Pros and cons

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.
  • Tariffs run fixed, time of use and dynamic (fixed, time of use and dynamic), so you can pick how your price moves.
  • Support runs on email, phone and help centre, so written, spoken and self service help are all available.

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.
  • Live chat is not part of email, phone and help centre, so quick answers may have to wait on email or the phone.

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).

How it compares on our data

niba ranks 1 of 29 brands on exit fee and 1 of 16 on standing charge. Both of those columns are where it puts most households ahead of the field. The unit rate is the softer spot, at 5 of 23, so heavy users have more reason to shop around before they commit.

Plans and prices

Prices split into a unit rate of €0.12 for the energy you use and a standing charge of €0.091 for keeping the account open. Leaving costs nothing, because the exit fee is €0. That split favours light users, who pay less in the fixed part, and it keeps a switch cheap for everyone else too.

Core features

The whole supply is renewable at 100%, so every unit is covered rather than a slice of the bill. Panels on the roof suit the model, because an export rate of €0.06 pays you for the energy pushed back out. Covering both sides of the meter works well for homes that generate as well as consume.

The company behind it

The trading name is FASTLIGHT, S.L.U, headquartered in Spain. Support runs on email, phone and help centre, giving you email, phone and help centre routes rather than branch visits. Contracts, tariffs and support all sit in that same home market, so the terms are written for the country you live in.

Frequently asked questions

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.

Is the electricity renewable?+

Yes. Renewable supply is 100%, covering the whole plan rather than part of it. If you have rooftop panels, the export rate of €0.06 means you are paid for the electricity you send back out, which makes the tariff easier to justify for a generating home.

Where can I sign up?+

niba sells in Spain, and the regions served are listed as Iberian Peninsula. It is a single market operation, with its headquarters in Spain. If your supply sits outside Spain, none of these tariffs apply to you and you would need a local supplier.

Which tariffs can I choose?+

The list runs fixed, time of use and dynamic, given as fixed, time of use and dynamic. A fixed price holds steady, time of use follows a daily schedule, and dynamic follows the market. Powerpeers adds a variable option and Electricity Ratings adds prepay, so niba suits people content with these three.

How do I get help?+

Support runs on email, phone and help centre, so you can email, call or read the help centre. Live chat is not on that list, so quick questions may sit until someone replies by email or answers the phone. A call is the quicker route for anything urgent.

Can I take electricity and gas together?+

Yes. The fuels listed are electricity and gas, so both can sit on a single account. Keeping them together means a single support route and a single fixed part to judge, instead of two separate relationships to manage and a fixed part split across suppliers.

Does niba suit people who switch often?+

It does, because the exit fee is €0 and the fixed term runs 12 months. A short term with nothing to pay on the way out lets a household chase the market without penalty. niba ranks 1 of 29 brands on exit fee for exactly that reason.
