EV Car Charger FAQ
Which home EV charger should you choose?
Home electric car chargers fall into 2 categories; Trickle chargers and AC chargers.
A trickle charger plugs into the mains supply using a standard, 220v 3-pin plug on one end. A trickle charger can deliver anywhere between 8-10 miles of range to the battery per hour. They are not overly practical unless you only drive short distances every day, or top-up every night as it can take anywhere from 12 – 24 hours to fully charge a battery pack.
AC chargers (sometimes known as Wallboxes) are a much better option for most EV owners and are often installed in homes, offices, and other commercial settings. These electric car chargers have power outputs of 3.7kW or 7kW. The latter will charge most EVs from empty to full range in around 8-10 hours.
Commercial settings with a 3-phase power supply can also install 22kW electric car chargers with even quicker charge times, these are known as DC chargers.
What is an EV fast charger?
An EV fast charger is an electric car charger that can charge your car’s battery from empty to nearly full in around 40 minutes. These EV charging solutions are in public places (such as motorway service stations or dealerships) and using DC, deliver anywhere from 50kW to 200kW of power. Due to their very high installation cost and power consumption, they are not economical for homes or most workplaces.
How much does an electric car charger cost?
Home or workplace electric car chargers can vary in price but they typically start at around £400 to £500 and can go up to £4000 depending on power output and features etc.
If you only use public and paid chargepoints, you could save in the region of £1000 over a year with a home chargepoint. Despite the initial costs, they often pay for themselves quite quickly.

What is a tethered electric car charger?
The other big distinction between EV chargers is whether they’re tethered or untethered. A tethered electric car charger has an integrated charging cable. In simple terms, that means the cable is permanently attached to the wallbox.
An untethered electric car charger has a socket in which you plug the charging cable into, much like a camping socket. we install both types of EV charger to suit your needs.
