Why install a home EV charger?
Installing a home EV charger is one of the most convenient upgrades for electric vehicle owners. It provides reliable, cheaper overnight charging compared to public chargers and workplace charging. With the government's OZEV grant scheme and qualified installers, it's increasingly affordable. This guide covers everything UK homeowners need to know: costs, grants, installation requirements, and how to find a certified installer.
Types of EV chargers for home installation
7kW wallbox (most common)
The standard home EV charger. A 7kW wallbox typically charges a 60kWh battery (like a Tesla Model 3) to 100% in 7–8 hours. This is ideal for overnight charging. It requires a single-phase electricity supply (standard in most UK homes) and fits most garages, driveways, or external walls.
11kW wallbox (faster, three-phase)
Three-phase chargers deliver 11kW and charge the same vehicle in 4–5 hours. However, you need a three-phase electricity supply, which is less common in residential properties. Installation costs more due to potential rewiring needs. Best for those with high mileage or needing faster top-ups.
Granny chargers (slow, 3kW)
The cheapest option (£500–800), a granny charger plugs into a standard household socket. It's slow (20+ hours for a full charge) but requires no installation work. Useful as a backup but not practical for daily use in most homes.
Smart chargers
Integrated with your home energy system, smart chargers optimise charging for renewable energy usage or off-peak electricity rates. They typically cost more (£1,000–2,500 installed) but offer long-term savings and grid stability benefits.
EV charger installation costs in the UK (2026)
Standard 7kW wallbox installation
Total cost: £800–£1,500
- Charger unit: £400–600
- Installation labour: £300–700 (varies by location and existing electrics)
- Cable and connections: Included in most quotes
- OZEV grant (if eligible): -£350 (reduces cost to £450–£1,150)
Cost factors
- Location: Distance from your consumer unit affects labour costs
- Existing electrics: If your circuit needs upgrading or extending, costs increase (£200–400)
- Ground type: Running cables underground costs more than wall-mounted cables
- DNO requirement: Usually free but causes a 2–7 day delay
- Additional works: RCD protection, weatherproofing, or structural work adds cost
11kW three-phase charger
Cost: £1,500–£3,500+ — significantly higher due to three-phase supply installation requirements.
Government grants and subsidies
OZEV Home Charger Grant
The government provides up to £350 towards installation costs. This is the primary financial incentive for UK homeowners:
- Grant amount: Up to £350
- Coverage: Goes towards charger unit and installation labour
- Typical result: Reduces your out-of-pocket cost to £450–£1,150
Eligibility for the OZEV grant
- Your property must be in the UK (England, Scotland, Wales, Northern Ireland)
- You own the property (not renting)
- You have off-street parking (driveway, garage, parking space)
- Your property has never received the grant before (one charger per property)
- You own an electric vehicle registered in the last two years (in most cases)
- Installer must be OZEV-approved
How to apply for the OZEV grant
- Find an OZEV-approved installer through NearbyTraders or official government databases
- Obtain a written quote from the approved installer
- The installer applies for the grant on your behalf (most do this automatically)
- Grant is deducted from your invoice — you only pay the balance
- Installation proceeds subject to DNO notification (if required)
DNO notification and grid requirements
What is DNO notification?
DNO (Distribution Network Operator) is the company managing your local electricity grid. For chargers over 5.8kW, they require notification to ensure your local grid has capacity. This is a standard procedure, not a barrier to installation.
Do you need DNO notification?
Most 7kW home chargers require it. Your installer checks automatically using your postcode and electricity meter data. If required, they submit your information (free of charge). The process takes 2–7 days.
Does DNO notification delay installation?
Yes, typically by a few days. Rarely, the DNO may require an upgrade to your connection (cost: £500–2,000+), but this is uncommon in urban and suburban areas. Your installer will advise if costs apply.
Installation requirements and safety standards
Electrical standard: BS 7909 and IEC 62196
All EV chargers must meet UK electrical safety standards. Your installer should be trained in EV charger installation and certified by a body like NICEIC, NAPIT, or TrustMark. Part P compliance applies, meaning the installer must provide certification of safe work.
What happens during installation
- Your electrician assesses your consumer unit and available capacity (30 mins–1 hour)
- Cables are run to the charger location (wall, driveway, garage)
- Charger is mounted and electrically connected
- RCD protection and safety switches are installed
- Installation tested and certified (BS 7909)
- Handover with user manual and app setup (if smart charger)
Total installation time: 4–8 hours for most homes.
