Charging of any vehicle, cars or scooters, when left for a long time and unattended seems to be a real fire issue. I wonder if location of any charging point should then be considered – not near flammables, easy access for fire brigade to get water and service to, and if in a garage (which most new places do not have) not surrounded by all sorts of junk. Billing for an owner’s with an in-garage power-point most often is not linked to the common property account but you’d need check that for sure.
