Thanks for the reply Burgerman
Belt and braces solution to charging indeed.Unfortunately I live in a ground floor flat and don’t have a driveway (so no home charger possible)but am able to park up at the rear of the property about 3 metres from my window so thinking of charging that way in emergencies only.I am also investigating apps like co charger but the rates people want near me seem rather extortionate at the moment! Only just beginning to look at wether an ev will suit me costs wise and any tips/recommendations are most welcome.
