It's available and viewable on my old Samsung TV and on my Humax
HDR-2000T on channel 95, but according to
http://www.a516digital.com/2017/08/faq-new-sports-channel-freesports.html
 
" Freeview/YouView Reception notes:
*Freeview coverage is limited to around 3/4 of the UK. To receive the
channel on Freeview, you need  a device that is compatible with Freeview
HD or Freeview Play and be able to receive channels such as "QVC HD/QVC
Beauty HD" on Freeview 111/112 or "More4+1" on channel 86. If you can't,
you won't be able to see FreeSports."
