A number of the UK's top internet service providers (ISPs) have signed up to a new Voluntary Code of Practice for broadband traffic management.
Sky, BT, TalkTalk, Virgin Media, O2, 3 and Vodafone have agreed to the code, which will require them to be more transparent over how they manage network usage.
Traffic management policies will need to be understandable, appropriate, accessible, current, comparable and verifiable - meaning ISPs could be forced to abandon their vague fair usage policies.
Antony Walker, Chief Executive of the Broadband Stakeholder Group, told ISPreview.co.uk that there has been "more heat than light" in the debate about traffic management over recent years.
As a result, he described this commitment to provide "clear and comparable information" in a common format as "very important".
"It will not only help to ensure consumers are better informed about the services they buy and use, but will also provide a clearer picture for policy makers of the way in which traffic management is actually used in the UK market," Mr Walker commented.
"Consumers need to be able to make informed choices about the services they buy."
