Charging at home · UK guidance
Which home charger do I need, and why?
Choose a charger that works with your car, your property and the electricity tariff you want to use. Around 7kW is a common home setup, but the right choice depends on how much charge you need overnight and what your supply can support. An installer should check the property before confirming the work and price.
Check four things together
A charger can fit your car’s plug and still be a poor match for your routine. Before buying, put these four checks together:
- Your car: the exact model, its home charging limit and where its charging port sits.
- Your property: parking position, permissions, cable route and electrical supply.
- Your charger: cable length, everyday controls, support and any solar features you need.
- Your tariff: the supplier’s current car or charger compatibility list and smart-meter requirements.
Do I need the fastest home charger?
Usually the useful question is how much energy you need to replace before you next leave. A higher charger rating cannot overcome your car’s charging limit or the home’s supply limit. For example, replacing 20kWh at a steady 7kW takes about three hours before charging losses. This is an illustration, not a promised charging time. Ask the installer what output your particular setup will deliver.
An attached cable or a separate cable?
A tethered charger has its cable attached, so there is less to unpack each time. An untethered charger has a socket and needs a separate compatible cable. Think about where you park, which side of the car the socket is on and where the cable will be stored. Check you can reach comfortably without creating a trip hazard.
Will it work with a cheap charging tariff?
Check before ordering. Some smart tariffs connect to a compatible car or charger, rather than working with every combination. For example, Intelligent Octopus Go has its own eligibility checks. That is one supplier example, not a recommendation. Compare the whole household bill and check what happens if the connection or compatibility changes.
Can I use an ordinary socket?
Do not assume an existing household socket and wiring are suitable for repeated EV charging. Get a qualified electrician’s advice and follow the vehicle and charging-equipment instructions. A dedicated chargepoint is normally the practical option for regular home charging. Do not use a domestic multi-socket extension lead to reach the car.
What if I rent, live in a flat or have no driveway?
Check who owns the parking space and who must approve the work. Flats and rented homes can need landlord or managing-agent permission. If you park on the street, an approved council scheme or a dependable public charging routine may be more appropriate. A grant is not automatic.
