6-8 hours, making it ideal for overnight charging.

While faster 22 kW chargers exist, most UK homes have a single-phase electricity supply, which limits home charging to around 7.4 kW. Upgrading your home's power supply to accommodate three-phase power for a 22 kW charger can be expensive, typically ranging from £2,000 to over £15,000.

Tethered vs untethered units

When selecting a charger, you'll also find tethered and untethered options:

• Tethered chargers: These have a cable permanently attached to the unit, offering convenience as you don't need to retrieve your car's charging cable each time.
• Untethered chargers: These come with a socket, allowing you to use your vehicle's own charging cable. This offers more flexibility if you change cars or if different vehicles with varying charging port types need to use the same charger.

The home EV charger installation process

Installing an EV charger is a professional job that ensures safety and compliance with UK electrical standards.

Initial assessment and site survey

Before installation, a qualified installer will conduct an initial assessment of your home. This involves evaluating your property's electrical capacity, checking the distance from your fuse box to the desired charger location, and assessing parking arrangements. They will determine if any electrical upgrades are necessary to safely support the new charger.

Electrical requirements and upgrades

All EV charger installations in the UK must comply with the latest IET Wiring Regulations (BS 7671). Specifically, Section 722 of BS 7671 outlines the electrical safety requirements for EV charging installations, including dedicated circuits, RCD protection, and surge protection. Your installer will ensure these standards are met. If your home's electrical system requires upgrades, such as a new consumer unit or an earth rod (often needed for outdoor installations), these will be factored into the overall cost and installation plan.

What to expect on installation day

A typical home EV charger installation usually takes between two to four hours. The installer will mount the charge point, run the necessary cabling, connect it to your home's electricity supply, and configure the smart features. They will also test the unit to ensure it's working correctly and safely. Upon completion, you should receive an Electrical Installation Certificate.

EV charger installation costs and grants

Understanding the financial aspects of EV charger installation, including potential grants, is key to making an informed decision.

Factors influencing installation price

The average cost for home EV charger installation in the UK typically ranges from £800 to £1,200, excluding any grants. This price usually includes the charger unit and labour. However, several factors can influence the final cost:

• Charger type: Higher-powered chargers generally cost more to buy.
• Complexity of installation: Longer cable runs, the need for trenching (which can cost around £30 per metre), or significant electrical upgrades will increase the price.
• Labour costs: Electrician rates typically range from £45-£60 per hour or around £400 per day.

Government grants and eligibility

The Office for Zero Emission Vehicles (OZEV) provides grants for specific groups to help with the cost of installing a home charging point. The EV Chargepoint Grant for renters and flat owners provides up to £500 towards installing a chargepoint at the property. To be eligible, you must own and live in a flat or rent any residential property, and have private off-street parking. Similarly, the EV Chargepoint Grant for households with on-street parking provides up to £500 for installing a cross-pavement solution if you only have on-street parking.

It is important to note that owner-occupiers in a house with private off-street parking are not eligible for any current domestic chargepoint grant. Customers must apply for the grant themselves via the GOV.UK website; the installer's role begins only after the application is approved. It's crucial to check your eligibility before purchasing, as the grant cannot be applied retrospectively.

Long-term savings with smart charging

While there's an upfront cost, installing a home EV charger, especially a smart one, leads to long-term savings. By charging during off-peak hours with a smart tariff, you can significantly reduce your electricity costs. For context, the average UK home uses around 2,500 kWh of electricity per year (Ofgem's medium typical domestic consumption value, effective 1 July 2026)1. Optimising your EV charging can make a substantial difference to your overall energy expenditure, empowering you to manage your home energy more effectively.

Choosing the right EV charger and installer

Making the right choices for your EV charger and its installation ensures a safe, efficient, and cost-effective charging experience.

Key features to consider

When selecting an EV charger, consider these features:

• Charging speed: A 7.4 kW fast charger is generally the most practical and cost-effective choice for most homes.
• Tethered or untethered: Decide whether a fixed cable or a socketed unit best suits your needs and potential future vehicles.
• Smart functionality: Ensure the charger has smart features for scheduling, remote control, and integration with energy tariffs to maximise savings.
• Compatibility: Check that the charger is compatible with your electric vehicle and any existing home energy systems like solar panels or batteries.

Finding a qualified and OZEV-approved installer

The installation of an EV charger is a critical task that must be carried out by a qualified and certified electrician. To administer any applicable government grants, installers must also be approved by the OZEV. Choosing an OZEV-approved installer ensures compliance with safety regulations and eligibility for grants.

This professional expertise, combined with continuous support, provides peace of mind throughout your EV charger installation journey and beyond. It's an easy home energy upgrade that contributes to a future with power to play with, integrated into a broader smart home energy ecosystem.
