I kinda suspect there’s a premium once you mention “EV vehicle”, since you’re signalling that you’re affluent enough to afford an EV and have committed to spending the money required to get EV charging at home working, etc. (Kinda like getting a quote for anything wedding related.)

I’m getting some wiring run about the same distance (to my attic, fished up a wall, with moderately poor access) for non-EV purposes next week and the quote was a few hundred dollars.
