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.
Eni Plenitude
Eni Plenitude suits Italian households that want electricity and gas on a single fixed deal with an energy exit fee of €0. The tariff is listed at 100% renewable on a certificate basis, and the fibre broadband sold alongside gives a second reason to stay with one supplier.

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.
Eni Plenitude
Pros
- The €0 exit fee ranks 1 of 29 brands, the clearest advantage in the set here.
- Renewable share of 100% on a certificate basis, so the green claim names how it is certified.
- Electricity and gas on the same account, electricity and gas, with fixed terms of 24 months if you want rate certainty.
Cons
- The €144 standing charge is the weak point, ranking 16 of 16 and sitting above the €14.98 market median.
- The fibre line carries a €39 setup fee, where the median setup fee across the plans listed here is €0.
- Broadband-only new customers pay €25.90 rather than the €19.90 rate offered with an energy contract.
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
Eni Plenitude
Who it suits
- Italian households that want electricity and gas on a single fixed deal with a €0 exit fee.
- Existing energy customers adding fibre, who get the €19.90 entry rate rather than €25.90.
- People who want a support mix of phone, chat and help centre with a phone line in it.
Who should look elsewhere
- Buyers after hourly or dynamic pricing rather than a fixed rate: Powerpeers lists dynamic, fixed and variable.
- Shoppers set on prepay or a separate green choice: Electricity Ratings lists fixed, ev and time of use.
- Households looking for time-of-use or electric vehicle tariffs: Endesa lists fixed, time of use and ev.

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.
Eni Plenitude
Is there an exit fee on the energy contract?+
No penalty charge applies to the energy tariff, where the exit fee is €0. Broadband is treated separately: the fibre line carries a deactivation charge if you cancel within the initial period, and that charge is reduced when you hold an energy contract with the same supplier. Leaving the energy side is simple; leaving the fibre side is not free.
What do I actually pay on the energy side?+
The unit rate is €0.17 and the standing charge is €144, and the standing charge applies whatever the household uses. Low-usage homes feel that fixed part harder, so the same tariff can look different from home to home. Both fuels, electricity and gas, sit on the same contract.
