Re: Answering a few points in the comments...
"Our EV works out cheaper by far than the car it replaced. We pay less now including the repayments for the car and all fuel and servicing, etc. than we did for just the fuel on the car it replaced"
How much would it be costingt if you didn't get the £5K (or more?) subsidy to buy it (we're all paying), plus the grant for updating your charging point (that we're all paying) and the goverment started taxing EV charging to recoup some of their lost diesel/petrol taxes?
As before, with the current level of subsidies EV makes sense now for a lot of people, but if the number of people going electric vastly increases the govt won't be able to maintain the current level of subsidy.
