TalkTalk posted revenue growth of 4.2 percent in the last three months of 2014 after take-up of new products soared.
Group sales grew to £449 million (€596 million) from October to December after the operator added 253,000 mobile, TV and fibre customers, representing the strongest subscriber growth in the past three years.
TalkTalk added 50,000 mobile customers during the quarter, citing a “strong response” to the launch of quad-play bundles and a new multi-year MVNO deal with O2 that helped it to capture 11 percent of the SIM-only market.
Churn fell to 1.3 percent, with the UK-based company now boasting 398,000 mobile customers in total.
TalkTalk added 88,000 subscribers to its fibre business during the quarter, while its TV customer base ticked over to 1.3 million after it added 115,000 subscribers.
The operator said that it was expecting to add 75,000 broadband and 20,000 voice customers following its acquisition Tesco’s assets earlier this month.
On the enterprise side, revenues were up eight percent to £94 million (€128 million) thanks to a 34 percent increase in data revenues.
Dido Harding, CEO of TalkTalk, said she remained confident of “sustainable growth”.
She added: "Today's results demonstrate the strong and growing demand for our value-for-money products, as we saw our strongest ever quarter of TV, mobile and fibre adds with our lowest ever reported churn.
“We are excited about the future of quad-play. TalkTalk is ideally positioned to push home its strategic advantage in an industry undergoing major changes.”
