Frequently asked questions
How much does it cost to install a home EV charger in the UK?
A typical 7 kW home charger costs around £800 for the unit and £500-800 for installation, giving a total of £1,300-1,600. The OZEV grant reduces this by £350. Costs vary depending on your property type and distance from the consumer unit.
What is the OZEV grant for home chargers?
The Electric Vehicle Homecharge Scheme (EVHS) provides up to £350 towards installing a home charger. You need off-street parking and must use an OZEV-approved installer. The grant is available to homeowners, tenants, and landlords across the UK.
Do I need a 7 kW charger or will 3.6 kW do?
A 7 kW charger is the most popular choice and adds around 30 miles of range per hour. A 3.6 kW charger is cheaper but adds only 15 miles per hour, meaning a full charge takes roughly twice as long. For most people, 7 kW overnight charging is more than sufficient.
Can I install a 22 kW charger at home?
A 22 kW charger requires a three-phase electricity supply, which most UK homes do not have. Upgrading to three-phase costs £1,000-3,000 from your DNO and is usually only worthwhile for commercial premises. For most homeowners, 7 kW is the best option.
Can I charge an EV in a flat?
It is possible but more complex. You need permission from the freeholder or management company, and installation costs are higher due to longer cable runs. The OZEV grant covers flats too. Some councils and housing associations are installing communal chargers.
