The One Gas + OKGas Heater tariff provide you with a review of the installations to mainly prevent possible gas leaks that would affect the safety of the property's inhabitants in addition to increasing energy consumption and bills.

Endesa's inspection services are preventive visits to check the condition, safety and proper functioning of the gas and heater installations, pursuant to the provisions of the legal and technical regulations.

During a technical inspection, the following is carried out:

  • A check of all the installation's components (taps, fastenings, pipes, nozzles, ventilation, etc.).
  • Necessary adjustments to guarantee the safety of the installation and, to the greatest extent possible, reduce the gas consumption, number of breakdowns or future failures of the equipment.
  • Checking for leaks in the gas installation.
  • Checking and adjusting the operation of equipment.
  • Combustion analysis and submission of the result.
  • Mandatory Periodic Inspection of the gas installation.
  • Mandatory Regulations for Thermal Installations in Buildings (in Spanish, RITE) service.
  • It turns itself off and on while it's running.
  • The flame is low and yellow.
  • It works properly for a few minutes and then turns off and does not turn on.
  • It doesn't heat the water properly.
  • When it is working, it has small water leaks.

The price may be updated on 1 January each year by the value of the actual CPI (last General Year-on-Year Consumer Price Index officially published at the time of the update), as well as for variations in the current regulated components that apply to electricity and gas supplies, and with possible new changes that may be approved by regulation.

In case of updating with the value of the CPI, the year-on-year CPI for November, published on the website of the National Institute of Statistics (https://www.ine.es/) will be used. The update will be made by adding to the previous prices the result of multiplying the CPI by those prices. For more information, the year-on-year CPI for November 2021 was 5,5%, the year-on-year CPI for November 2020 was -0.8% and the year-on-year CPI for November 2019 was 0.4%.

Any changes in the regulated components applicable in the contract (upwards or downwards) will be transferred to the customer. These modifications are regulated, they are totally beyond Endesa's control and apply equally throughout Spain and to all companies.

The price may also be reviewed one year after contracting. If there were any changes, we would let you know one month in advance. Always remember that at any time you can terminate the contract or contract another tariff from Endesa or any other company without penalty.

With the One Gas tariff there is no commitment to duration: You can cancel whenever you want, without penalty. However, the One Gas Tariff contract has a duration of one year, automatically renewable.
