Quarterly revenue at Virgin Media rose by 2.4% to €103.8m in September, when compared with the same period last year.
The company said the performance was driven by higher sales, improved customer retention, accelerated network expansion, and continued momentum in its TV3 business.
Virgin also added around 3,500 fixed-line customers and 3,900 mobile customers during the three-month period to September.
Vice-President of Commercial at Virgin Media Paul Farrell said: "Sales of our triple play bundles accelerated during the quarter and our increased investment in Customer service is clearly making a difference with the latest ComReg Customer report showing Virgin Media had the lowest number of complaints per customer compared to all other operators."
On TV3, Mr Farrell said: "We continue to invest in TV3 where we recently launched an improved Autumn schedule while opening an upgraded 3News Ireland Hub to provide viewers with enhanced news and current affairs across the TV3 group channels.
