In case you've somehow missed the TV adverts, if you have an EE, Orange or T-Mobile phone, you can get 6 months free subscription to BTSport which will give you access to the WTA broadcasts on BT Sport 2. Unfortunately, it only works on the phone, you can sign in on a PC/TV but if your Phone & TV support mirrorcast you should be able to stream it from the phone to the TV. Don't forget to stick a reminder in your calendar to cancel it if you don't want to be charged subscriptions after 6 months though.
