Electric car charger installation cost

A home charger is a near-essential if you have off-street parking and are buying an EV; we explain the costs involved

For those lucky enough to have a driveway, garage or other form of off-street parking, getting a home charger – sometimes called a wallbox – installed should be one of the first things you investigate as you begin looking at making the switch to electric motoring.

The UK government used to issue grants of up to £350 to help towards the cost of getting a home EV charger installed, but this grant ended in March 2022, and now only landlords or people who live in flats can apply for a grant.

That means understanding the prices involved in getting a wallbox installed has never been more important, and this guide breaks down some of the costs you can expect to encounter.

Cost of installing an electric car charger at home

The most common type of home charger currently available is the 7.2  kiloWatt (kW) AC model. Slower 3.6kW chargers are available and are marginally cheaper, but aren’t really worth it, as your standard three-pin home wall plug already offers 2.3kW charging speeds.  

Three-pin plugs not only take a very long time (think 24 hours or more) to fully charge an EV, but they’re not really designed to continually handle the high demand an EV requires when charging, so are best only used in an emergency.

The majority of companies bundle the charger and installation cost into one, with the price you see advertised typically being the price you pay – although complex installations – such as ones where the main fuseboard is a long way away from where the charger will be installed – can cost more.

Also bear in mind that homes with older electrics may need to have their circuitry upgraded in order to have a home wallbox installed. The chargebox company will be able to assess if this is the case with your home when they provide you with a quote for the job. 

Faster 22kW chargers are available, but they require three-phase power supplies which are UK households do not have by default. It is possible to have your power supply upgraded, but this can be an expensive and involved business, with prices range from £3,000, and exceeding well over £15,000 depending on the nature and location of your home and its electricity supply. 

Chargers have become pretty advanced in recent years,  with wi-fi connectivity and dedicated smartphone apps now almost par for the course. Their prices are also slowly coming down, and while there may no longer be a Government grant available for most people, wallboxes can be had from around £600 or so. Units with their own LCD display screen rather than relying solely on an app can be more expensive, as can those which can be linked to and liaise with solar panels (fi you have these). Budget £900 to £1,100 for a more sophisticated charger. 

How is an electric car charger installed?

An electric car charger is installed on an exterior wall, and will be close to where you park, and ideally close to the point where your home’s main electrical feed enters the property.

The installation process starts with a home survey to assess your particular setup, and this is usually a no-cost service. The charger company will also tell you if any upgrades are required to your home electricity supply; if they are, this must be done before the charger can be installed, and it is often necessary to involved the electricity infrastructure company for upgrades, adding time to the process. 

The next step is to have the charger installed in a suitable location, connecting the wiring to your fuse box and installing an isolator switch. The system is then tested to ensure that all is working as it should.

Most wallbox companies offer an installation service, and it’s best to let them take care of it; this way you have one point of contact in case anything goes wrong. The installation charge includes all the wiring and cabling that is required for the job, and it should take around 2-3 hours for most installs.

What do you need to install an electric car charger?

You need to have a few things in place before you can have a home charger installed:

  • Suitable off-street parking
  • Suitable home electricity supply
  • Parking spot should be within 10 metres of the electricity meter
  • Permission from the landlord if you rent the property

Are there any government grants?

The Electric Vehicle Homecharge Scheme (EVHS) was a programme offered by the government which covered 75% of the purchase and installation cost of a home charging point up to a maximum of £350. This scheme was primarily focused on homeowners.

The EVHS was replaced by the EV chargepoint grant on 1 April 2022. The new grant also provides funding of up to 75% (to a maximum of £350) towards the cost of installing chargepoints at domestic properties, but, this grant focuses on tenants, flat-owner occupiers and landlords, rather than homeowners.

How much does it cost to charge an electric car at home?

Home charging can save you a significant amount compared to using public chargers. Public charging prices vary, with some including connection and usage fees on top of the already inflated electricity charges. 

Vehicle Battery Size Range on 100% charge Home charging from 0% to 100% Public charging from 0% to 100%
Tesla Model 3 60kWh 305 miles £15 £33

These calculations £0.25/kWh for domestic charging and £0.55/kWh for public chargers, and we should also highlight a 0-100% charge will only every be theoretical for most people, as totally running out of charge is undesirable and unlikely from a practical point of view, while running batteries down to totally empty is not good for their longevity. Official EV ranges tend to be more optimistic than their real-world ranges, too. 

Nonetheless, if we assume for the sake of argument that you will cover 8,000 miles in a year, that’s roughly 26 charges based on the above. Those would cost you £390 if using a home charger, or £858 using public charging. We should point out, though, that at the time of writing energy prices have been anything but stable of late.
