Home EV chargers UK: how to choose an EV charger
Compare the features that matter when choosing a home electric-car charger, including charging power, tethered and untethered cables, smart charging, installation requirements and current OZEV grants.
What is a home EV charger?
A home EV charger, often called a wallbox or chargepoint, provides a dedicated connection for charging an electric vehicle from a residential electricity supply.
Choosing one is not only about the charger itself. The vehicle, electrical supply, parking position, cable route, electricity tariff and installation can all affect which setup makes sense.
What should you compare when choosing a charger?
Tethered vs untethered EV chargers
This can make everyday charging convenient because the cable is already in place when you park.
This can provide a tidier appearance when the charger is not being used and lets the cable be stored separately.
Neither design is automatically better. The choice mainly depends on convenience, appearance, parking position and how you want to manage the charging cable.
How much charger power do you need?
More charging power can reduce charging time, but the number shown on the charger is not the only limit.
The vehicle’s onboard AC charger, the property’s electrical supply and the installation itself can all affect the charging rate that is actually available.
| Example charging power | Best way to think about it |
|---|---|
| 3.5 kW | Lower-power dedicated charging. Charging larger batteries can take considerably longer. |
| 7 kW | A common reference point for residential charging-time comparisons. |
| 11 kW | Requires the vehicle and installation to support the higher AC charging rate. |
| 22 kW | High-power AC charging that requires suitable vehicle and electrical capability. |
Use the EV Charging Time Calculator to compare charging powers using your battery and normal charge range.
Do home EV chargers have to be smart?
Private EV chargepoints sold for use in domestic and workplace environments in Great Britain are covered by the Electric Vehicles (Smart Charge Points) Regulations, subject to the exclusions set out in those regulations.
The rules establish minimum smart functionality and other device-level requirements for covered chargepoints.
See our EV Tariffs UK guide and Smart EV Tariff Savings Calculator .
Do you need solar compatibility?
Some home charging systems can coordinate EV charging with solar generation or other household energy equipment.
Whether that feature is useful depends on your property, solar installation, electricity tariff and when the vehicle is normally at home.
Do not pay for a feature solely because it appears on a specification list. Consider whether you are likely to use it.
What is load balancing?
EV charging can place significant demand on the home’s electrical supply.
A load-management system can monitor or control charging so that EV demand is coordinated with other household electricity use.
The appropriate arrangement is installation-specific and should be assessed by a competent installer.
What affects EV charger installation cost?
The wallbox itself is only one part of an installation.
Current OZEV home charger grants
The grant is not available simply because someone buys a home EV charger. Property, parking, vehicle, installer and equipment requirements apply.
Use the OZEV Grant Eligibility Checker as a first step, then verify eligibility against the current official guidance.
What if you park on the street?
A home charger does not automatically solve the problem of getting a charging cable safely from the property to an on-street vehicle.
The current OZEV household on-street parking grant is designed around eligible installations that include an approved cross-pavement solution, such as a charging gully, subject to the full scheme requirements.
Which home EV charger should you buy?
There is no single charger that is automatically right for every property or driver.
Start by matching the charger to the vehicle, parking arrangement, home electrical supply and charging routine.
Once those requirements are clear, product comparisons become much more useful because you can judge features against something you actually need rather than comparing long specification lists.

Home EV charger FAQs
What power home EV charger should I get?
It depends on the vehicle’s AC charging capability, your electrical supply and how quickly you need to replenish the battery. More charger power is not automatically useful if the vehicle cannot accept it.
Is a tethered or untethered EV charger better?
Neither is universally better. A tethered charger keeps the cable attached for convenience, while an untethered charger allows the cable to be removed and stored separately.
Can I charge an EV from a normal three-pin socket?
Some vehicles can use suitable portable charging equipment, but a dedicated home chargepoint is designed specifically for routine EV charging. Follow the vehicle, charging-equipment and electrical safety guidance for your installation.
Do home EV chargers have smart charging?
Covered private chargepoints sold for domestic or workplace use in Great Britain are subject to the smart chargepoint regulations, which include smart functionality requirements.
Can I get an OZEV grant for a home charger?
Certain renters, flat owners and qualifying households with on-street parking can be eligible under current schemes. Eligibility depends on the property, parking, vehicle, charger and installation.
How much is the current residential EV charger grant?
Current qualifying schemes can cover 75% of eligible purchase and installation costs up to a maximum of £500.
Does a faster wallbox always charge the car faster?
No. The vehicle’s maximum AC charging rate and the available electrical supply can limit the charging power.
Should I compare charger price or installation price?
Compare the complete installed cost. Cable routes, electrical work, groundworks and other site-specific requirements can change the final price substantially.
