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.
niba
Pros
- An exit fee of €0 means switching costs nothing, which places niba in the no exit fee group.
- Renewable supply of 100% covers the whole plan, and an export rate of €0.06 rewards rooftop solar.
- A standing charge of €0.091 keeps the fixed part of bills small for light users.
Cons
- The unit rate of €0.12 sits above the cheapest tariffs in the comparison, so heavy users pay more for each unit.
- Sales cover ES only, across the Iberian Peninsula, so there is nothing on offer for households elsewhere.
- Endesa and Electricity Ratings both list an electric vehicle tariff, while the niba range is fixed, time of use and dynamic.
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.
niba
Who it suits
- Households in Spain that want to leave a fixed contract without paying an exit fee.
- Homes with rooftop solar that want renewable supply plus an export rate.
- People who want electricity and gas together across fixed, time of use or dynamic pricing.
Who should look elsewhere
- Electricity vehicle drivers: Endesa lists fixed, time of use and electric vehicle tariffs (fixed, time of use and ev), and a charging rate is the point for them.
- Anyone after a variable or prepay choice: Powerpeers lists dynamic, fixed, variable and green (dynamic, fixed and variable).

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.
niba
What does it cost to leave niba?+
Nothing. The exit fee is €0, so you can end the contract without paying to walk away. The fixed term runs 12 months, so the commitment stays short and an earlier switch costs nothing. That makes niba a low risk contract to try first.
How much is the energy itself?+
The unit rate is €0.12 and the standing charge is €0.091. The unit rate moves with how much you consume, while the standing charge is the fixed part you pay regardless. Light users notice the fixed part most, heavy users notice the unit rate most.
