Quick Answer
A 7kW home EV charger installed in the UK costs £800–£1,500 in 2026. Eligible homeowners can reduce this by up to £350 through the OZEV EV Chargepoint Grant. The work must be carried out by an approved OZEV installer.
Electric vehicle ownership in the UK has grown dramatically, and home charging is now the most convenient and cost-effective way to keep your car topped up. But with dozens of charger models, government grant schemes, and varying installation costs, choosing the right setup is confusing. This 2026 guide cuts through the complexity and tells you exactly what a home EV charger costs, what grant money is available, and what the installation involves.
In this guide
Charger Types: 3.6kW vs 7kW
Home EV chargers come in two main power ratings for domestic use:
| Type | Power | Charge Rate | Typical Install Cost | Best For |
|---|---|---|---|---|
| 3-pin plug (EVSE cable) | 2.3kW | ~8–10 miles/hour | No installation needed | Occasional use, low mileage only |
| 3.6kW (slow) | 3.6kW | ~12–15 miles/hour | £600–£1,000 | Older homes with single-phase limitations |
| 7kW (fast, standard) | 7kW | ~25–30 miles/hour | £800–£1,500 | Most modern homes — recommended |
| 22kW (3-phase) | 22kW | ~75 miles/hour | £1,500–£2,500 | Homes with 3-phase supply — rare |
The vast majority of UK homeowners install a 7kW charger — it charges most EVs overnight from empty to full and works on a standard single-phase domestic supply. Unless you have specific high-mileage needs and a 3-phase supply already, 7kW is the right choice.
Popular UK charger brands include Ohme, Pod Point, Zappi (myenergi), Andersen, and EO Charging. Smart chargers — which can schedule charging to off-peak tariff times and communicate with the grid — are now standard and worth having in 2026.
OZEV EV Chargepoint Grant
The Office for Zero Emission Vehicles (OZEV) offers grants to help reduce the cost of home EV charger installation. In 2026, the EV Chargepoint Grant provides up to £350 off the cost of purchasing and installing a charger.
Eligibility requirements:
- You must own or have ordered an eligible plug-in electric vehicle (the list includes most modern EVs)
- You must own or have sole use of a private parking space (driveway or garage)
- The property must have a dedicated off-street parking space
- The charger must be installed by an OZEV-approved installer
- The charger itself must appear on the approved product list
The grant is applied automatically by the installer at the point of purchase — you do not claim it separately. However, you must use an OZEV-approved installer for the grant to apply. Always confirm grant eligibility and scheme details directly with your installer, as grant terms can be updated by OZEV.
Even without the grant, the economics of home charging make sense — a typical 7kW installation pays for itself within 2–3 years compared to public rapid charging costs.
What the Installation Involves
A 7kW EV charger requires a dedicated 32A circuit from your consumer unit. Here is what the installation process involves:
- Consumer unit assessment — The installer checks whether your board has a spare way and adequate earthing. If not, an upgrade may be required. See our consumer unit replacement cost guide for what this involves.
- Cable run — A 6mm² twin-and-earth cable (or armoured cable if running externally) is run from the consumer unit to the charger location
- Earthing and PME assessment — Most UK homes have a PME (Protective Multiple Earthing) supply. EV chargers require additional earthing measures under BS 7671 Amendment 1 (2020). Your installer will add a separate earth rod if needed.
- Charger mounting and wiring — The charge point unit is fixed to the wall and connected
- Testing and commissioning — The circuit is tested and the charger is set up with the associated app and any time-of-use tariff scheduling
The earthing requirement is the element most homeowners do not expect. Almost all homes with a PME supply need an additional earth electrode for the EV charger circuit. This is non-negotiable under current regulations and is the reason some "cheap" quotes do not include it — always check.
Approved Installers
EV charger installation is notifiable work under Part P of the Building Regulations. It must be carried out by a registered electrician. For the OZEV grant, the installer must additionally be OZEV-approved. Most NICEIC or NAPIT registered electricians who specialise in EV charging will be OZEV-approved — always confirm before booking.

Running Costs: How Much Does It Cost to Charge at Home?
Charging at home is significantly cheaper than public rapid charging. Using a smart charger to charge overnight on an off-peak tariff (such as Octopus Go or OVO Beyond), typical costs in 2026 are:
- Standard tariff (~£0.27/kWh): ~£14–£19 for a full charge of a 60kWh battery
- Off-peak EV tariff (~£0.10–£0.12/kWh): ~£6–£8 for the same charge
- Public rapid charger (£0.70–£0.90/kWh): £42–£54 for the same charge
For most EV drivers, an off-peak home charging tariff cuts fuel costs to a fraction of public charging — and well below petrol or diesel equivalents. The investment in a home charger pays for itself quickly.
Frequently Asked Questions
Can I charge an EV from a standard 3-pin socket?+
Yes, but it is not recommended as a permanent solution. A 3-pin socket provides around 2.3kW — roughly 10 miles of range per hour. Prolonged use of a domestic socket for EV charging can overheat the socket and wiring. A dedicated charger is safer, faster, and more cost-effective.
Does my consumer unit need upgrading for an EV charger?+
Possibly. An EV charger requires a dedicated 32A circuit. If your consumer unit has no spare ways or is old and inadequately protected, an upgrade may be needed. Many older properties needing consumer unit upgrades and EV charger installation benefit from having both done at the same time to save on call-out costs.
How long does EV charger installation take?+
A standard home EV charger installation takes half a day to a full day — typically 4–6 hours. More complex jobs with long cable runs, earthing work, or consumer unit upgrades take longer.
Do I need planning permission for a home EV charger?+
No — in most cases, home EV charger installation is permitted development and does not require planning permission. Listed buildings and properties in conservation areas may have restrictions. Always check with your local authority if you are unsure.
Can I install a second EV charger for two cars?+
Yes. Many households now install two chargers — or use a dual-socket charger. Load management features on smart chargers can share the available supply between two vehicles, so you do not necessarily need to upgrade your consumer unit for two chargers. Get a quote that includes a load management assessment.
What happens to my EV charger if I sell my house?+
The charger is a fixed installation — it stays with the house, like any other fixed electrical fitting. It adds value, particularly as EV ownership grows. Make sure you have the Part P certificate to pass to the buyers.
