Free app and web access to the channels is standard with all BT broadband packages.
From next week app viewers with a Chromecast dongle will be able to tap the ‘cast’ button to push video from their tablet or smartphone to their TV.
The channels are also available free to BT TV users and Sky viewers who have BT broadband and for £12pm to Sky subscribers who use another ISP.
Virgin Media customers can receive the channels as part of the firm’s XL pack or add them to a lower tier package.
BT’s Pete Oliver said: “We are already delivering BT Sport via our App and we are seeing some impressive viewing figures, which demonstrates that customers appreciate this option.
“Customers with Chromecast will be able to enjoy the BT Sport App, which is free with broadband from BT, on a large screen, allowing customers to cast a Barclays Premier League match to their TV, rather than watching on a smaller screen.
“This helps us to deliver on our aim to bring the best quality sport to BT customers at affordable prices across a wide number of platforms and devices.”
