Report: Complaints about broadband, landline, mobile and pay-TV services

Published: 25 January 2024

As the UK’s communications regulator, Ofcom receives complaints from customers about their landline, fixed broadband, pay-monthly mobile and pay-TV services.

To better understand the reasons for dissatisfaction among residential customers in our sectors, we compile that data and determine the number of complaints received by provider and by service. To compare the performance of providers, on a quarterly basis we publish the number of complaints that we received about them relative to the size of their customer bases (i.e. per 100,000 customers).

Overall trends

In the quarter from October to December 2023 (Q4 2023), complaints to Ofcom have remained at similar levels from the previous quarter (Q3 2023: July to September 2023). Complaints about landline, fixed broadband and pay-TV all fell from the previous quarter while mobile pay-monthly remained at similar levels.

  • Virgin Media remained the most complained about broadband, landline and pay-TV provider, although they did see a fall in all of these areas from the previous quarter. Customers’ complaints were again mainly driven by how their complaints were being handled.
  • Sky again generated the fewest complaints per 100,000 subscribers in both broadband and landline.
  • Sky and TalkTalk were the least complained about pay-TV providers this quarter, receiving the fewest complaints per 100,000 subscribers.
  • O2 was the most complained-about mobile operator, with their complaints again primarily driven by how customers’ complaints were being handled. Sky Mobile, Tesco Mobile, EE and Vodafone received the fewest complaints in the mobile sector.
