An ordinary socket working for other appliances does not establish that it is suitable for hours of EV charging. Electrical Safety First recommends a dedicated chargepoint and highlights the sustained load on sockets and wiring.
If you are considering a portable charging lead, check the vehicle manufacturer’s instructions and ask an electrician to assess the socket and circuit. Use suitable equipment from a reputable source. Do not make up the distance with domestic multi-socket extension leads or join extension leads together.
Stop using damaged charging equipment. If there are signs of overheating, a burning smell or repeated tripping, get the installation checked before charging again.
A dedicated charger gives us a properly assessed circuit and a practical place to charge. Any insurance conditions depend on your own policy; ask your insurer if you are unsure. We cannot make a general claim about what most insurers require.
