BT, EE, TalkTalk and Vodafone were the most complained-about broadband providers in the UK between April and June 2026, according to figures published by Ofcom on 26 October 2026.
The regulator’s quarterly report counts the complaints it receives about the main landline, broadband, mobile and pay-TV providers, measured per 100,000 subscribers. Overall complaints fell compared with the previous quarter. Ofcom says the fall was caused by fewer complaints about pay-TV, while complaints about broadband, landline and mobile stayed the same.
Broadband
Among the four most complained-about broadband providers, BT’s figures were unchanged on the previous quarter, EE’s rose, and TalkTalk’s and Vodafone’s fell. Plusnet, Sky and Virgin Media were the least complained-about broadband providers.
Landline and mobile
Plusnet generated the most landline complaints, up on the previous quarter, and its customers mainly complained about how their complaints were handled. Sky, Utility Warehouse, Virgin Media and Vodafone generated the fewest.
On pay-monthly mobile, O2 and Sky Mobile drew the most complaints. O2’s were mainly about faults, service and getting connected, while Sky Mobile’s were mainly about customers’ experiences of changing provider. EE, Giffgaff, Tesco Mobile, Three, Vodafone and iD Mobile generated the fewest.
Pay-TV
EE and Virgin Media were the most complained-about pay-TV providers and TalkTalk the least. For pay-TV, the main reason customers complained to Ofcom was how providers had handled their complaints. For broadband, landline and mobile, the biggest reasons were faults, service quality and getting services connected.
The wider picture
Ofcom notes that a deal was announced earlier in October for BT Group to acquire TalkTalk Group, after the period these figures cover. It comes as the competition regulator is also examining nexfibre’s planned takeover of the Substantial broadband group. More UK telecoms coverage is in our tech section.
Ofcom cannot resolve individual complaints, but publishes the figures so customers can compare providers. The provider-by-provider rates per 100,000 subscribers are shown in charts on Ofcom’s page rather than in its text.
What to watch next: whether EE’s rise in broadband complaints and Plusnet’s rise in landline complaints carry into the third-quarter figures, and how the BT and TalkTalk deal progresses.
