TalkTalk continued on its growth curve during the final quarter of 2014, adding another 15,000 net broadband customers and 88,000 fibre subscribers.
It was also a good quarter for TalkTalk TV, which acquired another 115,000 connected households, and TalkTalk's mobile offering, which gained 50,000 new customers.
The latest results from the quad-play service provider reveal that customer attrition also fell between October and December 2014, as the total subscriber base reached 4.236 million.
Indeed, the number of consumers choosing to leave TalkTalk fell to its lowest-ever reported level. TalkTalk said this "significant drop" reflects the "continuous effort and investment" it is making in improving the customer experience.
Tristia Harrison, Managing Director of Consumer, said it is "great" to see even more customers make significant savings on their household bills by bundling services together with TalkTalk.
"The response we've seen to our mobile offering makes us excited about the future of quad-play, and the fact that we continue to be Britain's fastest growing TV service demonstrates the huge demand from consumers for flexible, value-for-money packages," she claimed.
"We've always been clear that our mission is to help make families across Britain better off. It's exciting to see our plans accelerating and more TalkTalk homes benefiting as a result."
