As electric vehicles become more common across Exeter and the wider Devon area, more homeowners are asking the same question: how does electric car charger home installation work, and how much does it cost? With off-street parking common across our local suburbs, a home charger is one of the most convenient upgrades you can make – it lets you charge overnight, cut your reliance on public chargers, and take advantage of cheaper off-peak tariffs. In this guide, our NICEIC-accredited team explains everything you need to know about home EV charger installation, including costs, requirements, safety standards, and common FAQs.
Can You Install an Electric Car Charger at Home?
Yes, most UK homeowners can install an electric car charger at home, provided the property has:
- Off-street parking or a driveway
- A suitable electrical supply
- Space for a charger unit near the parking area
- A consumer unit that can support the additional load
A qualified electrician will assess your home before installation to confirm it is safe and compliant.
Why Install a Home EV Charger?
Home EV charging offers several major benefits:
Convenience
Charging at home means you can plug in overnight and wake up with a full battery, without relying on public charging points.
Faster Charging
A dedicated home charger is much faster than a standard 3-pin plug socket.
- 3-pin plug: very slow charging
- 7kW home charger: typical full charge overnight
- 22kW charger: faster but requires three-phase supply
Lower Costs
Home charging is often cheaper, especially with off-peak tariffs from suppliers such as Octopus Energy.
Increased Property Appeal
As EV ownership increases, having an installed charger can add value and convenience for future buyers.

What Is the Installation Process?
Electric car charger home installation is usually straightforward when handled by a qualified electrician. Here is what to expect.
1. Home Survey and Assessment
An electrician will inspect:
- Your consumer unit (fusebox)
- The electrical supply capacity
- Earthing and bonding
- Charger location and cable route
- Off-street parking access
This ensures the installation can be completed safely.
2. Choosing the Right Charger
Most homeowners choose a smart 7kW charger. Popular models include:
- Rolec
- Zappi
- Ohme
- Wallbox Pulsar
- Pod Point
Smart chargers allow scheduled charging, app control, and tariff optimisation.
3. Installation Work
On installation day, the electrician will:
- Fit the charger unit to an external wall or mounting post
- Run wiring from your consumer unit to the charger
- Install a dedicated circuit and safety protection
- Test all electrical connections
- Configure smart features if required
Most installations take 3 to 6 hours.
4. Certification and Compliance
The electrician will issue certification confirming the installation meets UK standards, including:
- BS 7671 wiring regulations
- IET Code of Practice for EV Charging Equipment
- Building control notification where required
You should always keep the certificate for future property records.
Do You Need a Consumer Unit Upgrade?
In some cases, yes. If your fusebox consumer unit is outdated or already near capacity, you may need:
- Additional circuit protection
- RCD or RCBO upgrades
- Surge protection
- A full consumer unit replacement
This is especially common in older homes.
A qualified installer will advise during the survey.
Where Should a Home EV Charger Be Installed?
The best charger location is:
- Close to your driveway or parking space
- Protected from excessive weather exposure
- Near an accessible cable route
- Within safe distance regulations from doors and windows
Your installer will help determine the safest and most practical placement.
Is Installing a Home EV Charger Safe?
Yes, when installed properly by a qualified electrician.
Home EV chargers draw significant electrical load, so safety measures must include:
