For me it was crucial to be able to charge from home, for 2 principal reasons, cost and convenience. I couldn’t get my head around having to search for charging stations all the time and secondly to pay typically 50p kWh. The latter includes VAT at 20% and the government could zero rate this, for say 2 years reducing the vist by almost 17% at a stroke.
I paid £999AP for my Kona, now £1599 and I would still purchase it again. A comparable petrol car would typically have a similar or higher AP and there will always be deals that offer cheap overnight charging. However the gap has narrowed to the extent that the government will need to act. And bear in mind if both petrol and electricity were supplied without taxes, a litre of fuel would be around half its current price. Interesting times lay ahead.
