I was with British Gas prior to getting an EV. I was aware the meter wasn’t communicating with them so tried to get it changed. BG was less than helpful and said they were aware of the problem but had no idea when the meter could be swapped. They did invite me to lodge a formal complaint even though they admitted it would make no difference. Long story short, I switched to Octopus and the meter was changed within 2 weeks. Happy days.
