E.ON Next Drive Smart EV Tariff Review 2026
E.ON's smart EV tariff: 8p/kWh whole-home off-peak (00:00–06:00), 1-year fixed, no charger compatibility list, no exit fees. Direct IOG competitor.
4.1 / 5
☆☆☆☆☆
★★★★★
Pros
- 8p/kWh off-peak rate is competitive with IOG and undercuts most other UK smart EV tariffs
- Whole-home off-peak applies — your dishwasher, dryer, and heat pump on a schedule all benefit, not just the EV
- No charger compatibility list — works with ANY home charger or even a 3-pin cable, unlike IOG's restricted list
- Six-hour off-peak window (00:00–06:00) is comfortably long for typical overnight charging on a 7kW unit
- One-year fixed contract — rate locked in regardless of wholesale moves through the term
- No exit fees — switch out if your circumstances change
Cons
- No dynamic bonus-slot system — what you see is what you get; no daytime cheap windows when the grid has surplus renewable capacity
- Day rate (~26p/kWh) is mid-range — households with high daytime usage may pay more on the day side than they save on the EV side
- Fixed-window only — drivers who can't fit charging inside 00:00–06:00 (large batteries, multiple EVs) will run sessions into the peak rate
- Standing charge varies by region and isn't pinned in marketing copy — pull a postcode quote before committing
- 1-year fixed term means you can't capitalise on falling rates mid-term (though no-exit-fee mitigates this)
