Our verdict on each
Enel
Enel suits Italian households that want a no-strings electricity plan and a single bill covering gas as well, and its €0 exit fee ranks at 1 of 29. The weaker measure is the standing charge, which places 7 of 16.
Eon Next
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
Enel
Pros
- Exit fee of €0 puts Enel at 1 of 29 on leaving early, so switching the energy plan carries no charge at all.
- Unit rate of €0.11 ranks 3 of 23, which keeps the cost of each unit low against the suppliers compared here.
- Tariff types run fixed and variable with fuels covering electricity and gas, so a household can take light and gas from a single supplier on one account.
Cons
- Standing charge of €12 places Enel at 7 of 16, so a light user pays more of the bill through the fixed charge.
- Tariff types are limited to fixed and variable, so anyone after a dynamic or green option can compare Powerpeers, which lists dynamic, fixed and variable.
- Fuels cover electricity and gas and the fixed and variable pairing carries no prepayment or electric vehicle option, unlike Electricity Ratings at fixed, ev and time of use.
Eon Next
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.
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.
Who each suits
Enel
Who it suits
- Italian households on IT who want light and gas from a single supplier
- Renters or movers who would rather leave a plan without an exit fee of €0
- Heavy users of electricity who gain more from a unit rate of €0.11 than from a low standing charge
Who should look elsewhere
- Households wanting a time-of-use or electric vehicle tariff, which Endesa offers through fixed, time of use and ev
- Buyers who want a dynamic or green option, which Powerpeers lists at dynamic, fixed and variable
- Anyone comparing only on tariff variety, since Electricity Ratings spans fixed, ev and time of use against the fixed and variable listed here
Eon Next
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.

Questions about each
Enel
What does Enel charge to leave an energy plan early?+
The exit fee on Enel's energy plans is €0, so leaving before a term ends costs nothing on the light and gas side. That is unusual among the suppliers compared here, and it matters most to renters and to anyone who expects to move during a term. Broadband from the same company runs under its own separate terms.
How do the unit rate and the standing charge work together?+
The unit rate is €0.11 and the standing charge is €12. The rate applies to each unit of energy consumed, while the standing charge is a fixed cost added whatever the usage. A household using a lot of energy gains more from a low rate, and a light user is more exposed to the standing charge, so both figures matter.
Eon Next
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.
