UK Guide to Installing a Home EV Car Charger

Summary

• Cost: A home EV charger installation typically costs between £800 and £1,500, including the unit and a standard installation.
• Eligibility: You need off-street parking (like a driveway), permission from your landlord or freeholder if applicable, and a stable Wi-Fi signal.
• Charger Type: A 7kW smart charger is the standard for UK homes, providing a full charge overnight for most electric vehicles.
• Grants: Renters and flat-dwellers can get up to £350 off the cost via the EV Chargepoint Grant, which is handled by the installer.
• Installation: This is not a DIY job. It must be carried out by a qualified and certified electrician, who will also handle required safety checks.

So, you’ve taken the plunge into the world of electric vehicles, or you're seriously thinking about it. Fantastic. But now comes the slightly less glamorous part: how do you actually charge the thing without trailing a cable through your letterbox and hoping for the best?

Getting a dedicated home EV charger, often called a wallbox, is the answer. It's safer, much faster, and way cheaper in the long run than relying on public chargers. But let's be honest, the process can feel a bit daunting. There are costs, grants, different charger types, and a whole load of rules to think about. Don't worry. Grab a coffee, and let's break it down into plain English.

Can You Get a Home Charger?

Before you start picking out colours and features, there are a few non-negotiables you need to tick off.

• Do you have off-street parking? This is the big one. To get a home charger installed, you almost always need a driveway, garage, or some other form of private, off-street parking. Why? Because you can't have cables trailing across a public pavement. It's a trip hazard and a big no-no under the Highways Act 1980. While some clever on-street solutions exist, they're more complicated and require council permission. For most of us, a driveway is key.
• Do you have permission? If you own your house, you're good to go. But if you're renting, you'll need written permission from your landlord before anyone starts drilling holes in the wall. The same goes if you live in a flat – you'll need the green light from the freeholder or property manager.
• Is your Wi-Fi decent? This might sound odd, but since 2022, all new home chargers in the UK must be "smart". This means they connect to the internet to do clever things like scheduling charges for when electricity is cheapest. For that to work, you'll need a stable Wi-Fi or 4G signal where the charger is going to be installed.

How Much Does a Home Charger Cost?

Okay, let's talk brass tacks. The cost of getting a home EV charger installed in the UK typically ranges from £800 to £1,500.

This price usually covers the charger itself and what's known as a "standard installation."

A standard installation generally includes:

• Fitting the charger to a brick or plaster wall.
• Up to 10 metres of cable running from your fuse box (consumer unit) to the charger.
• Drilling through one wall.
• Fitting and testing all the necessary safety equipment.

However, life isn't always "standard," is it? The price can climb if your setup is a bit more complex. Things that can add to the cost include:

• Needing a longer cable run (more than 10-15 metres).
• Having to run the cable underground (which means digging a trench).
• Needing to upgrade your main fuse or the consumer unit itself. If your fuse box looks like something from a black-and-white film, you might be looking at an extra few hundred quid.

Government Grants for EV Chargers

There's good news and bad news here. The bad news is that the main government grant (the EVHS) for homeowners in houses ended back in 2022.

But the good news is that the EV Chargepoint Grant is still available for certain people until at least March 2026. You could get up to £350 (or 75% of the total cost, whichever is lower) off your installation if you:

• Live in a flat (whether you own it or rent it).
• Rent any kind of residential property (a house, bungalow, etc.).

There are also grants available for landlords who want to install chargers at their properties. The key thing to remember is that you can't claim the grant yourself. The OZEV-approved installer you use will handle the paperwork and deduct the grant amount from your final bill. For a deeper dive, check out our complete guide to car grants.

Which Charger Should You Get?

Walk into this world blind and you'll be hit with terms like kW, tethered, and three-phase. It’s simpler than it sounds.

Charging Speeds Explained

• 3-pin plug (around 2.3kW): You can charge your car from a regular wall socket, but it's a terrible idea for anything other than an emergency top-up. It’s painfully slow – we’re talking 24 hours or more for a full charge. Plus, it puts a massive strain on your home's wiring, which isn't designed for that kind of sustained load. Avoid.
• 7kW Chargers: This is the sweet spot and the standard for home charging in the UK. A 7kW charger will add about 25-30 miles of range per hour, meaning it can easily fully charge pretty much any EV overnight. It works with a standard single-phase electricity supply, which is what 99% of UK homes have.
• 22kW Chargers: These are much faster, but there's a huge catch: they require a three-phase electricity supply. Most homes don't have this, and getting it installed can cost thousands and involve a lot of hassle with your local network operator. Honestly, for home use, it's usually overkill.

Tethered vs. Untethered

This is a simple choice, a bit like a built-in phone charger versus a separate cable.

For most people, the convenience of a tethered charger wins out.

The Installation Process

Let's be crystal clear about this: you cannot install an EV charger yourself. It's a complex, high-voltage job that needs to be done by a qualified and certified electrician.

An installer should be registered with a scheme like NICEIC or NAPIT and, ideally, be OZEV-approved if you're hoping to claim a grant.

Here’s what the process generally looks like:

1. Choose your installer: You can either buy a charger and find an installer separately, or (more commonly) go with an installation package from a single company.
2. The Survey: They'll ask you to fill out an online form with photos of your fuse box, electricity meter, and where you want the charger. This helps them figure out if it's a standard job or if extra work is needed.
3. DNO Approval: The installer will contact your local Distribution Network Operator (DNO) – the company that manages the electricity grid in your area. This is a legal requirement to make sure the local network can handle the extra load. This can sometimes take a few weeks.
4. Installation Day: The electrician will arrive, run a dedicated cable from your consumer unit to the charger location, fit all the safety gear, and mount the unit on the wall. A standard installation usually takes 2-4 hours.
5. Testing and Handover: They’ll test everything to make sure it's safe, show you how it works, and help you set up the app. You should receive an electrical safety certificate after the job is done.

One Last Thing Before You Buy...

Choosing the right charger is important, but making sure you're buying the right car is even more critical. If you're looking at a used EV, its battery health, charging history, and overall condition are vital. A quick check can reveal a lot about a vehicle's past. And speaking of checks, it’s always wise to look under the bonnet, so to speak. Before committing to any used car, electric or otherwise, discover Car Owl's car history check to make sure there are no hidden surprises waiting for you. It's a small step that can save you from a massive headache down the road.

So there you have it. Installing a home EV charger isn't as scary as it first seems. It boils down to a few key steps: check you’ve got the right spot, find a good installer, pick a 7kW charger that suits your style, and let the professionals handle the rest.

Soon you'll be waking up every morning to a "full tank," ready to hit the road without ever having to visit a petrol station again. Welcome to the future.
