Charging on a standard outlet gets you a handful of miles an hour. A Level 2 charger fills the battery overnight. OSB installs home and workplace EV charging across Sunderland, including the load calculation your panel actually needs.
“The dispatcher actually understood what I was describing on the phone and told me which breaker to shut off before they arrived.”
“The quote they gave me on the phone was the number on the invoice. That is apparently rare and it shouldn't be.”
“Bought an EV and had no idea what my panel could handle. They did the load calculation, told me straight that I had room, and installed the charger two days later.”

Yes — hardwired, commissioned, and set to the right breaker size for your vehicle and panel.
