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.
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
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.
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
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.
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.
