How can I get an EV charging wallbox fitted at home?

If you own an electric car, you will want to charge it at home if possible. It’s just so convenient – and usually the cheapest option, too.

In fact, unless you’re one of the small number of (pre-2018) Tesla Model S or Model X owners who qualifies for free refuelling at Supercharger stations, the only reason you might not charge your EV at home is that you can’t – i.e. you don’t have an off-street parking space.

The convenience of home charging means you don’t need to interrupt your journey to stop at an overpriced motorway services. At public chargers, you may also have to wait for other EVs to leave before you can plug in, which makes the process take longer.

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 ‘granny cable’ to do this, and there’s no set-up fee.

However, this isn’t a practical long-term solution as charging takes so long – several days, potentially. 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 can 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. The fitting 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 vehicle.

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 people 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. And as a 7kW device typically costs less than £100 more than a 3.6kW alternative, 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 carry in your car’s boot into the socket and the other end into the vehicle itself.

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 an installation can also be done online.

Under the government’s EV chargepoint grant, people who live in flats or rented properties can claim back 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 you have a private, off-street parking space outside your property.

Here are some example costs from Pod Point, one of the major players in the supply of domestic and commercial electric car chargers. Note: the £350 grant has not been deducted from these prices.

Power               Universal            Tethered          Speed (up to)

3.6kW                £798                   £849                 12 miles per hour

7kW                   £999                   £1,049             22 miles per hour

22kW                 £1,749                £1,799              35 miles per hour
