Long application process, which asks lots of questions, thankfully the website does seem to save your progress as you go which was a relief as I had to ask for advice and help at some points. All the questions, though, do seem to help massively with the installation. They arrived early and had completed the job in less than an hour so were gone before they had even technically been meant to arrive which was impressive. The charger has been working perfectly since, and is much better than using the domestic plug which I had to muddle through with whilst I was stuck with for a couple of weeks whilst I waited for the install. Happy customer so far, and I would recommend then for their ruthless efficiency!
