Electric car charging at home

What is a home chargepoint?

Typically, it’s a box installed on an outside wall of your home. Using a cable and plug, you can then connect it – and therefore your home electricity supply – directly to your car. 

How does it work?

It’s as straightforward as picking up the cable and plugging it straight into your car’s power socket. Once the connection is made, the battery will begin to charge.

All new chargepoints sold in Great Britain for private use must now be ‘smart’. Smart features typically include the ability to:

• set reminders to charge; 
• schedule your home chargepoint to switch on at certain times, for example, in off-peak times
• keep an eye on how much electricity you’re using if you’ve got a smart meter too. 

You may also find a smart, off-peak tariff  which could save you money by allowing you to charge your car at the cheapest times of the day. Discover more about smart charging and its benefits.

Are there different types of home chargepoint?

Yes. In general, home chargepoints have a power rating of 3.7kW (a low speed chargepoint) or 7.4kW (a standard chargepoint). Although faster models are available, these are often not compatible with domestic electricity supplies and can be more expensive - so are more common in commercial settings. 

A low speed chargepoint could suit your charging needs, allowing you to recharge overnight and top up during the day. Standard chargepoints charge your vehicle quicker but can cost you more.

You should also consider whether you want tethered or non-tethered cables. 

A tethered chargepoint has a built-in charging cable and space to store it. By comparison, a non-tethered chargepoint is just a socket so you’ll have to store your charging cable in the car boot or somewhere convenient at home. You should talk to your chargepoint installer to discuss your preferences.

How long does it take to charge my battery?

This depends on the size of your EV battery, charging capability of your car and the speed of your home chargepoint.

What could it cost to charge my car using a home chargepoint?

According to Energy Saving Trust, a full charge in a fully electric car can give a typical range of around 220 miles and could cost approximately £17 if charging at home. Driving a petrol or diesel car for 220 miles could cost around £45.

You could make the greatest cost savings when you charge at home and have access to an off-peak overnight electricity tariff.

If I buy a chargepoint for installation outside my home, how much might it cost?

The cost of the charger and its installation can vary according to suppliers, chargepoint features, where you live and where you’d like it on your property. 

Unless you’re a qualified electrician, you can’t install the home chargepoint yourself. 

Depending on how your home is built, there may be extra charges too. For example, if your chargepoint location is a long way from your home’s main fuse box or requires an underground cable, the extra work and wiring could add to the installation bill. 

An accredited installer approved by the Office for Zero Emission Vehicles (OZEV) should survey your property first to give you a quote before work starts.

Can I get any help with installation costs?

There may be help, depending on your circumstances.

If you’re a flat owner in the UK you may be eligible to get either £350 or 75% off the cost of buying and installing a home chargepoint – whichever is lower – through a Government grant . If you're renting a flat or a house, you may also be eligible for a similar discount. Talk to your landlord and see what can be agreed, including for installation costs.

And if you’re a landlord with property let out, you may be eligible for help too. 

If you’re not eligible for any Government help, try shopping around to see what different providers offer. It’s also worth a look at energy companies, as some are starting to offer installation deals.

Do I need to have a driveway or live in a house?

 If you live in a house you own, with a driveway or off-street parking, it could be easier to install a chargepoint. It might also be wise to check what permissions are required ahead of installation, if you live in a conservation area or in a listed building for example. Ideally, the chargepoint will be in range of your home Wi-Fi connection to be able to use its smart functions.

You might still be able to have a chargepoint if you live in a leasehold flat as long as you’ve got a dedicated parking bay. Contact your freeholder or building manager to get things moving. If a friendly neighbour has already installed a chargepoint in their parking space, why not ask them to find out what steps they took?

What if my home doesn’t have access to a driveway?

If home charging isn't an option, public chargepoints may be able to suit your charging needs or you could encourage your employer to install a chargepoint. 

If there aren't many public chargepoints available in your area or on your regular routes, you could speak to your local council - it could apply for some government funding to help with part of the cost of installing on-street chargepoints.

Is there anything else I should consider? 

If, after consideration and discussion with anyone who might need to consent such as a freeholder or landlord, you think a home charger could be right for your circumstances, make sure you further discuss any potential benefits, savings or improvements with the relevant provider.

All information is based on the most up-to-date research from Energy Saving Trust as of January 2025. Movements in the price of gas and electricity since the date of their estimates may have an impact on the estimated savings. The estimated costs and savings are included as a good start for you to understand more about the potential costs and savings. However, the estimates given could depend on a number of factors, including type of car and how old it is, its battery size and your energy tariff.
