Mine was installed about a month after ordering the car then sat idle for 4 months until delivery. A standard installation so no delays.
I paused the installation after ordering the car and then when I received notification of car availability I restarted the installation process (which was approx 3 weeks). My main issue was space near the meter for an isolation switch, but all in all a pretty straightforward process and free, which is great (10 years ago I had to pay £700+ for a 3kw wall charger).
blah, blah, blah
