I edited the post once i rechecked all the figures as below some serious savings to be had.Sounds plausible. So your 15,000miles/year is 4,213kWh, which at 9p/kWh is £379 not £1349. So that gets you into the roughly £100/month saving area that you were looking for.
And if you are going to start adding in what the tax might be in 2025 then you can use electricity prices from a new contract, like the 7.5p Octopus one I mentioned, or Ovo's 7p plan which would save you another £84/year.
Plus of course if you were just comparing EV vs fossil like for like, any new-to-you diesel car would be paying at least £190 road tax.
As for the fossil comment that is a bit harsh its fully LEZ complaint low emission diesel, not quite a fossil and having had the pleasure of a few contry roads last few days still drives very nicely and huge fun, big part of why i bought it.
I apologised for the gross error in my figures not sure what happened the revised figures should be correct.
Well I have done some digging and researched this properly now

This totally changes how I look at EVs now.
Only problem is actually finding a used EV as they sell as soon as they arrive and new is just too expensive.
Auto Car had a good article on the VW ID3 should be a great car, but plagued with tech glitches and tested price is over £50k for what is meant to be a mainstream replacement for the Golf size car.
