Power Up Your Knowledge: Understanding Building Regulations for EV Charger Installations

As the world shifts towards electric vehicles (EVs), many homeowners are considering installing EV chargers at their homes. In this blog post, we’ll explore the building regulations surrounding EV charger installations and answer some common questions. At Shear Architectural Design, we are committed to providing our clients with the necessary information and guidance for a successful project, whether it’s a new build, house extension, loft conversion, or garage conversion.

The Building Regulations for EV Charger Installations

Part P of the Building Regulations

The installation of an EV charger at home is subject to Part P of the building regulations, which ensures electrical safety in dwellings. The installer must be a registered electrician, such as an EV electrician, and the work must be certified upon completion.

Part S of the Building Regulations

Part S of the building regulations, which concerns the security of dwellings, is also relevant for EV charger installations. Chargers must be securely fixed at a height between 0.75 and 1.2 metres from the ground and be RCD protected. For more information on building regulation plans, visit our building regulations and planning permission page.

DNO Approval for EV Charger Installations

Distribution Network Operator (DNO) approval is required for EV charger installations. To check your DNO approval or apply, consult your local DNO or an EV charge point installer near you. Notify the DNO of your EV charger installation by following their specified process.

Answering Your EV Charger Installation Questions

Are EV chargers AC or DC?

Most home EV chargers are AC (alternating current) chargers, which are typically slower than DC (direct current) chargers found at public charging stations.

Are EV chargers 3 phase?

EV chargers can be single-phase or three-phase. A three-phase charger is more powerful and can charge an EV faster. However, not all homes have three-phase electricity.

Are EV charging cables waterproof?

Yes, EV charging cables are designed to be weatherproof and can be safely used in wet conditions.

Average EV charger installation cost?

The average EV charger installation cost depends on factors such as the charger type, installation complexity, and any additional work required. It’s best to consult an EV charger installation expert for an accurate quote.

Can electrician install EV charger?

Yes, a qualified and registered electrician, like an EV electrician, can install an EV charger at your home.

Can I install EV charger at home?

Yes, you can install an EV charger at home, provided you meet the necessary building regulations and DNO approval requirements.

Can you install EV charger yourself?

Many homeowners may wonder if they can save some money by installing an EV charger themselves. While it might be tempting to try your hand at a DIY installation, it’s important to understand that EV charger installation is a complex process that involves working with high-voltage electrical systems, adherence to building regulations, and ensuring the safety of your home and its occupants.

Attempting to install an EV charger yourself can lead to potential risks, including electrocution, fire hazards, and voiding your home insurance policy or warranty. Furthermore, an improperly installed EV charger may not function efficiently, which can reduce the overall performance and lifespan of your electric vehicle’s battery.

In the UK, EV charger installations must comply with the IET Wiring Regulations (BS 7671) and the building regulations outlined in the previous sections. To ensure compliance, a certified electrician or an EV charge point installer near you must carry out the installation. These professionals are trained to follow the necessary safety protocols and regulatory requirements, ensuring a secure and efficient installation.

In short, while it may be tempting to try a DIY installation, it’s crucial to hire a qualified professional for your EV charger installation. By working with a certified electrician or an experienced Architectural Designer, you can ensure the safe and efficient integration of an EV charger into your home, while also adhering to the necessary building regulations.


What is Part S of the Building Regulations?

Part S of the Building Regulations refers to the specific guidelines that apply to the installation of electric vehicle (EV) charging infrastructure. This section aims to ensure that any EV charger installations are safe, efficient, and accessible. Compliance with Part S is vital for a successful EV charger installation.

What Heights Do EV Chargers Need to Be?

The height of an EV charger is essential for accessibility and safety reasons. According to the building regulations, the charging point should be mounted between 0.75 and 1.2 metres from the ground. This height range ensures that the charger is accessible to all users, including those with mobility issues.

Do EV Chargers Need to Be RCD Protected?

Yes, EV chargers must be protected by a residual current device (RCD). An RCD is a safety device that automatically switches off the electrical supply when it detects an imbalance in the current flow, such as a fault or a leakage. This protection is crucial to prevent electric shock hazards and minimise the risk of electrical fires.

Notifying the DNO and Gaining Approval

Before installing an EV charger, you may need to notify your Distribution Network Operator (DNO). A DNO is responsible for maintaining the electrical infrastructure in your area. Some installations require DNO approval, while others only require notification. To check whether you need approval or to notify the DNO of your EV charger installation, you can follow the guidelines provided by your local DNO.

Can a Local Electrician Install an EV Charger?

Yes, a local electrician can install an EV charger, provided they are certified and experienced in EV charger installations. It is essential to choose a qualified electrician who is a member of a recognised trade body, such as the NICEIC or the ELECSA. These organisations ensure that their members adhere to strict safety standards and installation guidelines.
