Pleasant enough people to deal with, but the whole process was rather painful, not helped by the excessive government red tape and paperwork. Biggest annoyance was that I ordered a BMW system to make use of my 3 phase into the house after much discussion and several photographs of the fuse board in the house. Firstly, Chargemaster didn't bother to mention that the BMW wallbox would be delivered to the house separate to the arrival of the installer - so we had to make special arrangements on the day to receive it. Then, when the installer arrived, he took one look at my fuse board and said that it did have 3 phase, but wouldn't work with the BMW system as a critical item was missing - which could've been easily spotted by Chargemaster - why send several pictures, then not check them for compatability? So I had 3 choices, cancel the install and fit the missing electrical parts and rearrange, fit the BMW box and not get use of the full capability, or fit a Chargemaster box that the installer had in his van! In the end, the installer made a good job, but I'm still trying to sort the paperwork regarding rejecting the BMW box and swopping to a Chargemaster box.
