E.ON Next Pulse Review 2026: EV Tariff vs Octopus Go

LAST REVIEWED 2026-09-06

How is E.ON Next Pulse structured?

E.ON Next Pulse is a time-of-use tariff designed for electric vehicle owners. It offers a cheaper electricity rate during off-peak hours, typically overnight, when demand is lower. The tariff has two rates: a higher peak rate during the day and a lower off-peak rate at night. This structure encourages shifting energy use to off-peak times, which can lower bills for those who charge their EV overnight.

The off-peak window is usually around 6 hours, but exact times may vary by region and smart meter setup. E.ON Next Pulse requires a smart meter to track usage accurately. The tariff is available to new and existing customers, but eligibility may depend on having a compatible EV charger or being able to provide evidence of EV ownership.

Compared to standard variable tariffs, Pulse offers a lower off-peak rate but a higher standing charge. This means the benefit depends on how much electricity is used during off-peak hours. For typical EV drivers charging overnight, the savings can be significant, but for low users, the higher standing charge might outweigh the benefits.

What are the April 2026 rates and what do they mean?

As of April 2026, E.ON Next Pulse rates are not published in the provided tables. However, the Ofgem price cap for typical dual fuel from July to September 2026 is £1,663, and from October to December 2026 it is £1,723, a 4% increase. These figures give a benchmark for standard variable tariffs. Pulse rates are likely to be competitive, but exact numbers are not yet confirmed.

The price cap affects standard variable tariffs, but Pulse is a fixed or variable tariff? Typically, Pulse is a variable tariff, meaning rates can change with market conditions. The cap does not directly apply to Pulse, but it influences the market. If the cap rises, Pulse rates may also rise.

When comparing, look at the unit rates for peak and off-peak, and the standing charge. The off-peak rate should be significantly lower than the peak rate to make it worthwhile. Also, consider the duration of off-peak hours: longer windows allow more charging at the low rate.

How does E.ON Next Pulse compare with Octopus Go and Intelligent?

Octopus Go is a popular EV tariff with a low off-peak rate, typically 4 hours overnight. Intelligent Octopus Go offers even lower rates but requires a compatible charger and allows Octopus to control charging times. E.ON Next Pulse offers a longer off-peak window, often 6 hours, which can be more flexible.

In 2026, the rates for these tariffs are not published in the provided tables. However, historically, Octopus Go has offered a very low off-peak rate, sometimes around 5p/kWh, while E.ON Next Pulse has been slightly higher but with a longer window. The standing charges also differ.

For a typical EV driver using 2,500 kWh per year for charging, the total cost depends on the off-peak rate and the number of hours. If Pulse offers a 6-hour window at a slightly higher rate, it may still be cheaper than Octopus Go's 4-hour window if the rate is lower. But if the rates are similar, the longer window is beneficial.

Who is eligible for E.ON Next Pulse and how to switch?

Eligibility for E.ON Next Pulse typically requires a smart meter and an electric vehicle. Some tariffs may require a specific type of EV charger, such as a smart charger that can be remotely controlled. E.ON may ask for proof of EV ownership, such as a V5C logbook.

To switch, a customer can contact E.ON Next directly or use a comparison site. The switching process usually takes a few weeks, and the new tariff starts after the old one ends. There may be exit fees on the current tariff, but these are often waived if switching within the same supplier.

Before switching, check the current energy usage and charging habits. If the EV is charged mostly at home overnight, Pulse could be beneficial. But if charging is done elsewhere or during the day, the peak rate may be higher than a standard tariff.

What is the practical setup with a smart charger?

To get the most from E.ON Next Pulse, a smart charger is recommended. A smart charger can be programmed to start charging during off-peak hours automatically. This ensures the EV is charged at the lower rate without manual intervention.

The setup involves connecting the charger to the home Wi-Fi and linking it to the E.ON app. The app can show real-time usage and costs. Some chargers allow scheduling, while others may be controlled by the energy supplier remotely.

If the charger is not smart, the user must manually start charging after the off-peak window begins. This can be inconvenient but still works. E.ON may offer incentives for installing a smart charger, but this is not confirmed.

Is Pulse suitable for heat pumps and other off-peak loads?

E.ON Next Pulse is primarily designed for EV charging, but it can also benefit other off-peak loads like heat pumps, storage heaters, or washing machines. The off-peak window allows these appliances to run at a lower rate, potentially reducing overall energy costs.

For heat pumps, which often run at night, the off-peak rate can be advantageous. However, heat pumps may need to run during the day as well, so the peak rate applies. The suitability depends on the heat pump's usage pattern.

If a household has a heat pump and an EV, Pulse could be a good fit. But if the heat pump runs mostly during the day, the peak rate might be higher than a standard tariff. It is essential to estimate the proportion of electricity used during off-peak hours.

When is Pulse the wrong choice?

E.ON Next Pulse may not be suitable for households with low electricity usage or those who cannot shift usage to off-peak hours. If the off-peak usage is minimal, the higher standing charge could make the tariff more expensive than a standard variable tariff.

Also, if the EV is charged at work or public charging points, the home off-peak rate is less relevant. In such cases, a flat-rate tariff might be simpler and cheaper.

Furthermore, if the household has solar panels and a battery, the interaction with Pulse needs careful consideration. The battery might be charged during off-peak hours and used during peak times, which could be beneficial, but the tariff's structure may not align with solar generation.

How do heat pumps and home batteries interact with Pulse?

Heat pumps and home batteries can work well with E.ON Next Pulse. A home battery can be charged during off-peak hours and discharged during peak times, effectively shifting energy use. This can increase savings, especially if the battery is large enough to cover daytime usage.

For heat pumps, the off-peak window can be used to preheat the home or water, storing thermal energy. This is particularly effective with underfloor heating or hot water tanks.

However, the interaction depends on the control systems. Smart home systems can automate these processes, but manual control may be required. The tariff's off-peak hours must align with the battery and heat pump schedules.

What is one detail in the small print to know?

One important detail in the small print of E.ON Next Pulse is that the off-peak hours may be subject to change. E.ON can adjust the times, and they may not always be the same throughout the year. This could affect the savings if the user's schedule changes.

Another detail is that the tariff may require a minimum usage or a specific type of meter. Some tariffs have a minimum contract length, and early exit fees may apply.

It is also crucial to note that the rates are not fixed and can vary with market conditions. The price cap does not apply to Pulse, so rates could rise more than the cap.
