Our verdict on each
Ecotricity
Ecotricity suits households in Britain that want a full renewable supply, where the listed basis is own generation. The supply runs at 100% renewable, electricity and gas sit on the same account, and a smart meter is not required, so metering does not hold you back.
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
Ecotricity
Pros
- Renewable supply of 100%, with the basis listed as own generation rather than certificates.
- The exit fee is £0, and Ecotricity ranks 1 on that measure among the 29 brands compared.
- Electricity and gas on the same account, since fuels listed are electricity and gas.
Cons
- Tariffs are variable, green and prepay, so there is no fixed or dynamic price, unlike Powerpeers with dynamic, fixed and variable.
- Electric vehicle and time of use tariffs are not among its tariff types (variable, green and prepay), while Electricity Ratings lists fixed, ev and time of use.
- Coverage is GB with regions served listed as Britain, so it is a single market choice.
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
Ecotricity
Who it suits
- Households in Britain that want a wholly renewable supply rather than a partly green one.
- Dual fuel households, since fuels listed are electricity and gas and both sit on the same account.
- Prepay customers, since variable, green and prepay includes a prepay tariff.
Who should look elsewhere
- Powerpeers, if you want a fixed or dynamic price, since dynamic, fixed and variable lists both.
- Electricity Ratings, if an electric vehicle tariff matters, as fixed, ev and time of use includes one and it is not among variable, green and prepay.
- Endesa, if a fixed rate with time of use windows is the deciding factor, since fixed, time of use and ev lists that shape.
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
Ecotricity
Is Ecotricity's electricity fully renewable?+
Yes, the supply runs at 100% renewable, and the basis listed is own generation rather than certificates. That distinction matters if you are choosing a green tariff for the provenance of the power as much as for the label on the bill.
What does Ecotricity pay for electricity I export from my solar panels?+
The smart export tariff pays £0.12 for each unit sent back to the grid. That is the figure to weigh if you have rooftop solar or a battery, because exported power that earns nothing weakens the case for generating at all.
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.
