Should You Fix With E.ON Next?

Next Flex Variable Tariff

  • Pros: No exit fees, flexible, follows price cap (protection from excessive rises), April 2026 will see £130-150 reduction
  • Cons: Prices change quarterly, no long-term certainty, currently £208 more expensive than Next Fixed 16m
  • Current rate: £1,758/year (Jan-Mar 2026)
  • Who it's for: People who want maximum flexibility or expect prices to drop significantly

Next Fixed 16m / 18m Tariffs

  • Pros: £208/year cheaper than price cap, guaranteed rates for 16-18 months, budget certainty, currently cheapest fixed deals from major suppliers
  • Cons: £50 per fuel exit fee (£100 total for dual fuel), will miss April 2026 price drop on variable tariff
  • Current rates: £1,550 (16m) and £1,552 (18m)
  • Who it's for: People wanting price certainty and willing to commit for over a year

💡 January 2026 Recommendation

E.ON Next Fixed 16m is excellent value at £1,550 - it's the cheapest fixed tariff from major suppliers and saves £208/year vs price cap.

However, consider timing:

  • Fix now if: You want guaranteed savings and budget certainty for 16 months
  • Wait until April if: You're on variable and want to benefit from the £130-150 levy removal first, then reassess fixed deals

Exit fee math: £100 total exit fee (£50 electric + £50 gas) vs £208 annual saving = payback in 6 months. Worth fixing if you'll stay at least 6 months.

Frequently Asked Questions

How accurate is this E.ON bill calculator? ▼

This calculator uses official Ofgem price cap rates for E.ON Next's standard variable tariff (Next Flex) and published rates for fixed tariffs. Estimates are accurate within 1-3% for typical customers.

Minor variations occur due to:

  • Billing period length (28-31 days per month)
  • Fixed tariff rates may change slightly by region

Will E.ON Next bills go up or down in 2026? ▼

January 2026: Tiny 0.2% increase from £1,755 to £1,758 (just £3/year).

April 2026: Expected to fall by £130-150 when government removes environmental levies from electricity bills. This is confirmed policy.
