Before You Install an EV Charger, Check Your Fuseboard First

It’s one of the best upgrades you can make, offering the convenience of charging from your own driveway without having to rely on public stations.

Before you go ahead with the installation, there’s one important thing you should check first: your fuseboard.

Many homeowners assume that adding a charger is simple, but your fuseboard, also known as your consumer unit, plays a major role in keeping your home’s electrical system safe and efficient. If it’s old or not up to standard, it could struggle to handle the added demand of an EV charger.

Why Your Fuseboard Matters

Your fuseboard acts as the control centre for your entire home’s electrical system. It safely distributes electricity to all your circuits, from lighting to appliances. Installing a powerful device such as an EV charger puts extra demand on your system. 

A typical home charger draws around 7.4kW of power, which is the same as running several major appliances at once. If your fuseboard is outdated or already overloaded, it might not be able to cope safely. This can lead to overheating, tripping circuits, or more serious electrical faults.

Common Signs Your Fuseboard Might Not Be Ready

Even if your electrical system seems to be working fine, there may be hidden signs that your fuseboard is not ready for an EV charger. Watch out for the following:

• Old-style fuse wires – If your board still uses wire fuses instead of modern circuit breakers, it’s due for an upgrade.
• No RCD protection – Modern boards include Residual Current Devices (RCDs) that protect you from electric shocks and fire. If your board lacks them, it’s not compliant with current standards.
• Burn marks or a smoky smell – Any discoloration, scorching, or odour near your fuseboard could indicate overheating.
• Frequent tripping – Circuits that trip often can signal that your system is overloaded or nearing capacity.
• No spare space – If all your fuseboard slots are full, there might not be room for an additional circuit for your EV charger.

If you notice any of these issues, it’s a good idea to have your electrical system checked before going any further with your installation.

What a Professional Check Involves

When you schedule an EV charger installation with a qualified electrician, they will begin with a detailed assessment of your current setup.

At JJB Electrical, our electricians will:

• Inspect your fuseboard and confirm it meets current safety standards.
• Check whether there is capacity for a dedicated EV charging circuit.
• Verify your earthing and bonding are suitable for EV charging.
• Recommend any upgrades or repairs needed before installation.

This check ensures that your charger will operate safely and efficiently from day one. If your fuseboard needs upgrading, we’ll explain the best options and give you a clear quote before any work begins.

Why Upgrading Your Fuseboard Is Worth It

Upgrading your fuseboard may feel like an extra cost, but it’s one of the most valuable safety investments you can make.

A modern fuseboard provides stronger protection against electrical faults, supports higher power usage, and prepares your home for future needs. It also improves energy efficiency and ensures your system complies with the latest regulations.

With an upgraded unit, you’ll have peace of mind knowing your EV charger, and the rest of your home, are powered safely.

The Risks of Skipping the Check

Some homeowners are tempted to skip the fuseboard inspection and go straight to installing the charger. This can lead to serious problems later on, such as:

• Constant tripping or blown fuses when charging your car.
• Overheating or electrical fires caused by overloading.
• Invalid home insurance claims if the installation doesn’t meet safety regulations.
• Warranty issues with your EV charger.

Taking the time for a proper check protects your investment and your home.
