I regularly drive to Cornwall and back from the Northwest of England, with some driving in Cornwall as well. In the Skoda Enyaq using Tesla I spend around £110 plus maybe £7 charging up at home before I go and another £5 when I get back.
In the previous Octavia 1L mild hybrid I would put £70 in before we left, another £50-£60 driving around Cornwall and then another £70 filling up when we got back. If you choose the cheaper charging options it still works out cheaper. The big saving as Dumfries points out, is your filling up cheaply before you go and cheaply when you return.
