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

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 July to September 2023 (Q3 2023), complaints to Ofcom rose slightly from the previous quarter (Q2 2023: April to June 2023). Complaints about landline, fixed broadband and pay-TV all rose from the previous quarter while mobile pay-monthly remained at similar levels.

  • Virgin Media was the most complained about broadband, landline and pay-TV provider, seeing significant rises across all these areas from the previous quarter. Customers’ complaints were mainly driven by how their complaints were being handled.
  • Outside of Virgin Media, NOW Broadband and TalkTalk received more complaints than the industry average in landline whilst NOW Broadband received more complaints than the industry average in broadband.
  • Sky again generated the fewest complaints per 100,000 subscribers in both broadband and landline.
  • TalkTalk and Sky were the least complained about pay-TV providers this quarter, receiving the fewest complaints per 100,000 subscribers.
  • O2 and BT Mobile were the most complained-about mobile operators, with O2’s complaints primarily driven by how customers’ complaints were being handled and BT’s complaints driven by customers’ experiences of changing provider. Sky Mobile, EE and Vodafone received the fewest complaints in the mobile sector.
