Pros and cons
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.
Stadtwerke Münster
Pros
- The green tariff is 100% renewable, backed by certificates.
- Tariff choice is broader than Endesa, whose list runs fixed, time of use and ev, with dynamic and variable options added here.
- Full fibre broadband to 1,000 Mbps download and 75 to 300 Mbps upload, with the entry plan priced from €37.99 a month.
Cons
- Support runs on help centre only, with no phone line or live chat listed.
- Unit rate ranks 16 of 23 on the comparison page, so unit price is the weaker part of the offer.
- A smart meter is required, which rules out households needing one installed before they can move.
Who each suits
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).
Stadtwerke Münster
Who it suits
- Households in Münster wanting renewable electricity and full fibre from one supplier.
- People on a dynamic or time-of-use tariff who are happy to have a smart meter in place.
- Customers who prefer a long-established municipal company to the widest tariff list.
Who should look elsewhere
- Anyone after an electric vehicle tariff, since that sits in Endesa's fixed, time of use and ev and not in this range.
- Households wanting phone or chat support, since support runs on help centre only.
- Shoppers who want a longer contract than 12 and 24, or a broader dynamic and variable mix, which Powerpeers lists as dynamic, fixed and variable.

Questions about each
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.
Stadtwerke Münster
What does electricity cost on the green tariff?+
Unit rates run €0.30 to €0.31 on the green tariff, with a standing charge of €14.97 on top. The unit rate ranks 16 of 23 on the comparison page, so the cost of the energy itself, rather than the standing charge, is where this supplier sits higher.
Does the price change when the contract renews?+
The same price holds from the opening month to the last under Same price from first to last contract month, so there is no introductory rate that later disappears. Fixed terms run 12 and 24, which is how long that price is locked for before the next decision point.
