A tethered EV charger has a charging lead permanently attached. An untethered charger has a socket for a separate lead. Both can provide a convenient home charging arrangement when the equipment and installation suit the property; the better choice often comes down to how you park and handle the cable.
GB Electrical Services helps homeowners consider those practical details before selecting equipment. Here is what to think about when choosing between the two formats, without assuming that one is best for every car or driveway.
Tethered: a lead ready beside the car
With a tethered unit, the lead stays at the charge point. That can make arriving home straightforward: the cable is already there rather than stored in the boot or garage. The trade-off is that it still needs a sensible place to sit when the car is not connected.
Check the proposed cable length against the car's normal parking position and charging-port location. Consider the vehicle facing both ways if that is how you use the space. A charger that looks well positioned on an empty driveway may be awkward once the car, bins or another vehicle are in place.
Questions worth asking
- Will the supplied lead comfortably reach the correct connector on the vehicle?
- Where will the cable be stored between uses?
- Can everyone who needs to charge the car handle and put away the lead?
- Does the arrangement leave normal walking routes and gates clear?
Untethered: a separate cable to connect and store
A socketed charger lets you remove the lead when it is not being used. That may appeal if you prefer the wall area clear of a permanent cable or want to store the lead elsewhere. It also means retrieving, connecting and putting away that separate lead as part of your routine.
Do not assume that a cable is included with every charger or vehicle. Confirm what you already have and that the cable is suitable for the equipment and intended use. If you plan to take the same lead away in the car, consider whether having to bring it back out each time is convenient for your household.
Questions worth asking
- Is a suitable charging cable included, or must it be supplied separately?
- Where can it be kept safely and conveniently between charges?
- Will connecting both ends be comfortable in the proposed position?
- What do the manufacturer's instructions say about use, storage and locking?
Cable format is separate from smart features
Tethered and untethered describe the cable arrangement, not the complete feature set. App controls, connection methods and energy-tariff compatibility depend on the particular product. Compare the actual specifications rather than assuming that a separate lead means a basic charger or a fixed lead means a smarter one. The Energy Saving Trust's smart charging advice explains the distinction and the wider considerations.
Which type charges faster?
Cable format alone does not determine charging speed. The vehicle, charger, suitable cable and electrical supply all matter. Choosing a more powerful unit does not ensure that the car can use the additional output. Give your installer the vehicle details and discuss normal parked time before judging equipment by its headline rating.
Think about the next car, without trying to predict everything
If you know a different vehicle or second EV is likely, mention it while the installation is being planned. The charging port may be in a different position and the cars may share the drive differently. That is a reason to consider reach and layout, not a reason to assume that any charger can accommodate every future vehicle or supply requirement.
What matters more than choosing a side
A suitable mounting point, assessed electrical installation and practical cable route matter whichever type you prefer. Raise shared access, permissions and any outdoor work early. Do not choose a unit first and expect the property to fit around it.
The equipment price is also only one part of the installation cost. A socketed unit may need a separately purchased cable, and either format can involve additional property-specific work. Our installation cost guide explains the main things to compare.
