JLR said it would retrain "thousands of highly skilled automotive engineers and production employees, who previously worked on the development of internal combustion cars, to specialize in electrification, digital and autonomous cars."
EV sales have risen sharply in Europe over the last two years and looming fossil-fuel car bans mean more are coming.
JLR has previously said that Jaguar, the smaller of its two brands, will be entirely electric by 2025, while Land Rover will get its first fully electric model in 2024.
JLR has developed its own training materials in cooperation with the University of Coventry and the University of Warwick.
"Plant employees at all levels will require training to ensure they can work safely alongside the high voltage systems," JLR said.
Karl "Freddy" Gunnarsson, an engineer who worked at JLR on diesel and gasoline catalytic converters, has already retrained and is working on a team dedicated to increasing EV battery density to maximize vehicle range.
"This (EV range) is what we are going to be competing on, Gunnarsson said. "So, on this side of the business you can feel the excitement all the way up to the CEO."
JLR has struggled in recent months as semiconductor shortages have hit deliveries of its luxury SUVs and sports cars.
Automakers around the world have been working to re-skill workers as they ramp up electrification plans. In July, Mercedes-Benz Group said it would spend more than $1.25 billion on training staff through 2030.
