Our verdict

Eon Next suits households that want several tariff styles and a solar or charger-friendly setup, and it holds a reference annual cost of £166. The trade-off is the exit fee of £25, which matters if you might move supplier early, so compare the term length before you join.

Pros and cons

Pros

  • Tariff types run to variable, fixed and tracker, a wider spread than Endesa, which lists fixed, time of use and ev.
  • Fuels cover electricity and gas, so electricity and gas can sit on the same account.
  • Renewable electricity accounts for 27.3% and solar households are paid an export rate of £0.15.
  • Electric vehicle owners get an off-peak rate of £0.085 for charging.
  • Fixed terms run 12 and 24 months, so there is an end date to plan around.

Cons

  • Leaving early costs an exit fee of £25, and Eon Next ranks 21 of 29 brands on that measure.
  • The unit rate of £0.32 sits at 20 of 23, so the headline rate is not at the front of the table.
  • Support runs on email, phone and help centre only, with no live chat channel listed.
  • A smart meter is required, which rules out households that would rather keep manual readings.

Who it suits

  • Households served in GB with rooftop solar or a home charger, who can use the export rate of £0.15 and an off-peak rate of £0.085.
  • People who want tariff types to include variable, fixed and tracker so they can change style of plan later.
  • Anyone comfortable with a reference annual cost of £166 alongside an exit fee of £25.

Who should look elsewhere

  • Shoppers after a green tariff, since Electricity Ratings lists fixed, ev and time of use and Eon Next does not.
  • Households that want a prepay option, since Eon Next covers variable, fixed and tracker while Endesa offers fixed, time of use and ev.
  • Buyers who expect a cheap exit, since leaving early costs £25 and the brand ranks 21 of 29 on that measure.

Pricing

Two figures do most of the work for readers weighing price now against price later. Next Optimise is listed at a reference annual cost of £166, and Next Drive carries a unit rate of £0.32 with an exit fee of £25. Electric vehicle owners can charge at an off-peak rate of £0.085, the part of the tariff that rewards shifting usage to overnight hours.

What it does well

Renewable sources account for 27.3% of the electricity supplied, and solar households are paid an export rate of £0.15 for power sent back to the grid. A smart meter is required, so readings arrive without manual estimates and usage-based pricing works as advertised. Behind the brand sits a base of 5,000,000 customers.

Where it sits among rivals

The rankings split depending on what you measure. On reference annual cost, Eon Next sits at 1 of 4 brands, which is the strong line. On unit rate it is 20 of 23, and on exit fee 21 of 29. Annual cost is where this supplier tops the table, while the other two measures place it further down.

Who runs it

The supplier is E.ON Next Energy Limited, headquartered in the United Kingdom. Support runs on email, phone and help centre, giving households both direct contact and self-service routes. The legal name is the one to quote if you need to raise a billing query.

Frequently asked questions

What does Eon Next cost on a typical year of usage?+

The Next Optimise tariff is listed at a reference annual cost of £166. That is the headline figure to set against other suppliers, and on this comparison Eon Next sits at 1 of 4 brands ranked on that measure. Your own bill will move with your usage.

Is there an exit fee if I leave Eon Next early?+

Yes, leaving early costs £25. On that measure the brand ranks 21 of 29 brands in the comparison, so the fee is worth setting against the headline price before you commit to a term.

Do I need a smart meter to be on an Eon Next plan?+

A smart meter is required for the plans listed here. That is the setup that lets readings come in automatically and keeps usage-based pricing, including the export rate of £0.15, accurate across a billing period.

What do I get paid for exporting my own solar electricity?+

Next Optimise pays an export rate of £0.15 for electricity sent back to the grid, so rooftop solar households earn rather than simply offset. Renewable sources sit at 27.3% of the electricity supplied, which sets the wider environmental context.

Which types of tariff can I choose from?+

The listed range covers variable, fixed and tracker. That is wider than Endesa, which offers fixed, time of use and ev, and it includes dynamic pricing for anyone willing to move usage to cheaper windows.

Where does Eon Next operate?+

Eon Next supplies electricity and gas and serves GB, run from E.ON Next Energy Limited based in the United Kingdom. It serves a single market rather than several, which keeps the range focused on what that market needs.

How do I get help from Eon Next?+

Support runs on email, phone and help centre, which covers phone and email alongside the help centre and community forum. There is no live chat channel in that list, so instant messaging help is not part of the offer.

Do Eon Next fixed plans run for a set period?+

Fixed terms run 12 and 24 months, so there is a clear end date instead of a plan that rolls on. Alongside those, Eon Next lists variable, tracker, EV and dynamic options for households who want to change style later.
