Sky and Virgin Media racked up fewer complaints to Ofcom than other major broadband providers between April and June.
According to the watchdog, Sky was the subject of just seven complaints per 100,000 customers during the second quarter of 2017.
Virgin Media was ranked in second place, with 13 complaints per 100,000 customers, while EE also performed well, with 15 complaints per 100,000 customers.
All three beat the industry average of 18 complaints per 100,000 customers during Q2, which is down on the previous average of 21 complaints per 100,000 customers in Q1.
Furthermore, this is the second quarter in succession in which Sky, Virgin Media and EE have been named the top performers in Ofcom's customer complaints figures.
However, other providers performed relatively poorly. Plusnet, for instance, was the subject of 20 complaints per 100,000 subscribers, while TalkTalk received 24 complaints per 100,000 subscribers.
Meanwhile, BT was named as the worst performer, with Ofcom receiving 28 complaints per 100,000 customers about the company.
Speaking to BBC News, a BT spokesperson said: "We apologise to customers we've let down.
"We care about service and we've invested heavily to make improvements, including hiring 2,200 extra people, which is helping us answer calls more quickly than ever before - over eight out of ten are now being answered in the UK and Ireland."
Jane Rumble, Director of Consumer Policy at Ofcom, added that while complaints about telecoms firms may be falling this year, some providers are still "falling a long way short on customer service".
She insisted there can be "no room for complacency", as Ofcom expects providers to make service quality and complaints handling their "number one priority", particularly if they have been "consistently under-performing".
