A Homeowner's Guide to EV Charger Installation

A home EV charger installation typically costs £700 to £1,000 and can usually be completed in a few hours. This guide covers choosing the right charger, what happens if your consumer unit cannot take the extra load, and why a certified, registered install matters.

More and more drivers across South Wales are switching to electric, and a home charge point is the piece that makes daily driving effortless. Plug in overnight, wake up to a full battery, and forget about queuing at public chargers. This guide walks you through what actually goes into a home EV charger installation, so you know what to expect before you book one in.

Why Charge at Home

Charging at home is almost always cheaper and more convenient than using the public network, especially if you can charge overnight on an off-peak tariff. A dedicated wall-mounted charger is faster and safer than running an extension lead to a three-pin socket, which is never designed for hours of continuous high current.

• Lower running costs: Overnight home charging on a smart tariff can cost a fraction of public rapid charging.
• Convenience: Your car charges while you sleep, so it is ready every morning.
• Safety: A proper charge point is protected, weatherproof and built for the load, unlike a household socket.

Choosing the Right Charger

Most home chargers are 7 kW units, which suit the vast majority of drivers and add a good range overnight. The main choices come down to features rather than speed.

• Tethered or untethered: A tethered unit has the cable permanently attached, which is quick and easy to use. An untethered unit has a socket you plug your own cable into, which keeps things tidy and future proofs you against different connectors.
• Smart features: Many chargers link to an app so you can schedule charging for cheap overnight hours, track usage and set limits.
• Mounting position: Where the charger goes affects both the look and the cable run. We will talk through the neatest option during the quote.

When Your Board Needs a Hand

An EV charger draws a steady, heavy load, so your existing consumer unit needs enough spare capacity to run it safely. During the quote we check your incoming supply and your board.

If your board has room, we wire the charger straight in on its own protected circuit. If it does not, there is no need for a full board upgrade. We fit a separate small consumer unit dedicated to the charger, which keeps everything compliant and protected while avoiding the cost and disruption of replacing your whole board. Either way you end up with a safe, properly protected installation.

What to Expect on the Day

• Survey and agreement: We confirm the charger position, the cable route and the price before starting, so there are no surprises.
• Installation: Most home installs are completed in a few hours. We mount the unit, run the cable neatly and connect it on a properly protected circuit.
• Testing and registration: We test the installation, hand you the paperwork and register the work as required. You get a charge point that works reliably from day one.

Cost Guide

Most home EV charger installations fall between £700 and £1,000 supplied and fitted. The final figure depends on a few things.

• The charger: Smart and tethered units cost a little more than basic models.
• Cable run: A charger close to the board is cheaper than one that needs a long run around the property.
• Board work: If a separate small consumer unit is needed for the charger, that is included in the fixed price we quote.

We always confirm a clear fixed price up front, so you know exactly what you are paying before any work begins.
