I experienced extremely poor customer service from BP and would not recommend them. They cancelled the installation twice with only emails at the last minute as notification. I lost two days pay due to being messed around. They can't even be bothered to call to notify they won't be turning up. If your not glued to your emails then that's tough. The planning and scheduling team are incompetent and have no interest in customers. The engineer on the other hand was very helpful and did a great job installing. If your looking at getting a wall box installed then source an independent as all BP are interested in is overbooking as many jobs as possible and overstretching their engineers. The customer service is actually quite shocking in this modern times.
