Gas retailers

If your gas installation is completed and you have the certificate issued by the installer, you can contract the natural gas supply with a retailer. The retailer of your choice will be in charge of sending us your request to sign up for natural gas. There are two contracting options:

  • Contract the supply at a price and under conditions freely agreed with a retailer. On the free market, the companies set the energy price and consumers choose the tariff that best suits them.
  • Sign up for the last resort tariff. The Administration sets the price in this case. . This tariff is available to those consumers connected to gas pipelines whose pressure is lower or equal to 4 bars and whose annual consumption is under 50,000 kWh. There are two last resort tariffs depending on the customer’s annual consumption:
    • TUR.1 for consumption under or equal to 5,000 kWh/year. This consumption range is the standard for a home with a natural gas cooker and/or water heater.
    • TUR.2 for consumption over or equal to 15,000 kWh/year and under 50,000 kWh/year. This consumption range is the standard for a home with natural gas heating.
    • TUR.3 for consumption over 15,000 kWh/year and under or equal to 50,000 kWh/year. This consumption range is the standard for a single-family house with natural gas heating or in small businesses.

The following companies are designated as last resort retailers:

  • 1. Comercializadora regulada, gas & power, S.A.
  • 2. Baser comercializadora de referencia, S.A
  • 3. Energía XXI comercializadora de referencia, S.L.
  • 4. Curenergia comercialización de último recurso, S.A.U

If you’d prefer, you can choose to contract your gas supply at a rate and under conditions you agree upon freely with a retailer.

You can learn about different aspects of the natural gas market on the CNMC’s website under ‘Energy/Consumers/Natural Gas’ or by calling 91 432 96 00.
