Over 60 per cent of illegal downloads made in the UK are carried out by users of three of the country's ISPs, new figures show.
Industry analysts Envisional have revealed that Carphone Warehouse, Virgin Media and BT are used for 65 per cent of all peer-to-peer (P2P) downloads.
Carphone Warehouse's two broadband providers AOL and TalkTalk saw 22.6 per cent of illegal downloads, Virgin users were responsible for 21.6 per cent and BT subscribers accounted for 21.2 per cent.
The study found 28,000 unique IP addresses are involved in P2P activity.
Michael Phillips, product director at BroadbanChoices.co.uk said it is unsurprising that the three providers experienced increase download figures.
"These three ISPs hold more than 11 million of the UK's 16 million broadband subscribers - BT has 4.5 million customers of its own," he explained. "So it makes sense that they would also have a higher proportion of illegal downloaders."
