If you own an electric car, you will want to charge it at home. It’s simply so convenient – and usually the cheapest option, too.
In fact, the only reasons you might choose not to charge at home are that you don’t have off-street parking, or are a Tesla owner who qualifies for free refuelling at Supercharger stations.
Other possibilities exist to get your electricity free of charge, but the convenience of home charging usually wins out. There’s a risk of arriving at a free charger, only to find it occupied by another EV.
Setting up a home EV charger
You can plug your electric car into a standard three-pin UK plug socket. Electric cars come with the cable to do this, and there’s no set-up fee.
The major downside is it takes so long to charge. What you need is confidence that an overnight charge, using cheaper off-peak electricity, will do the job. As the off-peak period lasts around eight hours, that really means a bespoke home charging point.
There are dozens of companies in the UK that install home charging points. They do this by tapping into your domestic electrical circuit, then running new cables to a wallbox mounted outside your house. This can usually be done within a single day.
Types of home charging points

Most new electric cars use Type 2 connectors. You don’t need to worry about choosing the wrong connector, though – your installer will select the correct type for your car.
Then you need to choose the power rating: 3.6kW, 7kW or 22kW. The higher the power, the quicker the charge. However, 22kW domestic chargers only work if you have what’s called a three-phase electrical supply to your home. These are rare in the UK, so few will have that option.
A 7kW wallbox charges at twice the rate of a 3.6kW device, and three times the rate of a standard plug socket. As a 7kW device costs less than £100 more, it’s the obvious choice.
You then need to choose between a universal charger and a tethered one. The universal charger only has a socket outlet. You plug the cable you keep in your car’s boot into the socket and the other end into the car.
More convenient is the tethered type, which has a five-metre cable attached to the wallbox. Simply uncoil it and plug it into your car.
Costs of a home EV charging point
You can find the full list of approved suppliers of home charging points by visiting the government website. Booking a fitting can also be done online.
Under the government’s Electric Vehicle Homecharge Scheme, a grant offers up to 75 percent of the cost of a fitted home charging point – up to a maximum of £350. You only qualify if your car is on the approved list and the fitting time is less than four months from delivery.
Here are some example costs from Pod Point, one of the major players in the supply of domestic and commercial electric car chargers. The £350 grant has been deducted.
Power Universal Tethered Speed (up to)
3.6kW £449 £499 15 miles per hour
7kW £549 £599 30 miles per hour
23kW £1,199 £1,249 90 miles per hour
