EE has emerged as Britain’s most complained-about provider across broadband, landline, and pay-TV services between April and June, according to the latest figures from Ofcom.
This marks the first instance since late 2023 that a single provider has been the worst performer across three distinct services.
In contrast, Plusnet maintained its position as the least complained-about fixed broadband provider for the second consecutive quarter.
Interestingly, EE’s mobile division performed strongly, ranking among the least complained-about alongside Tesco Mobile and Vodafone, with its complaint numbers either falling or remaining stable compared to the previous quarter.
Three UK, which recently merged with Vodafone in a £16.5 billion deal, received the most mobile complaints.
However, Ofcom noted that the gap between providers was minimal, making it difficult to "meaningfully differentiate" between them.
Ofcom regularly publishes quarterly complaint figures for the UK’s primary landline, mobile, broadband, and pay-TV providers. Overall, the watchdog reported a decline in complaint numbers since the first three months of 2025, reaching their lowest or joint-lowest level on record.
Complaints about fixed broadband, landline, and pay-TV dropped, although it saw grievances about pay-monthly mobile services remain the same.
It said EE’s customers across broadband, landline and pay-TV mainly complained about faults, service quality and getting connected, as well as concerns over how grievances are handled and the service they receive when changing provider.
Across landline, Utility Warehouse was the least complained about once again, maintaining this now for 18 months running, while TalkTalk received the fewest complaints for pay-TV services.
Cristina Luna-Esteban, Ofcom’s director of consumers and retail markets, said: “We’re pleased to see the continued reductions in complaints that we’ve received.
“In fact, complaints across all services are at the lowest or joint lowest levels we’ve ever seen.
“This is a significant benchmark, and we hope this positive momentum continues, for the benefit of customers now and in the future.”
An EE spokeswoman said: “EE remains focused on consistently providing excellent customer service.
“Each year we invest millions of pounds into new technology and training to enable our guides to offer the best possible customer experience.
“With more customers than ever joining EE Broadband, they are more likely to interact with us as they adjust to a new service which can in some cases increase the likelihood of a complaint, however, we’re laser-focused on ensuring their experience is smooth, hassle-free, and complaint-free.”
Rob Orr, Virgin Media O2’s chief operating officer, said: “Today’s Ofcom data is further proof that our laser focus on improving customer service is paying off, with complaints down by more than 50 per cent year-on-year, and by almost a third compared with the previous quarter.
“We’re investing heavily across the business to simplify our systems and processes, upskill our agents and roll out new technology that helps them support our customers when they get in touch.”
