Thinking about buying an electric vehicle, but not sure if your home’s wiring can handle a fast charger? You’re not alone!

​Last week, our team was in Grantham helping a customer prepare for the arrival of their new EV. Here is a quick look at what the job involved and why a quick electrical check beforehand is so important.

​The Challenge

​The customer wanted a 7kW smart home charger installed on their driveway for fast overnight charging. However, during our initial site assessment, we spotted an issue: the home’s main consumer unit (fuse box) was an older model without modern RCD safety protection.

​Plugging a high-power EV charger into an outdated board isn’t just inefficient—it can be a serious fire and shock hazard.

​The Solution

​Before fitting the charger, we upgraded the customer’s fuse box to a modern metal consumer unit equipped with Surge Protection Devices (SPD) and Type A RCDs.

​Once the board was fully safe and up to current regulations, we installed the sleek wall charger right next to the driveway, hiding all cables neatly along the brickwork.

​What we completed in a single day:

• ​Upgraded the old fuse box to a modern, fully compliant unit.
• ​Installed a 7kW smart EV charger with smartphone app control.
• ​Conducted full safety testing and issued an Electrical Installation Certificate.

​The Result

​Our customer can now charge their car from 0% to 100% overnight using cheap off-peak electricity tariffs—saving hundreds of pounds a year compared to petrol.
