Complaints about broadband, landline, mobile and pay-TV services in the UK remained broadly unchanged in the third quarter of 2025, according to the latest figures from communications regulator Ofcom.
The regulator said the volume of complaints it received between July and September 2025 was similar to the previous quarter across all four services it monitors: fixed broadband, landline, pay-monthly mobile and pay-TV.
Ofcom publishes complaint rates per 100,000 customers to allow comparisons between providers relative to the size of their customer bases.
In fixed broadband, EE, TalkTalk and Vodafone generated the highest number of complaints during the quarter. EE’s complaint levels were unchanged from the previous quarter, while both TalkTalk and Vodafone saw increases.
Plusnet recorded the lowest number of broadband complaints.
TalkTalk was the most complained about provider for landline services, with complaints increasing compared with the previous quarter. Utility Warehouse generated the fewest landline complaints.
In the pay-monthly mobile market, the highest complaint levels were recorded by O2, Sky Mobile and Three. Complaints about O2 and Sky Mobile were mainly related to the handling of complaints, while Three customers most frequently reported faults and service provisioning issues.
The lowest complaint volumes in the mobile sector were recorded by EE, Tesco Mobile, Vodafone and iD Mobile.
EE generated the most complaints in the pay-TV sector, while Sky and TalkTalk recorded the fewest.
Ofcom noted that some providers’ results are considered statistically comparable where the difference in complaints per 100,000 customers is less than one. In fixed broadband, this includes Sky and Virgin Media, Virgin Media and the industry average, and EE, Vodafone and TalkTalk.
Despite quarter-on-quarter stability, a year-on-year comparison showed improvement across the sector, with complaint levels falling across fixed broadband, landline, pay-monthly mobile and pay-TV services.
The data forms part of Ofcom’s ongoing monitoring of consumer satisfaction across telecoms and television services in the UK.
