BT Openreach has hinted that it may be prepared to reduce the cost of access to its duct and pole network.
Last autumn, media regulator Ofcom ruled that the internet service provider's network access division must enable rival broadband providers to use its existing infrastructure.
However, when BT announced the pricing for network access in January, the firm was accused by some of pricing potential wholesale users out of the market.
BT has now said the price could be reduced, following a three-month service trial involving Sky and Call Flow.
"The trial will allow us to field-test the processes involved in allowing others to use our duct and pole infrastructure, and build upon the accuracy of our assumptions before we launch the product commercially," Openreach Product Director Fergus Crockett said.
"It will also provide our communication provider customers with far greater clarity around the details of deployment, and the likely costs involved, as well as giving them the chance to engage with us around pricing and process development."
