How much does it cost to install an EV charger at home in the UK (2026)
Grants and costs. 5 minute read
Why two quotes for the same charger can be hundreds of pounds apart, how VAT and the £500 grant apply, and what a charge at home costs once the charger is on the wall.
£500 to £1,200 is the range Which? gave in February 2026 for buying and fitting a home EV charger, and it named around £900 for a 7kW unit, the power it calls a good choice for most homes. Check what each price includes: the charger, the cable from your fuse board, protection for the new circuit, labour, the certificates and the network operator notification.
Which? puts most of the price difference between chargers down to their power. Between two quotes for the same charger, the difference comes from the house.
Why two quotes for the same charger differ
The distance from the fuse board to the parking spot. A charger on the outside wall behind the consumer unit might need a few metres of cable. A detached garage across a drive can need trenching or cable clipped along a fence line, and every extra metre is cable and time. The Spark Up quote form asks for this distance for that reason.
The state of the consumer unit. A board with no spare way may need a separate small unit for the charger, or a replacement, which is a job in its own right. Age alone is not the test: Electrical Safety First says rewirable fuses are not on their own a reason to replace one. Our guide to fuse boards, looped supplies and earthing covers what the installer looks for.
Earthing. A house with a PME earth needs extra protection at an outdoor charger. Some chargers have it built in; otherwise a separate device or an earth electrode is added, and the quote rises with it.
The supply into the house. If the property's maximum demand with a charger added is too high, the installer either fits load management or the network operator has to look at the supply. Which? says that if your supply cannot cope, "your energy network operator will need to upgrade your supply".
The charger itself. Which? says the price difference between models is "largely down to the amount of power it can supply", and a longer tethered cable adds to it.
Send two photos with any request: the fuse board with its cover closed and the spot where the car parks. They let an installer price a simple job before visiting, and a quote built on them is less likely to change on the day.
VAT on the quote
HMRC's list of energy saving materials that get 0% VAT until March 2027 includes solar panels and batteries but not EV chargers. A charger added to an existing home is therefore not covered by that relief, so read whether a quote is shown with or without VAT before comparing it with another. New builds are different: charging points are now on the list of zero rated items in VAT Notice 708, for qualifying new build work.
What the grant takes off
If you own your house and park on your own drive, there is no grant. Flat owners, renters, landlords and some households with street parking can claim 75% of the cost, up to £500, until 31 March 2027. On a £900 job, 75% is £675, so the grant pays the £500 cap and £400 is left to pay. The details, including who is excluded, are in our EV charger grant guide.
What a charge costs once it is fitted
The figures below are an example: adding 40kWh, two thirds of a 60kWh battery.
| How you charge | Price per kWh | 40kWh top up |
|---|---|---|
| Home, at the Ofgem cap rate for late 2026 | 26.32p | £10.53 |
| Home, on an EV tariff at the low rate Which? found | 7p | £2.80 |
| Ultra rapid public charger, Which?'s typical minimum | 79p | £31.60 |
The cap rate is the average Direct Debit unit rate from Ofgem for 1 October to 31 December 2026, a quarter with no VAT on electricity. The 7p and 79p rates come from Which?'s cost of charging guide, checked in April 2026. Your own unit rate depends on your supplier, your region and your tariff.
On those figures, the gap between home on an EV tariff and an ultra rapid charger is £28.80 per 40kWh. At one such top up a week, a £900 charger would take about 31 weeks to make back against ultra rapid charging, and longer against cheaper public posts or a standard home tariff. The arithmetic only holds if the car sits on your drive overnight on a cheap rate, which is what our guide to smart chargers and off peak tariffs is about.
The 3 pin plug question
A car can charge from an ordinary socket through a 3 pin charging cable, which needs nothing installed. Zapmap puts it at about 2.3kW and says a full charge of a large battery can take over 24 hours. It also advises against relying on it, because it is slow and the socket can overheat on long sessions. For a car that covers a few miles a day it can be enough while a charger is arranged, but have an electrician look at the socket first.
Where a cheap quote can cost more
A fixed price that does not mention the earthing arrangement, a survey of the fuse board or notifying the network operator either includes all three or has left them for later. Ask which. When you request quotes on Spark Up, the installers near you who fit home EV chargers all see the same answers and photos, so their prices are built on the same information.
