Understanding the differences: tethered vs untethered EV chargers

At its heart, the distinction between a tethered and untethered EV charger lies in the charging cable itself. This fundamental difference shapes how you interact with your charger every day.

Tethered chargers: convenience and fixed cables

A tethered EV charger comes with a charging cable permanently attached to the unit. Think of it like a petrol pump - the hose is always there, ready to go. For many, this offers unparalleled convenience. You simply pull up, grab the cable, plug it into your car, and charging begins. There's no need to retrieve a cable from your boot, uncoil it, or store it away afterwards.

Most tethered units in the UK come with a Type 2 connector, which is the standard for European EVs. The cable length is fixed, typically between 5 and 10 metres, so it's crucial to consider your parking spot and the charging port location on your vehicle. The main advantages are ease of use and a potentially tidier setup if the cable is neatly coiled on the unit or a hook.

Untethered chargers: flexibility and your own cable

An untethered EV charger, often called a 'socket-only' charger, doesn't have a built-in cable. Instead, it features a universal Type 2 socket. This means you use your own charging cable - the one that usually comes with your EV, or one you purchase separately.

The key benefit here is flexibility. You can use different cable lengths, or even a different cable if you have visitors with an EV that requires a specific type (though Type 2 is now standard for most AC charging). It also offers a cleaner, more minimalist aesthetic on your wall, as there's no cable hanging down when not in use. If you frequently use public charging points that require you to bring your own cable, an untethered unit means you're already in the habit of handling your cable.

Key considerations for UK EV owners

Deciding between a tethered vs untethered EV charger for your UK home involves more than just convenience. It's about practicalities, future-proofing, and understanding the nuances of home charging.

Practicalities: daily use, installation and future-proofing

When making your choice, consider your daily routine. Do you want the ultimate grab-and-go convenience of a tethered unit, or are you happy to manage a separate cable for the flexibility an untethered EV charger offers?

• Daily Use: With a tethered charger, the cable is always there, ready to plug in. For an untethered unit, you'll need to get your cable out and put it away each time. This might seem minor, but it can add up over time, especially in bad weather.
• Installation: Both types require professional installation by a qualified electrician. The UK government's OZEV (Office for Zero Emission Vehicles) grant can help reduce the upfront cost for eligible homeowners. This grant provides up to £500 off the cost of purchasing and installing a home charging point. To be eligible, you typically need to live in a flat or rented property with dedicated off-street parking, and own an eligible EV. Consider the charger's location and how the cable will reach your car's charging port. A fixed cable needs to be long enough, while an untethered unit allows you to swap cables if your parking habits change.
• Future-Proofing: While Type 2 is the standard an untethered charger offers more adaptability if future EV models introduce new cable requirements or if you upgrade to a car with a charging port in a different location. However, a well-placed tethered unit with a sufficiently long cable should serve you well for years to come. All new home EV chargers sold in Great Britain must be 'smart' and adhere to specific regulations, ensuring they can be updated and managed efficiently. These regulations, which came into force on 30 June 2022, require smart functionality1, including the ability to schedule charging during off-peak hours and a randomised delay function.
