Good luck in Wales :roll: it's pretty scant! A few rapids on M4 / A55 but that's about it. Type 2 chargers at destinations and car parks. I have Ecotrcity App for rapids. For others I carry chargemaster / polar RFID and have PodPoint App. If you're planning on being in South Wales and need any tips, just ask.
Those from the other regions can probably better advise on their areas.
