As electric vehicles (EVs) become more popular across the UK, choosing the right home charger has become just as important as selecting the car itself. One key question many homeowners face when installing an EV charger is whether to go for a tethered or an untethered charger. At RCD Electrical, we help homeowners make informed decisions every step of the way.
Let’s explore the difference between tethered and untethered EV chargers to help you understand which option suits your needs best.
What is a Tethered EV Charger?
A tethered charger comes with a fixed cable that is permanently attached to the charging unit. Think of it as similar to a traditional petrol pump — it’s ready to go when you pull up and plug in. This option offers a high level of convenience, especially if you always charge the same vehicle.
Benefits of Tethered Chargers:
-
Convenience: You don’t have to keep a separate charging cable in your car.
-
Quick to plug in: Just park, unwind the cable, and charge.
-
Neater storage: The cable stays attached to the unit, often with a holster.
Considerations:
-
The cable length is fixed, usually around 5 to 7.5 metres.
-
Not ideal if you own or plan to buy multiple EVs with different connector types.
What is an Untethered EV Charger?
An untethered charger, sometimes called a ‘socket-only’ charger, has no built-in cable. Instead, you connect your own charging cable to the unit, much like plugging in a household appliance.
Benefits of Untethered Chargers:
-
Flexibility: Compatible with different EVs and connector types.
-
Tidy look: Without a fixed cable, the unit can appear sleeker.
-
Easy to upgrade: You can switch cables or replace them easily if needed.

Which One Should I Choose?
This decision comes down to your lifestyle and preferences. If you want plug-and-go simplicity and always charge the same EV, a tethered charger might be best. If you value versatility and plan to change your EV in the future, an untethered charger offers more flexibility.
