EE, TalkTalk and Vodafone have been identified as the UK's most complained-about broadband providers, according to the latest data from communications regulator Ofcom. The figures, covering the third quarter of 2025, show that overall complaint numbers remained stable compared to the previous quarter.
Each of these three providers recorded 10 complaints per 100,000 customers. While EE's complaint levels stayed similar, TalkTalk and Vodafone saw increases. In contrast, Plusnet, owned by BT, received the fewest broadband complaints.
TalkTalk also topped the list for landline complaints, with a quarter-on-quarter rise. In the mobile sector, O2, Sky Mobile and Three attracted the most complaints. O2 and Sky Mobile customers primarily complained about how their complaints were handled, while Three's issues were mainly related to faults, services and getting connected.
EE, Tesco Mobile, Vodafone and iD Mobile generated the fewest complaints for pay-monthly mobile services. For pay-TV, EE received the most complaints, while Sky and TalkTalk had the fewest.
Ernest Doku, broadband and mobiles expert at Uswitch, commented: “The watchdog said it compiled and published the figures to help consumers see how their providers performed in relation to others, and to help them choose a new provider if they were thinking of switching. Patience for poor service is wearing thin. While it is positive to see overall complaint volumes across broadband, mobile, and pay-TV remain steady, the lack of improvement across the industry is a concern for households facing rising bills.”
