A cyber attack on TalkTalk in October cost the company as much as £80 million (€105m) but fewer customers than feared opted to end their subscriptions.
The numbers affected turned out to be far fewer than originally anticipated, with limited data stolen from approxiamtely 157,000 people, but the bad publicity did cause a spike in defections.
“We saw a big dip inevitably in early November and then the business started returning to normal through December and very much back to normal now,” Chief Executive Dido Harding said.
A total of 101,000 customers left – nearly 3 per cent of the subscriber base. Bigger rivals Sky and BT benefitted from TalkTalk’s problems, adding 144,000 and 130,000 broadband customers respectively in the last three months of 2015.
Five males aged between 15 and 20 were arrested for the cyber attack and freed pending further inquiries.
