How EV Tariffs Work | |||||||||||||||||||||||||||||||||||
| EV tariffs split the day into off-peak and peak periods. You charge your car overnight during the cheap off-peak window (typically 11pm–5am or midnight–6am) at a significantly reduced rate. During the rest of the day, you pay the standard rate for household electricity. A smart meter and usually a home EV charger (7kW wallbox) are required. | |||||||||||||||||||||||||||||||||||
