EV Charger Installation Cost in the UK, and What Changes the Price

Most UK homes pay between about £500 and £1,200 to buy and install a home EV charger, according to Which?, and a standard 7 kW wallbox typically comes in at around £900 fitted. That figure assumes a straightforward job: the charger close to the consumer unit, a short cable run, and a supply and fuse board that can take the extra load. Where any of those is missing, the price climbs, sometimes by more than the charger itself.


What does a standard EV charger installation include?

A standard installation is the baseline most fixed-price quotes are built on. It usually covers a 7 kW smart charger mounted on an outside wall, a new dedicated circuit from the consumer unit, a short cable run (each installer sets its own included length), the protective devices for that circuit, testing, and the paperwork.

That paperwork matters. A charger needs its own new circuit, and installing a new circuit is notifiable work under Part P of the Building Regulations in England. A registered electrician who can self-certify the work under Part P will give you an Electrical Installation Certificate and arrange the Building Regulations compliance certificate. Your installer should also register the charger with your local network operator (DNO), which the Energy Saving Trust notes is usually done for you.


For our own EV charger installation, we survey first, because the survey is where the difference between a standard and a non-standard job shows up.


What makes an EV charger installation cost more?

These are the items that turn a standard install into a bigger one, roughly in the order we find them on real surveys.


A long or awkward cable run

The further the charger is from the consumer unit, the more cable you pay for, and the heavier it gets. A 7 kW charger draws 32 A for hours at a time, so the cable has to be sized for that load and for the voltage drop over the distance. A detached garage, a drive on the far side of the house, or a route that has to go through several walls or under a path all add material and labour. Burying cable across a garden or drive means digging a trench and reinstating the surface, which is often the single biggest extra.


A consumer unit that can't take another circuit

The charger's circuit needs a spare way in the board and the right type of protection. Many older boards have no space, use rewireable fuses, or have protection that isn't suitable for an EV circuit. The options are a small separate enclosure for the charger circuit or a full consumer unit upgrade, which is a separate job with its own price and is also notifiable.


Earthing: PME and open-PEN protection

Most UK homes have a PME earthing arrangement, where the earth is provided through the supply's combined neutral and earth conductor. BS 7671 restricts using a PME earth for a charger used with a car parked outdoors, because if that combined conductor breaks upstream, the car's metal body can rise to a dangerous voltage. The IET notes that many popular chargers now include open-PEN protection that disconnects the car when the supply voltage goes outside set limits. If yours doesn't, or the installation needs it for another reason, the electrician may fit a separate open-PEN device or an earth rod so the charger is earthed independently. Either adds cost.


RCD protection for DC faults

Each charger must be protected by its own 30 mA RCD, and that protection has to cope with DC fault current. A charger with built-in 6 mA DC detection can use a Type A RCD. One without needs a Type B RCD, which costs noticeably more. Checking this before you buy the charger avoids paying for the more expensive device.


A supply that needs upgrading

Your installer should look at the maximum demand of the house with the charger added. If the main fuse or the supply cable can't carry the extra load, the network operator may need to upgrade the supply before the charger goes live. Some chargers can avoid this with load management, which turns the charging rate down when the house is busy. Supply upgrades are the network operator's work, priced and scheduled by them.


How much more is a 3.6 kW or 22 kW charger?

Which? notes that 3.6 kW chargers tend to be the cheapest and 22 kW chargers the most expensive. A 22 kW charger only works at full speed on a three-phase supply, which most UK homes don't have, and on a car that accepts 22 kW on AC. For nearly everyone, 7 kW is the practical ceiling on a single-phase home supply, and that is where most of the market sits.


What a fixed-price online quote leaves out

Online packages are real prices for a real job, but only the standard job. Read what they exclude. Common exclusions are:


  • cable runs beyond the included length

  • groundworks, trenching and making good

  • a new or additional consumer unit

  • an earth rod or separate open-PEN device

  • work to a detached garage or outbuilding

  • any supply upgrade by the network operator


If your house needs any of these, the final bill will be higher than the headline. A price given after someone has looked at your board, your earthing and your parking is the one to budget on.


Can you still get a grant?

If you own a house with its own driveway, no: owner-occupiers of houses with off-street parking are not among the eligible groups. Since 1 April 2026 the government's chargepoint grants have been open to people who live in flats or rent, households with on-street parking, residential landlords, workplaces and state-funded education institutions, and the charger must not be installed until you have been told you are eligible. Rules change, so check the current position on gov.uk before you commit rather than relying on a figure from an installer's website.


How to compare EV charger quotes

Put quotes side by side on the same points, not the same total:


  1. Is the charger the same power and the same model, tethered or untethered?

  2. What cable length is included, and what is the rate beyond it?

  3. Has the installer checked the consumer unit, and is any upgrade priced?

  4. How is open-PEN protection handled: built into the charger, a separate device, or an earth rod?

  5. What RCD type is included?

  6. Does the price include notifying the network operator and the Part P certificate?


A quote that answers all six is easier to trust than a cheaper one that answers two.


From our base in Shifnal we survey and fit home chargers across Wolverhampton, Telford and the West Midlands, and we price the whole job, extras included, after looking at your supply. If you want a figure for your own driveway, get in touch and we'll arrange a visit.


EV charger cost questions, answered

Is it cheaper to charge from a normal plug instead?

A 3-pin socket costs nothing to install, but at around 2.4 kW it is slow, and a standard socket and circuit weren't designed for hours of heavy load. It is fine as an occasional backup if the socket and wiring are in good condition. For daily charging, a dedicated charger is the safer choice.


How long does an EV charger installation take?

A standard installation is often done in a day. Groundworks, a board change or waiting for the network operator stretch that out.


Does the charger brand change the installation cost?

Only through what the charger has built in. A model with open-PEN protection and 6 mA DC detection saves on extra devices, which is why we rate those two features above app design when choosing the best home EV charger. As more homes add cars and heat pumps to the same supply, as we cover in UK home electrical trends, the survey matters more than the badge on the box.
