Hi @YamR1rider,
Thanks for posting here in the Roku Community!
We're glad to assist you with your inquiry. You will still be able to use the Roku wireless speaker just fine on your UK TCL Roku TV since Roku's operating system is one. However, you may need to confirm on the TV manufacturer's end (TCL) about the TV's design to see if it is also applicable.
We hope this helps.
Kind regards,
Eunice
