Our verdict on each
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.
Frontier Communications
Frontier Communications suits households in the US that want top tier fibre speed without a long contract, and it undercuts many rivals on entry price at $29.99. The catch is a setup fee of $100 plus a charge for leaving early on some promotional deals.

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.
Frontier Communications
Pros
- Entry pricing of $29.99 sits in the lower part of our price table, and the reference plans come with no fixed term
- Top download of 7,000 Mbps and upload of 7,000 Mbps put it near the front of the speed table
- A current Wi-Fi router is included, and Whole Home Wi-Fi mesh comes on the gigabit tier and anything faster
Cons
- A setup fee of $100 lands near the expensive end of the setup fees we track
- Some promotional deals add a charge for leaving early, and disconnecting soon after joining means paying back part of the installation cost
- Service is confined to a single market, US, so it is not an option outside the US
Who each suits
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.
Frontier Communications

- Households in the US inside Frontier's fibre footprint, willing to accept a setup fee of $100 for a lower monthly price
- Anyone who needs gigabit speeds for large uploads, remote work backups or shared media
- People who want to leave without a long lock-in, since the reference plans run on rolling monthly terms
Who should look elsewhere
- Households outside the US, since service is confined to a single market, US
- Shoppers who want a cable package rather than pure fibre, since Astound runs cable and fttp
- People hunting for the very lowest entry price, since cheaper options sit below $29.99

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.
Frontier Communications
What is the entry price for Frontier fibre?+
Plans start at $29.99 a month, and the reference tiers step up in speed from there to a multi gigabit option at the top. Every one of them is sold on rolling terms, so the monthly figure is the number to compare against rival quotes. Speeds, not term length, are what separate the tiers here.
Do I have to sign a contract with Frontier?+
No. The reference plans, from the entry tier through to the multi gigabit tier, are all sold without a fixed term, and the listed contract length is a rolling monthly term. That leaves you free to cancel without counting out a period first, which suits anyone who expects to move or switch.
