For most EV owners, home charging is where the real story begins. Plug in at night, wake up to a full battery, never visit a forecourt for routine refuelling. Here is exactly how to set it up and what to know before you start.
Three-pin plug or home charger?
A three-pin socket adds around 8 to 10 miles of range per hour functional for light daily use, but not designed for nightly EV charging.
Sustained overnight charging from a domestic socket degrades the socket over time and presents a risk in older properties.
Most EV manufacturers recommend a dedicated home charger for regular charging. Use a three-pin plug for emergencies. Install a wallbox for daily use.
What home charger installation involves
A 7kW smart wallbox, installed by an OZEV approved electrician, is the standard solution.
The installer surveys your property, confirms your consumer unit can support the load, routes the cable, and commissions the unit. Installation typically takes two to four hours on a straightforward job.
Get a site survey before committing to the vehicle purchase if you have any uncertainty about your property surveys are usually free.
All home charger installations must use an OZEV approved installer. Check the government register at gov.uk before booking.
Off-peak tariffs the charging cost game-changer
Several UK energy suppliers offer EV-specific tariffs with significantly cheaper electricity overnight when grid demand is lowest.
A smart charger scheduled to run during the off-peak window charges the car at a fraction of the standard daytime rate.
This is how home EV charging becomes dramatically cheaper per mile than petrol. Research available tariffs from your supplier and competitors before buying your EV.
Home insurance
When a home charger is installed, inform your home insurer. A new electrical installation is a material change to your property.
Most insurers accommodate this without significant premium increases for a properly installed unit but failure to disclose is a ground for rejecting a related claim.
