Frequently Asked Questions

How much does it cost to install a home EV charger?

The cost varies based on factors such as the type of charger, installation complexity, and any necessary electrical upgrades. On average, installation costs range from £800 to £1049. The OZEV grant can offset up to £350 of this cost.

To install a home EV charger, homeowners must first get approval from their Distribution Network Operator (DNO). We will manage this DNO application for you as part of the installation. Renters, on the other hand, will need permission from both their local DNO and their landlord before the installation can go ahead.

The ideal location for your home EV charger is a wall situated close to where you typically park your car, allowing the charging cable to connect to your vehicle’s charging point without difficulty.

We typically aim to have your home EV charger installed and operational within 1 to 3 weeks after we receive your payment.

No, a smart meter is not required before we install your EV charger, and you can still use the charger without one. However, if you’re considering taking advantage of EV-specific energy tariffs offered by UK providers, a smart meter will be necessary to benefit from those plans.

A standard installation, which includes commissioning your EV charge point, usually takes around 3 hours. We’ll confirm your specific installation package and timeframe with you during the process. Typically, up to 90% of installations are standard.

Home EV chargers come in different power levels, primarily affecting charging speed: 

–  7kW: Suitable for most homes, providing a full overnight charge. 

–  11kW & 22kW: Offer faster charging but need three-phase power. 

Our team can advise you on the best charger for your vehicle and home electricity supply.

We take care of the entire OZEV grant application process for you. Here’s how it works:

  1. Eligibility Check: We review your details to confirm your eligibility and collect the required documentation.
  2. Application Submission: Our team submits your application directly to OZEV.
  3. Approval & Installation: Once approved, we move forward with scheduling and completing your installation.

Installing a home EV charger will lead to higher electricity usage and a larger bill. Nevertheless, for many, the cost of charging an EV is still lower than the expense of fueling a traditional petrol or diesel vehicle. Charging during off-peak hours can also help to minimise these costs.

For your safety and the proper functioning of your EV charger, installation must be performed by a qualified and competent electrician. We want to assure you that all of our engineers are fully qualified and highly competent in handling EV charging installations.

A standard installation, representing up to 90% of our installations, encompasses the provision of up to 10 meters of cabling, a residual current device (RCD) with appropriate enclosure, any necessary supplementary materials, and the complete installation, commissioning, and Wi-Fi configuration of the electric vehicle charging point.

Occasionally, an EV charger installation may be classified as non-standard (this happens in about 10% of cases). This just means that the installation will require some extra materials and a bit more work to complete properly. Because of this, the price for a non-standard installation will be adjusted accordingly. Examples of what can make your installation non-standard include if your fuse box/meter isn’t on an outside wall, if the cable needs to run more than 10 meters, or if we need to bury the cable in the ground or under paving.
