Pros and cons
Endesa
Pros
- Exit fee of €0 means a fixed term can be ended early without a charge, which is unusual in this group.
- Unit rate of €0.12 and standing charge of €2.85 sit at the competitive end of the suppliers listed here.
- A tethered home charger costs €1,099 with installation included, gives power of 7.4 to 22 kW and carries a warranty of 3 years.
Cons
- Tariff choice is narrower than some rivals: fixed, time of use and ev covers fixed, time-of-use and EV, while Powerpeers lists dynamic, fixed and variable.
- A green tariff does not appear in fixed, time of use and ev, though Electricity Ratings includes fixed, ev and time of use.
- Coverage is limited to Spain, Canarias and Baleares, so households in other markets need a different supplier.
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
Endesa
Who it suits
- Households in Spain, Canarias or Baleares that want electricity and gas from one supplier with an exit fee of €0.
- EV owners who want a tethered charger fitted at home and linked to the electricity tariff.
- Customers who expect phone help, since email, chat and phone includes phone and chat alongside email.
Who should look elsewhere
- Powerpeers readers who want a dynamic or variable tariff, since dynamic, fixed and variable lists both and fixed, time of use and ev does not.
- Anyone set on a green tariff, which Electricity Ratings offers in fixed, ev and time of use but Endesa does not list.
- Households outside Spain, Canarias and Baleares, and readers who prefer the fixed-only setup of Base Power Company in fixed.
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
Endesa
Does it cost anything to leave an Endesa contract early?+
The exit fee listed for the Conecta de Endesa plan is €0, so ending a fixed term early carries no charge. That stands out among the suppliers in this comparison, several of which price a fee for switching. It makes Endesa easier to move away from if wholesale prices move against you later.
What does a unit of electricity cost from Endesa?+
The unit rate on Conecta de Endesa is €0.12, with a standing charge of €2.85 added to the bill. In this comparison the unit rate ranks 6 of 23 and the standing charge 3 of 16, putting both figures near the competitive end of the group.
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.
