Pros and cons
Engie 2026
Pros
- The exit fee is €0, so a fixed term can be ended early with nothing to pay.
- Both fuels are available, electricity and gas, so gas and electricity can sit on one account.
- Tariff choice covers fixed, variable and time of use, including a time-of-use option for households that shift usage through the day.
Cons
- The standing charge of €78 ranks 14 of 16 brands, so the fixed part of every bill is the weak spot.
- The unit rate of €0.14 to €0.16 ranks 8 of 23 brands, which is mid-field rather than a price-led option.
- Coverage is Italy only, so anyone living outside that market has no reason to shortlist it.
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
Engie 2026
Who it suits
- Households in Italy that want electricity and gas on one account, since electricity and gas lists both.
- Anyone who may move supplier before a term ends, because the exit fee is €0.
- Households that shift usage across the day and want a time-of-use option listed in fixed, variable and time of use.
Who should look elsewhere
- Buyers chasing a dynamic tariff: Powerpeers lists dynamic, fixed and variable, which includes dynamic pricing and is not among fixed, variable and time of use.
- Electric vehicle tariff shoppers: Endesa lists fixed, time of use and ev with an EV option, and Electricity Ratings lists fixed, ev and time of use with EV and prepay.
- Households outside the covered market, where coverage of Italy makes the supplier irrelevant.
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
Engie 2026
What does energy cost on an Engie 2026 tariff?+
The unit rate is €0.14 to €0.16 and the standing charge is €78 for the tariff shown. Those two figures drive the bill: the unit rate covers the energy consumed, while the standing charge applies whatever the usage. On the unit rate comparison Engie 2026 sits at 8 of 23.
Is there an exit fee for leaving early?+
No. The exit fee is €0, so ending a fixed term early costs nothing at all. Engie 2026 ranks 1 of 29 brands on that measure, the strongest position among the metrics tracked here, which makes the longer fixed terms far easier to commit to.
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.
