Internet and mobile telephony were once again the best-rated services by consumers in Spain, according to data from the latest Household Panel of the National Markets and Competition Commission (CNMC), corresponding to the fourth quarter of 2025.
According to the survey, around 70% of users declared themselves satisfied or very satisfied with both mobile internet service and mobile telephony.
For their part, about six out of ten households expressed satisfaction with their electricity and gas supplies, with satisfaction rates of 56.7% and 58.9%, respectively.
The cost of services continued to be the main cause of discontent among Spanish households, both in the energy sector and in that of telecommunications.
In the case of electricity supply, 84.2% of dissatisfied households pointed to price as the main reason, a percentage that rose to 86.5% in the case of natural gas.
The second major factor of dissatisfaction with energy services was the lack of clarity in the bills and in the prices applied, followed by the scarce information about the supply conditions and contractual aspects.
In the telecommunications sector, price also topped the reasons for complaint in most services, although in the case of mobile internet, service quality became the primary reason for dissatisfaction.
User Claims
The CNMC's Household Panel also incorporates data on users who have filed complaints. Thus, the survey indicates that approximately one in ten users registered a complaint related to their fixed broadband service (10.2%). In contrast, the percentage of users who complained about natural gas was approximately half (5.2%).
Regarding the rest of the services, claims in fixed telephony stood at 6.3%; in natural gas, at 5.2%; and in electricity, at 6.1%.
In the field of telecommunications, most claims were mainly due to service quality problems, while in electricity supplies the most common origin of complaints were billing incidents.
