Am I EV Ready? Check If Your Home Can Handle a Charger

Can Your Home Handle an EV Charger?

Thinking about getting an electric vehicle or just bought one? Before you book an installation, there are a few things that determine whether your home is ready for a dedicated EV charger, or whether it needs some preparation first.

Use this quick check to find out where you stand. Most homes can have an EV charger fitted, but some need electrical upgrades first. Better to find out now than on installation day.

1. Check your fuseboard

Your EV charger needs its own dedicated circuit, which means a spare way in your consumer unit. Open your fuseboard cupboard and take a look:

Modern board with trip switches (MCBs)? Good start. Check if there is a spare slot. If there is, you are probably fine. If every slot is taken, the board may need upgrading or extending.

Old board with rewirable fuses or a wooden back? This will need replacing before an EV charger can be installed. An old board cannot safely handle the additional load. See our page on whether your fuseboard is safe.

Not sure? WhatsApp us a photo of your fuseboard and we will tell you in minutes.

2. Check your main fuse size

Your electricity supply has a main fuse (sometimes called the service head or cut-out fuse), which limits how much power your home can draw at once. Most UK homes have a 60A or 100A supply.

100A supply? You can usually run a 7kW charger without any issues alongside your normal household usage.

60A supply? You may still be able to have a charger installed, but it might need to be load-managed or set to charge at a lower rate during peak usage. Some chargers like the Zappi and Ohme can do this automatically.

Not sure what you have? Your electrician will check this during the site survey. Or WhatsApp us and we will explain what to look for.

3. Check your earthing

EV chargers require a TN-S or TN-C-S earthing system. Most modern homes have this, but some older properties, particularly those with TT earthing (an earth rod in the ground), may need upgrades to meet the requirements for EV charging.

This is something we check during every site survey. If your earthing needs upgrading, we will include it in the quote, so you know the full cost before we start.

4. Think about your cable route

The charger needs cabling from your fuseboard to the mounting location. Think about:

Where will you park? The charger should be as close to where you park as possible. A driveway right outside your house is ideal.

How far is your fuseboard from the charger location? Longer cable runs cost more and take more time. If your fuseboard is at the back of the house and you want the charger at the front, the cable needs routing through or around the property.

Do you have a terraced house with no driveway? There are solutions, trailing cable covers, rear access, or community charging, but they need more planning.

5. Choose your charger

The most popular home EV chargers in the UK right now are:

Zappi: the most popular choice. Smart tariff integration, solar compatibility, load management built in. Read our Zappi guide.
