The fixed rate tariff has three different rates for electricity: peak, off-peak and super off-peak.
The times and rates for each are as follows:
- Peak (4pm-7pm) – 38.48p/kWh
- Off-peak (5am-4pm and 7pm-2am) – 20.11p/kWh
- Super off-peak (2am-5am) –16.33p/kWh
The idea is that consumers use super off-peak or off-peak times to charge electric cars and other devices, and also use appliances such as washing machines and dishwashers.
The higher-cost period from 4pm to 7pm reflects higher national energy use at this time.

E.ON said the tariff will allow customers to “take control” of their energy prices by shifting their usage to off-peak times.
Time-of-use tariffs are usually aimed at customers with ‘home solutions’ such as electric vehicle (EV) chargers and heat pumps, but Next Smart Saver is aimed at everyone.
Prices are valid at the time of publishing and subject to change. They are based on the national average and will vary by region. Customers must have a working smart meter and consent to sharing half-hourly data to be eligible for the tariff.
The tariff doesn’t have any exit fees, meaning customers have flexibility if their circumstances change.
Ramona Vlasiu, chief operating officer at E.ON Next, said: “With energy prices fluctuating, we know customers are looking for ways to take control of their bills.
“The Next Smart Saver tariff – the UK’s first fixed mass-market time-of-use tariff – is designed to do just that, rewarding customers who can shift their energy use to times when demand is lower, helping them save on their bills.
“However, this isn’t just about individual savings; it’s about smarter energy use for the whole country. As the UK moves towards a greener, cleaner grid, shifting demand away from peak times will play a crucial role in reducing strain on the network.”
