Pros and cons
Ecotricity
Pros
- Renewable supply of 100%, with the basis listed as own generation rather than certificates.
- The exit fee is £0, and Ecotricity ranks 1 on that measure among the 29 brands compared.
- Electricity and gas on the same account, since fuels listed are electricity and gas.
Cons
- Tariffs are variable, green and prepay, so there is no fixed or dynamic price, unlike Powerpeers with dynamic, fixed and variable.
- Electric vehicle and time of use tariffs are not among its tariff types (variable, green and prepay), while Electricity Ratings lists fixed, ev and time of use.
- Coverage is GB with regions served listed as Britain, so it is a single market choice.
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.
Who each suits
Ecotricity
Who it suits
- Households in Britain that want a wholly renewable supply rather than a partly green one.
- Dual fuel households, since fuels listed are electricity and gas and both sit on the same account.
- Prepay customers, since variable, green and prepay includes a prepay tariff.
Who should look elsewhere
- Powerpeers, if you want a fixed or dynamic price, since dynamic, fixed and variable lists both.
- Electricity Ratings, if an electric vehicle tariff matters, as fixed, ev and time of use includes one and it is not among variable, green and prepay.
- Endesa, if a fixed rate with time of use windows is the deciding factor, since fixed, time of use and ev lists that shape.
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.

Questions about each
Ecotricity
Is Ecotricity's electricity fully renewable?+
Yes, the supply runs at 100% renewable, and the basis listed is own generation rather than certificates. That distinction matters if you are choosing a green tariff for the provenance of the power as much as for the label on the bill.
What does Ecotricity pay for electricity I export from my solar panels?+
The smart export tariff pays £0.12 for each unit sent back to the grid. That is the figure to weigh if you have rooftop solar or a battery, because exported power that earns nothing weakens the case for generating at all.
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.
