How Much Does Electric Car Charger Cost

As more UK drivers make the switch to electric vehicles, one of the first questions they ask is how much it costs to install an electric car charger at home. While public charging is available across the country, most EV owners find that having a home charger is the most convenient and cost effective option. The price of buying and fitting a charger depends on several factors including the type of charger, the complexity of the installation and any additional electrical work required to ensure safety and compliance.

Understanding the Different Types of Electric Car Chargers

There are two main categories of chargers for home use. The first is a standard three pin plug which connects directly to a household socket. While this is the cheapest option, it is slow and not recommended as a permanent solution because it can place strain on the home wiring. The second and far more popular option is a dedicated wall mounted charge point, usually rated at either 7kW or 22kW. A 7kW unit is the most common choice for UK households as it can fully charge most electric cars overnight, making it practical for daily use. A 22kW charger requires a three phase supply, which is not standard in most homes and would add significant cost if an upgrade to the incoming supply was required.

Typical Costs of Electric Car Chargers

The price of a home charging unit itself varies depending on the brand, features and power rating. For a 7kW charger, the unit typically costs between £400 and £800. If you choose a model with smart features such as scheduled charging, energy monitoring or solar panel integration, the cost may be higher. A 22kW charger is usually more expensive, often exceeding £1,000 just for the unit, and it is only suitable for properties with three phase power.

Installation Costs and Additional Work

Fitting the charger involves more than simply fixing it to the wall. A qualified electrician will need to connect it to the consumer unit using suitable cabling and protective devices in line with BS7671 wiring regulations. Installation costs typically range from £400 to £600 for a straightforward job where the charger is mounted close to the consumer unit. If the installation is more complex, for example where the consumer unit is far from the driveway or garage, additional cabling, groundwork or even a consumer unit upgrade may be needed. These factors can increase the total cost, with some installations running to £1,000 or more.

Compliance with UK Regulations

All EV charger installations must comply with Part P of the building regulations and the IET wiring regulations. This means that only a competent, qualified electrician should carry out the work, and the installation should be notified to building control if it is not carried out by a contractor registered with a competent person scheme. The regulations also require protective devices such as residual current devices and, in many cases, surge protection to ensure safe operation. Landlords installing EV chargers for tenants should also ensure compliance with electrical safety standards, including regular inspection and testing.

Government Support and Grants

In recent years, the UK government has provided grants to reduce the cost of home charger installation. The Electric Vehicle Homecharge Scheme previously offered support, though its scope has changed over time and is now more targeted towards landlords and tenants in rental or leasehold properties. Business owners may also be able to access financial support for workplace charging. These grants can reduce the upfront cost significantly, so it is worth checking eligibility before arranging an installation.

Ongoing Running Costs

Once a charger is installed, the main cost is the electricity used to charge the vehicle. This varies depending on the tariff and whether the owner takes advantage of off peak rates. Some smart chargers allow for charging to be scheduled at cheaper times, which can significantly reduce costs over the long term. Maintenance costs are minimal, as modern units are designed to be durable and weather resistant, though they should still be inspected periodically by a qualified electrician to ensure continued safety.

The Value of Professional Installation

Although it may be tempting to look for the cheapest option, the quality of the installation is just as important as the cost. A poorly installed charger can present safety risks, reduce charging efficiency and potentially invalidate warranties. Choosing a contractor registered with a recognised body such as NICEIC or NAPIT provides reassurance that the work will meet UK standards and be carried out safely. In many cases, a professional installer will also handle the notification to building control and provide the necessary certification for the electrical work.

Final Thoughts

The cost of installing an electric car charger in the UK typically ranges from £800 to £1,200 for a 7kW unit, including both the charger and professional installation. The exact figure depends on the type of charger, the complexity of the installation and any additional electrical upgrades required. While this may seem like a significant investment, the convenience, safety and long term savings make it worthwhile for most electric car owners. By ensuring compliance with UK regulations and choosing a competent installer, homeowners and landlords can benefit from a reliable charging solution that adds real value to their property.
