Chief Executive Tristia Harrison said simplifying the customer offer over the last two years had strengthened the fundamentals of the business. "We are confident in delivering strong headline EBITDA growth both next year and over the medium term," she said.

TalkTalk said a record 152,000 people took its faster fibre products in the final quarter of the year.

Harrison said 40% of its 4.3 million customer base now had superfast broadband, and she expected it to rise to 60% in the next 12 months driven by the ever rising demand for video content on Netflix, Amazon and YouTube.

TalkTalk is building its own fibre-to-the-premise network in the northern city of York and three additional towns, but it has a more ambitious plan to build a network serving 3 million premises with an investment partner.

Harrison said TalkTalk had received a lot of interest in the network plan, and an information memorandum was going out to potential investors this week.

"We'd like to have it complete by the end of the first half, so the end of September," she said.

Shares in TalkTalk were trading down 0.3 percent at 115 pence in morning deals.
