Our verdict

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

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.
  • Fibre broadband sold alongside the energy bill, with 2,500 Mbps download, 1,000 Mbps upload and a Modem Wi-Fi 7 included.
  • A customer base of 11,000,000 and a presence in Italy, FR and ES markets, so the brand is not tied to a single market.

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.
  • Tariff choice is narrower than Powerpeers, which lists dynamic, fixed and variable, or Endesa at fixed, time of use and ev.

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.

Plans and prices

The energy price splits into a usage part and a standing part. The unit rate is €0.17 and applies to what you consume, while the standing charge of €144 applies whether you use much or little. For a low-usage home the standing charge does more damage to the bill than the rate, so a household comparison should start there rather than with the headline rate. The exit fee is €0, and that is the number worth a closer look: a fixed deal can be left without a penalty charge on the final bill, so a cheaper tariff elsewhere does not have to be tolerated for the rest of the term. Flexibility of that sort gets under-rated next to a small saving on the unit rate, because the saving recurs every month while the flexibility only pays out if you actually move.

Core features

The green claim is specific, which is more than most. The tariff is listed at 100% renewable, and the basis is certificates rather than own generation. That is a narrower statement than a supplier running its own wind and solar, and it is the sort of distinction worth keeping in mind: a certificate-backed mix is a way of buying the output, not a picture of the generation fleet. Scale is the other point. The supplier reports 11,000,000 customers, and a base of that size generally comes with an established service operation rather than a small office handling everything. Neither fact tells you how quickly a specific query gets answered, and neither changes what you pay. Read them as separate signals: the share describes what the electricity is, the customer count describes how much organisation stands behind the account.

How it compares on our data

The ranked data puts this supplier near the front on exit fees and in the middle on price. Exit fee ranks 1 of 29 brands, and that is the cleanest signal in the set: leaving costs nothing on the energy side. Standing charge comes out at 16 of 16, a weaker placing, and the unit rate at 12 of 23. Put together, this is a supplier that is easy to leave and unremarkable on price, so the argument for it rests on flexibility and green content rather than on the rate alone. For a household that expects to stay put and decide purely on price per unit, that ordering is worth checking before switching.

The company behind it

The contract is with Eni Plenitude SpA Societa Benefit, headquartered in Italy, and the business dates from 2022. That is a recent outfit operating under a large group name rather than a long-established independent, which matters for anyone weighing how much history sits behind the brand. Support runs on phone, chat and help centre, which covers the routes a household is most likely to reach for, and none of them needs a branch appointment. Between the entity name and the channel list, reaching this supplier and checking who is liable should both be straightforward. What the list does not tell you is how fast a reply comes, so treat it as access rather than service quality.

Frequently asked questions

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.

Can I get a fixed rate, and how long does it lock me in?+

Fixed terms run for 24 months on the energy tariff, and the listed tariff types are fixed and variable, so a household can choose rate certainty or follow the market. Leaving early costs no penalty, so the commitment worth thinking about is the rate being held only for the term rather than any exit charge.

Is the electricity renewable?+

The tariff carries a renewable share of 100%, and the basis is certificates rather than own generation. That is a specific claim about how the mix is certified, which says more than a vague green label but does not tell you the supplier runs its own generation. Buyers who care about owned generation should ask about that separately.

Can I get fibre broadband with my energy account?+

Yes, the fibre plans are sold in versions for existing energy customers, for new customers taking the bundle, and for broadband-only new customers. The versions tied to an energy contract sit at the entry rate of €19.90 and the broadband-only plan at €25.90. The connection is fibre on fttp and fttc, with 2,500 Mbps download and 1,000 Mbps upload.

What does the broadband cost to set up, and am I tied in?+

The setup fee is €39 and the broadband term is 1 months, so the line can be left without a long commitment. For scale, the median setup fee across the plans listed here is €0. A Modem Wi-Fi 7 included comes as part of the plan rather than as a separate purchase, which is worth knowing before comparing hardware bundles.

Where does Eni Plenitude sell?+

The business is headquartered in Italy and operates in Italy, FR and ES. The energy tariff itself is sold in Italy, so anyone outside that market would be looking at a different product. A presence across several European markets is a plus if you travel, but it does not mean the same tariff terms apply in each one.

How do I reach support, and who is my contract with?+

Support runs on phone, chat and help centre, which covers phone, chat and a help centre without needing a branch appointment. The contract is with Eni Plenitude SpA Societa Benefit, a company that has operated since 2022 and reports 11,000,000 customers across its markets. The channel list says nothing about response times, so treat it as access rather than speed.
