How this is worked out
The energy is your car's real-world use per km, plus a tenth for what's lost while charging. The unit rates include VAT: a standard 24-hour rate of 34.38c a kWh, a night rate of 15.42c, and an EV tariff's cheap window at 8.84c. Standing charges are left out. Petrol and diesel are at pump prices of about €1.98 and €2.15 a litre. It's a guide to plan with; your own bill has your rates.
What moves it
- Your tariff, more than anything.
- Winter, when every car uses more.
- Public fast charging, which costs more than home.
