Explaining more in post online the BBC explained: "Freeview users may need to retune to find BBC Three, if it’s not already listed in your EPG (electronic programme guide)."
If you are a Sky, Freesat and Virgin customer your box should update automatically and you can instantly tune into the new relaunched BBC channel.
Once you've updated your Freeview device you'll find BBC Three will be available via Channel 23.
