Making the switch to electric has never been more popular, but many UK homeowners feel uncertain about what the EV charger installation process actually involves. Whether you’re a new EV owner or planning ahead for your first electric vehicle, understanding each step of the installation journey will help you prepare properly and set realistic expectations.
The good news? A professional EV charger installation is far more straightforward than most people imagine. With the right installer and proper preparation, most home installations are completed within 2-3 hours, transforming your property into a convenient charging hub that could save you thousands of pounds annually on fuel costs.
What Makes the EV Charger Installation Process Essential?
Installing a dedicated home charging point is one of the smartest investments any EV owner can make. Home charging is substantially cheaper (roughly one-third the cost) of DC fast-charging, and having your own charging point means you’ll wake up to a fully charged vehicle every morning.
Beyond the obvious convenience, a properly installed home charger increases your property value and positions you ahead of the curve as electric vehicle adoption accelerates across the UK. But to get these benefits, you need to understand what the installation process entails.
Pre-Installation Phase: Setting the Foundation (1-2 Weeks)
Initial Assessment and Planning
Before any physical work begins, your chosen installer will need to assess your property’s suitability. This crucial first step typically happens through either an online survey or an in-person visit.
What to expect during your assessment:
- Electrical system evaluation – Your installer will check if your consumer unit (fuse box) can handle the additional load
- Power supply analysis – Most UK homes have a 60-amp main fuse, but some installations may require upgrades to accommodate a 7kW charger
- Cable routing survey – Planning the most efficient path from your electrical panel to the installation location
- Parking area inspection – Ensuring the chosen location meets safety requirements and building regulations
As part of the installation process, your local Distribution Network Operator (DNO) must grant you approval to install a charger. Your OZEV-approved installer will typically handle this notification process for you.
Choosing Your Installation Location
The location of your charger impacts both safety and convenience. UK regulations specify that chargers must be:
- Mounted between 0.75m and 1.2m from ground level
- Positioned with good WiFi or mobile connectivity (required for smart charger functionality)
- Located within easy reach of where you typically park
- A minimum of 2 metres from any public road
You shouldn’t mount your charger on a fence or temporary structure, as this can be dangerous. Wall mounting is typically preferred, though pedestal installation may be necessary if no suitable wall is available near your parking area.
Documentation and Permits
Most home EV charger installations fall under “permitted development“ and don’t require planning permission. However, there are important exceptions:
- Listed buildings or conservation areas may need special permissions
- Leasehold properties require landlord consent
- Flats and apartments often need additional approvals
Your installer should handle any necessary permit applications and ensure compliance with all relevant building regulations.
The Installation Day: What Actually Happens (2-4 Hours)
Once planning is complete and materials arrive, the actual installation process is surprisingly quick for standard setups.
Step 1: Site Preparation and Safety (30 minutes)
Your installer begins by:
- Switching off power at the consumer unit
- Setting up safety barriers and protective equipment
- Conducting final measurements and confirming cable routes
- Preparing tools and testing equipment
Step 2: Electrical Work and Circuit Installation (1-2 hours)
The most technical part of the process involves:
Circuit Installation:
- Installing a dedicated circuit breaker in your consumer unit
- Running appropriate cabling from the fuse box to the charger location
- Ensuring proper earthing and RCD (Residual Current Device) protection
Cable Management: The longer the cable run, the more complex (and expensive) the installation becomes. For outdoor runs or routes through walls, this phase may take longer as installers ensure weatherproofing and structural integrity.
Step 3: Charger Mounting and Connection (30-45 minutes)
With the electrical infrastructure in place:
- The charging unit is securely mounted to the wall or pedestal
- All electrical connections are made and tested
- Cable management and tidy-up work is completed
- Initial power-up and functionality testing begins
Step 4: Testing and Commissioning (30 minutes)
Before handover, comprehensive testing ensures everything works safely:
- Electrical testing – Verifying proper earth continuity and insulation resistance
- Functionality checks – Testing charge initiation and stopping procedures
- Smart features setup – Connecting to WiFi and configuring app controls
- Safety verification – Ensuring all protection systems operate correctly
Post-Installation: Getting Connected and Certified
Demonstration and Handover
Conduct your first charging session by plugging in your EV and monitoring the process. Check for proper charging speed and listen for any unusual noises. Your installer should walk you through:
- How to start and stop charging sessions
- Using any smart features or smartphone apps
- Understanding status lights and error indicators
- Basic maintenance and troubleshooting tips
Certification and Documentation
Professional installations include essential paperwork:
- Installation certificate confirming compliance with all regulations
- Warranty documentation (typically 3 years for both equipment and installation)

Smart Charger Setup
Since June 30, 2022, all new home and workplace EV chargers must be “smart chargers.” Your installer will help configure:
- WiFi connectivity for remote monitoring
- Smartphone app setup and account creation
- Scheduling features for off-peak charging
- Energy monitoring and usage tracking
Timeline Expectations: From Enquiry to Charging
Understanding realistic timeframes helps you plan effectively:
Total Project Timeline: 2-4 Weeks
- Initial enquiry to survey: 3-5 days
- Survey to quote approval: 2-3 days
- Ordering equipment: 5-7 days
- Installation scheduling: 1-2 weeks
- Actual installation: 2-4 hours
For a standard home EV charger installation, it takes around 2-3 hours to install. However, complex installations requiring electrical upgrades may extend to a full day.
Busy periods (particularly after government grant announcements) can extend scheduling times, so booking early is recommended.
