Electrical Services in London, ON
London, Ontario electricians serve Middlesex County including Western University and Fanshawe College communities. Most older London homes have 100-amp panels original to 1950s-80s construction; modern households with central AC, EV chargers, and heat pumps typically need 200-amp upgrades quoted at $3,000-5,000 CAD. Local electricians hold ECRA/ESA licensing as Ontario master or journeyman electricians. London permits and inspections cover most electrical work, with London Hydro providing electric service.
London's older Old North and Old South homes often have knob-and-tube wiring requiring careful evaluation before service upgrades. Ontario's strong EV adoption drives heavy demand for Level 2 charger installs. Save On Energy plus federal Greener Homes credits drive concurrent demand for electrical work.
