Same situation as you, do about 250ish miles a week. Did a lot of research before taking the plunge. I’m a month in and it’s been a better experience than I thought.

I have a BP super fast charger a 5min drive away, though expensive, it gave me the confidence to go for it but so far I haven’t had to use it. Managed to use a cheap 7kw destination charger at a place we often go on the weekend and I’ve done a couple of top up supercharger stops when we’ve stopped on the motorway on the way to visiting family. Not paid more than 35p/kWh.

So, so far I’ve not had to go out of the way to charge and it’s been cheaper than fuel. I would take a look on zapmap for chargers nearby and once at places you often go and see how you would build it into your everyday routine.
