If you don't have BT broadband you could have the mobile app version free with BT mobile plans that come with 6GB data or more, It's app only though so no online player access.
Your other options are if you have Sky TV or TalkTalk TV, you can have the BT Sports pack that way, It also includes app access and the online player.
Other than that the answer is no, your only options are above.
It might be disappointing but what's unfair about it? BT Sport is a commerical product provided by a commercial company which is entitled to call the shots. BT ≠ BBC.
