TalkTalk increased its home broadband subscriber base during the final three months of 2013.
The company's latest Interim Management Statement revealed it had a total of 4.186 million broadband subscribers at the end of December.
This was up from 4.076 million in Q3 2013, 4.071 million in Q2 and 4.063 million in Q1.
TalkTalk gained a net 7,000 broadband subscribers organically during the final quarter, plus 103,000 from the Post Office following a network migration.
This included 81,000 fully unbundled, 3,000 partially unbundled and 19,000 off-net customers.
Excluding the Post Office base, TalkTalk increased its fully unbundled base by 49,000 customers, with the legacy partially unbundled and off-net bases reducing by 26,000 and 16,000 respectively.
TalkTalk also achieved strong growth in terms of fibre broadband services.
The company added 35,000 super-fast broadband lines, as many customers upgraded from ADSL TalkTalk broadband deals.
In total, it had 177,000 fibre broadband customers at the end of Q4 2013.
Dido Harding, Chief Executive of TalkTalk, expressed "delight" at the company's performance between October and December 2013.
"We are delighted with the material step up in our revenue growth during the quarter," she stated, explaining that this increased by 5.1 per cent to £436 million.
"[This] shows the powerful effect of combining a modestly growing customer base, disciplined pricing and promotional activity, and strong new product growth," she stated.
Ms Harding said Q4 2013 has been another quarter of "successfully delivering" against TalkTalk's objectives.
"We are confident that we are building a business with strong and sustainable revenue momentum and growing profitability," she added.
