Perhaps I’m being a bit harsh but had several quotes to supply and install the Zappi charger. All around £1200 to £1500. Watched the guy install - took about 3 hours (including him talking to his base). The charger itself, I believe is around £700 so these guys are on at least £100 per hour allowing for VAT. Seems like a good gig if you’re booked in for several of these in the week. Maybe I’m just out of touch with what electricians charge these days.
