Here's quite a good article.

In summary, the numbers quoted mean that EVs account for only 0.52% of all cars on the road in the UK, and there's 1 non residential charger for every 9 EVs - which would be great if it was 1 for every 9 cars, if there were 10 million EVs on the road, but just shows how sparsely distributed they are with 17k non residential chargers across the country. 36% of all UK homes have no access to parking on their own property.
We are nowhere near ready for the mass ownership of EVs, unless you've got your own driveway/garage and can rely on at-home charging for the vast majority of their charging, and can do that charging outside peak grid demand hours. If you do have to do journeys beyond your car's range, you're going to have to be sure of your en-route charging choices and stomach a wait at that charger.
Subsidies for take-up of EVs are drying up as more people take advantage of a finite pot set aside. Meanwhile, these EVs are conveniently overpriced by the amount of the subsidy - every tax payer is funding that.
Early adopters are always overcompensated - the early adopters of solar panels had to pay a lot out for the kit, but were getting 40p off the grid for every kWh generated, when the going rate on your electricity bill was 10p per kWh - every other consumer of electricity is propping up that incentive.
A mate of mine got a "free" charging point fitted about 4 years ago, to future proof his house. He has no intention of getting an EV in the foreseeable - by the time he needs that charging point it will probably be obsolete. A colleague's husband is a sparky and was contracted to fit the charging points locally. In his opinion, the hardware is worth about £150 at retail, with an hour to install. Some quango is creaming off £300 on the current £500 Grant, £800 when the grant used to be £1000 per charging point.
In my mate's contract for his charging point, there is a clause that obliges him to make it available for public use if requested. How they would reimburse him for someone else using his electricity to charge their car is not clear.
