Greetings @chloelouise
Welcome to the Roku Community and thanks for posting regarding channel availability on Roku devices.
Please be aware that many channels on Roku are developed and maintained by the channel provider themselves. For more information about that channel being available on Roku devices, you'd want to contact any specific channel/service provider to inquire further about whether they offer their channel/service on Roku in your region.
Thanks,
Danny
