Installing an electric vehicle (EV) charger at home or work offers convenient, reliable charging. However, mistakes during installation can lead to electrical hazards, poor performance and unexpected expenses.
What are the most common EV charger installation mistakes? They include choosing an unsuitable charger, overlooking electrical capacity, incorrect wiring, inadequate safety protection and poor charger positioning. Hiring a qualified EV charger electrician helps prevent these issues through proper planning, installation and testing.
At Certified Electricians London, we provide professional EV charger installation in London for homeowners and businesses. Our experienced electricians assess each property's requirements to deliver safe, efficient charging solutions.
1. Choosing the Wrong EV Charger
Not every charging point is suitable for every property or vehicle. One common mistake is selecting a charger based solely on price without considering charging speed, electrical supply or everyday driving requirements.
How do you choose the right EV charger?
The right charger depends on your vehicle's charging capabilities, available electrical supply and typical charging habits.
For example, a 7kW home EV charger is a popular option for properties with a suitable single-phase supply, while higher-powered chargers may require three-phase electricity.
As experienced EV charger installers, we assess your requirements and recommend suitable charging equipment. We are also MyEnergi Zappi installation partners, offering smart charging solutions for customers interested in managing their electricity consumption.
2. Overlooking the Property's Electrical Capacity
An EV charger places additional demand on a property's electrical system. Installing one without checking the existing supply could result in overloaded circuits or electrical problems.
Can your home's electrical system support an EV charger?
Many properties can accommodate a home charging point, but a professional electrical assessment is essential.
At Certified Electricians London, we check the electrical supply, consumer unit and existing demand before recommending an installation. Where necessary, we can advise on consumer unit upgrades or load management solutions to help accommodate charging safely.
3. Incorrect Wiring and Inadequate Electrical Protection
Poor wiring and unsuitable protective devices are serious EV charger installation mistakes. Incorrect cable sizing, inadequate connections or missing safety protection can increase the risk of overheating and electric shock.
Professional EV charger installation requires appropriate circuit design, earthing arrangements and protective equipment.
Why is a qualified EV charger electrician important?
A competent electrician understands the technical requirements involved in safely installing charging equipment.
Our NICEIC-approved team follows applicable electrical safety standards, including BS 7671 wiring regulations. We select suitable cables and protective devices, assess earthing requirements and test installations before they are put into service.
This helps ensure your EV charging point operates safely and reliably.
4. Installing the Charger in an Unsuitable Location
Charger positioning affects convenience, accessibility and installation costs. A poorly positioned charging point may require unnecessarily long cables or create obstacles around a driveway or parking area.
Before installation, consider where your vehicle normally parks, the position of its charging socket and the distance from the electrical supply.
Where should an EV charging point be installed?
Ideally, it should be positioned somewhere accessible, protected from avoidable damage and convenient for everyday charging.
Our electricians assess available installation locations, suitable cable routes and charger accessibility. Whether you require a driveway charger, garage installation or commercial charging point, we help identify a practical arrangement for your property.
5. Ignoring Smart Charging Features
Choosing a charging point without considering smart functionality can limit opportunities to manage electricity usage effectively.
Modern smart EV chargers can offer features such as scheduled charging, energy monitoring and compatibility with certain renewable energy systems.
For example, scheduling charging during cheaper off-peak electricity periods may help reduce running costs, depending on your tariff.
At Certified Electricians London, we help customers understand available smart charging options and select equipment suited to their requirements.
6. Skipping Installation Testing and Certification
Another common mistake is assuming an EV charger is ready to use as soon as it has been connected.
What checks should an electrician carry out after installation?
A professional electrician should complete appropriate electrical inspections and tests, verify the operation of protective devices and confirm that the charging equipment functions correctly.
Depending on the installation, electrical certification and building regulations notification may also be required.
Our electricians carry out the necessary testing and provide relevant electrical certification, giving customers confidence in their new charging installation.
7. Choosing an Inexperienced Installer
Attempting DIY installation or hiring someone without suitable EV charging experience can create unnecessary safety risks and potentially expensive remedial work.
EV charging equipment has specific installation requirements that differ from those of ordinary household sockets.
An experienced installer can identify potential complications early, explain the necessary work and recommend suitable solutions.
