Electricity tariffs
Which night rate charges the car cheapest
Every supplier prices the same kilowatt-hour differently depending on the hour. At EV mileage that gap is worth hundreds a year — this puts your own mileage through each published tariff.
Your Details
Average EV: 14-18 kWh/100km
Tip: To maximize savings, charge overnight during the night rate hours (typically 23:00-08:00). Most EVs let you schedule charging to start automatically at night rates.

How to Maximize Your Savings
Schedule night charging
Use your EV’s timer or home charger to start charging at 23:00. This ensures 100% of charging is at the cheap night rate.
Check Your Smart Meter
Most night rate tariffs require a smart meter. Contact your supplier to request installation if you don’t have one yet.
Switch Regularly
Suppliers change rates frequently. Check every 6-12 months and switch if you can save €100+/year.
Consider Solar
If you work from home, rooftop solar can provide free daytime charging and further reduce costs.
