Very efficient booking service, friendly point of contact and given information on types of charger. Decided to go for tethered charge point for convenience. Contacted the day before installation by engineer, very polite gave me arrival time and idea for time required to fit. Arrived on time, explained what the installation would involve and discussed positioning. Explained types of charger and confirmed my choice of thethered, gave me an opportunity to change my selection if I wanted ( carried a selection of charge units on his van). Worked efficiently and finished on time, explained operation of charger and gave me an envelope with manual, guarantee and electrical sertification. Very pleased with Chargemaster’s service, only negative comments would be, took three weeks from first contacting Chargemaster to earliest install date (my garage told me it would take about 6 days. Also the tethered charger would be better with an extra metre of cable, the unit is clearly designed to accommodate a longer cable, l feel Chargemaster is penny pinching, at lease give the option for longer tethered cable.
