"Satellite customers who take BT broadband will get BT Sport for free, whilst those who don’t can still get the service from BT in high definition for £15 per month or in standard definition for £12. BT will make it clear to those customers they can save substantial sums by switching their broadband back to BT. Satellite customers who sign up before August 1 2013 will see the £3 per month supplement for HD waived for a year."
"To encourage people to switch, BT is offering new customers BT Infinity, its flagship superfast fibre product, from just £15 per month or copper broadband from just £10.00"
So you don't even need to take infinity to get the channels for free. Very interesting for SKY customers.
