EV charger installation cost

Installing an electric vehicle (EV) charger at home typically costs between £800 and £1,200 for a standard 7kW unit, offering a convenient way to power your vehicle and take control of your home energy. This investment can be significantly reduced by available government grants for eligible households and through informed choices about charger type and installer. Understanding these costs and the factors that influence them is the first step towards making a strategic "power play" for energy independence.

Understanding EV charger installation costs

The total cost of installing An EV charger at home is influenced by several factors, from the charger itself to the complexity of the electrical work required. Getting a clear picture of these elements helps in budgeting effectively.

Average costs for home EV chargers

A standard 7kW home EV charger installation in the UK typically costs between £800 and £1,200, including the charger unit and basic fitting. This type of charger is the most common choice for UK homes and can fully charge most average EVs overnight, usually within 8 to 12 hours. A 7kW charger adds around 20–30 miles of range per hour.

Factors affecting installation price

The final price of installing An EV charger can vary based on several key factors:

• Charger type and power output: While 7kW chargers are standard, higher-power chargers (e.g., 22kW) will cost more for both the unit and installation.
• Location and cable run: The distance from your home's consumer unit (Fuse box) to the desired charger location impacts cabling costs. Longer cable runs, especially if they require trenching or drilling through thick walls, increase labour and material expenses. Trenching typically costs around £30 per metre. Groundworks, such as trenching or digger hire, can add £200–£500 to the overall price.
• Electrical upgrades: Older homes or those with consumer units running near capacity may require an upgrade before a charger can be safely installed. A consumer unit replacement typically costs between £300 and £800.
• Smart features: Chargers with advanced smart capabilities might have a higher upfront cost, though these often lead to long-term savings.

Government grants for EV charger installation

Government grants can significantly reduce the cost of installing An EV charger, but eligibility criteria have changed.

The OZEV EV chargepoint grants explained

The Office for Zero Emission Vehicles (OZEV) offers financial support towards the cost of purchasing and installing An EV chargepoint. The EV Chargepoint Grant for renters and flat owners provides up to £500, or 75% off the cost, whichever is lower. Similarly, the EV Chargepoint Grant for households with on-street parking provides up to £500 towards installation costs.

Who is eligible for the grant?

Most typical homeowners are no longer eligible for OZEV domestic chargepoint grants. The Electric Vehicle Homecharge Scheme (EVHS), which previously supported homeowners with private driveways, was discontinued.

The grants are now primarily for:

• Homeowners who live in a flat.
• People living in rented accommodation (including flats or single-use properties).
• Households with on-street parking who are installing a cross-pavement solution (e.g. a charging gully).

To be eligible, you must have dedicated private off-street parking (for renters and flat owners) or only on-street parking (for the cross-pavement solution). You must also own or use an eligible electric or plug-in hybrid vehicle and not have claimed the grant before.

Applying for the grant

If you meet the eligibility criteria for an OZEV domestic chargepoint grant, you must apply for the grant yourself via the gov.UK website. The OZEV-authorised installer's role begins after your application is approved. All EV chargepoint installations must be carried out by an OZEV-authorised installer and comply with IET Wiring Regulations (BS 7671), specifically Section 722 for EV charging installations.

Choosing the right EV charger for your home

Selecting the appropriate EV charger involves considering power output, smart features, and cable type. For more details on charging your electric vehicle at home, you can read our guide on EV charging at home.

7kw vs 22kw chargers

• 7kW chargers: These are the most common and practical choice for most UK homes. They use a single-phase electricity supply, which is standard in residential properties. A 7kW charger can fully charge most EVs overnight, typically within 8 to 12 hours.
• 22kW chargers: These offer faster charging speeds but require a three-phase electricity supply, which is rare in UK homes. Upgrading to a three-phase supply can be very expensive, potentially adding £2,000–£5,000 or more to the installation cost. For most households, a 7kW charger is sufficient for overnight charging without the need for costly electrical upgrades.

Smart charging features and benefits

Since June 2022, all new home EV chargers sold in the UK must be 'smart' under the Electric Vehicles (Smart Charge Points) Regulations 2021/2022. They offer several advantages:

• Lower costs: Smart chargers can be programmed to charge your EV during off-peak hours when electricity rates are lower, significantly reducing your charging expenses.
• Grid stability: By adjusting power delivery in response to grid demand, smart chargers help prevent overloads and support a stable energy supply.
• Control and convenience: You can manage charging sessions remotely via a smartphone app, scheduling charging, monitoring progress, and receiving real-time updates.
• Eco-friendly charging: Some smart chargers can integrate with renewable energy sources like solar panels, optimising charging to use green energy when available.

Tethered vs untethered chargers

• Tethered chargers: These come with a charging cable permanently attached. This offers convenience as you do not need to retrieve your cable from the car every time you charge. However, the cable might not be compatible with All EV models if you change vehicles in the future.
• Untethered chargers: These have a socket where you plug in your own charging cable. This provides flexibility, as you can use different cables for different EVs or replace a damaged cable easily. However, it means you will always need to carry your charging cable with you.

Finding a qualified EV charger installer

The quality of your EV charger installation is as important as the charger itself. Choosing the right professional ensures safety, compliance, and peace of mind.

Why use an OZEV-authorised installer?

All EV chargepoint installations must comply with stringent safety standards, including the IET Wiring Regulations (BS 7671), specifically Section 722 for EV charging installations. OZEV-authorised installers are certified professionals who meet these requirements and are approved to carry out installations. They typically possess formal EV charging point training, such as a Level 3 EV charging qualification, and public liability insurance (minimum £2 million indemnity). Using an authorised installer ensures your installation is safe, legally compliant, and eligible for any available grants.

Key questions to ask potential installers

When obtaining quotes, ask installers the following:

• Are you OZEV-authorised and do you have the necessary certifications and insurance?
• What is included in the quote (charger unit, labour, materials, electrical upgrades)?
• How long will the installation take?
• What warranty do you offer on the charger and the installation work?
• Can you provide references from previous customers?

Getting multiple quotes

It is always advisable to obtain quotes from at least three different qualified and certified installers. This allows you to compare pricing, assess their professionalism, and ensure you are getting a fair deal for the scope of work required. Be wary of quotes that seem significantly lower than others, as they might exclude essential work or use sub-standard materials.

Maximising your EV charging investment

An EV charger is more than just a device to power your car; it is a component of your home's overall energy strategy.

Integrating with home energy management

Framing EV charging as a broader home energy management strategy allows you to gain greater control over your energy usage and costs. Smart chargers, like the Easee One, can integrate with your home's energy ecosystem. This enables you to optimise charging times to align with cheaper off-peak electricity rates or periods of high renewable energy generation, turning charging into a benefit rather than just an expense. This strategic approach empowers you to make a "power play" for energy independence. Homeowners often pair this with a smart meter installation to track usage more effectively.

Long-term savings and benefits

The initial investment in An EV charger yields significant long-term benefits. Charging at home is considerably cheaper than relying on public chargepoints, with off-peak home electricity rates potentially as low as 9–10p per kWh, compared to public charger costs of around 75p per kWh. Over time, these savings add up, making home charging a sound financial decision. Beyond cost savings, home charging offers unparalleled convenience, ensuring your EV is always ready when you need it. By adopting smart charging solutions and integrating them into a wider home energy management system, you contribute to a more efficient and abundant energy future.
