Ofcom says complaints about the UK’s major telecoms and pay-TV providers rose in the final quarter of 2025, the first increase since 2023.
The regulator said the rise was mainly driven by mobile complaints, following mid-contract price rise announcements by some providers, including O2.
Broadband and landline complaints fell during the quarter, while pay-TV complaints were unchanged.
Cristina Luna-Esteban, Ofcom’s director of consumers and retail markets, said it was “disappointing” to see complaints increase after a sustained period of falls, adding that Ofcom would continue to monitor the market for signs of ongoing customer dissatisfaction.
Vodafone and TalkTalk were the most complained-about broadband providers, with 11 complaints per 100,000 and 10 per 100,000 customers respectively, while Plusnet and Virgin Media generated the fewest complaints.
O2 was the most complained-about mobile provider, with customers mainly raising contract-related issues. EE, Tesco Mobile and Three generated the fewest mobile complaints.
For pay-TV, EE received the most complaints, while Sky, TalkTalk and Virgin Media were the least complained-about providers.
