Wholesale broadband operator Entanet has warned that it would be near impossible to effectively police illegal internet downloads.
According to the provider, implementing reliable monitoring structures could not only lead to increases in price and loss of performance, but also protestations from consumers.
The firm's claim comes on the back of its agreement to trial a new 40Mb broadband connection alongside BT next month.
Darren Farnden, marketing director at Entanet, wrote on the company's blog that monitoring every piece of content which goes through an internet service provider's network would require expensive and protracted investment in new systems and technologies.
He suggested that the idea of operators examining emails for suspicious content was also unlikely to happen.
Figures published by the Strategic Advisory Board for Intellectual Property last month showed that downloads of illegal content via the internet cost the British economy £12 billion per year.
