One thing to also keep in mind is that it is forecast that the UK's electricity production needs to increase by 70% by 2050 just to meet demand from electric vehicles. It is said to be equivalent to 6 extra nuclear plants. [1]

As the government announced that sales of new ICE vehicles will be banned in only 9 years and most car manufacturers start unveiling their EV range in earnest I think we're going to see the shift to EV happen this decade. If so extra electricity production needs to happen now.
