Your Apple TV will need to run the latest version of tvOS to be compatible with BBC iPlayer.

You can find information on the Apple Support website on how to update your tvOS. Once you’ve updated the tvOS, you’ll then be able to update and access the BBC iPlayer app. Please contact Apple if you require further information.

You can read more about TV certification on the following page: How can I check if BBC iPlayer is available on a particular TV?
