Most electric cars can be charged at home from any standard British 13amp socket, using a cable which most electric cars come with. It's as easy as charging your phone. Faster sockets, commonly "Type 2' outlets, can be installed at home or work; often for free or cheaply with support from Government Grants.
Away from home, public chargers are available up and down the country, and there are currently over 11,000 available. There are a few different companies that provide the charging facilities and customers need to register with a charging provider in order to use them.
