Common Electric Vehicle Charger Questions

Below are a few common questions and answers regarding our EV charger installation service.

Most homes have single phase 230V supplies meaning the maximum power of chargers suitable are 7kw/32amps. Chargers are supplied by a 6mm cable wired directly from your fusebox/consumer unit and must be on their own dedicated circuit. Depending on the condition and capacity of your fusebox/consumer unit an additional unit may need to be installed to supply the electric vehicle circuit. A 32A charger will give 30 miles of range per hour, the size of your cars battery will determine how long it will take to charge, the industry leading Tesla Model 3 will take around 8 hours from empty.

Suppliers now offer great EV tariffs with money saving incentives, scheduled charging enables the car to be plugged in and set to charge between pre-set times like midnight and 7am to charge when the EV tariff gives the lowest price of electricity. This requires a smart meter to be fitted by your supplier. A full electric Hyundai Ioniq costs much less to run than than an equivalent petrol or diesel saloon, at around £4.80 to charge from empty to full with a range of 193 miles, costing only 2.94p per mile (based on 14p/kWh tariff).

9/10 customers go for tethered - a built in lead - as it is more convenient and allows you to keep your spare lead in the boot to use when you are away from home. Some clients prefer to have untethered - socket only - as they find the coiled leads untidy when not in use, it's a matter of personal taste and what suits you.

Unfortunately not at this point. For the time being we only cover Edinburgh and central Scotland.
