The new deal will see the channels show one game free on FreeSports every week, with every other match shown on either Premier Sports 1 or 2. All 152 games will be in HD.
The total value of the new deal to the league, along with separate deals in Ireland and South Africa, is understood to be around £30m. This represents a 100% increase in revenue from the previous three years and will mean a financial boost for each of the competing sides.
Premier Sports 1 is on Sky channel 412 and Virgin channel 551.
Premier Sports 2 is on Sky channel 435 and Virgin Channel 552.
Sister station FreeSports is available free on Sky Channel 422, Virgin Media Channel 553, Channel 95 on Freeview and BT and Freesat Channel 252.
Both Premier Sport channels are available on a subscription basis for £9.99 per month on Sky and on the Premier Sport player.
