I am disappointed in the whole process. Starting from taking videos and pictures and sending them remotely to the engineer to decide about the work required as there are no visits for the engineer before the installation day. I did not imagine that I will pay more than 500 pounds for the installation. The trenching and ground work left me with a broken door step and misplaced floor tiles. The electric work was good and the engineer was very polite and professional. In summery, very expensive installation that should make every one think twice before getting an electric car.
