E.ON Next Pumped

Heat pump time-of-use tariff with super off-peak window.

Tariff availability, rates and terms were checked on 22 July 2026. They are a dated snapshot, so confirm the address-specific quote before acting.

E.ON Next Pumped is a 12-month fixed time-of-use electricity tariff from E.ON Next for homes with a heat pump or an electric boiler. It splits the day into three price tiers: a cheap super off-peak rate overnight from 22:00 to 06:00, a middle off-peak rate across most of the rest of the day and a higher peak rate from 16:00 to 19:00. The tariff covers electricity only. E.ON Next backs the supply with Renewable Energy Guarantees of Origin (REGO) certificates and describes it as 100% renewable. There are no exit fees.

Super off-peak, off-peak and peak hours

The day divides into three periods, with the cheap super off-peak block running for eight continuous hours overnight.

Period Hours Rate level
Super off-peak 22:00 to 06:00 (8 hours) cheapest, well below the standard variable rate
Off-peak 06:00 to 16:00 and 19:00 to 22:00 (13 hours) below the standard variable rate
Peak 16:00 to 19:00 (3 hours) above the standard variable rate

That leaves 21 hours a day priced below E.ON Next’s standard variable rate and only three hours above it. The single eight-hour overnight block is the feature that sets Next Pumped apart from tariffs that break their cheap hours into shorter slots.

Unit rates and standing charge by region

E.ON Next gives the unit rates and standing charge through a quote for a specific address, and they vary by region and tariff version. Community-reported figures from earlier versions are not a substitute for that quote, particularly after the July 2026 price change.

The advertised saving and its assumptions

E.ON Next advertised a saving of about £188 a year for its current V13 tariff at this review. It is a modelled estimate rather than a guaranteed saving.

The calculation compares Next Pumped against a standard variable rate of 26.11p per kWh, described as a national average from 1 July 2026, for a home using 5,766.67 kWh of electricity a year. It assumes 21% of that use falls in the super off-peak window, 60% in the off-peak periods and 19% at peak. Shifting only a fifth of consumption into the cheapest hours is a modest assumption. A heat pump timed to run overnight can move more than that into the super off-peak block, which improves on the figure behind the quoted saving.

Eligibility and the half-hourly data requirement

To take Next Pumped a household needs a heat pump or electric boiler already installed or planned, a working second-generation smart meter (SMETS2 or later), payment by monthly Direct Debit and an online account. E.ON Next will fit a smart meter where there is not a suitable one already. Homes on Smart Pay As You Go prepayment cannot take the tariff.

The tariff bills on when electricity is used, so it needs a smart meter sending half-hourly readings and the customer’s consent to collect them. Withdraw that consent and the account moves off Next Pumped, because E.ON Next can no longer apply the time-of-use rates.

Why solar export pays less on Next Pumped

A home with solar panels cannot pair Next Pumped with E.ON Next Export Exclusive, because E.ON excludes time-of-use import tariffs from that offer. At this review the broadly available in-house alternative was Next Flex Export at 6p per kWh. The exact export offer should be checked alongside the import quote, because an attractive cheap window can be offset by giving up a higher export rate.

How it compares with Octopus Cosy

Next Pumped is usually weighed against Octopus Cosy, the equivalent heat pump tariff from Octopus Energy. Both put their peak in the same 16:00 to 19:00 window, and neither charges an exit fee. The difference is in how each shapes its cheap hours.

Next Pumped Octopus Cosy
Term 12-month fixed variable
Exit fee none none
Cheap hours one 8-hour super off-peak block (22:00 to 06:00) plus off-peak 06:00 to 16:00 and 19:00 to 22:00 three shorter blocks: 04:00 to 07:00, 13:00 to 16:00 and 22:00 to 00:00
Peak 16:00 to 19:00 16:00 to 19:00

Octopus prices Cosy against a day rate: its cheap periods sit about 51% below that day rate and its peak about 50% above. Next Pumped gives one long overnight block, while Cosy spreads three shorter blocks across the day, including one in the afternoon.

Suitability for heat pump, EV and battery setups

For a heat pump running steadily overnight, or a heat pump paired with an EV charged in the same hours, the single eight-hour block on Next Pumped covers both without splitting the load. Owners with a home battery sometimes prefer Cosy, because its three separate cheap windows let the battery recharge more than once a day. Owners moving off a fully variable tariff such as Octopus Agile take Next Pumped’s fixed rates to remove exposure to intraday price swings over winter, accepting a fixed off-peak rate that is not the cheapest possible in exchange for removing that volatility.

Gas supply and the separate flat-rate heat pump tariff

Next Pumped covers electricity only. A household that also buys gas from E.ON Next takes it on a separate tariff, usually Next Flex or a fixed gas rate, and the time-of-use pricing does not apply to the gas.

E.ON Next may also offer a separate flat single-rate heat pump tariff, distinct from the time-of-use Next Pumped. If you are quoted a heat pump tariff, check whether it is the time-of-use Next Pumped or a flat-rate product, because the two suit different usage patterns.
