Ofcom's latest complaint data for April to June 2026 highlights which UK broadband providers recorded the highest consumer dissatisfaction rates, with EE and BT among the most complained-about in the broadband sector.
- EE and BT topped broadband complaint figures for Q2 2026
- Plusnet led landline complaints, while O2 saw most mobile grievances
- Broadband remains the sector with the highest complaint rate overall
What happened
Ofcom published complaint statistics for UK communication services covering the second quarter of 2026, from April to June. These figures indicate the number of complaints per 100,000 subscribers across broadband, landline, mobile, and pay-TV sectors. Broadly, complaint volumes decreased compared to the prior quarter, largely due to fewer pay-TV-related complaints.
Within broadband, the highest complaint rates were recorded by EE, BT, TalkTalk, and Vodafone, though some providers saw improvements or declines versus the previous quarter. In landline services, Plusnet had the greatest share of complaints, predominantly regarding complaint handling. Mobile complaints were highest for O2 and Sky Mobile, while EE, Giffgaff, and others had fewer issues reported.
Why it matters
This complaint data provides transparency on customer satisfaction across UK communication providers, helping consumers make more informed choices when selecting services. With broadband attracting the highest complaint rates, it underscores ongoing challenges in service quality, fault management, and customer support within this critical sector.
Ofcom does not intervene in individual complaints but sets regulatory standards providers must follow. Publishing such data applies pressure on providers to improve their service levels and highlight where performance gaps remain, ultimately benefiting consumers and fostering competition in the market.
What to watch next
Stakeholders should monitor whether providers flagged as high-complaint in Q2 2026 respond with improvements in customer service and network reliability in subsequent reporting periods. The trajectory of complaint trends will be a key indicator of provider commitment to resolving consumer issues.
Additionally, shifts in consumer complaint patterns across broadband, landline, mobile, and pay-TV will reveal evolving challenges in the UK communications marketplace, guiding regulatory focus and industry efforts to enhance overall service quality.
