E.ON Next Pumped tariff rates 2026: confirmed rates for every UK DNO region
E.ON Next Pumped provides 21 hours of below-cap electricity daily: 8 hours of super off-peak from 22:00–06:00 and 13 hours of off-peak from 06:00–16:00 and 19:00–22:00. The exact rates vary by DNO region. This page shows the current confirmed figures for every UK region, sourced directly from the tariff database.
Overview
E.ON Next Pumped (currently Next Pumped Fixed 12m V1, effective from May 2026) is one of the most generous heat pump tariffs by total cheap-hour coverage. It provides 21 hours of below-cap electricity daily, split across a super off-peak overnight rate and a standard off-peak daytime rate, with a peak rate only during 16:00–19:00.
Rate structure:
- Super off-peak: 22:00–06:00 (8 hours) — the cheapest rate, designed for overnight hot water and heating preheat
- Off-peak: 06:00–16:00 and 19:00–22:00 (13 hours) — below the standard cap, covers most of the heating day
- Peak: 16:00–19:00 (3 hours) — above the standard cap, but significantly lower than Cosy Octopus's peak rate
There is no exit fee — Next Pumped is a variable tariff you can leave at any time.

How the rate structure works
Super off-peak (22:00–06:00): At approximately 8.00p/kWh in Eastern England, this is the cheapest rate among major dedicated heat pump tariffs. Eight hours overnight gives ample time for hot water cylinder reheating and a full space heating preheat before the morning.
Off-peak (06:00–16:00 and 19:00–22:00): Thirteen hours of below-cap electricity means most of a heat pump's daytime heating demand falls in a discounted band by default — even without active scheduling. The off-peak rate of approximately 26.30p/kWh is below the Ofgem standard cap, so any heating during these hours costs less than it would on a flat-rate tariff.
Peak (16:00–19:00): The peak rate of approximately 33.34p/kWh is above the cap but significantly lower than Cosy Octopus's peak of 52.88p/kWh. Running a heat pump during this window on Next Pumped costs notably less than the equivalent on Cosy, making it a lower-risk tariff for households where some peak-hour heating is unavoidable.
21 hours of below-cap electricity: what that means in practice
The 21-hour coverage figure (8 super off-peak + 13 off-peak) is the tariff's defining characteristic. For a heat pump using 6,500 kWh/year:
- If 70% of consumption falls in off-peak or super off-peak hours (likely even without active scheduling)
- Effective blended rate ≈ 0.3×33.3 + 0.5×26.3 + 0.2×8.0 ≈ ~22p/kWh
- Annual cost ≈ £1,430 — vs £1,697 on the standard cap
For an active user who concentrates hot water in the super off-peak and avoids the peak window, the effective rate is lower still.
Is E.ON Next Pumped right for your home?
Next Pumped suits households that want meaningful savings without tight scheduling — the 21-hour below-cap structure means consumption naturally lands in cheaper bands for most of the day. It's particularly well suited to households where the heat pump runs during the day and reliable peak avoidance is difficult.
