My experience with BP Chargemaster was essentially very good. They are very efficient albeit they must be facing increasing demands for their services. However things necessarily took longer than I initially thought it would. There were a number of technical issues to resolve and they probably vary from one installation to another. I was given some options which meant I had to explore options which would have to be provided by either my electricity supplier and distributor. In the end I got an electrician to visit and he came up with a better, quicker and cheaper option. BP chargemaster could do with considering this option as I could imagine others might not have spotted this 'shortcut'.
