Compare typical overnight EV rates, understand how smart charging works, and see where the biggest household savings can come from.
How EV tariffs work
EV tariffs provide lower electricity unit rates during specific overnight windows when demand is lower. If you can shift vehicle charging into that window, cost per mile drops sharply.
Most suppliers require a smart meter, and some tariffs include managed charging features that automatically schedule charging for lower cost periods.
21:00 to 23:30: Standard evening rate
23:30 to 05:30: Low overnight EV rate window
05:30 onwards: Daytime standard rate resumes
