A home EV charger is a dedicated electrical circuit running from your consumer unit to a wall mounted unit, usually on the side of the house or garage. The charger itself is just a smart box that meters the electricity and talks to your car, the real work is the cable run, the protection, and the certification.
For 99% of Fraserburgh homes the right choice is a 7.4kW charger on a single phase 32A circuit. That delivers about 25 miles of range per hour of charging, more than most daily commutes need. A 22kW charger requires a three phase supply that most UK domestic properties don't have, and the SSEN upgrade to three phase runs from a few hundred pounds to several thousand depending on the work.
Tethered chargers (Zappi tethered, Ohme Pro, Andersen tethered) come with a fixed cable attached, easy to use, no separate cable to store. Untethered chargers (Easee, Zappi untethered, Andersen untethered) have a Type 2 socket that you plug your own cable into. Untethered is slightly cheaper, future proof if you change cars, and looks cleaner when not in use. Tethered is more convenient day to day.
Every install includes a Type B RCD or RCBO (because EV chargers can produce DC fault current that ordinary RCDs miss), a dedicated isolator, surge protection where the supply allows, and full BS 7671 certification. We notify SSEN where the load is over 7.4kW or where DNO consent is required.
