Pros and cons
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.
PremiumSIM
Pros
- Sim only plans start at €6.99, below the €9.30 median across listed brands
- Terms run 1 and 24, so a rolling option sits next to a longer commitment
- 5G, eSIM and wifi calling are all available, which is what most listed mobile plans carry
Cons
- The fibre line carries a setup fee of €49.99 and post contract pricing of €44.99
- As an mvno, the provider sets its own tariffs on another carrier's network and stays inside DE
- Uploads of 5.8 to 40 Mbps sit below downloads of 1,000 Mbps, which matters for sending large files
Who each suits

Questions about each
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.
PremiumSIM
What does the cheapest PremiumSIM mobile plan cost?+
The starting price across the range is €6.99, set on a small allnet plan. A second reference plan adds a much larger data allowance at a higher monthly cost, and no unlimited plan appears among the reference plan prices. Heavy data users would pay for the larger tier from the first bill.
How long is the contract?+
Plan contract months run 1 and 24, so a short rolling arrangement sits alongside a longer commitment. Billing is offered as contract or rolling, which lets you match the term to how long you expect to keep the line. Households that expect to move soon should read the longer term carefully.
