Ofcom has released its latest telecoms and pay-TV complaints data for the fourth quarter of 2025, highlighting significant trends in customer dissatisfaction across broadband, landline, and mobile services.
Broadband Providers Under Fire
According to the report, TalkTalk and Vodafone were the most complained-about broadband providers. Vodafone saw an increase in complaints compared to the previous quarter, while TalkTalk's figures remained static. On the other end of the spectrum, Plusnet and Virgin Media were the least complained-about broadband providers.
Landline and Mobile Complaints
In the landline category, BT, EE, NOW Broadband, Plusnet, and TalkTalk generated the most complaints. BT, EE, and Plusnet remained static, NOW Broadband saw an increase, and TalkTalk experienced a decrease. Utility Warehouse was the least complained-about landline provider.
For mobile services, O2 received the most complaints, primarily due to contract-related issues. EE, Tesco Mobile, and Three were the least complained-about mobile providers.
Ofcom's Response
Cristina Luna-Esteban, Ofcom’s Director of Consumers and Retail Markets, commented: “It is disappointing to see an increase in customer complaints during this quarter, especially following a sustained period of decreases. However, a main driver appears to be unexpected mid-contract price rise announcements for some mobile customers in autumn 2025. We will continue to monitor the market, including future complaints figures, for any indication of ongoing customer dissatisfaction.”
Tesco Mobile's Statement
Laura Joseph, Chief Customer Officer at Tesco Mobile, said: “We’re incredibly proud once again to be recognised as one of Ofcom’s least complained-about mobile networks, and as the leading MVNO in the latest report. Throughout 2025, our consistent performance reflects a clear focus on putting customers at the heart of everything we do. This recognition matters because it reflects the trust our customers place in us every day. We continue to listen carefully to feedback and use it to improve, so we can deliver simple, reliable service that families can depend on.”
