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.
Octopus Energy
Pros
- Exit fee is €0, so a fixed term can be left early without a penalty
- Green tariff is backed by 100% renewable supply on a certificates basis
- Tariff choice covers fixed, variable and green on both electricity and gas
Cons
- Fixed terms run 12 months and then need a renewal decision, since no separate renewal price is set out
- Unit rate of €0.17 sits mid-field, so it does not undercut every rival on usage
- Tariff list covers fixed, variable and green only, with no time of use or electric vehicle option as listed
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.
Octopus Energy
Who it suits
- Italian households in IT who want to switch supplier without paying to leave
- Households that want a green tariff on a certificates basis at 100% renewable supply
- People who prefer fixed pricing but want an exit fee of €0 behind it
Who should look elsewhere
- Households wanting an electric vehicle or time of use tariff, since fixed, variable and green does not list them
- Anyone outside IT, where the supplier does not operate
- Households chasing the lowest unit rate, where €0.17 is only mid-field

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.
Octopus Energy
What does Octopus Energy cost to leave?+
Leaving costs €0. That is the figure that separates this supplier from many fixed term offers, where an early exit can be chargeable. A household that expects its circumstances to change can hold the tariff without budgeting a penalty for the move.
Which markets does Octopus Energy serve?+
Octopus Energy sells in IT only, so the tariffs and support described here apply there. Anyone outside that market will not find these offers, and would need a supplier operating in their own country.
