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

19 October 2023

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 April to June 2023 (Q2 2023), complaints to Ofcom remained at the same level as the previous quarter (Q1 2023: January to March 2023). Complaints about landline, fixed broadband, mobile pay-monthly and pay-TV all remained unchanged too.

  • Vodafone was the most complained about broadband provider, seeing a substantial rise from the previous quarter. Customers’ complaints were mainly driven by their experience with faults, service and provisioning.
  • TalkTalk, Shell Energy and Virgin Media were the most complained about landline providers. TalkTalk saw a small decrease, Shell Energy remained static and Virgin Media saw a small increase in their complaints per 100,000 subscribers since the previous quarter. Shell Energy’s complaints were mainly driven by customers’ experience with faults, service and provisioning while TalkTalk and Virgin’s complaints were mainly driven by how customers’ complaints were being handled.
  • Sky again generated the fewest complaints per 100,000 subscribers in both broadband and landline.
  • BT Mobile was the most complained-about mobile operator, with customers primarily complaining about how their complaints were being handled and issues changing provider. Sky Mobile, EE and Tesco Mobile received the fewest complaints in the mobile sector.
  • BT and Virgin Media attracted the most complaints about pay-TV. BT’s complaints were mainly driven by customers’ experience with faults, service and provisioning while Virgin’s complaints were driven mainly by how customers’ complaints were being handled. Sky received the fewest pay-TV complaints.
