How Much Does It Cost to Install an EV Charger?
Most UK home installations land between £800 and £1,400. Use the calculator below for a range based on your actual property.
Estimate your EV charger installation cost
Answer six quick questions and we will show you a realistic price range for your property. Nothing is sent anywhere until you choose to ask for a quote.
That is the all-in range most home installations in Didcot land in. Answer the questions above for a range tailored to your property, or read the full cost breakdown below.
This is an estimate, not a quote. It is based on typical Didcot installations and the answers you gave — it is not a priced offer and nothing here is binding. Real pricing depends on your consumer unit, earthing arrangement, cable route and DNO requirements, all of which we confirm on survey. Your written quote is fixed before any work starts.
The short answer
A standard 7kW home EV charger installation in the UK typically costs £800 to £1,400 all-in. That figure includes the charger unit itself, the labour, all cabling and protective devices, commissioning, and the electrical certification. It is the same range we quote across Didcot, Harwell, Wantage and Abingdon, and it is what the overwhelming majority of domestic installs come in at.
You will see headline prices online well below that. They are usually the charger unit on its own, or an installation price with a fixed cable allowance so short that almost nobody actually qualifies for it. The number that matters is the all-in one.
What actually moves the price
Four variables account for nearly all the difference between a £850 job and a £1,400 one.
Distance from the consumer unit. This is the single biggest factor. A charger going on the wall directly behind your consumer unit is a couple of hours of work. A charger at the far end of a 25m driveway needs a much longer run, often in heavier cable to keep voltage drop inside regulations, and sometimes a different route entirely.
The state of your consumer unit. A modern board with a spare way takes a dedicated RCBO for £60 to £120. An old fuse board, or a board with nothing free on it, needs replacing — that is £350 to £650, and it is genuinely necessary rather than an upsell. Any installer who quotes you a home charger without looking at your board is guessing.
Whether anything has to be dug. If the cable can be clipped along a wall or fence the whole way, groundwork costs nothing. If it has to cross a driveway or lawn, you are adding £200 to £900 depending on length and surface. Lifting and relaying block paving costs considerably more than cutting a trench through grass.
Which charger you choose. Less than you would think, but still £350 at the bottom to about £700 at the top for a 7kW smart unit. The premium is mostly for solar integration and tariff smarts rather than charging speed — every unit on our list charges at the same 7kW.
Use the calculator
The calculator on this page takes those four factors plus your property type and grant eligibility and gives you a range. It is an estimate, not a quote — we do not price a job properly without a survey — but it is built from real Didcot installation pricing rather than a national average, and it will get you close.
Be careful with the £350 grant
A lot of EV charger cost guides still assume everyone gets £350 off through the OZEV chargepoint grant. That has not been true since the rules changed in 2022.
Today the grant is aimed at people renting their home, flat and apartment owners with off-street parking, landlords fitting chargers at let properties, and certain commercial and multi-unit schemes. If you own and live in a house, you are almost certainly not eligible, and you should budget accordingly. The calculator reflects this honestly — see our full OZEV grant guide for the detail.
What a fair quote should include
Before you compare two quotes, check both cover the same things. A complete home charger quote should include:
- The charger unit, clearly named with the model
- All cabling, with the included run length stated in metres
- The isolator, RCBO or other protective devices
- Labour and commissioning, including app setup
- The electrical installation certificate
- DNO notification, where it is required
If a quote does not state the included cable length, that is the first question to ask. It is where the difference between a cheap headline price and a final invoice usually hides.
Running costs, for context
The installation is a one-off. Charging at home on an overnight EV tariff typically costs a fraction of public rapid charging, which is why most Didcot households we install for see the charger pay for itself inside about 18 months on fuel savings alone. If you are weighing up whether the install cost is worth it, that is the number to run against your own mileage.
Costs in Didcot specifically
We install across every kind of housing stock in the area — the older terraces near Didcot Parkway, the newer estates at Great Western Park, Ladygrove and Valley Park, and rural properties out towards Blewbury and Harwell. Newer estate properties tend to sit at the lower end of the range: modern consumer units, short runs, driveways right next to the house. Older terraces and converted properties more often need board work or a longer route, which pushes them up. Rural properties with detached garages are the ones most likely to need a separate supply run.
Whatever yours turns out to be, you get a fixed written quote before we book anything, and the price on it is the price you pay.
EV charger installation costs, line by line
Typical pricing based on what we actually charge in Didcot and the surrounding OX postcodes. These are ranges — your written quote is the fixed number.
| Item | Typical cost | What drives it |
|---|---|---|
| 7kW smart charger unit | £350 – £700 | Brand, tethered vs untethered, solar and tariff integration |
| Standard installation and certification | £450 – £700 | Labour, first 10m of cable, isolator, testing, DNO notification |
| Extra cable run beyond 10m | £90 – £550 | Distance, cable size needed to hold voltage drop, routing difficulty |
| Consumer unit work | £60 – £650 | A spare way is cheap; a full board replacement is not |
| Groundwork or trenching | £200 – £900 | Length, and whether you are lifting lawn or block paving |
| Flat or communal property premium | £150 – £400 | Communal routing, freeholder permission, longer supply runs |
| OZEV grant, if eligible | minus £350 | Flats, rentals and landlord installs only, not owner-occupied houses |

EV charger cost questions
The cost questions we get asked most often, answered straight.
How much does it cost to install an EV charger in the UK? +
A standard 7kW home EV charger installation in the UK typically costs between £800 and £1,400 all-in, covering the charger unit, labour, cabling, protective devices and electrical certification. Installations at the lower end are short cable runs into a modern consumer unit; the higher end reflects longer runs, older boards, or premium chargers. Costs above £1,400 usually mean groundwork, a consumer unit replacement, or a supply upgrade is involved.
What makes an EV charger installation more expensive? +
Four things account for almost all the variation: the distance from your consumer unit to the parking space, whether the consumer unit has spare capacity or needs replacing, whether the cable can be clipped to a wall or has to be trenched, and which charger you pick. A 30m run across a block-paved driveway into an old fuse board can easily cost double the same charger fitted 5m from a modern board.
Does the £350 OZEV grant apply to my house? +
Probably not. Since the rules changed in 2022 the OZEV EV chargepoint grant no longer covers owner-occupied single houses. It is currently aimed at people renting their home, flat and apartment owners with off-street parking, landlords installing at let properties, and certain commercial and multi-unit schemes. Any installer advertising £350 off to every homeowner is working from out-of-date rules.
How much does it cost to upgrade a consumer unit for an EV charger? +
Adding a dedicated RCBO to a modern board that has a spare way typically costs £60 to £120 on top of the installation. A full consumer unit replacement, which is what an old fuse board or a board with no spare capacity needs, typically runs £350 to £650. We always quote consumer unit work as a separate, clearly labelled line rather than burying it in the installation price.
Is a 22kW charger more expensive to install than a 7kW one? +
Considerably, and for most homes it is not possible at all. A 22kW charger needs a three-phase supply, which the overwhelming majority of UK homes do not have. Bringing three-phase in from the street is a DNO job that typically runs into several thousand pounds. Almost every domestic installation in Didcot is a 7kW single-phase unit, which adds well over 100 miles of range overnight.
Are there hidden costs with EV charger installation? +
There should not be. A proper quote is issued after a survey and includes the unit, labour, all cabling and protective devices, commissioning, certification and DNO notification. The things that catch people out on cheap headline prices are cable runs beyond a fixed allowance, consumer unit work, and making good after trenching. We itemise all three up front, and our written quote is fixed before we book the job.
