The most recent data on broadband complaints has been released, bringing both positive and negative updates. Starting with the positive news, the latest statistics from Ofcom indicate an overall improvement in the broadband industry.
According to the UK regulator, complaints against the largest broadband providers in the UK have reached their lowest point on record. The numbers have significantly decreased from a peak of 40 complaints per 100,000 customers in 2011 to just six complaints per 100,000 customers in the first quarter of 2026.
While complaints have decreased overall, there is concerning news for TalkTalk customers, as this provider did not perform as well as its competitors. Ofcom’s data reveals that TalkTalk received the highest number of customer complaints between January and March 2026, making it the most complained-about broadband provider in the UK.
Ofcom stated, “TalkTalk was the most complained-about broadband provider, with complaint levels remaining similar to the previous quarter. Complaints were mainly related to faults, service and provisioning, complaints handling, and issues with billing, pricing, and charges.”
TalkTalk registered 10 complaints per 100,000 customers, surpassing Vodafone (8) and BT (7). On the positive side, Plusnet ranked the best with only four complaints per 100,000 customers, closely followed by Sky with five.
The report by Ofcom also evaluated providers for landline and pay-TV services. For landlines, Utility Warehouse, Sky, Virgin Media, and Vodafone shared the top spot with just two complaints per 100,000 customers. In the pay-TV category, TalkTalk and Sky were the best performers, each recording only two complaints per 100,000 customers.
Cristina Luna-Esteban, Ofcom’s Director of Consumers and Retail Markets, commented, “It’s encouraging to see broadband complaints declining to record lows. Companies should not be complacent and are expected to continuously enhance their services to provide an excellent customer experience.”
Luna-Esteban added, “We encourage dissatisfied customers to consider switching providers. In recent years, we have facilitated easier comparison and savings through end-of-contract alerts, simplified contract summaries, and smoother switching processes for broadband and mobile services.”
