Excellent. The communication was good, the installer - John from Hull was on time and polite. He took the time to discuss my options before starting the work, something I feel was very important. He was clearly qualified and competent, as well as being tidy and respecting my home. He also answered my questions with a keen interest on the subject of EV's. I feel John was as decent and friendly as I could have wished for, and exceeded all of my expectations. My installation was financed by OLEV and Renault, and would have been fairly expensive if I had paid, but then the unit cost and an electrician for half a day is expensive - so I can't complain and certainly wouldn't want a company who cut corners to save a few quid. The unit was tested (for functionality with a test rig) by John, and clearly explained how to use it (as well as being given full instructions on paper, and a full electrical works certificate, and I witnessed electrical tests on the circuit during installation). The first time I used the charger it worked flawlessly - plug in and it charges! Clearly John installs in a professional manor, presumably to Chargemasters usual standard, however I do feel he went above and beyond what i'd expect from any tradesman.
