E.ON Next Drive

E.ON Next Drive stands out for having the longest off-peak window of any EV tariff on this list: a full 6 hours from midnight to 6am. At around 7.5p/kWh, it's very competitive with Octopus offerings, and the extended window means you can easily fully charge any Tesla from empty overnight — even a Model S with its larger battery. The peak rate of 28.64p/kWh is also one of the lowest, making it a good all-round tariff.

Best for: EV owners who want the longest possible off-peak window and a competitive peak rate for household electricity.

How It Works

E.ON Next Drive gives you a 6-hour off-peak window every night. Set your charging timer to start at midnight, and you have until 6am to charge at the reduced rate. On a 7kW charger, that's 42kWh of charging capacity — enough to fully charge any Tesla model from nearly empty. The simplicity is the selling point: no smart charger needed, no vehicle API, just a timer.

Who It Suits

This tariff is ideal for high-mileage drivers or those with larger battery vehicles (Tesla Model S/X) who need to add significant range overnight. The 6-hour window is also forgiving if you forget to plug in right at midnight — even starting at 1am gives you 5 hours of off-peak charging. It's also strong for households that use a lot of electricity in the early morning (breakfast, heating), as the off-peak rate extends to 6am.

Cost Breakdown

Compatible Chargers

E.ON Next Drive works with any home charger. The 6-hour window is generous enough that even basic chargers with simple timers have plenty of time to complete a full charge. The Tesla Wall Connector with its built-in scheduling is a natural fit. If you're on this tariff, you're paying for simplicity and window length rather than smart features.
