The short answer
Smart Energie's published price for a 7kW smart home charger is £975 to £1,400, depending mainly on the cable run and whether load balancing is needed. If you rent or own a flat and have private off-street parking, the government's EV chargepoint grant pays 75% of the cost of buying and installing a socket, up to £500; people who own a house cannot claim it. Chargers are not on HMRC's zero-rate list for energy-saving materials, so VAT is normally charged at the standard 20%. At the October to December 2026 price cap, 7,000 miles of home charging costs about £614 on our stated assumptions, or about £373 at an assumed 16p overnight rate.
What does a home EV charger cost to install?
Most home chargers in the UK are 7kW units on a normal single-phase supply. That is roughly 7 miles of range for every 20 minutes plugged in, on the Energy Saving Trust's rule of thumb.
| What | Price |
|---|---|
| 7kW smart charge point, installed | £975 to £1,400, depending on cabling and load balancing |
| Solar panels, battery and EV charger together | From £10,500 |
Our solar, battery and EV charger page sets out what each package covers.
What pushes the price up?
- Cable run. A charger on the wall beside the consumer unit is the simplest job. A long run to a detached garage or the far side of a driveway needs heavier cable, fixings, and sometimes digging and making good.
- Consumer unit. A charger needs its own protected circuit. If your consumer unit has no spare way, or is old, it may need upgrading first.
- Earthing. Many UK homes have a PME (protective multiple earthing) supply. Because an outdoor car is a conductive object people touch, BS 7671 regulation 722.411.4.1 sets extra protection against a broken supply neutral. The IET describes two main answers: a separate earth rod for the charger, or a device that detects the fault and disconnects. Which one suits your home is decided at survey.
- Load balancing. A 7kW charger draws about 32 amps. If your main fuse is small, or you also run a heat pump, electric shower or oven, the charger may need a sensor that slows charging when the house is busy.
- Network operator approval. If the charger takes your home's maximum demand above 60 amps per phase, the installer must apply before fitting it (see below), and a supply upgrade adds time and possibly cost.
Is there still a grant for a home charger?
Yes, but only for some households. The electric vehicle chargepoint grant for renters and flat owners, run by the Office for Zero Emission Vehicles (OZEV), pays 75% of the cost of buying and installing a charger socket, up to a maximum of £500. Landlords apply through a separate route.
| You can apply if | You cannot apply if |
|---|---|
| You live in a flat you own or rent, or rent a whole property, including shared ownership | You live in a house you own, unless it is converted into flats and you live in one of them |
| You have private, clearly defined off-street parking you can use at all times, with the legal right to it | You are a lodger where the landlord or homeowner lives |
| You own, lease or use an eligible EV for work, or have one on order | You are moving or planning to move |
| You use an OZEV-authorised installer and an approved charger model | A charger is required by law, for example because the home is a new build, or you have claimed before |
The order matters. Your installer gives you a dated quote, you gather written permission from your landlord, freeholder or managing agent, and you apply online. The charger must not be installed before OZEV confirms you are eligible. The installer then claims the grant and it is paid to them, so it comes off your bill.
What must a home charger legally be able to do?
Under the Electric Vehicles (Smart Charge Points) Regulations 2021, charge points sold for home or workplace use in Great Britain since 30 June 2022 must be smart. The main requirements are:
- the ability to send and receive information and respond to signals to change when and how fast the car charges
- keeping smart functions if you switch electricity supplier, and still charging if the internet connection drops
- pre-set off-peak default charging hours, which you can accept, remove or change on first use and later
- a randomised delay function, so thousands of chargers do not all start at once
- a way to measure electricity use and charging time that you can see, and cyber security in line with the ETSI EN 303 645 standard (since 30 December 2022)
Does your electricity network operator need to know?
Yes, every time. The standard form produced by the Energy Networks Association for EV chargers and heat pumps sets out two routes:
- Connect and notify: if your home's maximum demand, including the new charger, stays at or below 60 amps per phase, the installer can fit it and notify the network operator within 28 days.
- Apply first: above 60 amps (and up to 100 amps) the installer applies before installing, and the network operator should confirm within 10 working days whether it can be connected.
What about new-build homes?
In England, Part S of the Building Regulations has applied since 15 June 2022. A new residential building with associated parking must give its parking spaces access to a charge point, and Approved Document S says those charge points should have a minimum nominal rated output of 7kW. There is a cost cap: if the grid connection for each charge point would cost more than £3,600, cable routes can be installed instead. Part S also applies to buildings becoming homes through a material change of use and to major renovations. Because a charger is required by law in these cases, the OZEV grant is not available for them.
What VAT do you pay on a charger and on charging?
The zero rate of VAT on energy-saving materials, in HMRC's VAT Notice 708/6, runs until 31 March 2027 and covers items such as solar panels, heat pumps, insulation and batteries. EV chargers are not on that list, so the zero rate does not apply. Unless another relief applies, installing a home charger is charged at the standard VAT rate of 20%.
How much does it cost to charge an EV at home?
Here is an illustration with the assumptions stated, so you can swap in your own mileage and tariff:
- Mileage: 7,000 miles a year, an illustrative figure. Use your own.
- Efficiency: 3 miles per kWh, which is what the Energy Saving Trust's rule of thumb implies (7kW for 20 minutes is about 2.33 kWh for 7 miles). Your car's real figure may be higher or lower, and some energy is lost while charging.
- Standard rate: 26.32p per kWh, the Ofgem price cap for Direct Debit customers, 1 October to 31 December 2026, with no VAT.
- Overnight rate: 16p per kWh, the Economy 7 style off-peak rate the Energy Saving Trust modelled in July 2026. It is an illustration, not a real offer. Tariffs designed for EV charging may be lower, so compare what is available to you.
| Rate | Cost per mile | Cost per year |
|---|---|---|
| 26.32p per kWh (price cap) | About 8.8p | About £614 |
| 16p per kWh (assumed overnight rate) | About 5.3p | About £373 |
At 7kW, 2,333 kWh is about 333 hours of charging a year, or around 6 and a half hours a week, which fits comfortably into overnight off-peak windows. The smart functions the law requires are what let the charger work to those windows automatically. Pairing charging with solar panels or a battery can shift more of it onto your own electricity; our guide to whether a battery is worth it explains the trade-offs, and what a home battery costs covers prices.

Common questions
How much does it cost to install a 7kW EV charger at home?
Smart Energie's published range is £975 to £1,400 for a 7kW smart charge point, depending on cabling and load balancing. A long cable run, a consumer unit upgrade or earthing work can push a quote higher.
Can homeowners still get an EV charger grant?
Not if you own and live in a house. The OZEV grant is for people who own or rent a flat, or rent a whole property, and have private off-street parking. It pays 75% of the cost, up to £500.
Is there 0% VAT on EV chargers?
No. EV chargers are not on HMRC's list of energy-saving materials in VAT Notice 708/6, so unless another relief applies the installation carries the standard rate of 20%.
Do I need to tell my network operator about a home charger?
Yes, and your installer normally does it. If your home's maximum demand stays at or below 60 amps per phase they notify within 28 days of fitting; above that they must apply first.
How long does a 7kW charger take to charge a car?
The Energy Saving Trust's rule of thumb is roughly 7 miles of range for every 20 minutes on a 7kW charger, or about 21 miles an hour, so an 8-hour overnight session adds roughly 160 to 170 miles of range.
