A Mid Devon Homeowner's Guide to EV Chargers

A home EV charger typically costs £1,000 to £1,600 installed and can usually be fitted within around 10 days. This guide covers the difference between tethered and untethered chargers, why your consumer unit and supply need checking first, and why the installation must be carried out and certified by a registered electrician.

More and more Mid Devon drivers are switching to electric and plug-in hybrid cars, and the single biggest change most of them notice is how they refuel. Instead of trips to the forecourt, you plug in on the driveway and wake up to a full battery. A dedicated home charge point makes that simple, safe and far cheaper than public charging. This guide walks through what is involved, what it costs, and what to look for in a good installation.

Why Charge at Home

A three-pin plug in the garage is not a safe long-term way to charge a car. A dedicated EV charge point is designed for the sustained current an electric car draws, sits on its own protected circuit, and charges far faster than a standard socket.

• Lower cost: Home electricity, especially on an off-peak overnight tariff, is a fraction of the price of public rapid chargers.
• Convenience: Plug in when you get home and let the car charge overnight. No detours, no queues, no apps to juggle.
• Speed: A 7 kW home charger typically adds a full charge overnight, far quicker than a standard 3-pin socket.
• Safety: A proper unit has its own circuit and protective devices, so it is built for the job rather than borrowing a socket that is not.

Tethered or Untethered

There are two main styles of home charger, and the right one comes down to how you like to use it.

• Tethered: The cable is attached to the unit, so you just grab it and plug in. Quick and tidy day to day, but you are fixed to that cable length and connector type.
• Untethered: You use your own cable and plug it into the unit each time. It keeps the wall unit neat, works with any connector, and is handy if more than one type of car uses the driveway.

Most single-car households prefer tethered for the convenience. We are happy to talk through both and recommend what suits your car, your driveway and your budget.

Checking Your Supply

Before any charger goes on the wall, your electrical supply needs a proper look. This is the part cut-price installers skip, and it is exactly what keeps your installation safe and compliant.

• Main supply: We confirm your incoming supply can take the extra load of a charger alongside everything else in the house.
• Consumer unit: We check your fuse board has room and the right protection, and flag it early if an upgrade would make sense first.
• Cable route: We plan the neatest run from the board to where you want the charger, so the finished job looks tidy rather than an afterthought.
• Earthing: EV chargers have specific earthing requirements, and we make sure yours are met with the correct protective device.

Cost Guide

A home EV charge point installed by SJ Electrical Services typically costs between £1,000 and £1,600 supplied and fitted. The final figure depends on a few things.

• The charger: Different units and smart features sit at different price points.
• Cable run: A short run from a board near the driveway costs less than a long route across the house.
• Any upgrades: If your consumer unit needs attention first, we will price that separately and clearly so there are no surprises.

Whatever the job, you get a clear fixed quote up front, with no hidden extras added on the day.

Why Certification Matters

An EV charger installation is notifiable electrical work. It has to be carried out and certified by a registered electrician, and that certification is your proof the job was done and tested properly.

• Safety: A registered electrician installs the dedicated circuit and protective devices correctly, and tests the finished installation.
• Compliance: As a NAPIT registered electrician, Stewart self-certifies the work, so it is signed off in line with current wiring regulations.
• Peace of mind: You are left with the right paperwork, which matters for insurance, for any future sale, and simply for knowing it was done right.

Always check your installer is registered before work starts. SJ Electrical Services is NAPIT registered, and every EV charger we fit is tested and certified.
