I've watched a few of his videos on YouTube and his charging one did spook me!We do about 11K mile p.a.
For public charging try not to follow the herd! like that idiot MacMaster
Service stations are (mostly) still poor - Use Zapmap and ABRP to identify places with more than 1 or 2 chargers
e.g. this is just off the M4 - great cafe, a shop and 4 Instavolt's
Three trees cafe
Consider an Elli card
Some Tesla chargers can be used - install the app
