Ofcom has published a new chart detailing the number of consumer complaints made about internet service providers (ISPs) between October 2010 and February 2011.
The media regulator said it received an average of 450 complaints per day during the five-month period.
Among the most common problems reported by broadband subscribers were billing errors, customer service issues and alleged mis-selling.
TalkTalk received 1.27 broadband complaints per 1,000 customers between October and February, with BT (0.61), Sky (0.39) and Virgin Media (0.20) performing better among the major fixed-line ISPs.
Overall, fewer complaints were registered by dongle users - 3 received the highest number at just 0.15 per 1,000 customers, ahead of T-Mobile (0.13) and Orange (0.10), Vodafone (0.09) and O2 (0.04).
Ofcom said the data had been published in order to encourage broadband competition, by letting consumers know about the individual performance of UK ISPs.
The regulator said the information may be useful to those considering switching broadband provider, and also potentially incentivise ISPs to improve the way they operate.
Ed Richards, Chief Executive at Ofcom, stated: "Consumers should have access to as much information as possible to allow them to choose between providers and to take full advantage of the competition in the sector."
