The Biggest Mistakes People Make When Installing an EV Charger at Home

Installing a home charger should be straightforward, yet a lot of people run into problems that end up costing them more money, more time, and in some cases even create safety risks.

Here are some of the most common mistakes homeowners make when setting up EV charging at home and how to avoid them.

Using a Three-Pin Plug for Everyday Charging

Many EV owners start off by using the standard three-pin plug that comes with the car. While it does the job, it is extremely slow and can sometimes take more than twenty-four hours to fully charge a vehicle. On top of that, a normal socket is not designed for this level of sustained demand, which can put unnecessary stress on your wiring and increase the risk of overheating.

The smarter choice is to install a dedicated EV charger. This reduces charging time dramatically and ensures the electrical load is handled safely.

Overlooking the Condition of Your Home’s Wiring

Plenty of homes in Cheshunt and the surrounding areas were built decades before EVs even existed. That means the wiring and consumer units in some properties may not be able to cope with the constant power draw of an electric car. Old or damaged wiring can become a fire hazard if pushed beyond its limits. Before installing a charger, it is important to have a qualified
electrician carry out an Electrical Installation Condition Report (EICR). This check will highlight whether upgrades are needed to make sure your home is safe and ready for charging.

Charging at Peak Hours Without Realising the Cost

A lot of people plug their car in as soon as they get home from work. The problem with that routine is that it usually falls right during peak electricity hours, when prices are at their highest.

Over time, that habit can add a surprising amount to your energy bill. The solution is simple: use a smart charger that allows you to schedule charging overnight when electricity is cheaper.

Once it is set up, you will save money without having to think about it.

Choosing the Wrong Charger for Your Needs

Not all EV chargers are created equal. Some charge slowly, some are not compatible with solar panels, and others lack the smart features that make life easier. Choosing the wrong model could leave you frustrated or limit your options in the future. A professional installer will help you pick a charger that suits your vehicle, your lifestyle, and any plans you may have for upgrades like solar integration. This is one area where expert guidance really pays off.

Cutting Corners on Installation

Trying to save money with a cheap or DIY installation can backfire badly. Poor workmanship may lead to electrical faults, reduced performance, or even invalidate warranties. It also risks leaving you with a charger that is not future-proof for the next generation of vehicles. Working with a qualified installer such as JJB Electrical ensures your system is compliant, safe, and built to last.

Why This Matters in Cheshunt

As more households in Cheshunt and the surrounding areas switch to electric cars, the demand for reliable and safe home charging grows. Making sure your property is properly set up protects your investment, keeps your family safe, and helps you take full advantage of the cost savings that EVs can provide.

Final Thoughts

Driving an EV is a brilliant choice for the environment and for your wallet, but installing the charger in the right way makes all the difference. Avoiding these common mistakes will save you money, keep your home safe, and ensure you get the best performance from your vehicle.
