I suspect you would have to jump through all the hoops if you bought a charger privately. It only seems daunting because you don’t do it very often. Just do it step by step, it isn’t that complicated.
Not really mate. For example After a call, I go out to do a quick assessment and discusion with customer, which invoves a choice of chargers and email a quote the same or next day. No different to getting a quote for a new boiler, double glazing etc.
