I haven't had a chance yet to try out the charging unit as our car order has been delayed by Covid. The process of communicating with the Chargemaster team was fraught with difficulty and lack of response. When responses arrived they were often contradictory and unhelpful and I was unable to get an estimate of costs in advance or a breakdown of costs when payment was demanded. Phone calls were rarely answered by the relevant person and often emails were standard responses and irrelevant to the situation. I explored changing to a different supplier but in the end stuck it out. The best bit was the engineer who installed the unit who was amazing: prompt, efficient, polite, competent and tidy.
